Description

Technical Field

[0001] The utility model relates to the technical field of polyester fabrics, and more specifically, to anti-dyeing and high color fastness polyester fabrics. Background Art

[0002] Polyester fabric is a kind of chemical fiber clothing fabric used very much in daily life. Its biggest advantage is its good wrinkle resistance and shape retention. Therefore, it is suitable for making outerwear, various bags, tents and other outdoor products.

[0003] Polyester fabric has the advantages of good strength, smoothness and crispness, but has the disadvantage of low color fastness. In order to improve the color fastness of existing polyester fabrics, the dyeing process is usually changed, thereby starting with the process and ultimately improving the color fastness of polyester fabrics. The cost of improving the color fastness of polyester fabrics by process changes is relatively high, and the sun protection of polyester fabrics is poor. The pores of polyester fabrics increase after stretching, which further reduces their sun protection effect. Fabrics with high weaving density have poor air permeability, affecting wearing comfort.

[0021] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] The anti-dyeing high color fastness polyester fabric, such as Figure 1As shown, it includes a surface layer 1 and a base layer 2 which are fixedly connected to each other. The double-layer setting of the surface layer 1 and the base layer 2 increases the thickness of the fabric, improves the practical strength of the fabric and the sun protection effect. The warp and weft of the base layer 2 form an angle of 45 degrees with the warp and weft of the surface layer 1, so that the warp and weft of the base layer 2 are blocked by the woven pores of the surface layer 1, and at the same time, the warp and weft of the surface layer 1 are blocked by the woven pores of the base layer 2, further enhancing the shielding effect against sunlight, and the woven pores also facilitate the exchange of air on both sides of the fabric, thereby enhancing the breathability of the fabric. The fabric improves the wearing comfort while ensuring the sun protection effect.

[0023] like Figure 1 , Figure 2 and Figure 4 As shown, the base layer 2 is formed by alternately weaving yarn 1 3 and yarn 2 4, the diameter of yarn 1 3 is smaller than the diameter of yarn 2 4, and a concave groove 5 is formed at the intersection of yarn 1 3 in the warp direction and yarn 1 3 in the weft direction, and the concave groove 5 is connected with the weaving pores of the base layer 2, and yarn 1 3 is twisted by masterbatch polyester fiber, and yarn 1 3 and yarn 2 4 are both set to dark colors. Yarn 1 3 and yarn 2 4 made of masterbatch polyester yarn as raw materials are not easy to fade in subsequent use and dyeing process, which ensures the color fastness of the base layer 2, and the dark color is sensitive to light. The reflection effect is poor and the absorption effect is good, which hinders the reflection effect of light in the fabric and improves the sun protection of the base layer 2. The diameter of the yarn 3 is small, so the thickness of the base layer 2 at the recessed groove 5 formed during the weaving process is thinner, which is more convenient for air exchange and circulation. The recessed groove 5 array is arranged on the base layer 2, so that the surface of the base layer 2 on the side close to the body is uneven, reducing the contact area between the base layer 2 and the body surface, so that after the body surface sweats, the air circulates between the base layer 2 and the body surface, accelerating the evaporation rate of sweat and keeping the base layer 2 and the body surface dry and comfortable.

[0024] like Figure 4 As shown, yarn 2 4 is twisted by masterbatch shaped polyester fibers, and the cross-sectional shape of the masterbatch shaped polyester fibers is plum blossom-shaped. A plurality of grooves are formed on the peripheral wall of the plum blossom-shaped masterbatch shaped polyester fibers, so that the flow guiding effect of yarn 2 4 is better, and the diameter of yarn 2 4 is relatively large. When the base layer 2 contacts the body surface, the peripheral wall of yarn 2 4 contacts the body surface, and the sweat on the body surface is easily guided and transferred through yarn 2 4, thereby further accelerating the transfer and evaporation rate of sweat.

[0025] like Figure 1 and Figure 4As shown, a bulge is formed at the intersection of the yarn 24 in the warp direction and the yarn 24 in the weft direction, and a support point 6 is fixedly connected to the bulge on one side of the base layer 2. The support point 6 is set to a hemispherical shape, and the support point 6 is formed by point molding equipment. The support point 6 is set to a rubber material, and the side of the support point 6 away from the base layer 2 is in contact with the surface layer 1. The support point 6 supports the surface layer 1 and the base layer 2 to form a channel, which is convenient for the air to flow efficiently between the base layer 2 and the surface layer 1, and the support point 6 made of rubber material has elastic deformation ability. After the surface layer 1 is pressed, the support point 6 is deformed to cushion the impact on the surface layer 1 and improve the compression resistance of the fabric. The support point 6 is fixed on the base layer 2 by point molding, so that the connection between the support point 6 and the base layer 2 is more stable.

[0026] like Figure 1 , Figure 3 and Figure 5 As shown, the surface layer 1 is woven by alternating yarn three 7 and yarn four 8, the diameter of yarn three 7 is smaller than the diameter of yarn four 8, the cavity 9 on the side of the surface layer 1 away from the base layer 2 increases the roughness of the surface layer 1, and the diffuse reflection effect of light irradiated on the surface layer 1 is better, so people have less visual impact when wearing it, and it is softer and more comfortable to wear. The cavity 9 is formed at the intersection of the yarn three 7 in the warp direction and the yarn three 7 in the weft direction, and the cavity 9 is connected with the recessed groove 5. The cavity 9 is coated with a waterproof and breathable coating 10, which realizes the waterproof effect of the fabric and ensures the normal circulation of air. The cavity 9 is connected with the recessed groove 5 through a channel, and the woven pores of the surface layer 1 and the woven pores of the base layer 2 are connected in series to ensure the stable circulation and exchange of air.

[0027] like Figure 1 and Figure 5 As shown, the weaving density of the surface layer 1 is the same as the weaving density of the base layer 2, and the weaving density is equal, so that when the surface layer 1 is rotated 45 degrees and fixed on the base layer 2, it can stably cover the weaving pores of the base layer 2, thereby ensuring the sun protection effect of the fabric. The yarn three 7 and the yarn four 8 are both twisted by matte polyester yarn. The blank width of the surface layer 1 and the base layer 2 is greater than 200 cm. The matte polyester yarn has a lower light quality and is suitable for making clothing for wearing.

[0028] like Figure 4 As shown, the twisted yarn 1 3 and yarn 2 4 are alternately threaded and fixed on the air-jet loom, and during the weft beating process, yarn 1 3 and yarn 2 4 are also alternately woven to form a base layer 2. The support point 6 is fixed to the base layer 2 by point molding at the raised position of the base layer 2 to complete the processing of the base layer 2.

[0029] like Figure 4 and Figure 5As shown, the twisted yarn three 7 and yarn four 8 are alternately threaded and fixed on the air-jet loom, and the yarn three 7 and yarn four 8 are also alternately woven during the beating process to form a surface layer 1. The coating machine coats a waterproof and breathable coating 10 on one side of the surface layer 1, and finally places the side not coated with the waterproof and breathable coating 10 on the side of the base layer 2 provided with the support point 6, rotates the surface layer 145 degrees, and finally fixes the base layer 2 and the surface layer 1 to obtain the fabric.

[0030] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
