Description

A 3 layer structure high moisture transferable textile sheet

The present invention relates to a high water-transition fiber sheet having a three-layer structure consisting of a water absorption layer (1: back layer), a water transition layer (2: interlayer), and a water diffusion layer (3: surface layer). (2), the surface water layer 3 is characterized in that the process water content is increased, the specific surface area of the yarn is relatively wider and the density is more dense.

In Japanese Unexamined Patent Application Publication No. 3-213546 (1991.09.18), technical details regarding an absorbent sheet composed of a fiber structure having a high density portion and a low portion are proposed. The above technique uses the characteristic that moisture is moved from the low density layer to the high density layer using only the variation of density, but the low density layer is composed of hydrophilic material having a higher process moisture content than the high density layer. Have

On the other hand, Korean Patent Publication No. 2002-12828 (published on Feb. 20, 2002) discloses technical details regarding a double-woven circular knitted fabric composed of a backing layer composed of polyolefin twisted yarn and a surface layer composed of a polyester release cross-section yarn, but the surface layer is a polyester filament ( It is composed of filament yarns, which causes pilling when used for a long time. The filament yarn is a long fiber, which is stronger than the spun yarn made by spinning short fibers, but has a disadvantage in that a lot of lint is generated when it is used for a long time, and it does not produce a natural appearance due to its high gloss.

In addition, the patented technology of `` Absorption quick-drying fiber sheet having a three-layer structure, '' (2003-0059708, 2003. 08. 27) proposed by the inventor of the present invention consists of a polyolefin yarn in the water absorption layer (1) and a water transition layer (2). It is composed of a polyester release cross-section yarn and the water diffusion layer (3) is a fiber sheet composed of a polyester release cross-section yarn containing a hydroxyl group (-OH) as the invention gradually increases in density and density from the water absorption layer (1) to the water diffusion layer (3) In order to promote the fluidity of the water by increasing the process moisture content and specific surface area. However, since the water diffusion layer 3, that is, the surface layer is composed of a filament yarn of a heteromorphic cross-section structure, tearing is severe and pilling occurs during long-term use, and it is difficult to apply to non-sports clothing because of its high gloss.

Therefore, the technical problem to be achieved by the present invention is devised to improve the shortcomings of the conventional absorbent quick-drying material, which does not cause pilling even after long use, and its appearance is similar to that of natural materials, and its use is wide for general clothing.

The present invention is to remove the chemical fiber of the conventional absorbent quick-drying material to maintain the appearance of the natural material and at the same time to provide excellent anti-pilling properties (drying), absorption function.

In order to achieve the above object, the present invention provides a structure of a fiber sheet in which a water absorption layer, a water transition layer, and a water diffusion layer are sequentially stacked from the skin surface, and the water absorption layer is composed of a polyolefin filament yarn having a circular cross-sectional structure, and a water transition. The layer 2 is composed of polyester or polyamide cross-section filament yarns, and the water diffusion layer 3 provides a high moisture-displacement fibrous sheet having a three-layer structure composed of a single yarn or mixed with a polyester release cross-section filament yarn. . In addition, the present invention is the spun yarn natural fibers such as cotton, rayon; T / C (65% polyester, 35% cotton) mixed with cotton, rayon fiber and polyester or polyamide staple fiber material, T / R (65% polyester, 35% rayon), N / C (65% polyamide, 35% cotton) spun yarn; And at least one fiber sheet selected from the group consisting of polyester release yarns or polyamide release yarns. The present invention also provides a fiber sheet designed to have a density (all / inch) of 1.1 to 3 times more densely toward the water absorbing layer (1), the water transition layer (2), and the water diffusion layer (3). The present invention also provides a fibrous sheet in which the release cross-section filament yarns arranged alternately with the yarns in the water diffusion layer 3 when the water transition layer 2 is composed of the polyamide release cross-section yarns are polyamide release cross-section filament yarns. The fibrous sheet has a triple weave structure composed of a water absorbing layer (1: back layer), a water transition layer (2: interlayer), and a water diffusion layer (3: surface layer).

The sweat generated in the human body is first generated by the void capillary phenomenon in the micropores present in the water absorbing layer (1), followed by the vertical capillary phenomenon caused by the release cross-section filament yarn present in the water transition layer (2), and finally the surface layer. Diffuse cross-section filament yarn and spun yarn present in (3) are widely spread on the surface and finally dried quickly by a system where water evaporates into the atmospheric layer. Typically, moisture is a hydrophobic layer with a low process moisture content, a hydrophilic layer with a high process moisture content, a back layer because it has a property of easily moving from a low surface specific layer to a wide layer, and a low density layer with a dense layer. It is preferable to comprise a hydrophilic yarn, a higher density, and a larger specific surface area than the lower layer toward the interlayer (2) and the superficial layer (3) than the interlayer (2). By the preferred embodiment of the present invention will be described in detail. First of all, it should be noted that in the drawings, the same components or parts denote the same reference numerals as much as possible. In describing the present invention, detailed descriptions of related well-known functions or configurations are omitted in order not to obscure the subject matter of the present invention.

First, the water absorption layer (1: back layer) is composed of polyolefin filament yarn such as polyethylene having a circular cross-sectional structure. The yarn is a very hydrophobic material having a process moisture content (water content of fibers in a standard state) of 0.05% and contains no moisture, and thus has excellent drying properties. However, since there is a disadvantage in that there is no absorption function, it should be composed of a circular cross-sectional filament yarn having a relatively smaller cross-sectional area of yarn than a moisture transfer layer (2: interlayer) and a moisture drying layer (3: surface layer). In the case of the same fine yarn, the specific surface area of the circular cross-sectional structure is 20% smaller than that of the non-cross-sectional structure, and the specific surface area of the filament yarn is 30% smaller than that of the spun yarn. As a result, the specific surface area of the yarn of the water absorbing layer (1: back layer) is smaller than that of the water transition layer (2: interlayer) and the water drying layer (3: surface layer). This increases the fluidity of the moisture. In addition, the layer is designed to have a low density compared to the water transition layer (2: interlayer) to have a property of discharging without containing water, so that it has an absorption function despite the properties of hydrophobic yarns.

The water transfer layer (2: interlayer) is composed of a polyester release cross section filament yarn or a polyamide release cross section filament yarn. However, in the case where the water transfer layer (2: interlayer) is a polyamide release cross-section yarn, the release cross-section filament yarn used alternately with the yarn in the water diffusion layer (3: surface layer) should also be made of polyamide yarn.

A heteromorphic cross section yarn is a conventional circular cross-sectional structure that transforms a general yarn into a clover cross section, a triangular cross section, a double cross section, and so on, creating a capillary phenomenon in the groove of the yarn. In order to improve the function, cotton fiber containing hydroxyl group (-OH) has a chemical hydrophilic function, but has a physical hydrophilic function by capillary action. Polyester or polyamide filament yarn, which is a sectional cross-section yarn constituting the water transition layer (2: interlayer), has a higher process moisture content than the water absorption layer (1: back layer), so that moisture is transferred from the water absorption layer (1) to the water diffusion layer (3). Easy to transition Vertical capillary action occurs in this layer.

The density of the water transition layer 2 is designed to be 1.1 to 3 times (all / inch) more densely than the density of the water absorption layer 1. If the difference in density is less than 1.1 times, the fluidity of the water is lowered, and if it exceeds 3 times, the productivity is lowered.

The water diffusion layer (3) is used by using the yarn alone (4) or alternately mixed with the release cross-section yarn (5). Cotton or rayon, which is a natural material with a process water content of 8% or more, is suitable for spinning yarns. T / C (65% polyester, 35 cotton) that is spun by mixing polyester and polyamide staple fibers %), T / R (65% polyester, 35% rayon), N / C (65% nylon, 35% cotton) polyester spun yarn or polyamide made of staple fibers of spun yarn It is preferable to use a release spun yarn. A spun yarn is a long fiber made by spinning short fibers of 1 to 2 mm in size and has a large specific surface area and bulky properties.

The water diffusion layer 3 should be designed 1.1 to 3 times more densely than the water transition layer 2 to improve the fluidity of the water. In addition, when polyamide release cross-section filament yarn is used for the water transition layer (2), release cross-section filament yarns alternately used with yarns in the water diffusion layer (3) should use polyamide release cross-section filament yarns having the same process moisture content.

The fiber sheet of the present invention is effectively absorbed sweat due to the high specific surface area, density and process water content of the yarn as the water absorption layer (1), the water transition layer (2), and the water diffusion layer (3). ), The surface layer is composed of a spun yarn or mixed with a single-sided filament yarn, so that no tearing or peeling occurs and the appearance is similar to that of a natural material.

The fibrous sheet of the present invention can be woven in a loom capable of selectively supplying weft yarns, and can also be made into knitted fabric by knitting in circular knitting machines and tricot knitting machines.

The anti-pilling property, water absorption function and drying function, and water transfer rate of the fibrous sheet according to the present invention were evaluated by the following method.
