Detailed Description

The utility model provides a fabric with an air layer cut at will, and in order to make the purpose, technical scheme and effect of the utility model clearer and clearer, the utility model is further described in detail below by referring to the attached drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

The utility model provides a fabric with an air layer cut at will, which comprises a cloth cover 1, a cloth bottom 2 and an intermediate layer 3 arranged on the cloth cover 1 and the cloth bottom 2, wherein the cloth cover 1 and the cloth bottom 2 are hooked through the intermediate layer 3, the cloth cover 1 and the cloth bottom 2 are both staple fiber yarn layers woven by staple fiber yarns, the intermediate layer 3 is a filament yarn layer woven by filament yarns, the filament yarns are chemical fiber filament yarns with multiple F numbers, and the chemical fiber filament with multiple F numbers can be chemical fiber filaments with 24F numbers, 36F numbers, 48F numbers and 144F numbers; still be equipped with elastic layer 4 between cloth end 2 and the intermediate level 3 and between cloth cover 1 and the intermediate level 3, elastic layer 4 adopts the spandex yarn to weave the spandex layer that forms, and, the spandex layer forms the cobweb structure through special high temperature embryo decides technology between cloth cover 1, cloth end 2 and intermediate level 3.

Specifically, in the fabric with the structure, the fabric surface 1 and the fabric bottom 2 are both short fiber yarn layers woven by short fiber yarns, and the short fibers comprise pure spinning yarns of cotton, wool, silk, acrylic fibers and regenerated cellulose fibers or blended yarns of two or more of the pure spinning yarns. The short fiber yarns can form a non-flowing air layer on the surfaces of the cloth bottom and the cloth cover, and the air layer has a good warm-keeping effect, so that the fabric can be used as a warm-keeping underwear surface.

Preferably, the short fiber yarn is made of cotton, so that the fabric is skin-friendly and comfortable, and has good moisture absorption and vapor permeation effects.

It should be noted that the staple fiber yarns of the cloth bottom 2 and the cloth cover 1 may be the same or different, for example, the cloth bottom 2 and the cloth cover 1 both use cotton staple fiber yarns, or the cloth bottom 2 uses cotton, and the cloth cover 1 uses one of wool or silk, acrylic fiber, and regenerated cellulose fiber. The short fiber yarns of the cloth bottom 2 and the cloth cover 1 can be pure spun yarns or blended yarns, and can be combined randomly according to actual requirements.

More preferably, after the cloth bottom 2 and the cloth cover 1 are subjected to the hair grabbing treatment, a thicker non-flowing air layer can be formed on the surfaces of the cloth bottom 2 and the cloth cover 1, so that a better warm-keeping effect is achieved.

In the fabric with the structure, the middle layer 3 is hooked with the fabric bottom 2 and the fabric surface 1, and the fabric has the function of connecting and supporting. The middle layer 3 is made of filament yarns which are stiffer than staple fiber yarns, so that the fiber-reinforced polypropylene composite material has better stiffness and smoothness and can play a role in supporting a framework. Furthermore, the filament yarns adopt the chemical fiber filament yarns with multiple F numbers, the chemical fiber filament yarns with multiple F numbers can form a non-flowing air layer in the middle of the fabric, so that the heat preservation effect of the product can be greatly improved, and the initial modulus of the chemical fiber filament yarns with multiple F numbers is smaller than that of the chemical fiber filament yarns with single F numbers, so that the fabric is softer, the bottom penetration and the thread hooking are not easy to occur, the phenomenon of meat pricking cannot occur after edge cutting, and the skin-friendly effect is better.

Specifically, the chemical fiber filament is one of nylon or polyester filament. Because the single-filament yarn is the multi-F-number nylon filament yarn or the polyester filament yarn, the defects that the original single-filament air layer is easy to have chicken scratches and dead marks can be improved; meanwhile, compared with the monofilament, the nylon filament or the polyester filament with multiple F numbers can form more water passing channels, so that the nylon filament or the polyester filament has better moisture and vapor conducting effects. And the nylon filament or the polyester filament with multiple F numbers can form more relatively independent air layers, and has better heat preservation property.

Preferably, in the preparation process of the multi-F-number chemical fiber filament yarn, the yarn steaming and setting temperature is higher than the glass transition temperature of the chemical fiber filament, so that the stiffness of the filament is better, and the middle layer 3 made of the filament has a better skeleton supporting effect.

Preferably, in the fabric, the spandex is a hot-melt spandex, the hot-melt spandex can be melted at a specific temperature, and the hot-melt spandex is wrapped between the staple fibers and the filaments, so that when a blank fabric is formed, the hot-melt spandex is melted at a certain high temperature and is bonded with the staple fibers and the filaments to form the cobweb-shaped elastic layer 4, and further, the fabric has excellent resilience, and more importantly, the elastic layer 4 is cobweb-shaped and is not bonded with a certain yarn by the spandex alone, so that any staple fiber or filament is still bonded by the cobweb-shaped elastic layer 4 no matter the any staple fiber or filament is broken, and therefore, the phenomena of yarn hooking, looping and mouth scattering cannot occur, and the fabric has an arbitrary cutting effect. When the fabric is used, the fabric can be cut at will without sewing edges, so that on one hand, the manufacturing cost (materials and time) can be greatly saved, on the other hand, the fabric has better comfort, can be used as sports wear or underwear materials, and has a wider application range.

Preferably, in some embodiments, the yarn count of the short fiber is larger than that of the filament, that is, the yarn count of the cloth bottom 2 and the cloth cover 1 is larger than that of the middle layer 3, so that the short fiber yarn at the cloth bottom 2 and the cloth cover 1 can wrap the filament with a larger initial modulus, and meanwhile, the moisture absorption, the vapor permeability and the softness of the short fiber at the cloth bottom 2 and the cloth cover 1 are better, so that the fabric is more skin-friendly and comfortable to the skin, and static electricity cannot be generated. Typically, the filament yarns have a D number between 20D and 75D, while the staple fibers have a higher yarn count than the filaments. It should be noted that, because the yarn count of the staple fiber yarn is thicker than that of the filament yarn, a special yarn guide nozzle is needed in the preparation process to ensure the tightness of the cloth cover 1 and the cloth bottom 2 and avoid white exposure.

The air layer fabric with the structure can be cut at will through setting different yarn counts, yarn lengths, filament D numbers, spandex thicknesses and draft ratios, so that different performance changes can be achieved, and the air layer fabric with different functions can be cut at will.

The heat transfer performance of the textile of examples 1-5 and comparative examples 1-3 is tested by a flat plate method according to a GB/T35762-2017 textile heat transfer performance test method, and whether the fabric has the effect of four-side elasticity or random cutting is detected, wherein the test results are shown in Table 1.

TABLE 1 test results of heat transfer performance and effect of arbitrary cutting of air layer arbitrary cut fabric

As can be seen from Table 1, the air layer cut-free fabrics described in examples 1 to 5 all had the effect of four-sided projectile and cut-free, while comparative example 1 did not have the effect of four-sided projectile and cut-free and the meat-prick phenomenon occurred after cutting because the projectile wire used in the middle layer of comparative example 1 was easily protruded from the selvage after cutting and was easily pricked, while examples 1 to 5 used filament yarns having a large F number, and the meat-prick phenomenon did not occur even when cutting was performed. While comparative examples 2 and 3 have a four-side stretch effect but do not have a cutting effect, because the cobweb-shaped elastic layer can be formed only by using hot-melt spandex and passing a high embryo temperature, while comparative example 2 uses ordinary spandex, and the embryo temperature of comparative example 3 is lower than the melting temperature of the hot-melt spandex, so the cobweb-shaped spandex layer cannot be formed and the cutting effect is not achieved.

As can be seen from the heat transfer performance test results in table 1, the examples 1 to 5 all have better thermal resistance and better heat preservation effect, mainly because the multi-F number filament yarn can form a nonflowing air layer in the middle of the greige cloth, and simultaneously combine with the air layers of the cloth cover 1 and the cloth bottom 2, so that the heat preservation effect is better. In contrast, in comparative example 1, the filament yarn having a single F number is used as the intermediate layer 3, and the yarn having a single F number cannot form a nonflowing air layer, so that the heat retention effect is only dependent on the air layers of the cloth cover 1 and the cloth bottom 2, and the heat retention effect is inferior to that in examples 1 to 5.

In conclusion, the fabric with the air layer cut at will has the characteristics of small initial modulus and capability of forming the non-flowing air layer by adopting the filament yarns with multiple F numbers as the middle layer, so that the phenomena of root return and meat pricking are avoided during cutting, the comfortableness is good, and the formed non-flowing air layer can greatly improve the heat preservation effect of the fabric. The cobweb-shaped spandex coated on the cloth cover and the cloth bottom enables the fabric to have a better four-side elastic resilience effect and a random cutting effect, so that the fabric with the air layer warm-keeping effect has the characteristics of four-side elasticity and random cutting, can be used for manufacturing warm-keeping underwear and sports wear, and has a wide application range.

It should be understood that the technical solutions and the inventive concepts according to the present invention may be equally replaced or changed by those skilled in the art, and all such changes or substitutions should fall within the protection scope of the appended claims.
