Definitions

  • Clothing capable of masking traces of body moisture and the method of manufacture thereof
  • Office clothes and sportswear made of specially treated fabric with double-sided treatment.
  • Functional sportswear is adapted primarily to the rapid removal of sweat from the body to prevent long-term contact of moisture with the skin, which not only reduces the comfort of an athlete, but may also cause health problems in the form of chilling, cold, and the like. Functional sportswear usually does not focus on aesthetics but function. So, the result is, “I feel great, I feel being dry; however, everyone can see how sweaty I am.” Sportswear or fabrics intended for sportswear form an extensive state of the art, and we do not aim to discuss them extensively herein. We focus on clothing or fabrics that have double-sided surface finish with different properties.
  • the condition for one-way moisture direction is the arrangement of the hydrophilic and hydrophobic visible moisture-masking layer with respect to the user’s skin.
  • the reverse layer of the fabric/clothing intended for contact with the user’s skin is always hydrophobic so that moisture does not remain in it but only passes quickly to be drained away.
  • CN 100414 036 describes a fabric which is provided with a hydrophobic print on the reverse side, which covers 50 to 99% of the reverse side.
  • CN 101 845 702 describes a method for treating a fabric, the reverse side of which, like in CN 100414 036, is provided with a hydrophobic print which, unlike CN 100414036, covers the entire surface of the fabric reverse side.
  • the fabrics manufactured in accordance with CN 100414 036 or CN 101 845 702 are intended for the production of sportswear, fast removal of sweat from the body and fast drying.
  • CN 100414 036 and CN 101 845 702 address the problem: How to feel well during exercise/sport and be dry soon?
  • the clothing of this invention which is preferably worn directly on the user’s skin.
  • the clothing On the right side, the clothing is provided with a hydrophobic visible moisture-masking layer which is partially coated/soaked into the fabric; and on the reverse side, it is provided with a hydrophilic layer which quickly and efficiently receives and distributes the body moisture over the hydrophilic layer.
  • the wearer feels certain moisture compared to sports functional T-shirts, which does not, however, disturb the user’s comfort. The moisture is absorbed and distributed within the hydrophilic layer and evaporates through the hydrophobic layer.
  • An essential feature of the clothing of this invention is that no moisture reservoirs are formed in the right, surface, hydrophobic, visible moisture-masking layer, and the moisture does not accumulate there in any way; it only passes to the surface where it evaporates.
  • the hydrophobic layer is incorporated into at least 30% of the fabric thickness to be able to visually mask the moisture. Thus, no stains, maps or marks are visible on the right side, and the wearer may focus on the object of their interest, having peace of mind.

  • the clothing When dressed, the clothing is designed so that the reverse side is in contact with the body skin and can distribute the discharged body moisture over the hydrophilic surface thereof, which is formed by hydrophilic treatment of the knitted fabric and serves as a reservoir of body moisture to distribute body moisture within hydrophilic area thereof and, at the same time, retain it therein; the boundary thereof is delimited by a hydrophobic surface area, which is formed by the hydrophobic treatment of the knitted fabric and serves to mask and enclose the moisture in the hydrophilic space of the knitted fabric.
  • this hydrophobic area allows moisture to evaporate from the hydrophilic area, water molecules pass freely through it but are not able to be trapped.

  • Drop test absorbency is a method designed to measure the water absorbency of fabric by measuring the time it takes a drop of water placed on the fabric surface to be completely absorbed by the fabric. Sample is placed over the top of the beaker so that the centre is unsupported. A measured drop of water is placed on the fabric from 1 cm off the surface, time is recorded until the water drop gets absorbed completely. The less seconds, the better absorbency.

It was found that, despite the fact that the T-shirt still contains 139.2 g of soaked mineral water, the shade of the right side of the T-shirt corresponds to the shade of the dry T-shirt. Since the penetration of the hydrophobic paste in Example 5 was carried out to half the thickness of the knitted fabric 1, it was calculated that 63.6 g of the hydrophobic surface finish 2 of the knitted fabric 1 could mask 139.2 g of moisture, i.e., 2.19 times of its own weight. The test results are shown in Figure 7. The deviation of the T-shirt weight per square metre from the footage is caused by the presence of stitches and information appliques. List of marks for terms

Description

Clothing capable of masking traces of body moisture and the method of manufacture thereof
Field of the Invention
Office clothes and sportswear made of specially treated fabric with double-sided treatment.
State of the Art
At present, a distinction is made between clothing intended for sports and clothing intended for the office or other semi-social gatherings. Functional sportswear is adapted primarily to the rapid removal of sweat from the body to prevent long-term contact of moisture with the skin, which not only reduces the comfort of an athlete, but may also cause health problems in the form of chilling, cold, and the like. Functional sportswear usually does not focus on aesthetics but function. So, the result is, “I feel great, I feel being dry; however, everyone can see how sweaty I am.” Sportswear or fabrics intended for sportswear form an extensive state of the art, and we do not aim to discuss them extensively herein. We focus on clothing or fabrics that have double-sided surface finish with different properties. Due to the double-sided treatment of fabrics, effective one-way moisture direction is ensured for sportswear, followed by easy moisture evaporation from the fabric. The condition for one-way moisture direction is the arrangement of the hydrophilic and hydrophobic visible moisture-masking layer with respect to the user’s skin. The reverse layer of the fabric/clothing intended for contact with the user’s skin is always hydrophobic so that moisture does not remain in it but only passes quickly to be drained away. The right layer of fabric/clothing intended to be directed away from the body is always hydrophilic in order to accelerate the moisture removal from the body, wherein the moisture is taken away from the skin through the hydrophobic layer into the hydrophilic layer where the moisture is evaporated. Moisture is thus transported as quickly as possible from the body towards the clothing surface, where it is evaporated. Double-sided treatments of fabrics with different properties are described, for example, in CN 100414 036 or CN 101 845 702.
CN 100414 036 describes a fabric which is provided with a hydrophobic print on the reverse side, which covers 50 to 99% of the reverse side.
CN 101 845 702 describes a method for treating a fabric, the reverse side of which, like in CN 100414 036, is provided with a hydrophobic print which, unlike CN 100414036, covers the entire surface of the fabric reverse side. The fabrics manufactured in accordance with CN 100414 036 or CN 101 845 702 are intended for the production of sportswear, fast removal of sweat from the body and fast drying. CN 100414 036 and CN 101 845 702 address the problem: How to feel well during exercise/sport and be dry soon?
If we abandon sportswear and look at the current solutions to the problem: How to look well even when feeling sweaty and wet? Especially in summer, temperatures in buildings exceed the tolerable level and the emphasis is on formal wear. In such situations, the current market offers only one solution, being absorbent under-T-shirts or singlets. Absorbent pieces of clothing are worn as underwear under shirts, T-shirts or dresses and are designed to retain maximum body moisture so that this moisture does not seep into outerwear to form sweat marks. Some companies offer an absorbent under-T-shirts with reinforced risk areas, where, for example, a highly absorbent pad is sewn into the under-T-shirt at the place of contact with the armpit, which can hold more sweat than a single-layer absorbent under-T-shirt or singlet. Such a solution solves the problem of “How to look good”; however, at the cost of very high discomfort when wearing such absorbent under-T-shirts, when an individual dressed in two layers of clothing is much warmer and sweats even more. At the same time, all body moisture remains soaked in the under-T-shirt, which is placed directly on the skin, so the individual feels wet.
Description of the Invention
How to look good even on hot days, in an overheated office or during an important meeting? And moreover, how to feel well about it? How to make body moisture invisible on clothing? Using the clothing of this invention, which is preferably worn directly on the user’s skin. On the right side, the clothing is provided with a hydrophobic visible moisture-masking layer which is partially coated/soaked into the fabric; and on the reverse side, it is provided with a hydrophilic layer which quickly and efficiently receives and distributes the body moisture over the hydrophilic layer. Thus, the wearer feels certain moisture compared to sports functional T-shirts, which does not, however, disturb the user’s comfort. The moisture is absorbed and distributed within the hydrophilic layer and evaporates through the hydrophobic layer. An essential feature of the clothing of this invention is that no moisture reservoirs are formed in the right, surface, hydrophobic, visible moisture-masking layer, and the moisture does not accumulate there in any way; it only passes to the surface where it evaporates. The hydrophobic layer is incorporated into at least 30% of the fabric thickness to be able to visually mask the moisture. Thus, no stains, maps or marks are visible on the right side, and the wearer may focus on the object of their interest, having peace of mind. The clothing of this invention is preferably worn directly on the user’s skin.
Clothing was created that masks traces of body moisture and is intended for contact with the skin. This clothing, preferably a T-shirt, underwear, comprises at least one layer of knitted fabric, which is provided with a hydrophobic surface finish of the knitted fabric, which can completely mask the body moisture of a user thereof, namely at least 2 times the weight of water compared to the actual weight of the knitted fabric and at the same time ensure gradual evaporation of moisture from the body. With a light T-shirt, it masks up to 180 ml of sweat per m2, i.e., 140 ml of sweat for an average ready-made clothing.
When dressed, the clothing is designed so that the reverse side is in contact with the body skin and can distribute the discharged body moisture over the hydrophilic surface thereof, which is formed by hydrophilic treatment of the knitted fabric and serves as a reservoir of body moisture to distribute body moisture within hydrophilic area thereof and, at the same time, retain it therein; the boundary thereof is delimited by a hydrophobic surface area, which is formed by the hydrophobic treatment of the knitted fabric and serves to mask and enclose the moisture in the hydrophilic space of the knitted fabric. However, this hydrophobic area allows moisture to evaporate from the hydrophilic area, water molecules pass freely through it but are not able to be trapped. This hydrophobic surface finish of the knitted fabric preferably contains 4 to 10% wt. of hydrophobic mixture in the weight per square metre.
Thus, the hydrophobic surface finish of the knitted fabric leads to the outside of the clothing, the hydrophilic surface finish of the knitted fabric leads to the inside of the clothing and is intended to come into contact with the skin; the hydrophobic and hydrophilic surface finishes meet inside the knitted fabric layer, wherein the hydrophobic surface finish of the knitted fabric delimits the boundary of the hydrophilic surface finish of the knitted fabric.
The hydrophobic surface finish of the knitted fabric masks the moisture in the hydrophilic surface finish of the knitted fabric so well that it is not visible to a naked eye that the knitted fabric contains water; and, at the same time, the moisture is locked in the hydrophilic layer as it forms the boundary, beyond which the water does not rise along the fibres.
The clothing is made of knitted fabric - a textile flat knitted structure (hereinafter referred to as “knitted fabric”), which is treated on both sides and each side has different properties. The right side of the knitted fabric is provided with a hydrophobic surface finish of the knitted fabric, visible, moisture-masking, which is applied in the form of a paste on/into the knitted fabric using a perforated rotary template. The viscosity of the hydrophobic paste is adjusted so that the hydrophobic paste soaks up to 30 to 70% of the knitted fabric thickness, preferably to half the knitted fabric thickness, providing effective visual masking of body moisture and also ensuring distribution of moisture in the remaining 70 to 30% of the knitted fabric thickness. A functional variant of the knitted fabric is a cotton knitted fabric with at least 90% wt. of cotton weighing at least 150 g/m2. It is always desirable to achieve the soaking of the hydrophobic paste to approximately half the knitted fabric thickness, but at least up to 30%, in order to form a visually masking hydrophobic layer. The use of a knitted fabric is very preferable because the knitted fabric distributes moisture well, helping the clothing to function even better.
After the right side of the knitted fabric is provided with a hydrophobic surface finish of the knitted fabric, visually moisture-masking, the whole knitted fabric is preferably treated with a softening solution or an antibacterial solution. By applying the softening solution, the hydrophilic properties and user comfort of the untreated reverse side of the knitted fabric are improved and the hydrophobic surface finish of the knitted fabric is softened.
Then, the clothing, such as urban T-shirts, shirts, T-shirts under shirts, or underwear or trousers, is made from the knitted fabric treated on one side or both sides; layer orientation with respect to the body must be followed - i.e., hydrophilic surface finish on the reverse side of the knitted fabric as well as the clothing comes into contact with the skin. The outer right side of the knitted fabric and clothing is hydrophobic. In addition to the masking function, the hydrophobic surface finish on the right side of the knitted fabric has a water-repellent function. This is especially useful for outerwear such as T-shirts or shirts, where they can be spilt on or soiled with drinks or food at any time, wherein liquids freely flow down the hydrophobic knitted fabric and food pastes - such as ketchup or mustard - can be easily wiped off the clothing without they left stains. Thus, the clothing masking traces of body moisture, intended for contact with the skin, comprises at least one layer of the knitted fabric containing at least 90% wt. of cotton, weighing 150 g/m2, which is treated only with preparations without cationic substances,
The knitted fabric is provided with a hydrophobic, moisture-masking and locking surface finish of the knitted fabric situated to a depth of 30 to 70% of the knitted fabric from the right side of the knitted fabric, and a hydrophilic, moisture-distributing and retaining surface finish of the knitted fabric situated to a depth of 30 to 70% of the knitted fabric from the reverse side of the knitted fabric.
The hydrophobic surface finish of the knitted fabric consists of a hydrophobic mixture which constitutes 4 to 10% wt. of the clothing, and the hydrophilic surface finish of the knitted fabric has a drop test absorbency of at most 5 seconds, preferably 3 seconds; the hydrophobic surface finish of the knitted fabric masks at least 2 times of weight of water retained in the hydrophilic surface finish of the knitted fabric, regarding the weight thereof.
Drop test absorbency is a method designed to measure the water absorbency of fabric by measuring the time it takes a drop of water placed on the fabric surface to be completely absorbed by the fabric. Sample is placed over the top of the beaker so that the centre is unsupported. A measured drop of water is placed on the fabric from 1 cm off the surface, time is recorded until the water drop gets absorbed completely. The less seconds, the better absorbency.
The hydrophilic surface finish of the knitted fabric leads to the reverse inner side of the clothing and the hydrophobic surface finish of the knitted fabric leads to the right outer side of the clothing and the interface of the hydrophobic and hydrophilic surface finishes of the knitted fabric is situated inside the layer of the knitted fabric.
The hydrophobic mixture preferably contains at least 10% wt. of fluorocarbon and at least 50% wt. of a polymeric carrier, wherein the polymeric carrier is acrylate and the derivatives thereof or polyurethane and the derivatives thereof, or acrylate-polyurethane and the derivatives thereof.
Alternatively, the hydrophobic mixture preferably contains 70 to 99% wt. of a copolymer of fluorocarbon and acrylate and 1 to 30% wt. of polyurethane. The fluorocarbon used consists of a carbon chain with a length of 4, 6.
Alternatively, the hydrophobic mixture preferably contains 60 to 100% wt. of resins or paraffins.
The knitted fabric preferably contains at least 95% wt. of cotton and at least 2% wt. of Lycra. General procedure for the manufacture of clothing capable of masking traces of body moisture
Pre-treatment:
The carrier fabric is a flat textile structure - a knitted fabric. Preferably a single or double knitted fabric is used. The knitted fabric is made of at least 90% wt. of cotton, preferably 95% wt. of cotton and the weight per square metre thereof is 150 to 300 g/m2, preferably 160 g/m2. Lycra, viscose, or synthetic fibres are preferably used as an additive. The knitted fabric must always meet the condition of absorbency -drop test - maximum 5 seconds, preferably 3 seconds. This absorbency condition precludes the use of more than 10% wt. of the content of synthetic fibres in the knitted fabric.
The pre-treatment of the knitted fabric is carried out according to state of the art, complying with the given conditions. The pre-treatment is preferably carried out using a continuous or pull-out method and consists of treating the fabric with a stabilizer and a wetting agent. Preferably, hydrogen peroxide and lye, preferably NaOH, are added during the pre-treatment. Peroxide and lye are added to treat raw cotton, wherein it is bleached and unwanted particles adhering to the fibres are removed. When using peroxide and lye, the knitted fabric must be washed at least at 70 °C for at least 25 minutes at the end of the pre-treatment. No cationic substances must be applied in the pre-treatment step and any treatment agents used must remain stable in all subsequent steps, especially when exposed to temperatures of about 160 °C.
Dyeing:
The dyeing of the knitted fabric is carried out according to state of the art, complying with the given conditions. The dyeing is preferably carried out using a continuous or pull-out method and consists of dyeing the fabric with a textile dye. Preferably, an environmental-friendly non-sulfone textile dye having low water consumption and low carbon footprint is used. In addition to the dye itself, an antifoaming agent, levelling and anti -refraction agents, salt, and alkali are preferably used. No cationic substances, in particular silicone or hydrophobic agents impairing the natural absorbency of the cotton, must be applied in the dyeing step and any treatment agents used must remain stable in all subsequent steps, especially when exposed to temperatures of about 160 °C.
At the end of the dyeing step, the dyed knitted fabric is preferably fixed on a frame and dried. Application of hydrophobic, visible moisture-masking surface finish of the knitted fabric:
The hydrophobic paste contains up to 10% wt. of the hydrophobic mixture, wherein the hydrophobic mixture contains 70 to 99% wt. of a copolymer of fluorocarbon and acrylate and 1 to 30% wt. of polyurethane. Or the hydrophobic mixture contains at least 10% wt. of fluorocarbon and at least 50% wt. of a polymeric carrier, wherein the polymeric carrier is acrylate and the derivatives thereof or polyurethane and the derivatives thereof, or acrylate- polyurethane and the derivatives thereof.
The hydrophobic mixture is preferably in the form of an aqueous dispersion of a hydrophobic mixture with a dry matter content of 40 to 50% wt., preferably an aqueous dispersion of a copolymer of fluorocarbon and acrylate in a polyurethane carrier.
C4, C6 fluorocarbon is preferably used. When fluorocarbon is used, the finished knitted fabric features repellent characteristics not only for water or wine but also for oils and paste mixtures, such as ketchup or honey. Furthermore, the hydrophobic paste contains water and is thickened using textile thickening agent to the desired viscosity. The thickening agent is preferably made of polysaccharides, in particular starches, seaweed, or acrylic or maleic acid derivatives. Preferably, the thickening agent is a polymer dispersion of 3 to 10% wt. of ethoxylated branched tridecanol, 1 to 10% wt. of C11-C15 alkanes and water. Preferably, the hydrophobic paste additionally contains less than 5% wt. of an effective ingredient, which may be a dye or an antibacterial agent.
The hydrophobic paste is first mixed without thickening agent, usually to a viscosity of about 55 to 75 dPa s, preferably 60 to 65 dPa s, and mixed for at least 15 minutes. After 15 minutes, the paste is thickened to a viscosity of 80 to 90 dPa s, preferably 83 to 85 dPa s using the thickening agent.
The hydrophobic, visible moisture-masking surface finish of the knitted fabric is applied/coated on the right side of the knitted fabric by means of a rotary template having perforation/porosity of 100 to 200 mesh, preferably 125 to 195 mesh, in a dose of 110 to 200 g/m2 of the knitted fabric, preferably in a dose of 110 to 130 g/m2 of the knitted fabric weighing 150 to 180 g/m2, and in a dose of 130 to 200 g/m2 of the knitted fabric weighing 180 to 300 g/m2. The rotary template is a rotating hollow cylinder, which preferably has a diameter of 15 to 40 cm, and shell of which is perforated/porous. The template is mounted on a dosing device dosing the hydrophobic paste into the rotary template. The rotary template is fitted with a squeegee used to gather the hydrophobic paste and push it through the rotary template pores, wherein the hydrophobic paste is coated into the knitted fabric. The rotating rotary template is placed loosely on the fabric without pressure or with a maximum pressure of 0.5 bar and rotates together with the knitted fabric being unwound. The rotary template is shown in Figure 3. After coating the hydrophobic paste with the rotary template into the knitted fabric, the applied paste is preferably smoothed with a smoothing squeegee or knife without pressure or with a maximum pressure of 0.5 bar over the entire width thereof.
Drying and condensation of hydrophobic, visible moisture-masking surface finish of the knitted fabric:
The hydrophobic paste applied to the knitted fabric and smoothed is first dried at 110 to 130 °C for 30 to 90 seconds to ensure each piece of the knitted fabric is dry. Only then, the dried hydrophobic paste applied to the knitted fabric is exposed to temperatures of 150 to 170 °C for 60 to 120 seconds, depending on the form of carrier used in the hydrophobic paste. Preferably, the hydrophobic, visible moisture-masking surface finish of the knitted fabric is dried at 120 °C for 60 seconds and condensed at 160 °C for 90 seconds. Drying and condensation may be performed in two steps or a single step, but it is always necessary to ensure the knitted fabric exposed to condensation temperatures is completely dry. After finishing the condensation, the knitted fabric becomes hydrophobic on one side, namely on the right side thereof. The reverse side keeps the properties of the knitted fabric before the one-side application of the hydrophobic paste, i.e., it remains hydrophilic.
At this point, it is possible to stop the manufacture since the knitted fabric is hydrophilic on the one side and hydrophobic on the other side. The final manufacture step includes spatial stabilization of the knitted fabric called sanforising, wherein the sanforising is performed according to the state of the art. However, for the user comfort, it is preferable to include at least one of the following steps before sanforising:
Preferable softening treatment of the knitted fabric:
The whole knitted fabric, in particular, the reverse side thereof, is very preferably treated with a softening solution, supporting the knitted fabric hydrophilicity and the user comfort when wearing clothing made of such a knitted fabric. The knitted fabric with the condensed hydrophilic surface finish is treated with cationic substances to increase the hydrophilicity and soften the fabric for feeling tone. The knitted fabric having the condensed hydrophilic surface finish is preferably treated with a softening solution, which contains surfactants and/or silicones, contains preferably a silicone microemulsion in the form of polydimethylsiloxane in a concentration of at least 10 g/kg of the softening solution, using a pull-out or continuous method. Further, the softening solution contains ethoxylated isotridecanol at a concentration of 1 to 5 g/kg of the softening solution and sodium toluenesulfonate at a concentration of 0.2 to 0.8 g/kg of the softening solution. The pH value of the softening hydrophilic solution ranges preferably between 5 and 6, which is achieved by the addition of acetic acid. After treatment with the softening solution, the knitted fabric is dried at 120 to 140 °C for 30 to 90 seconds, preferably at 130 °C for 60 seconds.
Preferable effect treatment of the knitted fabric:
Preferably, an effect treatment is applied to the double-sided treated knitted fabric with different properties, which may be an application of an antibacterial solution, preferably containing silver, zinc, copper, or cobalt. Zinc is preferably applied in the form of pyrithione zinc. Preferably, the application of the antibacterial solution is performed instead of the hydrophilic treatment of the knitted fabric.
Cutting and sewing the clothing:
After sanforising, the treated knitted fabric is cut according to the patterns and sewn, preferably with cotton threads, into shapes of the desired piece of clothing. Preferably, socks, underwear, singlets, vests, petticoats, T-shirts, shirts, polo shirts, or caps are made.

Example 7: Testing the moisture masking of the clothing
The ability of clothing to mask moisture was tested on the urban T-shirt made according to Example 5 according to the protocol for the water binding capacity of fabrics. A T-shirt of size M with an area of 0.78 m2 was weighed in the dry state. The T-shirt was then completely immersed in mineral water simulating the composition of body sweat the best and allowed to soak for 5 minutes. Then the T-shirt was removed from the water and allowed to drip. As soon as the water stopped dripping from the T-shirt, or the interval between drops was longer than 1 min, the T-shirt was re-weighed. It was found that a T-shirt having an area of the knitted fabric 1 of 0.78 m2 holds 196.5 ml of water. The T-shirt was then hung on a hanger and allowed to dry slowly. The T-shirt was re-weighed every 15 minutes, and the shade of the right side of the test T-shirt and the one of a dry T-shirt were compared by image analysis. It was found that, despite the fact that the T-shirt still contains 139.2 g of soaked mineral water, the shade of the right side of the T-shirt corresponds to the shade of the dry T-shirt. Since the penetration of the hydrophobic paste in Example 5 was carried out to half the thickness of the knitted fabric 1, it was calculated that 63.6 g of the hydrophobic surface finish 2 of the knitted fabric 1 could mask 139.2 g of moisture, i.e., 2.19 times of its own weight. The test results are shown in Figure 7. The deviation of the T-shirt weight per square metre from the footage is caused by the presence of stitches and information appliques. List of marks for terms
