Description

AN ABSORBENT YARN AND AN ABSORBENT LAYER MADE OF THIS YARN

AND A TEXTILE PRODUCT COMPRISING THIS LAYER

Technical Field

The invention relates to a yarn that provides adsorption of liquids by diffusion and/or capillary absorption, to a reusable and washable absorbent fabric having a layer made of said yarn, and to textile products comprising said fabric.

State of the Art

Care and hygiene products are part of medical textiles. Sanitary pads, adult diapers, and baby/child diapers are the most well-known examples of care and hygiene products. These products are required to have high properties such as liquid absorption performance, comfort, and abrasion resistance.

Sanitary pads are the products with the largest market among the hygienic products produced from non-woven surfaces worldwide. They generally have a multi-layered structure. It is expected not to leak, not to cause bad odor, to have easy operation and improved comfort features.

Baby/child diapers are products that contain superab sorbent polymers that have the ability to quickly absorb and store liquid and are usually produced from fossil fuels. However, it is very important that they do not leak during use and do not cause infection by keeping the skin dry. Adult diapers are products designed for use by people with urinary and fecal incontinence.

These products can be designed for single or multiple uses. Disposable products are structures in which nonwoven surface textiles are combined with film-like structures to provide impermeable properties. Considering the economic disadvantages of disposable products and the environmental problems that arise during their destruction, their preferability decreases. In addition, disposable hygiene products impose a great burden on the environment. Inadequate comfort features of disposable products cause allergic reactions to the skin and create a feeling of discomfort in the user.

Reusable products, on the other hand, are generally multi-layered and can be reused after being washed and subjected to appropriate stabilization after use.

Patent documents numbered EP2938308B1, EP2938310B1 and EP2938309B1 relate to disposable absorbent products with absorbent properties and a separator fabric in order to provide liquid flow control.

The patent document numbered CN110742733A relates to a disposable diaper containing an elastic spacer fabric. The yarns forming the lower and upper layers of the spacer fabric and the yarns connecting these layers have different content and properties. The spacer yarns of the spacer fabric are made of absorbent fiber and enable the diaper to have absorbent properties.

The utility model document numbered CN209236603U discloses a three-dimensional fabric and a hygiene product containing it. Due to the three-dimensional fabric, the structure has air permeability and liquid absorbency.

A patent document numbered EP1330225B1 discloses a disposable hygiene product containing a spacer fabric as a liquid distribution layer.

A patent document numbered EP2542197B1 discloses a washable and reusable incontinence product with three-dimensional fabric in its structure.

The utility model document numbered DE29504038U discloses a washable diaper/adult diaper system with a spacer fabric in its structure.

A patent document numbered EP3863578B1 discloses an absorbent material containing spacer fabric that can be used in reusable and washable underwear products. It is seen that the disposable and reusable products in the state of the art are used to increase the absorbency of the spacer fabrics in three-dimensional form with the absorbent and upper layer connected to each other with the spacer yams and to control the fluid flow within the multilayer structure.

Although the use of these spacer fabrics, also known as three-dimensional fabrics, has become widespread in single and multi-use products, it is seen that they are still not at the desired point in terms of providing sufficient absorbency capacity.

As a result, all the above-mentioned problems have made it necessary to make an innovation in the related field.

Objects of the Invention

The main object of the invention is to increase the absorbency and liquid retention capacity of three-dimensional fabrics used in single- or multi-use hygiene products.

Another object of the invention is to increase the absorbency and liquid retention capacity, especially without experiencing a decrease in strength.

Another object of the invention is to provide a comfortable three-dimensional fabric to prevent allergic reactions on the skin, feeling of wetness and moisture, and to prevent the growth of pathogens and bacteria.

Brief Description of the Invention

The present invention comprises an absorbent layer, an upper layer with openings on its surface and the spacer yarns that connected said surfaces. In the said absorbent layer, the absorbent layer comprises a fiber having an hollow cross-section. The said hollow crosssection fiber increases the capacity of liquid absorption and liquid retention under pressure.

Although increasing the absorption and liquid retention capacity of hollow cross-section fibers is a positive feature, in general terms, the strength of the resulting structure decreases, especially when a viscose and similar fiber is selected. For this reason, the absorbent layer mentioned in an embodiment of the invention is made of two different fibers. The second fiber used herein is selected such that its strength, especially in the wet state, is higher than that of the primary fiber, for example, cotton fiber. Accordingly, the liquid absorption and retention functions are increased, and the strength is provided at the desired level.

Detailed Description of the Invention

The subject matter of the invention relates to a yarn that provides adsorption of liquids by diffusion and/or capillary absorption, to a reusable and washable absorbent layer fabric having a layer made of said yarn, and to textile products comprising said layer fabric.

The yarn of the invention can be used in any fabric where an absorbency function is needed.

The said yarn (11) comprises at least primary fibers (I l la). The said primary fiber (I l la) is specifically selected to have a hollow cross -section. The said hollow cross-section structure mentioned herein ensures that when the three-dimensional fabric (10) is wetted, the liquid is absorbed and does not easily diffuse out of the yam (111) under pressure.

Preferably, the said primary fiber (I l la) is made of synthetic fiber, natural fiber, regenerated fiber, or blends thereof.

Preferably, the said primary fiber (I l la) is synthetic fiber such as polyester, polyamide, or polyolefins; biodegradable synthetic fiber such as poly hydroxy alkanoate (PHA), polylactic acid (PLA), polycaprolactone; natural fiber such as cotton, organic cotton, linen, hemp, silk, bamboo, silk cotton, angora; regenerated fiber such as viscose, modal, acetate, lyocell or blends thereof, and is preferably viscose.

The cross-section of the primary fiber (I l la) may be circular hollow, triangular hollow, trilobal hollow, + hollow, W hollow, collapsed hollow, octalobal hollow. Preferably, collapsed hollow geometry is used. In addition, the cross-section of the primary fiber (I l la) may be symmetrical or asymmetrical.

Preferably, the primary fiber (I l la) may be of filament or staple structure, preferably staple structure. In a preferred embodiment of the invention, the absorbent layer (11) is made of a yarn (111) comprising primary fibers (I l la) as well as secondary fibers (111b), as can be seen in Figure 1. The said secondary fibers (111b) are used to address the strength problem posed by the primary fibers (Il la).

Preferably, the secondary fiber (111b) is made of synthetic fiber, biodegradable synthetic fiber, natural fiber regenerated fiber, or blends thereof.

Preferably, the secondary fiber (111b) is made of synthetic fiber such as polyester, polyamide, polyolefins; biodegradable synthetic fiber such as poly hydroxy alkanoate (PHA), polylactic acid (PLA), polycaprolactone; natural fiber such as cotton, organic cotton, linen, hemp, bamboo, silk, silk cotton; regenerated fiber such as viscose, modal, acetate, lyocell and/or blends thereof. In particular, the secondary fiber (111b) was used as organic cotton fiber. The secondary fiber (I l la) contained in the yarn is a natural fiber and has high absorbency. The yarn (3) made of the blend of the primary fiber (Il la) and the secondary fiber (111b) ensures that the absorbent layer (11) has a high liquid absorption performance.

In a preferred embodiment, the yarn (111) comprises a blend of l%-99%, preferably 30%- 70% primary fiber (I l la), and 99%-l%, preferably 70%-30% secondary fiber (111b).

Referring to Figure 2a, the thickness of the yarn (111) is in the range of 6/1 Ne-80/4 Ne, preferably in the range of 6/1 Ne-16/2 Ne. The yarn (111) may be used as a single- or multiply in the knitted structure and is preferably used as a multi-ply. The multi-ply use of the yarn (111) forming the absorbent layer (11) enables the fibers (I l la, 111b) forming the yarn (111) to exhibit optimum absorbency and liquid retention behaviors.

As mentioned, an absorbent layer (11) is made of the said yarn (111). This absorbent layer (11) is used in a three-dimensional fabric (10).

The three-dimensional fabric (10) of the invention consists of multiple layers and is arranged to provide absorbency in the area where it is used. The three-dimensional fabric (10) can be used on its own or with multiple layers to be connected to it. In addition, the three- dimensional fabric (10) can also be used by connecting to other textile products, especially hygiene products. For example, the said three-dimensional fabric (10) can also be used in diapers for children, and adults, or sanitary pads.

Referring to Figure 2, the said three-dimensional fabric (10) consists of three layers in its most basic form. Three-dimensional fabric (10) is also known as spacer fabric or sandwich fabric. These are the absorbent layer (11), the upper layer (12), and the spacer yarns (13) that connect said absorbent layer (11) and the upper layer (12), respectively. The said absorbent layer (11), the upper layer (12), and the spacer yams (13) are unified.

The absorbent layer (11) is the layer that allows the three-dimensional fabric (10) to exhibit absorbency. The absorbent layer is made of a yam (111) comprising the primary fibers (I l la) and preferably the secondary fibers (11 lb).

Referring to Figures 2 and 2b, the upper layer (12) is a structure with multiple openings (121). The said openings (121) basically allow the liquid to be absorbed and retention to reach the absorbent layer (11). Preferably, the absorbent layer (11) has a surface structure without openings (121) in the upper layer (12).

The said absorbent layer (11) and the upper layer (12) are connected to each other by spacer yarns (13). The said spacer yarns (13) extend between the facing surfaces of the absorbent layer (11) and the upper layer (12).

Accordingly, the said three-dimensional fabric (10) is characterized in that it comprises an absorbent layer (11) made of yarn (111) comprising hollow cross-section primary fibers (I l la), an upper layer (12) with multiple openings (121) provided therein, and spacer yarns (13) between the said absorbent layer (11) and the said upper layer (12) for connecting the said absorbent layer (11) and the said upper layer (12).

The upper layer (12) is preferably made of synthetic yarn such as polyester, polyamide, polyolefins; biodegradable synthetic yarn such as poly hydroxy alkanoate (PHA), polylactic acid (PLA), polycaprolactone; natural yarn such as cotton, organic cotton, linen, hemp, bamboo, silk, silk cotton; regenerated yarn such as viscose, lyocell, acetate, modal and/or blends thereof, and is especially made of polyester. The upper layer (12) may be in the form of a cross-section of the yarn or yarns forming; circular filled, circular hollow, triangular filled, triangular hollow, trilobal filled, trilobal hollow, + filled, + hollow, W filled, W hollow, collapsed filled, collapsed hollow, octalobal filled, octalobal hollow. It can also be symmetrical or asymmetrical. Preferably, it has a filled circular structure.

The yarns forming the three-dimensional fabric upper layer (12) may be in filament structures such as multifilament, monofilament, or staple structure and preferably in multifilament structure. The yam may consist of 100-1000 filaments and preferably 300-900 filaments. The thickness of the yarns forming the three-dimensional fabric upper layer (12) is in the range of 100 denier-800 denier and preferably in the range of 150 denier-450 denier. The yarn forming the upper layer (12) can be used as a single or multi-ply in the knitting structure and is preferably used as a multi-ply. It is aimed to increase the number of filaments of the yam with the use of multi-ply yarn. Increasing the number of filaments in the upper layer (12) by using multi-ply yarn ensures that the three-dimensional fabric (10) has a soft touch and attitude and increases user comfort.

Referring to Figure 2b; the openings (121) of the upper layer (12) may be of different shapes, such as circular, oval, diamond, square, rectangular, preferably oval. The width of the openings (121) is in the range of 0.5 mm-3 mm in the transverse direction and 0.5 mm-4 mm in the longitudinal direction. The upper layer (12) may have 5-7 openings (121) per cm2. Due to the oval-shaped openings (121) on the upper layer (12), the liquid is not retained in the upper layer (12) and is easily transmitted to the three-dimensional absorbent layer (11) with high absorbency. Due to the fact that liquid is not retained in the top layer (12), the user does not feel wet and uncomfortable.

Preferably, the spacer yarns (13) are located between the upper layer (12) and the absorbent layer (11) and connect the said layers.

The spacer yarns (13) may preferably be synthetic yarn such as polyester, polyamide, polyolefins; biodegradable synthetic yarn such as poly hydroxy alkanoate (PHA), polylactic acid (PLA), polycaprolactone; natural yarn such as cotton, organic cotton, bamboo, linen, hemp, silk, silk cotton; regenerated yam such as viscose, lyocell, acetate, modal and/or blends thereof, and may be especially made of polyester.

The intermediate layer (40) has a weight in the range of 50 g/m² to 700 g/m², preferably in the range of 200 g/m² to 400 g/m².

The intermediate layer (40) supports the absorbency performance of the three-dimensional fabric (10). The secondary outer layer (50) is the layer of the multilayer textile product (14) that contacts the user's skin and is positioned on the three-dimensional fabric (10).

The secondary outer layer (50) will prevent the solid content to be transferred to the three- dimensional fabric (10) from penetrating the three-dimensional fabric layer (10) and is disposable. After use, the secondary outer layer (50) is discarded, and the textile product is easily cleaned.

The secondary outer layer (50) is preferably a non-woven surface, preferably the woven, knitted, or non-woven surface may be a textile product. It can be produced by methods in the state of the art such as needle-punch, spun lace, spun bond, melt blown, and a non-woven surface produced by the spun lace method is preferably used in the invention.

The secondary outer layer (50) is preferably made of synthetic fiber such as polyester, polyamide, polyolefins; biodegradable synthetic fiber such as poly hydroxy alkanoate (PHA), polylactic acid (PLA), polycaprolactone; natural fiber such as cotton, organic cotton, linen, hemp, bamboo, silk, silk cotton; regenerated fiber such as viscose, lyocell, acetate, modal and/or blends thereof, and is especially made of polypropylene.

The secondary outer layer (50) has a weight in the range of 10 g/m² to 150 g/m², preferably 10 g/m² to 50 g/m².

The said three-dimensional fabric (10) can preferably be produced by weft knitting or warp knitting technology and is preferably produced by weft knitting. The three-dimensional fabric (10) preferably has a weight of 100-1200 g/m², preferably 300- 800 g/m². The three-dimensional fabric layer (10) preferably has a thickness in the range of 2mm-60mm, preferably in the range of 3mm-7mm.

The three-dimensional fabric (10) preferably has a compression rate under pressure in the range of 15%-50% and preferably in the range of 20%-40% according to the TS EN ISO 1856 standard. The compression rate of the three-dimensional fabric (10) under pressure should be at an optimum level. The high compression rate causes the liquid absorbency performance of the three-dimensional fabric (10) to be adversely affected. The low compression rate causes the three-dimensional fabric (10) to create a feeling of stiffness in the user.

The three-dimensional fabric (10) preferably ensures that the multilayer textile product has high liquid absorbency and liquid retention capacity. The three-dimensional fabric (10) has superior liquid absorption performance due to the upper layer (12) with oval-shaped openings (121) and the absorbent layer (11) made of yarn (111) consisting of different fiber blends. The liquid is absorbed from the upper layer (12) containing oval-shaped openings (121) and transmitted to the absorbent layer (11) containing yarn (111) made of a blend of collapsed hollow primary fiber (I l la) and highly absorbent secondary fiber (111b). The liquid is retained by the highly absorbent layer (11). Due to the fact that the liquid is transmitted from the three-dimensional fabric upper layer (12) to the absorbent layer (11) and no liquid is retained in the upper layer (12), there is no liquid contact with the user's skin and the user does not feel wet.

The fact that the upper layer (12) of the three-dimensional fabric (10) consists of high filament count yarns consisting of fine fibers reduces the feeling of wetness and increases the comfort feature of the structure. Due to the absorbent layer (11), it has a high liquid absorption capacity, and it is ensured that the liquid is kept in the structure under pressure. The spacer yarns (13) create a gap between the absorbent layer (11) and the upper layer (12), and thereby this gap, the structure has thermal comfort and rapid drying feature. Thus, comfortable hygiene products with superior liquid absorbency performance and liquid retention capacity can be obtained.
