Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fabric weaving, in particular to a multi-layered fitted channel cloth and a preparation process thereof. BACKGROUND

[0002] Down fabric has been widely used in the field of home textiles and clothing due to its excellent light and warm properties, and there are various types of products. However, the traditional down fabric often faces a problem in the sewing process: the use of sewing needles and threads can easily cause the down to escape from the needle holes. At the same time, the sewing thread itself also becomes the main path for the down to escape, enter water or be breathable in daily use, which seriously affects the manufacturing and user experience of high-quality down fabric products. In order to solve this problem, the existing technology improves the traditional process by using a method of first dividing the down and then combining the inner and outer layers of the fabric during weaving. This method makes the fabric present a channel shape, with no needle hole gap on the outside, which is not only flat but also beautiful. However, although the yarns of the surface layer and the inner layer in the current technology are consistent in material and hand feeling, when the inner layer comes into contact with the human skin, it often produces a cold feeling, which reduces the comfort of wearing. In addition, the yarns currently used rely on non-renewable petroleum resources, which conflicts with the current social concept of environmental protection and low carbon development. At the same time, in the waterproof finishing process of the fabric, the commonly used C6 / C8 waterproof agent is not only difficult to degrade, but also may produce harmful substances in its production process, posing a potential threat to the environment.

[0010] The sixth technical solution is based on the first technical solution, wherein in the dyeing process, after adjusting the pH value of dyeing by acetic acid, the required disperse dye and acid leveling agent are added, the temperature is raised to 130℃ at a temperature raising rate of 1.5℃ / min, and then the temperature is kept for 40min at this temperature, then the temperature is lowered to 80℃ at a temperature lowering rate of 1.5℃ / min, the liquid is discharged, and the cloth is washed clean before being taken out.

[0011] The seventh technical solution is based on the first technical solution, wherein in the waterproof finishing process, after the dyed channel cloth is subjected to drying and setting treatment, a bio-based waterproof finishing agent is finished on the surface of the fabric by using the padding process; wherein the amount of bio-based waterproof agent is 35g / L, the liquid retention rate is kept at 60%, the treatment temperature is set to 165℃, and the speed is 25m / min.

[0013] The ninth technical solution is based on any one of the first to eighth technical solutions for producing a multi-layered bonded channel cloth.

[0014] From the above description of the present application, the present application has the following beneficial effects compared with the prior art:

[0015] In the first technical solution and related embodiments, by using renewable polyester fibers and their covering yarns as raw materials, not only the channel cloth has strength and wear resistance, but also embodies the concept of environmental protection and sustainable development. By combining a layer of fleece cloth on the inside of the channel cloth, it not only ensures the elasticity of the fabric, but also gives the channel cloth better warmth performance, further improving the comfort of the channel cloth when in contact with the skin, and enhancing the user's wearing experience.

[0016] In the second technical solution and related embodiments, the preparation process of this multi-layered channel cloth realizes efficient, environmentally friendly, stable and high-quality production effects by using a multi-arm loom, renewable polyester fibers and polyester-covered spandex covering yarns. The multi-arm loom can produce various complex fabric patterns with high efficiency, precision and powerful features, ensuring the stability and beauty of the channel cloth structure. Using renewable polyester fibers as warp yarns not only meets the development concept of environmental protection and low carbon, but also has high strength, wear resistance, durability, good air permeability and bright color, etc. This makes the prepared channel cloth not only have excellent physical properties, but also meet the environmental protection requirements. The weft yarns use renewable polyester fiber-covered spandex covering yarns, which combines the advantages of polyester and spandex. Polyester provides good strength and durability, while spandex gives the yarn excellent elasticity and comfort. In addition, the covering yarn structure of spandex enhances the color fastness and stability of the yarn, so that the channel cloth is not easy to fade and deform during use.

[0017] In the third technical solution and related embodiments, this is one of the embodiments, which can prepare a multi-layer channel cloth with excellent warmth performance, comfort and durability by reasonably setting the linear density of warp and weft yarns and the density of warp and weft directions. The warp yarns have a linear density of 30D / 36, which ensures that the channel cloth has sufficient strength and stability in the longitudinal direction (warp direction). This linear density allows the warp yarns to be evenly distributed, effectively supporting the structure of the entire fabric and preventing stretching or deformation during use. The weft yarns have a linear density of 35D / 144 and a composite structure of 20D spandex, which not only enhances the strength and elasticity of the weft direction, but also makes the channel cloth have excellent performance in the transverse direction (weft direction). This composite yarn structure can fully utilize the advantages of polyester fiber and spandex, ensuring the durability of the fabric and providing good elasticity and comfort. The setting of the warp density of 196 / cm and the weft density of 170 / cm makes the fabric structure more compact, effectively preventing heat loss and external cold air intrusion, thereby improving the warmth performance of the channel cloth.

[0018] In the fourth technical solution and related embodiments, this is one of the embodiments. By reasonably setting the linear density of warp and weft yarns and the density of warp and weft directions, a multi-layer channel cloth with excellent warmth performance, comfort and durability can be prepared. The linear density of warp yarns is set to 30D / 48, and the number of warp yarns per centimeter is increased compared to the previous embodiment. This design makes the channel cloth more dense in the warp direction, enhancing the longitudinal support and stability of the cloth. In addition, due to the increase in the linear density of the spandex in the weft direction, the elasticity and recovery performance of the cloth are further improved.

[0019] In the fifth technical solution and related embodiments, the purpose of the pre-treatment link is to remove the oil on the surface of the channel cloth, ensuring that subsequent dyeing and waterproof finishing processes can proceed smoothly. Chelating dispersants can effectively disperse and remove impurities in the fiber, and oil refining agents can deeply clean the oil, while liquid alkali can adjust the pH value and enhance the cleaning effect.

[0020] In the sixth technical solution and related embodiments, the dyeing process adjusts the pH value of the dyeing solution by using acetic acid, ensuring that the dye can react with the channel cloth fiber in the best environment, thereby achieving uniform and bright dyeing effect. After adding disperse dyes and acid leveling agents, the temperature rising rate and holding time are controlled to ensure that the dye can fully penetrate and uniformly adhere to the channel cloth fiber. Subsequently, the temperature is reduced to 80℃ at the same cooling rate, so that the dye molecules are better fixed inside the fiber, improving the fastness and durability of the dyeing.

[0021] In the seventh technical solution and related embodiments, in the waterproof finishing process, the dip padding process is used to evenly finish the bio-based waterproof finishing agent on the surface of the channel cloth. As an environmentally friendly material, bio-based waterproof agent not only has excellent waterproof performance, but also has good biodegradability, meeting the requirements of green development.

[0022] In the eighth technical solution and related embodiments, in the compounding process, by accurately controlling the parameters such as gluing gap, lamination pressure, glue temperature, gluing pressure, winding pressure and engraved roller glue coverage, the tight lamination between the channel cloth and the polyester fleece cloth is realized, ensuring the stability and uniformity of the composite layer. The polyester fleece cloth has good warmth due to its fiber structure characteristics, and the channel cloth has a double-layer cloth design and an intermediate channel, so that heat is more easily retained inside the cloth. Therefore, the compounding of the two makes the product perform well in terms of warmth. The polyester fleece cloth has a soft and comfortable touch, providing users with a better wearing experience.

[0023] In the ninth technical solution and related embodiments, the multi-layer channel cloth uses renewable polyester fiber and its wrapping yarn as raw materials, which not only ensures the strength and wear resistance of the product, but also embodies the concept of environmental protection and sustainable development. At the same time, in order to further enhance the functionality of the channel cloth, a biological-based waterproof agent is used for waterproof finishing. This waterproof agent is not only safe and environmentally friendly, but also effectively enhances the durability of the fabric during use. By using composite polyester fleece cloth, the warmth retention performance of the product is further enhanced, and the comfort when in contact with the skin is improved. DETAILED DESCRIPTION

[0035] A multi-layered channel cloth is produced by the above-mentioned multi-layered channel cloth production process. The multi-layered channel cloth uses renewable polyester fiber and its covering yarn as raw materials, which not only ensures the strength and wear resistance of the product, but also embodies the concept of environmental protection and sustainable development. At the same time, in order to further enhance the functionality of the channel cloth, a biological-based waterproofing agent is used for waterproofing. This waterproofing agent is not only safe and environmentally friendly, but also effectively enhances the durability of the fabric during use. By combining polyester fleece cloth, the warmth retention performance of the product is further enhanced, and the comfort when in contact with the skin is improved.

[0036] Example one

[0037] In the weaving process, the linear density of the warp yarn is 30D / 36, the linear density of the weft yarn is 35D / 144 and 20D spandex, the warp density is 196 / cm, and the weft density is 170 / cm.

[0038] The pretreatment process is as follows: at a temperature of 90℃, use 2g / L of chelating dispersant 604, 5g / L of refining oil removal agent M-1016NT, and 10g / L of liquid alkali (concentration of 30%), at a speed of 50m / min. The dyeing process is by adjusting the pH value of the dyeing with acetic acid, adding the required disperse dyes and acid leveling agent 702B. Then, increase the temperature to 130℃ at a rate of 1.5℃ / min, and keep it for 40 minutes. Then, decrease the temperature to 80℃ at a rate of 1.5℃ / min, then drain, wash until clean, and then take out the cloth.

[0039] In terms of waterproofing process, use 35g / L of biological-based waterproofing agent 804 to ensure that the liquid rate reaches 60%, and process at a temperature of 165℃ and a speed of 25m / min. The composite process is to composite the waterproofed channel cloth with polyester fleece cloth. The polyester fleece cloth is 75D / 72F, with a weight of 120 grams per square meter, and is made by using the shake pile process. In the composite process, DJ1102B hot melt adhesive is selected, with a glue gap of 0.4mm, a bonding pressure of 4Kg, a glue temperature of 108℃, a glue pressure of 25kg, and a winding pressure of 8kg. The glue coverage of the engraved roller is 50%, and the speed is 5m / min. After the composite is completed, it is kept in a constant temperature and humidity workshop for 48 hours.

[0040] After testing, the fabric has a <20 root anti-pilling performance, a ≥4 level water repellency performance, a ≥20,000 turn abrasion resistance (Martin Dale abrasion tester), and a total gram weight of 313gsm.

In the composite process, the polyester fleece fabric specification is 75D / 144F, the weight per square meter is 140 grams, and the recycled yarn chenille is 100% PES.

[0044] Compared with Example One, the number of warp yarns per centimeter is increased, making the channel cloth more dense in the warp direction, enhancing the longitudinal support and stability of the cloth. In addition, due to the increase in the linear density of spandex in the weft direction, the elasticity and recovery performance of the cloth are further improved. The number of fibers of the polyester fleece fabric is more, making the fleece cloth more delicate and better in warmth retention performance.

[0045] Tested, the anti-pilling performance of this fabric is <20, the anti-splashing performance is ≥4 levels, the wear resistance is ≥20,000 turns (Martin Dale wear tester test), and the total gram weight is 327gsm.
