Description

Technical Field

[0001] This invention relates to the field of textile fabric technology, and more specifically, to waterproof and UV-resistant polyester fabric and its processing technology. Background Technology

[0002] With the development of society and economy and the improvement of people's living standards, the requirements for the characteristics of clothing fabrics are also constantly increasing. Waterproof fabric is a new type of textile fabric, which is made by combining a polymer waterproof membrane with fabric, giving it properties such as oil repellency, water repellency, water pressure resistance, moisture resistance, and insulation. It is often used to make outdoor clothing such as windbreakers and raincoats.

[0003] A Chinese utility model patent with publication number CN213798427U describes a waterproof fabric. This fabric achieves a waterproof effect by using cotton fiber blocking balls that expand after absorbing water to seal the vents. However, once the blocking balls reach moisture saturation, moisture will overflow from the blocking balls into the grooves. The inner layer is woven with warp and weft yarns in a one-up-one-down cyclic pattern, resulting in dense pores in the inner layer. Moisture in the grooves can penetrate the inner layer through these gaps, making the fabric unable to achieve a continuous waterproof effect.

[0004] Therefore, a new solution is needed to address this problem. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide waterproof and UV-resistant polyester fabric and its processing technology to solve the problem that setting expansion elements in the fabric cannot achieve a continuous waterproof effect.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: the waterproof and UV-resistant polyester fabric includes an inner layer and a sun-protective layer that are fixedly connected to each other. The end face of the sun-protective layer away from the inner layer is covered with a waterproof layer and simultaneously has a plurality of arrayed vent holes. An expansion member is provided between the inner layer and the sun-protective layer to seal the vent holes after absorbing water. The end face of the expansion member near the sun-protective layer is sprayed to form a sealing layer. The inner layer is sprayed around the expansion member to form a diversion layer for gathering water that enters the fabric from the vent holes to the periphery of the expansion member.

[0007] The present invention is further configured such that: the diameter of the sealing layer is larger than the diameter of the vent hole, the hygroscopicity of the expansion member is greater than that of the inner layer, and the flow guiding layer and the expansion member form a hygroscopic port.

[0008] The invention is further configured such that: the inner layer and the sun protection layer have several recesses on their end faces that are close to each other, which are arranged along the length of the fabric, and the expansion member is fixedly connected to the bottom of the recesses.

[0009] The present invention is further configured such that: a plurality of vent holes on the sunscreen layer all penetrate the bottom of the recess on the sunscreen layer, and the height of the sealing layer is less than the height of the bottom of the recess on the sunscreen layer.

[0010] The present invention is further configured such that: a plurality of support members are provided between the inner layer and the sun protection layer, and the adjacent support members and the inner layer and the sun protection layer enclose a ventilation space.

[0011] The present invention is further configured such that: the end face of the support member near the sun protection layer is provided with a plurality of grooves communicating with the ventilation space, and the inner layer is provided with a plurality of ventilation holes communicating with the ventilation space.

[0012] The present invention is further configured such that the processing technology of the waterproof and UV-resistant polyester fabric includes an equipment body, a support frame slidably connected to the equipment body along its length direction, a moving platform slidably connected to the inner side of the support frame along the height direction of the equipment body, and a plurality of spraying devices for spraying to form a sealing layer and a guide layer slidably connected to the moving platform along the width direction of the equipment body.

[0013] The present invention is further configured such that: the spraying device is provided with an adjustment device for adjusting its spraying range, a limiting member is provided at one end of the spraying device near the fabric, and a material conveying pipe is provided at the top of the spraying device in communication with it.

[0014] The present invention is further configured such that: a storage tank is fixedly connected to one side of the length of the equipment body, the end of the conveying pipe away from the spraying device is connected to the top of the storage tank, and the top of the storage tank is provided with a drive device for controlling the operation of the spraying device.

[0015] The present invention is further configured as follows: a processing method for waterproof and UV-resistant polyester fabric, the processing of which includes,

[0016] Step 1: Heat-press indentations into the inner layer and sun protection layer;

[0017] Step 2: Secure the expansion component to the bottom of the recess on the inner layer;

[0018] Step 3: Secure the support to the end face of the inner layer located between adjacent recesses;

[0019] Step 4: Convey the inner layer, which is fixedly connected to the expansion member and the support member, onto the equipment body;

[0020] Step 5: Adjust the positions of the support frame, moving platform, and several spraying devices so that the spraying devices are positioned close to and directly above the expansion component;

[0021] Step 6: Set the appropriate spraying range of the spraying device by rotating the adjustment device.

[0022] Step 7: Control the spraying device through the drive device to spray the fabric at intervals onto the inner wall of the expansion part and the recess to form a sealing layer and a guide layer.

[0024] Step 9: Simultaneously create an array of ventilation holes at the bottom of the recesses on both the waterproof and sun-protective layers;

[0025] Step 10: Sew the inner layer and the sun protection layer together.

[0026] In summary, the present invention has the following beneficial effects: the sun-protective layer made of polyester and acrylic fibers gives the fabric a good sun protection effect. By adding a waterproof layer made of PTFE film on the sun-protective layer, liquid moisture can be prevented from entering the fabric while allowing gas molecules to pass through, thus achieving a waterproof and breathable effect and avoiding stuffiness when wearing it. The vents on the waterproof layer further improve the breathability of the fabric. Through the sealing layer and the diversion layer, moisture entering the fabric from the vents can be gathered around the expansion element in time. The expansion element can immediately absorb the moisture and expand to seal the vents, preventing moisture from continuing to enter the fabric and achieving a continuous waterproof effect. The interconnected vents, air holes, grooves and ventilation spaces improve the air circulation effect inside the fabric and diffuse the sunlight entering the fabric, reducing the intensity of sunlight and further improving the sun protection effect of the fabric. The inner layer made of cotton fibers improves the wearing comfort of the fabric. Attached Figure Description

Detailed Implementation

[0036] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0037] Example: This waterproof and UV-resistant polyester fabric, such as Figure 1 , Figure 3 and Figure 6 As shown, the device includes an inner layer 1 and a sun protection layer 2 that are fixedly connected to each other. The inner layer 1 is woven by placing comfort yarn 27 into an air-jet loom and using a perforated weave. Several arrays of square ventilation holes 12 on the inner layer 1 are integrally formed by the perforated weave. The comfort yarn 27 includes a comfort yarn core and a comfort covering yarn spirally wound on its outer side. The comfort yarn core is made by twisting polyester profiled fibers 28 with a triangular cross-section. The comfort covering yarn is made by twisting cotton fibers 29. Cotton fibers 29 have good moisture absorption and can absorb sweat produced by the wearer's skin in time, keeping the skin dry. Comfortable and soft to the touch, the inner layer 1 is made of cotton fiber 29, which enhances the comfort of the inner layer when in contact with the skin. The triangular cross-section of polyester profiled fiber 28 is formed by spinning through a spinneret. The polyester profiled fiber 28 has high strength and abrasion resistance, which improves the service life of the fabric. The numerous irregular pores in the cotton fiber 29 and the triangular cross-section of the polyester profiled fiber 28 can change the direction of the optical fiber, which can diffuse and reduce the intensity of sunlight. At the same time, the numerous pores in the cotton fiber 29 and the triangular cross-section of the polyester profiled fiber 28 improve the breathability of the inner layer 1, preventing the user from feeling stuffy when wearing it.

[0038] like Figure 1 and Figure 7As shown, the sun protection layer 2 is made by weaving sun protection yarn 30 into a plain weave on an air-jet loom with a weave density of 184*172. The sun protection yarn 30 is formed by twisting the first and second strands using a twisting machine. The first strand is formed by twisting polyester fiber 31, and the second strand is formed by twisting acrylic fiber 32. Polyester fiber 31 has good light resistance, while acrylic fiber 32 has better light resistance than polyester fiber 31, enabling the sun protection layer 2 to effectively resist sunlight and ultraviolet rays. The increased weave density of the sunscreen layer 2 further restricts sunlight penetration, giving it excellent sun protection properties and preventing direct sunlight from damaging the skin. A waterproof layer 35 is applied to the end of the sunscreen layer 2 away from the inner layer 1 via heat transfer. This waterproof layer 35 is a PTFE film; its unique microporous structure and hydrophobicity prevent liquid moisture from entering while allowing gas molecules to pass through, achieving a waterproof and breathable effect. This avoids reducing the overall breathability of the fabric after applying the waterproof layer 35.

[0039] like Figures 1-3 As shown, a laser punch is used to simultaneously penetrate the bottom of the recesses 8 on both the waterproof layer 35 and the sun protection layer 2, creating an array of circular ventilation holes 3. This further improves the overall breathability of the fabric. Between the inner layer 1 and the sun protection layer 2, there are several spherical expansion members 4 that seal the ventilation holes 3 after absorbing water. These expansion members 4 are made of sponge, which has strong moisture absorption and can quickly expand to several times its original volume after absorbing water. A hot press is used to hot press several arc-shaped recesses 8 along the length of the fabric onto the end faces of the inner layer 1 and the sun protection layer 2 that are close to each other. The bottom of the recesses 8 on the inner layer 1 is then hot-pressed along the width of the fabric using a hot press. Several semi-circular storage slots are hot-pressed out. After applying glue to the storage slots using a glue applicator, the expansion component 4 is fixedly connected to the storage slot at the bottom of the recess 8 on the inner layer 1. A sealing layer 5 is formed on the end face of the expansion component 4 near the sun protection layer 2 by vertical spraying. The inner layer 1, located around the expansion component 4, forms a flow guiding layer 6 around the expansion component 4 on the inner wall of the recess 8 during vertical spraying. Both the sealing layer 5 and the flow guiding layer 6 are formed by spraying polyurethane coating. The polyurethane coating has good waterproof properties and can resist the effects of ultraviolet rays, high temperature and humid environment, maintaining the stability of the sealing layer 5 and the flow guiding layer 6.

[0040] like Figures 1-3As shown, the sealing layer 5 and the diversion layer 6 form a corresponding arc shape with the shape of the expansion member 4 and the recess 8. The arc-shaped diversion layer 6 is used to gather the moisture that enters the fabric from the vent 3 to the periphery of the expansion member 4. The diversion layer 6 and the periphery of the expansion member 4 form a moisture absorption port 7. Several vent 3 on the sun protection layer 2 penetrate the bottom of the recess 8 on the sun protection layer 2, so that the vent 3 and the recess 8 on the sun protection layer 2 are interconnected. The recess 8 on the inner layer 1 and the recess 8 on the sun protection layer 2 are symmetrically arranged vertically, so that the expansion member 4 is located directly below the vent 3. The height of the sealing layer 5 is less than the height of the bottom of the recess 8 on the sun protection layer 2, so that there is a certain gap between the sealing layer 5 and the recess 8 on the sun protection layer 2.

[0041] like Figure 1 , Figure 3 and Figure 6 As shown, when water enters through the vent 3 and drips onto the top of the expansion member 4, the water slides down the arc of the sealing layer 5 at the top of the expansion member 4 to the guide layer 6. Then, the arc of the guide layer 6 gathers the water into the moisture absorption port 7. The hygroscopicity of the sponge is greater than that of the cotton fiber 29 and the polyester profiled fiber 28, making the hygroscopicity of the expansion member 4 greater than that of the inner layer 1. The expansion member 4 can absorb the water entering the fabric in time, preventing water from passing through the moisture absorption port 7 into the inner layer 1. When the expansion member 4 absorbs water, it expands immediately, causing the height of the expansion member 4 to rise rapidly. The diameter of the sealing layer 5 is greater than the diameter of the vent 3. When the height of the expansion member 4 rises to the point where the sealing layer 5 abuts against the peripheral wall of the vent 3, it seals it. The sealing layer 5 restricts water from continuing to enter the fabric through the vent 3, achieving a continuous waterproof effect.

[0042] like Figure 1 , Figure 3 and Figure 8 As shown, several long strip-shaped support members 9 are provided between the inner layer 1 and the sun protection layer 2 along the length of the fabric. The support members 9 are made by placing high-elastic yarn 33 into an air-jet loom and weaving it into a plain weave fabric, and then using a hot press to hot press several arc-shaped grooves 11 on both sides of the support members 9. The grooves 11 on both sides of the support members 9 are staggered along the width of the fabric. The support members 9 are fixedly connected between the inner layer 1 and the sun protection layer 2 using a glue dispensing machine, and then cut using a cutting machine to form the support members 9. The high-elastic yarn 33 includes a high-elastic yarn core and a high-elastic covering yarn spirally wound on its outer side. The high-elastic yarn 33 is made by processing the high-elastic yarn core and the high-elastic covering yarn through a spinning process. The high-elastic yarn core is made by twisting spandex fiber 34, and the high-elastic covering yarn is made by twisting polyester profiled fiber 28 with a triangular cross section. The spandex fiber 34 has excellent elasticity and elastic recovery ability, which allows the support members 9 to quickly return to their original shape after stretching and is not easily deformed.

[0043] like Figure 1 and Figure 3As shown, several adjacent support members 9, inner layer 1, and sun protection layer 2 enclose several ventilation spaces 10. Several grooves 11 on the support members 9 are interconnected with the ventilation spaces 10, making adjacent ventilation spaces 10 interconnected. Several ventilation holes 12 on the inner layer 1 are interconnected with the ventilation spaces 10. The interconnected ventilation holes 3, ventilation holes 12, and ventilation spaces 10 enhance the air circulation effect inside the fabric and improve the overall breathability of the fabric. At the same time, the ventilation spaces 10 can diffuse sunlight entering the fabric from the ventilation holes 3, reducing the intensity of ultraviolet rays in sunlight, so that the fabric has good waterproof and anti-ultraviolet effects.

[0044] like Figures 4-5 As shown, the processing equipment used to manufacture this waterproof and UV-resistant polyester fabric includes a stainless steel body 13. Stainless steel has strong corrosion resistance, allowing the body 13 to resist most chemical coatings. The high strength of stainless steel enables the body 13 to withstand significant external forces and maintain structural stability. A stainless steel support frame 14 is slidably connected to the body 13 along its length. A drive motor 22 is located on one side of the width of the body 13 to drive the support frame 14 horizontally. A stainless steel moving platform 15 is slidably connected to the inner side of the support frame 14 along the height of the body 13. A drive motor 22 is located at the top of the support frame 14. A drive motor 23 drives the mobile platform 15 to move vertically up and down relative to the equipment body 13. Several spraying devices 16 for spraying to form a sealing layer 5 and a flow guiding layer 6 are slidably connected to the mobile platform 15 along the width direction of the equipment body 13. The spraying devices 16 are made of stainless steel. A U-shaped snap-fit ​​24 is detachably connected to the top of the spraying device 16. This snap-fit ​​24 is injection molded from PVC material with good machinability and moldability. A fixing part 25 is threadedly connected to the side of the snap-fit ​​24 near the width of the spraying device 16. This fixing part 25 is injection molded from PVC material. The position of the spraying devices 16 can be adjusted by rotating the fixing part 25 to adjust the tightness between the snap-fit ​​24 and the mobile platform 15.

[0045] like Figure 5As shown, the spraying device 16 is equipped with an adjustment device 17 for adjusting its spraying range. This adjustment device 17 is made of stainless steel. By rotating the adjustment device 17, the shape, intensity, and size of the sprayed paint can be changed. At one end of the spraying device 16 near the fabric, there is a conical restrictor 18 made of stainless steel. The restrictor 18 can prevent the sprayed liquid from splashing out of the required spraying range. At the top of the spraying device 16, there is a feed pipe 19 connected to it. This feed pipe 19 is made of rubber. Rubber has good wear resistance, elasticity, sealing, waterproof and corrosion resistance, making the feed pipe 19 less prone to breakage and leakage during high-pressure feed.

[0046] like Figures 1-4 As shown, a stainless steel storage tank 20 is fixedly connected to one side of the length of the equipment body 13. The end of the conveying pipe 19 away from the spraying device 16 is connected to the top of the storage tank 20. A feeding pipe 26, made of rubber, is connected to the bottom of the storage tank 20. A drive device 21 for controlling the operation of the spraying device 16 is located at the top of the storage tank 20. This drive device 21 includes a drive motor, a high-pressure water pump, and a controller. The high-pressure water pump draws in compressed high-pressure water, which flows through the high-pressure water pipe and finally through the spraying device 16. The coating is sprayed out. The high-pressure water pump can be controlled by the controller to control the spraying interval of the spraying device 16. When the expansion member 4 on the inner layer 1 is delivered directly below the spraying device 16, it is sprayed. During the spraying process, the end of the expansion member 4 that is far away from the spraying device 16 will not be sprayed with paint due to the diameter of the expansion member 4. Thus, a sealing layer 5 is formed at the end of the expansion member 4 that is close to the spraying device 16, and an annular guide layer 6 is formed around the expansion member 4. The sealing layer 5 and the guide layer 6 can form an annular moisture absorption port 7 located between the expansion member 4 and the guide layer 6.

[0047] like Figures 1-8 As shown, the processing technology for waterproof and UV-resistant polyester fabric includes the following steps:

[0048] Step 1: Heat-press indentations 8 into the inner layer 1 and the sunscreen layer 2;

[0049] Step 2: Secure the expansion member 4 to the bottom of the recess 8 on the inner layer 1;

[0050] Step 3: Fix the support 9 to the end face of the inner layer 1 located between adjacent recesses 8;

[0051] Step 4: Convey the inner layer 1, which is fixedly connected to the expansion member 4 and the support member 9, onto the equipment body 13;

[0052] Step 5: Adjust the positions of the support frame 14, the moving platform 15 and the spraying devices 16 so that the spraying devices 16 are positioned close to the top of the expansion member 4.

[0053] Step 6: Set the appropriate spraying range of the spraying device 16 by rotating the adjustment device 17;

[0054] Step 7: Control the spraying device 16 to spray the fabric at intervals onto the inner walls of the expansion member 4 and the recess 8 through the drive device 21 to form a sealing layer 5 and a guide layer 6 while the fabric is being conveyed.

[0055] Step 8: Heat transfer the waterproof layer 35 onto the end face of the sunscreen layer 2 away from the inner layer 1;

[0056] Step 9: Simultaneously, several arrays of ventilation holes 3 are opened at the bottom of the recesses 8 on both the waterproof layer 35 and the sun protection layer 2;

[0057] Step 10: Sew the inner layer 1 and the sun protection layer 2 together.
