Description

Technical Field

[0001] The invention relates to the technical field of textile fabrics, in particular to a heat-shielding and anti-see-through fabric. Background Art

[0002] Skin clothing is a kind of outerwear that is very suitable for wearing during exercise. Skin clothing has good air permeability, certain windproofness, water resistance, and is very soft, just like a thin layer of skin on the body, so it is called skin clothing. Skin clothing is also called skin windbreaker. The main function of skin clothing is to block ultraviolet rays, moisture-proof and breathable, windproof and close-fitting. It has a good protective effect on outdoor travel in summer and autumn, and is a functional clothing.

[0003] With the popularity of outdoor sports and the improvement of people's living standards, consumers have an increasing demand for outdoor functional clothing and higher requirements. Although skin clothing has the advantages of blocking ultraviolet rays, moisture-proof and breathable, windproof and close-fitting, it has poor elasticity. Elastic fabrics are widely used in the sports field because they can provide an unrestrained sense of movement. Low-denier (Denier number less than 30D) elastic fabrics are widely popular among consumers because of their light and comfortable characteristics. However, due to the thinness of the fabric, it is relatively easy to be seen through.

[0004] Titanium dioxide (TiO2) as an additive in textile slurry can improve the optical properties, antibacterial properties, antifouling properties and permeability of textiles, as well as weather resistance and durability, meet the functional requirements of textiles with different needs, increase the use value of textiles, and promote the development of the textile industry. In textile slurry, the amount of titanium dioxide added is generally 1%-5% of the total amount of textile slurry, and the specific amount added should be determined according to the requirements and functions of the textiles. However, the higher the titanium dioxide content, the rougher the yarn surface. When it is used as a warp yarn, it is easy to rub against the same part of the reed during the weaving process, causing wear of the reed, and at the same time leading to yarn breakage and abnormal production of grey cloth.

[0005] In view of this, the present invention provides a heat-shielding and anti-see-through fabric to solve the problem that the current low-denier elastic fabric is easily see-through. Summary of the invention

[0006] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an anti-see-through heat-shielding low-denier fabric.

[0007] In order to achieve the above object, the technical solution adopted by the present invention is:

[0008] A heat-shielding and anti-see-through fabric comprises a fabric main body layer, which is woven by interlacing warp yarns and weft yarns, wherein the warp yarns and weft yarns each comprise a surface layer, a middle layer and an inner layer, wherein the surface layer and the middle layer are made of a sheath-core yarn composed of two types of matt nylons, the inner layer is a spandex elastic yarn, the two types of matt nylons of the sheath-core yarn are respectively composed of nylon A1 and nylon A2, wherein the TiO2 content of nylon A1 is 1.5%-3.0%, the TiO2 content of nylon A2 is 10%-11%, the ratio of A1:A2 is 6:1-8:1,

[0009] Furthermore, in the core-sheath yarns of the warp yarns and the weft yarns, nylon A1 and nylon A2 are both nylon 6, or nylon A1 and nylon A2 are both nylon 66.

[0010] Furthermore, the denier numbers of the surface layer and the middle layer of the warp yarn and the weft yarn are less than 30D, and the spandex elastic yarn of the inner layer is 10D / 1F-20D / 1F.

[0011] Furthermore, the surface layer and the middle layer of the core-sheath yarn are wrapped together with the spandex elastic yarn of the inner layer by machine-wrapped twisting.

[0012] Furthermore, the twist of the core-sheath yarn and the spandex elastic yarn is 900-1100 twists.

[0013] Furthermore, the warp yarns and weft yarns are woven in any one of plain, twill, lattice and jacquard weaves.

[0014] Furthermore, the density of the warp yarn is 240T-285T, and the density of the weft yarn is 140T-200T.

[0015] Furthermore, a functional film layer is also provided on the surface of the fabric main body layer.

[0016] Furthermore, the functional film layer is a polyaliphatic compound film or a hydrophilic compound film.

[0017] After adopting the above scheme, the heat-shielding and anti-see-through fabric of the present invention not only ensures the matteness and hand feel of the fabric as a whole, but also overcomes the problem that the high TiO2 content easily causes friction with the steel reed during the weaving process, resulting in abnormalities such as broken yarn or dryness, by using the matte effect of a high proportion of TiO2. Since TiO2 has good stability and a high refractive index, when sunlight irradiates the fabric, most of the sunlight can be refracted and reflected off the surface of the fabric, greatly reducing the energy gathered on the surface of the fabric, thereby achieving a heat-shielding effect. Then, it is further matched with a reasonable fabric organization and density to make it a multifunctional low-denier four-sided stretch fabric. On the basis of the existing skin clothing functions, the present invention also has the functions of anti-see-through, heat-shielding and elasticity. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to further explain the technical solution of the present invention, the present invention is described in detail below through specific embodiments.

[0023] like Figure 1 As shown, the present invention discloses a heat-shielding and anti-see-through fabric, which includes a functional film layer 10 and a fabric main body layer 20 , wherein the functional film layer 10 is disposed on the fabric main body layer 20 .

[0024] The functional film layer 10 may be made of polyaliphatic compounds to repel water, or may be made of hydrophilic compound films such as polysiloxane compounds to absorb moisture. The functional high film layer 10 may be made of corresponding compound films according to actual functional requirements.

[0025] like Figure 2 and Figure 3As shown, the fabric main body layer 20 is formed by interlacing warp yarns 1 and weft yarns 2, the warp yarns 1 and weft yarns 2 are the same yarns, and both include surface layers 11, 21, middle layers 12, 22, and inner layers 13, 23. The surface layers 11, 21 and the middle layers are made of sheath-core yarns composed of two types of matte nylon 6 or nylon 66, the denier numbers of the surface layers 11, 21 and the inner layers 12, 22 are less than 30D, and the inner layer is 10D / 1F-20D / 1F spandex elastic yarn.

[0026] The sheath-core yarn composed of the surface layer 11, 21 and the middle layer 12, 22 is wrapped with the spandex elastic yarn of the inner layer by machine-wrapped twisting. This method is selected because the spandex elastic yarn accounts for a relatively high proportion, and the machine-wrapped twisting method can better wrap the spandex tightly. If the empty-wrapped method is selected, whitening abnormalities will easily occur. The twisting twist is 900-1100 twists.

[0027] The two types of matte nylons of the core-sheath yarn are composed of nylon A1 and nylon A2, respectively, wherein the TiO2 content of A1 is 1.5%-3.0%, the TiO2 content of A2 is 10%-11%, and the A1:A2 ratio is 6:1-8:1. The purpose of designing the TiO2 content of A1 to be 1.5%-3.0% is to maintain the feel and matte effect of the overall fabric surface, and if the content is too high, it is easy to cause friction with the reed during the weaving process, and it is easy to cause abnormalities such as broken yarn or dryness. The TiO2 content of A2 is designed to be 10%-11% because within this range, the fiber will not be too rigid and easy to break due to the excessively high TiO2 content, and the high TiO2 content can utilize the fog effect of TiO2 to achieve an anti-see-through effect. And because the core-sheath yarn has a high content of TiO2, TiO2 is a metal oxide, which can reflect a large amount of ultraviolet rays in sunlight, so it has excellent anti-ultraviolet function. Because TiO2 has good stability and high refractive index, when sunlight shines on the fabric, most of the sunlight can be refracted and reflected off the surface of the fabric, greatly reducing the energy gathered on the surface of the fabric, thereby achieving a heat-shielding effect.

[0028] In the present invention, the weave of the warp yarn 1 and the weft yarn 2 can be any one of plain weave, twill weave, lattice weave, jacquard weave, etc. The density of the warp yarn 1 is 240T-285T, and the density of the weft yarn 2 is 140T-200T.

[0029] The heat-shielding and anti-see-through fabric of the present invention has two kinds of nylon specific gravity and TiO2 content in the surface layer and middle layer structure of the core-skin yarn, i.e., the warp yarn 1 and the weft yarn 2, to ensure the overall matteness and hand feel of the fabric, and overcome the problems of easy friction with the steel reed during the weaving process due to the high TiO2 content, resulting in yarn breakage or yarn dryness, and at the same time, the matte effect of high proportion of TiO2 is used to achieve the anti-see-through effect and anti-ultraviolet effect. Then, with reasonable fabric organization and density, it becomes a multifunctional low-denier four-sided stretch fabric.

[0030] like Figure 4 As shown, the heat-shielding and anti-see-through fabric of the present invention has a more obvious anti-see-through effect than other low-denier anti-see-through fabrics.

[0031] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present invention.
