Description

Single-sided knitted fabric

The invention relates to a single-sided knitted fabric, specifically a single-sided knitted fabric with a function of water absorption and quick-drying.

With the continuous improvement of living standards, people's requirements for wearing comfort are becoming higher and higher, and ordinary water-absorbent and quick-drying products have been unable to meet the public's needs. Especially during exercise, the human body will produce a lot of sweat. If these sweats cannot be absorbed and discharged in time and completely, the fabric will be wet and stick to the skin, and the discomfort will be particularly serious.

So far, most researches have been done on the water absorption and quick-drying properties of fabrics. For example, Japanese Patent Laid-Open No. 10-131000 discloses a double-faced knitted fabric having a concave-convex structure with a height difference of 0.2 mm or more and 2 mm or less on the back side, wherein the concave portion is composed of monofilament fineness of 1 denier and 5 denier It is composed of slime filaments below polyester or polyester/viscose blended filaments. The convex and front sides are made of polyester filaments. This knitted fabric can reduce the sultry feeling and stickiness after sweating. Japanese Patent Document No. 2011-256495 discloses an absorbent fabric. The fabric is a double-layer knitted fabric or woven fabric, the surface layer is formed of hydrophilic yarns, the inner layer is formed of hydrophilic yarns and hydrophobic yarns, and the shrinkage rate of the hydrophilic yarns in the inner layer is hydrophobic More than 5% of the yarn is designed with a hydrophilic surface and a partially hydrophobic inside to achieve the purpose of quick drying. However, due to the double-layer design of these technologies, there is more water-retaining space between the yarns, and the sweat conduction channel is also relatively long, resulting in a longer time for the water to diffuse, and quick-drying needs to be further improved.

In addition, Chinese patent document CN103668732A discloses a unidirectional wetting fast by using cotton yarn as the inner layer material, "Y" cross-section ultra-fine Danny polyester filament as the outer layer material, and a plain weave single-sided structure for weaving. Dry cotton/polyester composite knitted fabric. The poor moisture permeability of the yarns on the front and back layers guides the sweat on the outer surface to the outer layer and quickly evaporates, keeping the inner layer of the fabric dry. However, because the inner layer is made of cotton with high water retention, it is difficult to ensure the dryness of the skin and the wearing comfort is poor.

In addition, Japanese Patent Document No. 5596886 discloses a fabric including a fiber A without water repellency and a fiber B with water repellency, wherein the weight ratio of fiber A to fiber B is 50:50~87:13 Within the scope, this kind of cloth has the characteristics of water absorption, water repellency and easy to float on the water surface, but this document does not propose a solution for quick drying.

The object of the present invention is to provide a single-sided knitted fabric which has excellent water absorption and quick-drying properties, and can maintain the dryness of the skin surface.

The knitted fabric of the present invention is a weft knitted fabric with a single-sided structure, including a surface and an inner surface, wherein the inner surface is formed by alternately arranging hydrophobic yarns and hydrophilic yarns A along the weft direction loops, and provided on the inner surface Hydrophobic part.

The knitted fabric of the present invention has the function of quickly absorbing sweat and exporting it to the surface, and then quickly spreading on the surface, and at the same time can keep the dry feeling from time to time, so as to avoid the discomfort of sticking to the skin after sweating. It is especially suitable for making sweaty clothes such as T-shirts and sportswear for summer.

FIG. 3 is a schematic diagram of the yarn adding structure of Embodiment 2 of the present invention.

The knitted fabric of the present invention is a weft knitted fabric with a single-sided structure. Compared with a double-sided knitted fabric formed by yarns with the same fineness, the knitted fabric has obvious advantages of lightness and thinness and is more conducive to sports. On the other hand, the perspiration-conducting channel of the single-sided tissue fabric is relatively short, which does not cause the problem of sweat retention after sweat absorption like the double-sided tissue fabric, and the quick-drying is better.

The knitted fabric of the present invention includes a surface and an inner surface, wherein the inner surface is formed by alternately arranging hydrophobic yarns and hydrophilic yarns A along the weft loop, and the hydrophobic portion is formed by the hydrophobic yarns on the inner surface The sexual yarn forms a hydrophilic portion. Here, the so-called weft stitches are alternately arranged at intervals, which means that the hydrophilic yarns and the hydrophobic yarns 1 are alternately arranged with each other. The molecular structure of the hydrophobic yarn is relatively tight, and the water molecules are not easy to enter the fiber. The moisture (sweat) on the skin is concentrated toward the hydrophilic part and is absorbed and transmitted, ensuring the dryness inside the fabric, even if the amount of sweat is large The fabric adheres to the skin. If all the hydrophilic yarns inside can absorb sweat, the absorbed sweat will cause the fibers to moisten and make the fabric stick to the skin. On the contrary, if all the hydrophobic yarns are inside, the sweat stays on the skin surface and cannot be exported in time, which will also cause the problem of the fabric sticking to the skin.

In the present invention, the hydrophobic portion refers to a portion that does not have the function of absorbing moisture. The hydrophilic part refers to a part that has the function of quickly absorbing sweat produced by the human body and conducting it to the surface.

After the sweat is absorbed by the hydrophilic yarn A inside, it must be conducted to the surface as soon as possible. Compared with the case of using the hydrophobic yarn on the surface, if the hydrophilic yarn B is used, the absorption conductivity and surface diffusivity of the sweat are more Good, it can accelerate the drying speed of the hydrophilic part inside, so it is better.

In the present invention, the so-called hydrophilic yarn means that 6 to 8 yarns are visually arranged side by side without gaps to form a yarn bundle, and a drop of water is dripped from a dropper 1 cm directly above, and the water can be removed in 60 seconds. Completely absorbed yarn. The hydrophobic yarn in the present invention refers to a yarn that fails to completely absorb water within 60 seconds according to the above method.

The hydrophilic yarn A (or hydrophilic yarn B) is a yarn with hydrophilicity or a yarn with a hydrophilic resin attached to the surface, and the hydrophobic yarn is a yarn with hydrophobicity or a dial is attached to the surface Water resin yarn.

When the hydrophilic yarn A (or hydrophilic yarn B) is a yarn that is itself hydrophilic, the fiber raw material may be one or more of cotton, mucus, polyamide (Ny), etc.

When the hydrophilic yarn A (or hydrophilic yarn B) is a yarn with a hydrophilic resin attached to the surface, the hydrophilic resin is obtained by moderate crosslinking of monomers with strong hydrophilic groups, which is absorbable The type of the resin with a moisture of hundreds to thousands of times is not particularly limited, and it may be a water-based polyurethane resin, a water-based acrylic resin, a water-based polyester resin, or the like. In the present invention, the yarn with hydrophilic resin attached to it can be made of ordinary polyester (PET), polybutylene terephthalate (PBT), polytrimethylene terephthalate (PTT), cationic modification One or more of polyester (CDP) and the like.

In the present invention, the fiber materials of the hydrophilic yarn A and the hydrophilic yarn B may be the same or different. Preferably, the hydrophilic yarn A is the same as the hydrophilic yarn B, and both are yarns with a hydrophilic resin attached to the surface.

When the hydrophobic yarn in the present invention is a yarn with a water-repellent resin attached to its surface, the fiber raw material may be one with water-repellent properties, and the water-repellent resin here may be derived from paraffins, silicones, hydrocarbons , Fluorine, etc. Among them, fluorine may be C4, C6, C8 and so on.

When the hydrophobic yarn in the present invention is a yarn with inherent hydrophobicity, the fiber raw material may be one or more of PET, PBT, PTT, CDP, polypropylene (PP), and the like. Among them, PP fiber includes ordinary unmodified PP fiber, dyeable PP fiber, colored PP fiber (color masterbatch coloring), etc. Dyeable PP fibers are obtained by uniformly dispersing dyeable polymers (polyesters or polyamides, etc.) in PP resin and extruding and spinning. Colored PP fiber is made by mixing color masterbatch and polypropylene resin in a certain ratio and melt spinning. PP fiber is the chemical fiber with the lowest density, especially the fine Danny PP fiber has super-hydrophobicity, low moisture regain, strong moisture conductivity and unique wicking effect, and PP fiber is not easy to chemically react with conventional hydrophilic chemicals They are combined to become hydrophilic, that is, even if the hydrophilic resin is processed during finishing, it does not affect its hydrophobicity, so it is preferable. These fiber raw materials can be used as they are, or they can be synthesized according to a technique known in the art.

The knitted fabric of the present invention is preferably a yarn adding structure or a padding structure. Among them, in consideration of the index performance of the dynamic moisture transfer method, the smoothness and comfort of the fabric, it is preferable to add yarn.

Considering that if the area of the hydrophilic part on the inside of the fabric is too large, it may affect the dryness of the skin; on the contrary, if the hydrophobic part dominates on the inside, sweat may be difficult to be absorbed in time. In the present invention, it is preferable that the area ratio between the hydrophobic portion and the hydrophilic portion on the back surface of the fabric is between 1: 1.0 and 4.0 in a tension-free state. More preferably, the area ratio of the two is 1:1.0~2.0.

Preferably, on the inner side of the fabric of the present invention, the length of the hydrophilic yarn is longer than that of the hydrophobic yarn. Compared with the loop formed by the hydrophobic yarn, the loop formed by the hydrophilic yarn is large and fluffy. The hydrophilic portion formed by this loop is close to the skin, which is more conducive to wicking and perspiration when sweating. In the present invention, the thread length of the better hydrophilic yarn is 5% to 15% than that of the hydrophobic yarn.

In the present invention, the monofilament fineness ratio between the hydrophilic yarn B on the surface and the hydrophilic yarn A on the inner surface is preferably 1: 1.1 to 4.0. Preferably, the monofilament fineness ratio between the hydrophilic yarn B on the surface and the hydrophilic yarn A on the inside is 1:2.0~3.5. Because the monofilament fineness of the surface yarn is finer than that of the inner filament, the surface yarn is denser than the monofilament gap (capillary) of the inner yarn, and the capillary wicking effect is more obvious, so the sweat inside can also be more Conducts well to the surface and spreads quickly. The finer the monofilament fineness of the surface yarn, the smaller the gap (capillary) between the monofilaments can be formed, and the better the water absorption effect.

In the present invention, the hydrophilic yarn B on the surface is preferably a filament multifilament of 50 to 150 denier (abbreviated as D) or a spun yarn of 30 to 80 inch count (abbreviated as S). When choosing a filament multifilament less than 50 denier or a spun yarn thinner than 80S, if the inner yarn is thicker than the surface yarn, there may be a problem of poor knitting such as reverse yarn. The layering becomes unclear, and the dryness of the skin tends to be reduced; if the lining uses a thinner yarn than the surface yarn, although there is no problem of reverse silk, the fabric is thin and the fabric is soaked and sticks. The possibility of problems on the skin. When choosing a filament multifilament greater than 150D or a spun yarn thicker than 30S, if the lining uses a yarn of the same thickness as the surface yarn, the layering of the surface layer becomes unclear and the dryness of the skin is reduced. Tendency; and the resulting fabric is thicker, limited use. If the inner yarn is thinner than the top yarn, the inner layer structure is not obvious, and there is a possibility that the sweat treatment on the skin surface cannot be achieved, which affects the dry feeling.

The knitted fabric of the present invention can be obtained by weaving colored yarns, or can be obtained by dyeing gray fabrics. The colored yarn here can be the original yarn obtained by adding the color masterbatch during the spinning process, or it can be a colored yarn prepared by dyeing the natural yarn, or it can be spun after dyeing the fiber Spinning into the color.

Preferably, when the knitted fabric of the present invention is washed with water droplets after 10 times of washing, the water absorption time is measured within 1 second, and the dynamic moisture transfer method index (MMT) is more than 24 points; and the knitted fabric passes 10 The residual moisture content after the second washing is within 10%. The higher the MMT index, the lower the residual moisture rate and the better the quick-drying property.

The present invention is further described below in conjunction with examples and comparative examples, but the scope of the invention is not limited thereto.

The test methods of the parameters related to the present invention are as follows:

(1) Whether the hydrophilic resin (or water repellent resin) is attached

Next, using a scanning electron microscope (SEM, manufactured by Shimadzu Corporation), the disassembled yarns were observed to determine whether resin was adhered on the surface. Then, the resin-attached yarn is further analyzed to determine the hydrophilicity of the resin. The details are as follows: 6-8 yarns are visually arranged side by side without gaps to form a yarn bundle, and a drop of water is dripped from a dropper 1 cm directly above. If the water can be completely absorbed within 60 seconds, it is regarded as this Hydrophilic resin is attached to the yarn; if the water cannot be completely absorbed within 60 seconds, it is considered that the water-repellent resin is attached to the yarn.

(2) Dynamic moisture transfer index (MMT)

Refer to GB/T21655.2-2009 for testing, and calculate according to the following formula. Dynamic moisture transfer index (MMT) = wetting time (level) + maximum wetting radius (level) + one-way transfer index (level) × 2.
