Description

Technical Field

[0001] The invention relates to the field of fabrics, and more specifically, to a sun-proof and rain-proof fabric and a weaving process thereof. Background Art

[0002] The sun-proof and rain-proof fabrics currently on the market have increased their sun-proof and rain-proof properties, making the entire fabric non-breathable due to the use of coating additives. Summary of the invention

[0003] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art and provide a sun-proof and rain-proof fabric and its weaving process. The three-layer fabric formed by weaving is sewn and stitched. The water-repellent porous layer formed by weaving replaces the existing film formed by coating, so that it is breathable, and the hydrophilic layer absorbs the water vapor of the water-repellent porous layer. The sun-proof and rain-proof layer is woven by combining yarns to form a sun-proof area and a rain-proof area. The sun-proof area is woven by anti-ultraviolet yarns, and the rain-proof area is woven by expanded yarns. When in a natural state, a concave-convex height difference is formed between the sun-proof area and the rain-proof area, which increases the refraction and reflection of the sun-proof area. The rain-proof area and the hydrophilic layer form a cavity to increase air flow, thereby keeping the fabric dry. When in a water-absorbing state, the expanded yarn in the rain-proof area swells when exposed to water and covers the sun-proof area, and the gap between the expanded yarns is between 0.5 and 2 nanometers, which reduces the entry of water droplets while allowing water vapor molecules to be discharged, thereby making the fabric not only rain-proof and sun-proof but also breathable.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] like Figure 1 As shown in FIG. 10 , a sun-proof and rain-proof fabric comprises, from the inside to the outside, a water-repellent porous layer 10, a hydrophilic layer 20, and a sun-proof and rain-proof layer 30. The water-repellent porous layer 10 comprises a base 11 and air holes 12. Figure 3The air holes 12 are hollow and distributed in a diamond shape on the base 11, and the base 11 is formed by weaving polypropylene fibers 13. The twist of the polypropylene fibers 13 is large, so that the surface of the yarn formed by twisting the polypropylene fibers 13 forms tiny protrusions and depressions. The polypropylene fibers 13 with a relatively rough surface can form adsorption and repulsion on the base 11 formed by weaving the polypropylene fibers 13 when contacting the water vapor generated during use. Therefore, when the water vapor adsorbed by the base 11 is absorbed by the hydrophilic layer 20, because the hydrophilic layer 20 is woven by cotton fibers 21, and the official moisture regain of the cotton fibers 21 is 8.5%, so the hydrophilic layer 20 has good hygroscopicity. When the water vapor generated during use is conducted to the hydrophilic layer 20 through the water-repellent porous layer 10, the water vapor is absorbed by the cotton fibers 21, and the water vapor repelled by the base 11 is directly guided to the hydrophilic layer 20 through the air holes 12, so that the hydrophilic layer 20 absorbs the generated water vapor, thereby keeping the water-repellent porous layer 10 dry and increasing the air permeability of the fabric through the air holes 12.

[0036] The sunscreen and rainscreen layer 30 includes a sunscreen area 31 and a rainscreen area 32. The rainscreen area 32 is formed by weaving expansion yarns 33, and the sunscreen area 31 is formed by weaving anti-ultraviolet yarns 34. Figure 1 In a natural state, the rainproof area 32 is higher than the sunscreen area 31, and the rainproof area 32 and the sunscreen area 31 are distributed in a concave-convex manner, and the height H formed by the sunscreen area 31 and the rainproof area 32 is 1.5 mm-4 mm. Preferably, the height H formed by the sunscreen area 31 and the rainproof area 32 is 2.85 mm. Therefore, when ultraviolet rays are irradiated, the surface concave-convex structure formed by the sunscreen and rainproof layer 30 not only makes the sunscreen area 31 absorb light, but also increases the reflection of light due to the angle formed by the concave-convex between the sunscreen area 31 and the rainscreen area 32, thereby reducing the transmittance of ultraviolet rays. Figure 4 Because the sunscreen area 31 and the rainscreen area 32 are spaced apart, when ultraviolet rays irradiate the surface of the fabric, the spaced apart structure increases the scattering of light, thereby reducing the penetration of ultraviolet rays into the fabric, and the sunscreen area 31 is woven more tightly than the rainscreen area 32, so the rainscreen area 32 increases the tightness of the fabric and reduces the transmittance of ultraviolet rays. The sunscreen area 31 can form air circulation between the outside air and the fabric without affecting the anti-ultraviolet performance, so that the water vapor absorbed by the hydrophilic layer 20 can be released through air circulation, thereby keeping the hydrophilic layer 20 dry and breathable.

[0037] Reference Figure 2In the water absorbing state, the rainproof area 32 expands to cover the sunscreen area 31, and the rainproof area 32 is located above the sunscreen area 31, and expands to cover both sides of the sunscreen area 31, because the rainproof area 32 is woven by the expansion yarn 33, and the expansion yarn 33 is formed by the combination of ultrafine denier fiber and super absorbent resin by spinning. In the natural state, the expansion yarn 33 has a weaving structure that makes the gap between the yarns larger than the diameter of the raindrops, so that the raindrops can be absorbed when they come into contact with the expansion yarn 33, and when the expansion yarn 33 absorbs water, because the ultrafine denier fiber has many fine pores between the microfibers, not only the fiber surface area is increased, but also because the ultrafine denier The capillary effect formed by the pores of the fibers absorbs moisture quickly. The wicking of the ultrafine denier fibers causes the expanded yarn 33 to absorb water and swell, so that the gap between the yarns in the rainproof area 32 after weaving is 0.5 nanometers to 2 nanometers. Preferably, the gap between the yarns is 2 nanometers, thereby preventing raindrops from continuing to enter. Because the expanded fibers 33 contain highly absorbent resin components, the expanded yarn 33 swells to form a hydrogel after absorbing water, and expands to both sides to cover the sunscreen area 31, so that the rainproof area 32 after absorbing water will not penetrate inward, so that the water-repellent porous layer 10 and the hydrophilic layer 20 remain dry, and can resist rainwater outward, thereby forming a rainproof area.

[0038] When the external moisture no longer increases, after absorbing water, due to the external air circulation or a certain pressure, the moisture evaporates through the tiny pores between the microfibers of the expanded yarn 33, causing the formed hydrogel to slowly lose water. As the expanded yarn 33 loses more moisture, more tiny pores appear between the microfibers of the expanded yarn 33, thereby expanding the air flow range and evaporating the moisture faster, so that the fabric slowly returns to its natural state.

[0039] The sun protection area 31 is close to the hydrophilic layer 20, and the rain protection area 32 forms a cavity 40 with the hydrophilic layer 20. In the natural state, the cavity 40 formed between the rain protection area 32 and the hydrophilic layer 20 can increase the air circulation of the hydrophilic layer 20 after absorbing the water vapor of the water-repellent porous layer 10, thereby increasing the air permeability of the hydrophilic layer 20 and accelerating the water release of the hydrophilic layer 20, so that the hydrophilic layer 20 remains dry. In the water absorbing state, the rain protection area 32 expands to cover the sun protection area 31. At this time, the cavity 40 formed between the rain protection area 32 and the hydrophilic layer 20 forms a heat storage cavity, thereby alleviating the temperature loss caused by the increase in ambient humidity.

[0040] The water-repellent porous layer 10, the hydrophilic layer 20, and the sunscreen and rainproof layer 30 are connected by sewing, so that the three layers are not easily separated, and the environmental pollution caused by gluing is reduced, which is beneficial to human health.

[0041] The water-repellent porous layer 10 is woven with polypropylene fiber 13, with 8 rows of coils as one cycle, the 3rd row of the 1st longitudinal row is a tuck, the 1st, 2nd, 4th, 5th, 6th, 7th, and 8th rows of coils are plain needles, the 1st and 5th rows of the 3rd and 7th longitudinal rows are tucks, the 2nd to 4th, 6th to 8th rows of coils are plain needles, the 7th row of the 5th longitudinal row is a tuck, the 1st to 6th and 8th rows of coils are plain needles, and the 1st to 8th rows of coils of the 2nd, 4th, 6th, and 8th longitudinal rows are all plain needles. The hydrophilic layer 20 is woven with cotton fiber 21, and the hydrophilic layer 20 is woven with 4 rows of coils as one cycle, the 1st to 5th rows of the 3rd and 7th longitudinal rows are tucks, the 2nd to 4th, 6th to 8th rows of coils are plain needles. The 1st, 2nd, 3rd and 4th row of stitches are all plain needles, and the water-repellent porous layer 10 and the hydrophilic layer 20 are woven with a tube diameter of 24 inches at 18 needles / inch, so that the water-repellent porous layer 10 forms air holes 12 through the tucking knitting of the polypropylene fiber 13, thereby increasing the air permeability of the water-repellent porous layer 10, and the plain knitting of the polypropylene fiber 13 forms the base 11, so that the polypropylene fiber 13 can absorb part of the water vapor, and the hydrophilic layer 20 absorbs all the water vapor through the plain knitting of the cotton fiber 21, and because the plain knitting is adopted, the hydrophilic layer 20 absorbs water more evenly, thereby keeping the water-repellent porous layer 10 dry.

[0042] The sunscreen and rainproof layer 30 is woven with an expansion yarn 33 and an anti-ultraviolet yarn 34, and the expansion yarn 33 and the anti-ultraviolet yarn 34 are arranged in a 1:1 ratio. The sunscreen and rainproof layer 30 has 8 coil rows as one cycle, and each coil row includes an upper needle and a lower needle. The 1st, 3rd, 5th, and 7th coil rows are the anti-ultraviolet yarn 34, and the 2nd, 4th, 6th, and 8th coil rows are the expansion yarn 33. The 1st coil row is the 3rd and 4th lower needles are looped, and the 1st and 2nd lower needles are not knitted, the 1st and 3rd upper needles are looped, and the 2nd and 4th upper needles are not knitted. , the 2nd and 4th row of loops are that the 1st and 2nd needles are looped, the 3rd and 4th needles are not knitted, and the 1st, 2nd, 3rd and 4th needles are not knitted. The 3rd row of loops is that the 1st and 2nd needles are not knitted, the 3rd and 4th needles are looped, the 1st and 3rd needles are not knitted, and the 2nd and 4th needles are looped. The 5th row of loops is that the 1st and 2nd needles are looped, the 2nd and 4th needles are not knitted, the 1st and 3rd needles are looped, and the 2nd and 4th needles are not knitted. The 6th and 8th row of loops are that the 1st and 2nd needles are not knitted, the 3rd and 4th needles are looped, and the 1st, 2nd, 3rd and 4th needles are not knitted. The 7th row of coils is that the 1st and 2nd lower needles form a loop, the 3rd and 4th lower needles are not knitted, the 1st and 3rd upper needles are not knitted, and the 2nd and 4th upper needles form a loop. The sunscreen and rainproof layer 30 adopts a tube diameter of 36 inches, the sunscreen area 31 is knitted with 28 needles / inch, and the rainscreen area 32 is knitted with 44 needles / inch. In a natural state, the rainscreen area 32 and the sunscreen area 31 form a concave-convex interval distribution, and the height H formed by the sunscreen area 31 and the rainscreen area 32 is 1.5mm-4mm. Preferably, the height H formed by the sunscreen area 31 and the rainscreen area 32 is 2.85mm. The anti-ultraviolet yarn 34 is woven to form a height difference between the sun protection area 31 and the rain protection area 32, and the reflection and scattering are increased through the angle. The expanded yarn 33 is formed into fibers by spinning ultrafine denier fibers and highly absorbent resin, and the expanded yarn 33 is post-treated after spinning to increase the tensile strength and toughness of the expanded yarn. In the water-absorbing state, the rain protection area 32 is located above the sun protection area 31, and the rain protection area 32 expands and covers both sides of the sun protection area 31, so that the expanded yarn 33 will not break due to expansion to both sides due to water absorption.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention.
