Description

Single-sided knitted fabric

Technical Field

The invention relates to a single-sided knitted fabric, in particular to a single-sided knitted fabric with water absorption and quick drying functions.

Background

Along with the continuous improvement of living standard, the requirement of people on wearing comfort is higher and higher, and the common water-absorbing quick-drying product can not meet the requirements of people. Particularly, a large amount of sweat is generated by a human body during sports, and if the sweat cannot be absorbed and discharged timely and completely, the sweat can cause the fabric to be wet and adhered to the skin, so that the discomfort is particularly serious.

At present, people also study the water absorption and quick drying performance of the fabric more frequently. For example, japanese patent laid-open No. 10-131000 discloses a double-sided knitted fabric having a concave-convex structure with a height difference of 0.2mm to 2mm in the back side, wherein the concave portions are formed of viscose filaments or polyester/viscose mixed filaments having a single-filament fineness of 1 denier to 5 denier, and the convex portions and the front side are formed of polyester filaments, which can reduce stuffiness and stickiness after perspiration. Japanese patent application laid-open No. 2011-. The fabric is a double-layer knitted fabric or woven fabric, the surface layer is formed by hydrophilic yarns, the inner layer is formed by hydrophilic yarns and hydrophobic yarns, the crimp rate of the hydrophilic yarns in the inner layer is more than 5% of that of the hydrophobic yarns, namely, the fabric is designed to be hydrophilic on the surface and hydrophobic on the inner part, and the purpose of quick drying is achieved. However, because the technologies adopt a double-layer design, the water-retaining space between yarns is large, and the sweat conduction channel is relatively long, so that the time required for water diffusion is prolonged, and the quick drying property is still to be further improved.

For another example, chinese patent document CN103668732A discloses a one-way moisture-conducting and quick-drying cotton/polyester composite knitted fabric, which is obtained by weaving a plain weave single-sided weave structure with cotton yarn as an inner layer material and "Y" type section ultra-fine denier polyester filament yarn as an outer layer material. Sweat on the body surface is guided to the outer layer and quickly evaporated by utilizing the poor moisture-conducting capacity of the yarns on the surface layer and the inner layer, so that the inner layer of the fabric is kept dry and comfortable. However, since the inner layer is made of cotton yarn with high water retention, the dryness of the skin surface is difficult to ensure, and the wearing comfort is poor.

Further, japanese patent No. 5596886 discloses a fabric comprising a fiber a having no water repellency and a fiber B having water repellency, wherein the weight ratio of the fiber a to the fiber B is 50: 50-87: in the range of 13, such a fabric has water absorbing properties, water repellency properties, and floating property on water at the same time, but no solution to the quick-drying property has been proposed in this document.

Disclosure of Invention

The invention aims to provide a single-sided knitted fabric which has excellent water absorption and quick drying properties and can keep the skin dry and smooth.

The knitted fabric is a single-side-weave weft knitting fabric and comprises a surface and an inner side, wherein the inner side is formed by alternately arranging hydrophobic yarns and hydrophilic yarns A at intervals along weft coils, and a hydrophobic part is arranged on the inner side.

The knitted fabric has the function of quickly absorbing sweat and guiding the sweat to the surface so as to quickly diffuse on the surface, and meanwhile, the knitted fabric can keep dry and comfortable feeling inside the knitted fabric constantly, and unpleasant feeling of sticking to the skin after sweating can not occur. Is particularly suitable for manufacturing T-shirts, sports wear and other clothes needing sweat treatment in summer.

Detailed Description

The knitted fabric is a weft knitting object with single-side texture, has obvious light and thin advantages compared with a double-side texture knitted fabric formed by yarns with the same fineness, and is more favorable for sports. On the other hand, the sweat guide channel of the single-sided tissue fabric is relatively short, the problem that sweat is retained after sweat absorption like the double-sided tissue fabric is solved, and the quick-drying property is better.

The knitted fabric comprises a surface and an inner surface, wherein the inner surface is formed by alternately arranging hydrophobic yarns and hydrophilic yarns A at intervals along weft loops, the hydrophobic yarns on the inner surface form a hydrophobic part, and the hydrophilic yarns form a hydrophilic part. The alternating arrangement of the weft-wise loops herein means that the hydrophilic yarn and the hydrophobic yarn 1 are arranged alternately with 1 therebetween. The molecular structure of the hydrophobic yarn is compact, water molecules are not easy to enter the fiber, moisture (sweat) on the skin is concentrated to the hydrophilic part and absorbed and conducted, the dryness inside the fabric is guaranteed, and the phenomenon that the fabric is adhered to the skin cannot occur even if the sweat amount is large. If the hydrophilic yarns are all arranged inside, although sweat can be absorbed, the absorbed sweat can wet the fibers, so that the fabric is adhered to the skin. On the contrary, if the hydrophobic yarns are all arranged inside, sweat is retained on the surface of the skin and cannot be led out in time, and the problem that the fabric is stuck to the skin is also caused.

The hydrophobic portion in the present invention refers to a portion having no function of absorbing moisture. The hydrophilic part refers to a part having a function of rapidly absorbing sweat generated from the human body and conducting to the surface.

It is preferable that sweat be absorbed by the hydrophilic yarn a on the back surface and then be rapidly transferred to the surface, and that the hydrophilic yarn B be used on the surface because sweat absorption conductivity and surface diffusion property are better and the drying rate of the hydrophilic portion on the back surface can be increased, compared to the case where a hydrophobic yarn is used on the surface.

The hydrophilic yarn in the present invention is a yarn in which 6 to 8 yarns are arranged side by side without any gap by eye to form a yarn bundle, and one drop of water is dripped from a position 1cm above the yarn bundle by a dropper, thereby completely absorbing water within 60 seconds. The hydrophobic yarn in the present invention means a yarn which has failed to completely absorb water within 60 seconds by the above method.

The hydrophilic yarn a (or the hydrophilic yarn B) is a yarn having hydrophilicity per se or a yarn having a hydrophilic resin adhered to the surface thereof, and the hydrophobic yarn is a yarn having hydrophobicity per se or a yarn having a water-repellent resin adhered to the surface thereof.

When the hydrophilic yarn a (or the hydrophilic yarn B) is a yarn having hydrophilicity, the fiber material may be one or more of cotton, viscose, polyamide (Ny), and the like.

When the hydrophilic yarn a (or the hydrophilic yarn B) is a yarn having a hydrophilic resin adhered to the surface thereof, the hydrophilic resin is obtained by appropriately crosslinking a monomer having a strong hydrophilic group, and is capable of absorbing water in an amount hundreds or thousands of times, and the type thereof is not particularly limited, and may be an aqueous polyurethane resin, an aqueous acrylic resin, an aqueous polyester resin, or the like. The fiber material of the yarn attached with the hydrophilic resin in the invention can be one or more of common Polyester (PET), polybutylene terephthalate (PBT), polytrimethylene terephthalate (PTT), cation modified polyester (CDP) and the like.

The fiber raw materials of the hydrophilic yarn A and the hydrophilic yarn B in the invention can be the same or different. Preferably, the hydrophilic yarn a and the hydrophilic yarn B are the same and both yarns have a hydrophilic resin adhered to the surface thereof.

When the hydrophobic yarn in the present invention is a yarn having a water-repellent resin attached to the surface thereof, the fiber material may have water-repellent properties, and the water-repellent resin may be one or more selected from the group consisting of paraffins, silicones, water-carbides, and fluorine. The fluorine-containing compound may be carbon 4, carbon 6, carbon 8, or the like.

When the hydrophobic yarn is a yarn with hydrophobicity, the fiber raw material can be one or more of PET, PBT, PTT, CDP, polypropylene (PP) and the like. Wherein the PP fiber comprises common unmodified PP fiber, dyeable PP fiber, colored PP fiber (color masterbatch coloring) and the like. The dyeable PP fiber is obtained by uniformly dispersing a dyeable polymer (polyester, polyamide, or the like) in a PP resin and extrusion spinning. The colored PP fiber is prepared by mixing color master batch and polypropylene resin according to a certain proportion and carrying out melt spinning. The PP fiber is a chemical fiber having the smallest density, particularly a fine denier PP fiber, and has super-hydrophobicity, low moisture regain, strong moisture permeability, and unique wicking effect, and it is not easily combined with a conventional hydrophilic chemical agent to become hydrophilic, that is, it does not affect its hydrophobicity even if hydrophilic resin processing is performed at the time of finishing, and thus it is preferable. These fiber materials may be used as they are, or they may be synthesized according to a technique known in the art.

The knitted fabric of the present invention is preferably a plated stitch or a laid stitch. Among them, plating stitch is preferable in view of dynamic moisture transfer method index performance, wearing smoothness and comfort of the fabric.

Considering that the dry feeling of the skin can be influenced if the area of the hydrophilic part on the inner surface of the fabric is too large; conversely, if the hydrophobic portion on the inside is dominant, there is a possibility that sweat is not 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 in a state without tension is in the range of 1: 1.0 to 4.0. More preferably, the area ratio of the two is 1: 1.0 to 2.0.

Preferably, the hydrophilic yarns are longer than the hydrophobic yarns on the inner side of the fabric of the present invention. Compared with the coil formed by hydrophobic yarns, the coil formed by the hydrophilic yarns is large and fluffy, and the hydrophilic part formed by the coil is close to the skin, so that the coil is more beneficial to absorbing sweat and releasing sweat during sweating. In the present invention, the hydrophilic yarn is more preferably 5% to 15% longer than the linear length of the hydrophobic yarn.

In the present invention, it is preferable that the ratio of the fineness of each filament between the hydrophilic yarn B on the surface and the hydrophilic yarn a on the back surface is 1: 1.1 to 4.0. More preferably, the ratio of the fineness of the single yarn between the hydrophilic yarn B on the surface and the hydrophilic yarn a on the inner surface is 1: 2.0 to 3.5. Since the filament number of the surface yarn is smaller than that of the inner yarn, the filament gaps (capillaries) of the surface yarn relative to the inner yarn are denser, the capillary wicking effect is more obvious, and therefore the sweat inside can be better conducted to the surface and rapidly diffused. The finer the fineness of the surface yarn, the smaller the gaps (capillaries) between the monofilaments, and the better the water absorption effect.

In the present invention, the hydrophilic yarn B on the surface is preferably a multifilament of 50 to 150 denier (abbreviated as D) filaments or 30 to 80 count (abbreviated as D)^S) The spun yarn of (4). When filament multifilament of less than 50 denier is selected or the ratio is 80^SFine spun yarnIf the inner yarn is thicker than the outer yarn, poor knitting such as yarn reversing may occur, and the layering of the surface and the inner becomes unclear, and the feeling of dryness and smoothness of the skin surface tends to decrease; if the inner yarn is a yarn finer than the outer yarn, although the problem of the reverse yarn does not occur, there is a possibility that the outer fabric may be wet through and adhered to the skin because the outer fabric is thin. When selecting filament multifilament yarn with more than 150D or ratio of 30^SIn the case of thick spun staple yarn, if the inner yarn is a yarn having a thickness almost the same as that of the surface yarn, the layering of the surface layer and the inner layer becomes unclear and the feeling of dryness of the skin tends to decrease; furthermore, the obtained fabric is thick and has limited application. If the inner yarn is a finer yarn than the outer yarn, the structure of the inner layer is not obvious, sweat treatment of the skin surface may not be achieved, and dryness may be affected.

The knitted fabric can be obtained by weaving colored yarns or dyeing grey cloth. The colored yarn may be a spun yarn obtained by adding a color master batch during spinning, a colored yarn obtained by dyeing a natural colored yarn, or a colored yarn obtained by spinning after dyeing a fiber.

Preferably, when water drops are dripped into the knitted fabric after 10 times of washing, the water absorption time of the knitted fabric is measured to be within 1 second, and the dynamic moisture transfer method index (MMT) is measured to be more than 24 points; and the residual moisture content of the knitted fabric after being washed for 10 times is within 10 percent. The higher the MMT index, the lower the residual moisture content and the better the quick drying.

The present invention will be further described with reference to examples and comparative examples, but the scope of the present invention is not limited thereto.

The parameter testing method comprises the following steps:

(1) presence or absence of adhesion of hydrophilic resin (or water-repellent resin)

1 sample cloth of 10cm multiplied by 10cm is cut at any part of the fabric, one part of the yarn is unraveled, and the surface yarn and the inner yarn are marked according to the difference of the texture. Then, each of the split yarns was observed by a scanning electron microscope (SEM, manufactured by shimadzu corporation, japan) to determine whether or not the resin was adhered to the surface thereof. The yarn with the resin adhered thereon was further analyzed to determine the hydrophilicity of the resin. The method comprises the following specific steps: forming a bundle of 6 to 8 yarns which were arranged side by side without any gap by visual observation, dropping a drop of water from a position 1cm above the bundle by a dropper, and if water can be completely absorbed within 60 seconds, it is considered that hydrophilic resin is attached to the yarns; if water cannot be completely absorbed within 60 seconds, it is considered that a water-repellent resin is attached to these yarns.
