Description

Technical Field

[0001] This application relates to the field of textile dyeing and finishing, and more specifically, to an outdoor sports fabric and its dyeing and finishing process. Background Technology

[0002] PBT fiber is short for polybutylene terephthalate fiber. It is a linear polymer obtained by melt spinning from the condensation polymerization of high-purity terephthalic acid (PTA) or dimethyl terephthalate (DMT) with 1,4-butanediol, and belongs to the polyester fiber family. It possesses excellent high-temperature resistance, moisture resistance, oil resistance, good electrical insulation, chemical corrosion resistance, fast molding, easy molding, and low moisture absorption. It is a new type of engineering plastic with excellent comprehensive performance and is widely used in various fields such as automobiles, machinery, instruments, electronics, home appliances, textiles, and civilian products. Furthermore, due to PBT's high strength, good shape stability, excellent wet shape stability, and good chlorine resistance, it has become an ideal fiber for weaving swimwear, skiwear, training clothing, etc. Moreover, due to PBT's excellent bulk and crimp, there is great potential for developing various elastic fabrics using PBT elastic yarns, and for producing various woolen fabrics by blending PBT wool-like staple fibers with wool.

[0003] However, PBT textiles are exposed to external factors such as light, washing, ironing, perspiration, friction, and chemicals during use. Due to the low colorfastness of existing PBT fabrics, color fading is a common problem. Summary of the Invention

[0004] To address the problem of low color fastness of PBT textiles in related technologies, this application provides an outdoor sports fabric and its dyeing and finishing method.

[0005] This application provides an outdoor sports fabric, including a base fabric and an outer fabric, which are bonded together by hot melt adhesive. The base fabric is made of 60% 75D / 96F DTY + 40% 55D / 24F PBT, and the outer fabric is made of 60% 50D / 72F DTY + 40% 50D / 36F DTY.

[0006] The base fabric and the outer fabric described in this application are bonded together with hot melt adhesive, which effectively ensures the softness of the fabric. Furthermore, this application limits the raw materials of the base fabric and the outer fabric, so that the fabric has high strength and stability.

[0007] Preferably, the base fabric is woven using a two-comb warp plain weave, and the face fabric is woven using a 30-inch towel knitting machine and a 208-needle towel knitting machine, using a terry weave.

[0008] This application defines the structure and weaving method of the base fabric and the outer fabric, combining the softness and comfort of knitted fabric with the structure and crispness of woven fabric, so that the fabric has high comfort and at the same time ensures that the fabric has higher performance.

[0009] Preferably, the hot melt adhesive is a polyurethane single-component reactive hot melt adhesive RHM9000, and the hot melt adhesive bonding process includes the following steps: after the base fabric and the top fabric are bonded together, they are placed in a constant temperature room at 25-30℃ and left to stand for 100-140 hours to obtain the outdoor sports fabric.

[0010] This application defines the type of hot melt adhesive and also defines the temperature and time during the hot melt adhesive bonding process to ensure that the base fabric and the face fabric can be stably bonded together, while avoiding damage to the base fabric and the face fabric during the hot melt adhesive bonding process.

[0011] Preferably, the dyeing and finishing process of the base fabric includes the following steps in sequence: base fabric refining, base fabric dyeing, base fabric drying, base fabric warp knitting and napping, base fabric shearing and base fabric finishing.

[0012] This application effectively improves the color fastness of the base fabric by limiting the dyeing and finishing process of the base fabric, avoiding color fading during subsequent bonding with the face fabric, and effectively ensuring the quality and specification stability of the fabric.

[0013] Preferably, the auxiliaries used in the dyeing process of the base fabric include NICCA SUNSOLT 7000Z leveling agent and NICCA SUNSOLT SN-7500.

[0014] This application effectively improves the coloring effect of the base fabric during the dyeing process by limiting the types of auxiliaries used in the dyeing process, and avoids the dye from peeling off the base fabric during use.

[0015] Preferably, the drying temperature of the base fabric is 100-200℃, the base fabric moving speed is 20-30m / min, and the additives used are methyl silicone oil emulsion TranSoft TF-4949 and multifunctional finishing agent TF-406F.

[0016] This application ensures that the base fabric has extremely high color fastness by limiting the drying temperature, the movement speed of the base fabric, and the additives used.

[0017] Preferably, the temperature for shaping the finished base fabric is 100-200℃, and the base fabric moving speed is 15-25m / min.

[0018] This application ensures that the base fabric has extremely high color fastness by limiting the temperature for shaping the finished base fabric and the speed at which the base fabric moves.

[0019] Preferably, the dyeing and finishing process of the fabric includes the following steps in sequence: fabric shrinkage, fabric dyeing, fabric high-temperature setting, fabric rewashing, and fabric finished product setting.

[0020] This application also defines the dyeing and finishing process of the fabric to ensure that the fabric has high color fastness and avoid the base fabric from being stained with dye due to the color of the fabric fading, thereby effectively improving the overall color fastness of the fabric.

[0021] Preferably, the temperature of the fabric shrinkage is 80-90℃, the fabric moving speed is 20-25m / min, and the additives used are SUNMORL WR-8600 and chelating dispersant HT-67.

[0022] This application can ensure the stability of the fabric's quality and specifications by limiting the temperature and speed of the fabric shrinkage process.

[0023] Preferably, the dyeing temperature of the fabric is 120-140℃, the dyeing time is 50-70 minutes, and the auxiliaries used are high-efficiency degreasing agent CPA, NICCA SUNSOLT SN-7500, and... E3-SAVE polyester process enhancer.

[0024] This application ensures that the fabric has good colorfastness by limiting the dyeing temperature, time and the auxiliaries used in the dyeing process.

[0025] In summary, this application has the following beneficial effects: 1. This application combines knitted and woven fabrics, and limits the raw materials of the base fabric and the outer fabric, effectively ensuring the softness and comfort of the fabric described in this application, while ensuring that the fabric has a high degree of structure and crispness.

[0026] 2. This application defines the dyeing and finishing process of the base fabric and the outer fabric, and also defines the specific treatment agents for the base fabric and the outer fabric in the dyeing and finishing process, which effectively improves the color fastness of the base fabric and the outer fabric, avoids color fading of the base fabric or the outer fabric, and makes the fabric have high color fastness. Treating white base fabric with the dyeing and finishing process described in this application can effectively improve the white fastness of the fabric. Detailed Implementation
