Description

Technical Field

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

[0002] In the hot summer, people usually wear sun-protective clothing to prevent their skin from being sunburned when they go out. Polyester fabric is a chemical fiber fabric woven from polyester fibers. Due to its tight molecular structure, polyester fibers can effectively block the penetration of sunlight. At the same time, the benzene ring and ester groups contained in polyester fibers can effectively absorb ultraviolet rays in sunlight, so clothing made of polyester fabric has a good sun protection effect.

[0003] However, the tight molecular structure of polyester fibers reduces the internal open space, which is not conducive to the circulation of gas and the penetration and diffusion of moisture. This makes polyester fibers relatively poor in terms of breathability and moisture wicking. In addition, in order to ensure good sun protection performance of the fabric, the weaving density is usually increased, which reduces the breathability of polyester fabric. As a result, clothing made of polyester fabric is prone to feeling stuffy and hot when worn, and sweat cannot be wicked away from the fabric in time and remains on the skin surface, affecting the comfort of wearing it.

[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 sun protection fabric.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a sun-protective fabric, comprising an inner layer and a radiating layer, wherein the inner layer comprises a plurality of light-blocking portions and a plurality of breathable portions arranged alternately along its length direction, wherein the light-blocking portions are provided with a plurality of sun-protective layers on the side near the radiating layer, and the sun-protective layers are fixedly connected to a radiating element on the side away from the inner layer, wherein the inner layer and the radiating layer are supported by a plurality of radiating elements to form a ventilation cavity, wherein the ventilation portions are arrayed with a plurality of ventilation holes communicating with the ventilation cavity, and wherein the radiating layer is provided with a plurality of through holes arranged alternately with the ventilation portions.

[0007] The present invention is further configured such that: a plurality of the sun protection layers are arranged in an array along the width direction of the inner layer, and the side of the radiating element away from the inner layer abuts against the radiating layer.

[0008] The present invention is further configured such that: the sun protection layer is made of TPU material, and the radiating component is made of bamboo charcoal short fibers flocked on the sun protection layer.

[0009] The present invention is further configured such that: the diameter of the through hole is smaller than the side length of the diverging component; an array of through holes is arranged above a plurality of diverging components; and the through holes are interconnected with the ventilation cavity through gaps within the diverging components.

[0010] The present invention is further configured such that: both the warp and weft yarns of the inner layer are set as light-blocking yarns, and the light-blocking yarns are formed by twisting multiple strands of first strand, which are made of polyester fibers.

[0011] The present invention is further configured such that: both the warp and weft yarns of the diverging layer are diverging yarns, and the diverging yarns are formed by twisting a second strand and a third strand, wherein the second strand is formed by twisting polyester profiled fibers and the third strand is formed by twisting bamboo charcoal fibers.

[0012] In summary, this utility model has the following beneficial effects: The air circulation inside and on both sides of the fabric is improved by the interconnected ventilation holes, diffusers, and through-holes, thereby enhancing breathability and moisture wicking speed. The staggered arrangement of through-holes and ventilation holes prevents sunlight from directly penetrating the fabric and shining on the skin. Bamboo charcoal fiber has the effect of absorbing and diffusing sunlight. The diffusers made of bamboo charcoal fiber below the through-holes diffuse sunlight entering through them, thus reducing the intensity of sunlight. The sun-protective layer made of TPU material forms a physical barrier, further limiting sunlight penetration into the inner layer. The inner layer made of polyester fiber has good light-blocking properties, causing sunlight entering through the through-holes to undergo multiple refractions or scatterings between the diffusers, the inner layer, and the diffuser layer, thereby continuously reducing the intensity of sunlight and making it difficult for it to penetrate the inner layer. This ensures that the fabric has good breathability and moisture wicking while maintaining sun protection. Attached Figure Description

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] Example: A sun-protective fabric, such as Figures 1-5 As shown, the structure includes an inner layer 1 and a radiating layer 2 that are stitched together. The inner layer 1 includes several light-blocking portions 101 and several breathable portions 102 arranged alternately along its length. The breathable portions 102 are arrayed with several breathable holes 6, which improve the breathability of the inner layer 1. Both the warp and weft yarns of the inner layer 1 are light-blocking yarns 8. The inner layer 1 is made by feeding the light-blocking yarns 8 into the loom and weaving them alternately using plain weave and openwork weave. The light-blocking portions 101 are woven using a plain weave... The light-blocking part 101 is integrally formed on the inner layer 1. Several breathable parts 102 and several breathable holes 6 are integrally formed on the inner layer 1 by the weaving of the perforated structure. The light-blocking yarn 8 is formed by twisting three strands of the first strand 9 by a twisting machine. The first strand 9 is formed by twisting polyester fibers by a twisting machine. Due to its tight molecular structure, polyester fiber can effectively block the penetration of sunlight. At the same time, the benzene ring and ester group contained in polyester fiber can effectively absorb ultraviolet rays in sunlight, so that the light-blocking part 101 can effectively block the penetration of sunlight.

[0022] like Figures 1-4As shown, the light-shielding part 101 has several sun-protective layers 3 on the side near the radiating layer 2. A radiating element 4 is fixedly connected to the side of the sun-protective layer 3 away from the inner layer 1. The sun-protective layer 3 is formed by coating the light-shielding part 101 with TPU coating. The radiating element 4 is formed by flocking bamboo charcoal short fibers onto the TPU coating. The several sun-protective layers 3 are arranged in an array along the width direction of the inner layer 1. The side of the radiating element 4 away from the inner layer 1 abuts against the radiating layer 2, so that the inner layer 1 and the radiating layer 2 are supported by the several radiating elements 4 to form a ventilation cavity 5 with a grid-like cross-section. Several ventilation holes 6 on the ventilation part 102 are all interconnected with the ventilation cavity 5. The radiating layer 2 is formed by laser cutting. The cutting machine creates several through holes 7, the diameter of which is smaller than the side length of the diffuser 4. The array of through holes 7 is arranged above the diffuser 4, so that the side of the diffuser 4 away from the inner layer 1 abuts against the opening of the through hole 7. The diffuser 4, which is made of bamboo charcoal fiber flocking, will form dense gaps inside. The through holes 7 are interconnected with the ventilation cavity 5 through the gaps inside the diffuser 4. The air circulation effect inside and on both sides of the fabric is improved by the several ventilation holes 6, the diffuser 4, and the through holes 7 that are interconnected with the ventilation cavity 5. The good air circulation effect enhances the moisture wicking and breathability of the fabric, making the finished fabric dry and breathable to wear.

[0023] like Figures 1-4 As shown, several ventilation holes 6 and several through holes 7 are staggered along the length of the inner layer 1, which can prevent sunlight from directly penetrating the fabric and shining on the skin. Bamboo charcoal fiber has the effect of scattering sunlight. By setting a scattering element 4 made of bamboo charcoal fiber below the through holes 7, the sunlight entering from the through holes 7 can be scattered, thereby reducing the intensity of sunlight. The TPU material has a certain density and thickness, so that the sun protection layer 3 can form a physical barrier on the light-blocking part 101 to limit the penetration of sunlight into the light-blocking part 101. The inner layer 1 made of polyester fiber has good light-blocking properties, so that the sunlight entering from the through holes 7 will be refracted or scattered multiple times between the scattering element 4 and the inner layer 1 and the scattering layer 2, thereby continuously reducing the intensity of sunlight. This makes it difficult for sunlight entering the fabric from the through holes 7 to penetrate the inner layer 1, thus ensuring a good sun protection effect.

[0024] like Figure 1 and Figure 6 As shown, both the warp and weft yarns of the diverging layer 2 are set as diverging yarns 10. The diverging layer 2 is made by feeding the diverging yarns 10 into the loom and weaving them with a plain weave. The diverging yarns 10 are formed by twisting a second strand 11 and a third strand 12 through a twisting machine. The second strand 11 is formed by twisting polyester profiled fibers with a trilobal cross-section through a twisting machine. The polyester profiled fibers with a trilobal cross-section are spun through a spinneret with trilobal openings. By shaping the polyester fibers, the porosity and surface area within the fibers are increased, and the porosity formed by the shaping improves the sunlight diffusion effect.

[0025] like Figure 1 , Figure 4 and Figure 6 As shown, the third strand 12 is made by twisting bamboo charcoal fiber using a twisting machine. Bamboo charcoal fiber has better moisture absorption and breathability than polyester profiled fiber. The natural irregular porous structure of bamboo charcoal fiber can effectively diffuse sunlight and has the characteristic of rapid moisture dissipation. The diameter of the second strand 11 is larger than that of the third strand 12, so that the surface of the twisted diverging yarn 10 is continuously uneven. This makes the surface of the diverging layer 2 woven from the diverging yarn 10 uneven. Therefore, the diverging layer 2 can effectively diffuse sunlight and provide good sun protection. The sun protection layer 3 formed by TPU coating has good moisture permeability. The diverging layer 2 and the diverging component 4 made of bamboo charcoal fiber have better moisture absorption than the inner layer 1. This allows the moisture absorbed in the inner layer 1 to pass through several sun protection layers 3 and several diverging components 4 to be quickly dissipated to the outer layer, thereby keeping the inner layer 1 and the skin dry and further improving the comfort of the fabric when worn.

[0026] When this type of sun-protective fabric is to be made, firstly, the light-blocking yarn 8 is fed into the loom and woven using a plain weave and perforated weave to form the inner layer 1. Then, the diverging yarn 10 is fed into the loom and woven using a plain weave to form the diverging layer 2. Next, several through holes 7 are opened on the diverging layer 2 using a laser cutting machine. After coating the inner layer 1 with TPU coating using a coating machine, bamboo charcoal short fibers are flocked onto the TPU coating to form diverging elements 4 using a flocking process. The flocked inner layer 1 is then transported to a drying chamber for heating and shaping, so that the TPU coating is cured to form the sun-protective layer 3. The shaped inner layer 1 is laid flat with the side containing the diverging elements 4 facing upwards. The diverging layer 2 is then placed on top of the inner layer 1. The diverging layer 2 is moved so that the several through holes 7 are positioned above the several diverging elements 4. Finally, the inner layer 1 and the diverging layer 2 are sewn together using a sewing machine with the light-blocking yarn 8 to complete the production of this type of sun-protective fabric.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
