Description

Technical Field

[0001] This utility model relates to the field of textile technology, and more specifically, to a light-blocking fabric. Background Technology

[0002] With economic development, people's requirements for clothing are constantly increasing. In order to prevent their skin from being sunburned when going out in the hot summer, they usually wear clothing with sun protection functions. Chemical fibers, due to their tight molecular structure, can effectively block sunlight penetration and are therefore widely used in the production of sun protection clothing, face towels, arm sleeves, umbrellas, tents and other products.

[0003] However, the tight molecular structure of chemical fibers reduces the open space within the fiber, which is not conducive to the circulation of gas. At the same time, in order to ensure the light-blocking effect, the weaving density of the fabric is usually increased or a sun-protective coating is added, which further reduces the air circulation on both sides of the fabric, making the fabric feel stuffy when worn and affecting the comfort of wearing the fabric.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a light-blocking fabric that improves breathability while ensuring the light-blocking property of the fabric through a new structural design.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a light-blocking fabric, comprising an inner layer and an outer layer, wherein the inner layer is provided with a plurality of support blocks on the side near the outer layer, and the outer layer is provided with a plurality of support strips on the side near the inner layer, wherein the inner layer and the outer layer are supported by the plurality of support blocks and the plurality of support strips to form a plurality of ventilation cavities and a plurality of breathable cavities, wherein the inner layer is provided with a plurality of breathable grooves communicating with the ventilation cavities, and the outer layer is provided with a plurality of breathable holes communicating with the breathable cavities, wherein the plurality of breathable grooves and the plurality of breathable holes are staggered along the length direction of the inner layer.

[0007] The present invention is further configured such that: a plurality of the support blocks are arranged in an array along the width direction of the inner layer, and a plurality of ventilation grooves are formed between a plurality of adjacent support blocks along the width direction of the inner layer, wherein the ventilation grooves are interconnected with the ventilation cavity and the ventilation air cavity.

[0008] The present invention is further configured such that: the side length of the support block is the same as the width of the support strip, and a plurality of the support strips are arranged in an array above the plurality of support blocks along the length direction of the outer layer, and the support blocks and support strips are perpendicular to each other.

[0009] The present invention is further configured such that: the inner layer has a plurality of recesses on the side away from the outer layer that correspond to a plurality of support blocks; the inner layer and the outer layer are fixed together by sew-on light-blocking yarn at the point where the support strip and the support block abut; and the warp and weft yarns of the outer layer are both set as light-blocking yarns.

[0010] The present invention is further configured such that: the light-blocking yarn is formed by twisting multiple strands of first strand, and the first strand is formed by twisting acrylic fibers.

[0011] The present invention is further configured such that: both the warp and weft yarns of the inner layer are set as diverging yarns, and the diverging yarns are made by spirally winding a second strand around a first strand, the second strand being made of twisted bamboo charcoal fiber.

[0012] In summary, this utility model has the following beneficial effects: the air circulation effect on both sides of the fabric is improved by several interconnected ventilation cavities, breathable cavities, breathable holes, breathable grooves, and breathable channels, thereby obtaining good breathability and moisture dissipation. At the same time, the staggered arrangement of several breathable holes and several breathable grooves can prevent sunlight from directly penetrating the fabric. Acrylic fiber has good light-blocking properties, so the outer layer can effectively block sunlight penetration. The inner layer made of bamboo charcoal fiber has the effect of absorbing and dispersing sunlight, thereby weakening the intensity of sunlight entering the fabric through the ventilation holes and making it difficult to penetrate the inner layer. This makes the fabric have good breathability while ensuring the sun protection effect. Attached Figure Description

[0015] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0016] Example: A light-blocking fabric, such as Figure 1 , Figure 2 and Figure 5As shown, the structure includes an inner layer 1 and an outer layer 2 that are fixedly connected to each other. Several arrayed ventilation slots 7 are cut into the inner layer 1 using a laser cutting machine, providing ventilation for the inner layer 1. Several square support blocks 3 are provided on the side of the inner layer 1 closest to the outer layer 2, arranged in an array along the width direction of the inner layer 1. Several recesses 10 are provided on the side of the inner layer 1 furthest from the outer layer 2, with the support blocks 3 and recesses 10 corresponding vertically. The warp and weft yarns of the inner layer 1 are both set to diverge. Yarn 13, inner layer 1 is made by feeding the diverging yarn 13 into the multi-arm loom and weaving it with a plain weave small jacquard structure, so that the side of the inner layer 1 with floats forms a support block 3, and the side of the inner layer 1 away from the support block 3 forms a depression 10 due to the lack of float thickness. Since the warp and weft yarns are interwoven in the plain weave weave section of the inner layer 1, the cut ventilation groove 7 on the plain weave weave section of the inner layer 1 is not easy to loosen, and the stability of the inner layer 1 structure can still be maintained.

[0017] like Figure 1 , Figure 2 and Figure 5 As shown, the diverging yarn 13 is made by spirally winding a second strand 14 onto a first strand 12 using a ring spinning machine. The first strand 12 is made by twisting acrylic fibers using a twisting machine. Acrylic fibers can absorb and scatter light due to the -CN group (cyano group) in their chemical structure, thus effectively blocking sunlight penetration and providing good sun protection. This gives the core of the diverging yarn 13 good light-blocking properties. The second strand 14 is made by twisting bamboo charcoal fibers using a twisting machine. Bamboo charcoal fibers have good moisture absorption and breathability, giving the inner layer 1 good breathability. It is not easy to feel stuffy when wearing it and can absorb sweat produced by the skin in time. Several indentations 10 reduce the contact area between the inner layer 1 and the skin, thereby increasing the gap between the inner layer 1 and the skin. This makes the inner layer 1 less likely to stick to the skin surface due to sweat, improving the wearing comfort of the fabric.

[0018] like Figures 1-4As shown, the outer layer 2 has several ventilation holes 8, which improves the breathability of the outer layer 2. Several support strips 4 are provided on the side of the outer layer 2 near the inner layer 1. The length of the support strips 4 is the same as the width of the outer layer 2. The warp and weft yarns of the outer layer 2 are both set as light-blocking yarns 11. The outer layer 2 is made by feeding the light-blocking yarns 11 into an air-jet loom and weaving them alternately with raised stripe weave and perforated weave. The ventilation holes 8 are all integrally formed on the outer layer 2 by the perforated weave. The support strips 4 are all integrally formed on the outer layer 2 by the raised stripe weave. The light-blocking yarns 11 are formed by twisting three strands of the first strand 12 by a twisting machine, so that the outer layer 2 can effectively block sunlight penetration and has a good sun protection effect. Several ventilation grooves 7 and several ventilation holes 8 are staggered along the length direction of the inner layer 1, so as to ensure the breathability of the fabric while preventing sunlight from directly penetrating the fabric.

[0019] like Figures 1-4 As shown, the width of the support strip 4 is the same as the side length of the support block 3. Several support strips 4 are arranged in an array above several support blocks 3 along the length direction of the outer layer 2. The inner layer 1 and the outer layer 2 are located at the support strips 4 and the support blocks 3 and are sewn together by a sewing machine using light-blocking yarn 11, so that the support blocks 3 and the support strips 4 are perpendicular to each other. Acrylic fibers have high strength, thereby ensuring the fixing effect on the inner layer 1 and the outer layer 2. Several ventilation cavities are formed between the inner layer 1 and the outer layer 2 by the support blocks 3 and the support strips 4. 5 and several breathable cavities 6, several ventilation grooves 9 are formed between several adjacent support blocks 3 along the width direction of the inner layer 1, several ventilation grooves 7 on the inner layer 1 are interconnected with several ventilation cavities 5, several ventilation holes 8 on the outer layer 2 are interconnected with several ventilation cavities 6, and the ventilation cavities 6 are interconnected with the ventilation cavities 5 through several ventilation grooves 9. The air circulation effect on both sides of the fabric is improved through several interconnected ventilation cavities 5, ventilation cavities 6, ventilation holes 8, ventilation grooves 7 and ventilation grooves 9, thereby enhancing the breathability of the fabric.

[0020] like Figures 1-3 As shown, the good air circulation effect can remove the moisture absorbed by the fabric in time, thereby keeping the inner layer 1 and the skin dry. Due to its special porous structure, bamboo charcoal fiber can effectively absorb and diffuse sunlight. The light entering the fabric from several ventilation holes 8 will be refracted multiple times in the ventilation cavity 5 and ventilation cavity 6. At the same time, the bamboo charcoal fiber in the inner layer 1 can absorb and scatter the light during the refraction process, thereby weakening the intensity of the light entering the fabric from the ventilation holes 8, making it difficult to penetrate the inner layer 1. This makes the fabric have both good light blocking and breathability.

[0021] like Figures 1-5As shown, when it is necessary to make this kind of light-blocking fabric, first use a laser cutting machine to cut several breathable grooves 7 on the inner layer 1, then lay the cut inner layer 1 flat with the side with the support block 3 facing up, and cover the inner layer 1 with the side with the support strip 4 on the woven outer layer 2, move the outer layer 2 until the support strip 4 and the support block 3 are against each other, and finally use a sewing machine to sew the inner layer 1 and the outer layer 2 at the point where the support strip 4 and the support block 3 are against each other, thereby completing the production of this kind of light-blocking fabric.

All technical solutions falling within the scope of this utility model's concept are protected.
