Description

Technical Field

[0001] The utility model relates to the technical field of textiles, and more specifically to a light-shielding and sun-proof knitted fabric. Background Art

[0002] Fabrics are the main materials for making clothes that people wear daily. Existing fabrics are divided into knitted fabrics and woven fabrics. Knitted fabrics usually have a soft touch and good breathability, so they are often used to make underwear, leggings and other close-fitting clothing.

[0003] However, compared with woven fabrics, knitted fabrics usually have a looser structure during weaving, which results in more pores in the knitted fabrics. The sunlight can directly penetrate the fabrics through these pores and shine on the skin, making it impossible for clothes made of knitted fabrics to effectively block the penetration of ultraviolet rays when worn. In the summer when the sun is strong, the skin is easily sunburned and the sun protection effect is poor.

[0004] Therefore, new solutions need to be proposed to solve this problem. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a light-shielding and sun-proof knitted fabric to solve the problem that clothing made of knitted fabric has a poor sun-proof effect.

[0007] The utility model is further configured as follows: the plurality of diverging grooves on both sides of the outer layer are of the same size and are symmetrically arranged along the width direction of the fabric, and the plurality of diverging grooves on both sides of the outer layer are integrally formed by weaving a ridge plaiting structure.

[0008] The utility model is further configured as follows: a plurality of the divergent yarns are symmetrically arranged along the width direction of the fabric, the divergent yarns are formed by alternately twisting the first strand and the second strand through "S" twisting and "Z" twisting, the first strand is formed by twisting flax fiber, and the second strand is formed by twisting acrylic fiber.

[0009] The utility model is further configured as follows: the divergent yarn is located at its "Z" twist position and the second strand is spirally wound on the first strand, and the plurality of divergent parts are integrally formed on the divergent yarn by twisting the second strand through the "Z" twist.

[0010] The utility model is further configured as follows: the plurality of depressions on both sides of the inner layer are staggered along the length direction of the fabric, and the plurality of depressions on both sides of the inner layer are formed by deforming after threading a plurality of divergent yarns.

[0011] The utility model is further configured as follows: the outer layer is woven by reflective yarn, the reflective yarn is made by twisting the first strand and the second strand in an "S" twist manner, the inner layer is made by weaving the shading yarn in a plain stitch manner, and the weaving density of the inner layer is twice that of the outer layer.

[0012] The utility model is further configured as follows: the shading yarn is made by spirally winding a second strand of yarn on a third strand of yarn, and the third strand of yarn is twisted by bamboo charcoal fibers.

[0022] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] Embodiment: The light-shielding sun-proof knitted fabric, such as Figure 1 , Figure 2 and Figure 6 As shown, it includes an inner layer 1 and an outer layer 2 fixedly connected to each other, and a plurality of long diverging grooves 3 are provided on both sides of the outer layer 2. The outer layer 2 is woven by feeding the reflective yarn 10 into a knitting machine through a ridge knitting structure. The plurality of diverging grooves 3 on both sides of the outer layer 2 are integrally formed by the ridge knitting structure. The plurality of diverging grooves 3 on both sides of the outer layer 2 are of the same size and symmetrically arranged along the width direction of the fabric, so that the two sides of the outer layer 2 are uneven and can reflect part of the sunlight. The reflective yarn 10 is made by twisting a first strand 8 and a second strand 9 by an "S" twisting method through a twisting machine. The first strand 8 is twisted by a twisting machine by twisting flax fiber, and the second strand 9 is twisted by twisting acrylic fiber. Acrylic fiber has good light resistance and can resist sunlight. The good gloss of acrylic fiber enables the outer layer 2 to reflect most of the sunlight. The surface of flax fiber is relatively rough, so it can weaken the intensity of sunlight by reflection, scattering, absorption, etc., thereby enhancing the reflection and scattering effect of the outer layer 2 on sunlight.

[0024] like Figure 1-Figure 4 As shown, the inner layer 1 has a number of divergent yarns 4 threaded through it along the length direction of the fabric, and the divergent yarns 4 are threaded through the inner layer 1 by a sewing needle. A number of arc-shaped depressions 5 are provided on both sides of the inner layer 1, and the several depressions 5 on both sides of the inner layer 1 are deformed after threading a number of divergent yarns 4, so that the several depressions 5 on both sides of the inner layer 1 are staggered along the length direction of the fabric. After the inner layer 1 and the outer layer 2 are sewn together by a sewing machine, a number of divergent spaces 6 are formed between the several depressions 5 on the side of the inner layer 1 close to the outer layer 2 and the several divergent grooves 3 on the side of the outer layer 2 close to the inner layer 1.

[0025] like Figure 1-Figure 5As shown, a plurality of divergent parts 7 are fixedly connected to the divergent yarn 4, and the plurality of divergent yarns 4 are symmetrically arranged on the inner layer 1 along the width direction of the fabric, and the distance between adjacent divergent parts 7 on the divergent yarn 4 is the same as the distance between adjacent recesses 5 on the side of the inner layer 1 close to the outer layer 2, so that the plurality of divergent parts 7 on the divergent yarn 4 are all located in the divergent space 6, and the divergent yarn 4 is formed by alternately twisting a first strand 8 and a second strand 9 by an "S" twist and a "Z" twist through a twisting machine, and the divergent yarn 4 is located at its "Z" twist. The second strand 9 is spirally wound around the first strand 8, and a plurality of divergent parts 7 are integrally formed on the divergent yarn 4 after the second strand 9 is tightly wound around the first strand 8 by a "Z" twist. The plurality of divergent spaces 6 and the cylindrical divergent parts 7 made of flax fiber and acrylic fiber located inside the divergent spaces 6 can diverge the sunlight entering the fabric, thereby reducing the intensity of the sunlight in the fabric. At the same time, the good moisture dissipation effect of flax fiber can timely disperse the moisture in the fabric, thereby preventing the fabric from sticking to the skin through sweat and causing discomfort.

[0026] like Figure 1 and Figure 7 As shown, the inner layer 1 is made by feeding the shading yarn 11 into a knitting machine and weaving it in a plain stitch manner. The shading yarn 11 is made by spirally winding a second strand 9 around a third strand 12 through a spindle spinning process. The third strand 12 is twisted by a bamboo charcoal fiber through a twisting machine. The bamboo charcoal fiber has good hygroscopicity while having a certain shading property, so that the made inner layer 1 can absorb the sweat generated on the wearer's body surface in time to keep the skin dry and comfortable. By tightly wrapping the acrylic fiber on the bamboo charcoal fiber, a shading and sunscreen layer is formed on the surface of the bamboo charcoal fiber. The weaving density of the inner layer 1 is twice that of the outer layer 2. The inner layer 1 made by increasing the weaving density of the inner layer 1 and the shading yarn 11 can effectively limit the penetration of light, avoid the sunlight in the fabric from penetrating the inner layer 1 and irradiating the skin, so that the fabric has a good shading and sunscreen effect.

[0027] 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.
