Description

Technical Field

[0001] The invention relates to the technical field of cloth processing, and in particular to a finishing process of a mint natural bamboo cotton double-layer cloth. Background Art

[0002] Mint bamboo cotton fabric is made by extracting active ingredients from natural mint, blending it with bamboo pulp, and then blending it with 30% 40S cotton yarn to weave a double-layer fabric. Since mint and bamboo fibers have natural antibacterial effects, they feel soft, bright and drapey, and have good moisture absorption and breathability, they are high-end clothing fabrics for infants and young children.

[0003] However, in the prior art, since mint bamboo cotton fabric contains 30% cotton, if the traditional alkali desizing, scouring and high-temperature bleaching with hydrogen peroxide are adopted, the mint bamboo fiber will be damaged, the strength will be reduced, holes will be generated and other problems will occur. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention solves the technical problems by adopting a technical solution: a finishing process for a mint bamboo cotton double-layer cloth, comprising the following finishing steps: Step 1: Determine the raw materials: Select mint bamboo cotton double cloth as the pre-finishing fabric; Step 2, singeing and desizing: singe the pre-finished fabric in step 1, and after singeing, extinguish the fire by padding with amylase and stacking for desizing; Step 3, bleaching treatment: the fabric that has been desized and stacked in step 2 is washed with high-temperature water, then bleached in a padding bleaching solution, and then steamed and stacked; Step 4: Dyeing: The fabric bleached in step 3 is dyed with reactive dyes; computer printing can also be used to dye the fabric with the desired color according to demand; Step 5: Softening treatment: Add a soft silicone softening finishing agent to the dyed fabric in step 4 for softening; Step 6: Antibacterial treatment: Soak the fabric softened in step 5 in an aqueous solution containing an antibacterial agent and an auxiliary agent; Step 7: Pre-shrinking treatment: Put the fabric that has been treated with antibacterial agents in step 6 into a pre-shrinking machine, and pre-shrink it by squeezing the felt in the pre-shrinking machine; Step 8: Inspection and packaging: The pre-shrunk fabric obtained in step 7 is cleaned, dried and inspected, and after the inspection, the qualified fabric is packaged, and the fabric finishing is completed.

[0005] The present invention is further configured as follows: the cloth specification width in the step 1 is 180 cm, 40 yarns are used, and the cloth structure is a mint bamboo cotton double cloth with a warp density of 106 strands / inch and a weft density of 92 strands / inch.

[0006] The present invention is further configured as follows: the amylase in step 2 is a wide-temperature starch desizing enzyme, the dosage is 4 g / l, the stacking desizing adopts room temperature stacking, and the room temperature stacking time is 12 hours. The wide-temperature starch desizing enzyme is used to desize the fabric at room temperature to remove the size applied to the fabric during the weaving process, the desizing effect is good, no damage is caused to the fabric, and it is ecological, environmentally friendly and energy-saving.

[0007] The present invention is further configured as follows: the bleaching liquid in step three is a low-temperature scouring agent, the dosage is 3g / l, the pH is 10, the steam stacking temperature is 80°C, and the steam stacking time is 65min. The low-temperature scouring agent is composed of hydrogen peroxide and a multifunctional scouring enzyme, the hydrogen peroxide dosage is 5-6g / l, and the multifunctional scouring enzyme dosage is 15g / l. The use of a multifunctional scouring enzyme can effectively remove cottonseed hulls and improve whiteness, and the use of a low-temperature scouring agent can reduce the scouring temperature, thereby reducing damage to mint and bamboo fiber without affecting the whiteness of the fabric. Since mint and bamboo fiber are not alkali-resistant, soda ash is used to adjust the pH.

[0008] The present invention is further configured as follows: the pressure of the pre-shrinkage treatment in step seven is 10 kg / cm2 and the temperature is 80° C. In conventional pre-shrinkage, the tension is appropriately relaxed, and the size and shape of the fabric are stabilized by heating and stretching.

[0009] The present invention is further configured as follows: the antibacterial agent in step 6 is a silver silica antibacterial agent, and the auxiliary agent is a cross-linking agent and a dispersant. Considering the characteristics of mint as a plant, the silver silica antibacterial agent is added to ensure that the antibacterial agent has good antibacterial effect and compatibility with fabrics. The auxiliary agent is added to enhance the stability and durability of the antibacterial agent. The cross-linking agent can improve the strength and elasticity of the auxiliary agent, reduce the possibility of chain breaking, and improve the waterproof, oil-proof and anti-fouling effects. The introduction of the dispersant can disperse the fiber clumps, make the textile texture more delicate, and improve the quality.

[0010] The beneficial effects of the present invention are as follows: The invention adopts a wide temperature starch desizing enzyme to desize the fabric at room temperature during the desizing process, has good desizing effect, does not cause any damage to the fabric, is eco-friendly and energy-saving; adopts a multifunctional scouring enzyme to effectively remove cottonseed hulls and improve whiteness during the bleaching process, adopts a low temperature scouring agent to reduce the scouring temperature, and reduces damage to mint and bamboo fiber without affecting the whiteness of the fabric. Since mint and bamboo fiber are not alkali-resistant, soda ash is used to adjust the pH, and a silver silica antibacterial agent is added according to the characteristics of mint to ensure that the antibacterial agent has a good antibacterial effect and compatibility with the fabric.
