Description

Technical Field

[0001] This invention belongs to the field of fabrics, and in particular relates to a method for preparing a continuous cooling fabric. Background Technology

[0002] Fabrics and apparel with cooling and quick-drying properties are in high demand in summer and have always been a key feature promoted by various sports brands in their summer clothing. With the rapid development of the domestic sports market and the increasing demands of sports enthusiasts for the functionality of clothing, the development of sports fibers and fabrics with ultimate cooling and quick-drying properties has become a hot topic and focus in the industry.

[0003] Nylon is soft, comfortable, and has excellent cooling properties. In the past two years, many sports brands, including NIKE, UNDER ARMOUR, Anta, and Li-Ning, have gradually started using nylon as a sports fabric for summer wear. However, it is difficult to further improve the cooling effect of nylon through spinning additives and finishing agents. Moreover, nylon has poor quick-drying properties, making it difficult for sweat to be expelled and evaporated quickly during exercise. This causes nylon fabrics to feel stuffy and sticky during exercise, thus limiting the development of nylon sports fabrics.

[0004] Chinese patent CN111560659A discloses a functional recycled nylon 6 fiber, its preparation method, and fabric. The invention mainly involves preparing nylon 6 spinning masterbatch by recycling nylon 6 waste, and then producing flat recycled nylon yarn through a shaped spinneret. The shaped cross-section of the yarn and fabric can change the contact form between the fiber surface and water molecules, thereby improving the performance of the final fabric in terms of continuous cooling wearing experience.

[0005] However, the Qmax values ​​of currently produced fabrics are mostly below 0.22. Furthermore, due to the high moisture regain of nylon (around 4.5%), the fabric is very smooth. During exercise, when sweat is produced, the fabric absorbs moisture, causing blockages in the pores between fibers and yarns, leading to a stuffy feeling and preventing sweat from evaporating quickly. The fabric adheres to the skin, significantly impacting the exercise experience. Therefore, how to further improve the cooling and quick-drying properties of nylon fabrics has become a pressing technical challenge for the industry. Summary of the Invention

[0006] The purpose of this invention is to propose a method for preparing a continuous cooling fabric. The fabric prepared has a continuous cooling function, an ultra-high Qmax value, and a continuous low-temperature effect, far exceeding national standards.

[0007] To achieve this objective, the present invention adopts the following technical solution: This invention provides a method for preparing a continuous cooling fabric, comprising the following steps: S1: weaving, using nylon and spandex as raw materials to weave a greige fabric; S2: dyeing, using acid dyes to dye the greige fabric woven in step S1 at 95-105℃; S3: finishing, drying the dyed greige fabric in step S2 at 155-165℃, adding 1-3wt% of a moisture-wicking agent during the drying process, and then finishing the finished product at 130-160℃, adding 5-7wt% of a cooling finishing agent during the finishing process, and obtaining the continuous cooling fabric after finishing.

[0008] Furthermore, the nylon is made of fully dull yarn, and the nylon is covered on the surface of the spandex to form a fabric through knitting, so that the nylon is on the front side of the fabric and the spandex is on the back side of the fabric.

[0009] Preferably, in step S1, two guide sections, GB1 and GB2, are used for weaving; wherein guide section GB1 is made of nylon with a yarn length of 850-900 cN, and is threaded in a full-thread manner; guide section GB2 is made of spandex with a yarn length of 450-500 cN, and is threaded in a 1-thread-1-loop and 2-thread-1-loop manner; the weight of the finished fabric is 180-190 g / m². 2 The fabric structure is jacquard.

[0010] Further, step S2 dyeing specifically includes the following steps: Water is added to the dyeing vat at a liquor ratio of 1:(18-22). After confirming the water level, the greige fabric is placed into the vat. Then, acid dye is added slowly over 25-35 minutes. After 4-6 minutes of circulation, the vat is heated to 55-65℃ at a heating rate of 0.4-0.6℃ / min. After holding at this temperature for 8-12 minutes, the vat is heated to 78-83℃ at a heating rate of 0.4-0.6℃ / min. After 8-12 minutes, the vat is heated to 95-105℃ at a heating rate of 0.8-1.2℃ / min. After holding at this temperature for 43-48 minutes, the water in the dyeing vat is cooled to 67-73℃ at a cooling rate of 1.3-1.7℃ / min. A sample is taken for color matching. After confirming the color, the water is drained.

[0011] Preferably, after draining, at least three cleaning cycles are performed: For the first cleaning, water is added to the tank at a liquor ratio of 1:(18-22), and 0.4-0.6 G / L of cleaning agent is added. The tank is cleaned at 38-42°C for 18-22 minutes, and then drained. For the second cleaning, water is added to the tank at a liquor ratio of 1:(18-22), and 2.8-3.2 G / L of acidic color-fixing agent is added. The tank is cleaned at 38-42°C for 18-22 minutes to fix the color, and then drained. For the third cleaning, water is added to the tank at a liquor ratio of 1:(18-22), and 0.4-0.6 G / L of soap powder is added. The tank is cleaned at 38-42°C for 18-22 minutes to fix the color, and then drained.

[0012] Preferably, before step S2, the process further includes: inspecting the greige fabric woven in step S1, and after inspection, washing it in a washing machine at 83-86°C and 18-22 m / min, adding spandex degreasing agent and chelating agent in the washing machine, and then transferring it to the greige fabric for shaping after washing.

[0013] Preferably, the amount of spandex degreasing agent added is 1.5-2.5% of the mass of acid dye; the amount of chelating agent added is 0.3-0.7% of the mass of acid dye.

[0014] Preferably, the fabric is heated by steam and a fabric setting machine with 8 independent temperature control chambers is used. The temperature of each chamber is set to 170 / 180 / 190 / 190 / 190 / 190 / 190 / 170 / 150℃ respectively, and the machine speed is 18-22 meters / min.

[0015] Preferably, the acid dye comprises the following components by weight of the greige fabric: Acid Navy Blue NFS-H 0.5-0.65%; Acid Red HF 0.170-0.185%; Acid Brilliant Blue SF-GWN 0.080-0.090%.

[0016] Preferably, during the dyeing process in step S2, auxiliaries are added simultaneously with the acid dye. The auxiliaries include the following raw materials: 0.4-0.6 G / L glacial acetic acid-HAC; 0.1-0.3 G / L spandex degreasing agent; 0.4-0.6 G / L bath conditioner; and 0.8-1.2 G / L acid leveling agent.

[0017] The beneficial effects of this invention are as follows: 1. Using nylon and spandex raw materials, and through the process of this invention, an ice-feeling agent is added during the dyeing and finishing process to form a new type of unique fabric with continuous ice-feeling nylon elasticity. After testing, this fabric has an ultra-high Qmax value and continuous low-temperature effect, which is superior to the national standard.

[0018] 2. The present invention forms a fabric by knitting nylon over spandex, with the nylon matte yarn on the front side of the fabric. This gives the fabric good elasticity and breathability, making it comfortable and pleasant to the touch when worn.

[0019] 3. In the production process of this invention, the yarn lengths of the two types of yarn are controlled to ensure that the fully dull yarn is stacked on the surface of the elastic yarn, which can prevent defects such as yarn flipping, yarn breakage, and yarn dropping.
