Problems solved by technology

[0003] The moso bamboo polyester fabric woven with moso bamboo yarn blended with wool fiber, bamboo fiber and polyester fiber has the functions of anti-mildew, anti-moth, antibacterial and antibacterial, deodorant, anti-ultraviolet and natural health care. Trendy, but because of the addition of bamboo fiber, the dyeing and finishing process of this fabric is different from the usual polyester-viscose-wool blended fabric
[0004] Bamboo fiber is cellulose fiber, which can be dyed with direct dyes or reactive dyes under neutral or alkaline conditions, while wool is suitable for acid dyeing, but the general high-temperature two-bath dyeing method is affected by dyes, auxiliary agents and other process parameters. Influenced by factors, it has disadvantages such as difficult to control color difference, uneven coloring, easy to produce color flower or floating color, low color fastness, etc.
[0005] In addition, the finishing process of polyester-viscose-wool blended fabrics in the past is used to finish the moso bamboo polyester fabric, and the finished product is not smooth enough, the cloth surface is not flexible, and the characteristics of softness and moisture absorption of bamboo fiber products cannot be maintained; moreover, the rigidity of bamboo fiber is relatively high. Large, wool-blend fabrics tend to crease during finishing and cannot be easily removed

Abstract

The invention discloses a dyeing and post-finishing process of woolen bamboo polyester fabrics, which includes steps: firstly joining ends of gray fabrics, namely using a splicer to joining the ends of the gray fabrics; secondly, singeing, brushing and shearing; thirdly, desizing, boiling off and using an open-width washing machine for scouring; fourthly, preshrinking for shaping; fifthly, using the high-temperature two-bath method for dyeing, namely using reactive dye of CibacronFN cotton at 60-65 DGE C for 50-60 minutes first, and then using acid dye to dye at 130-135 DEG C for 40-50 minutes; sixthly, soft finish shaping, namely performing soft finish shaping twice; seventhly, decatizing for shaping, wherein the internal pressure of a decatizing machine is 0.5-1.2bar, and the cold drawing time is 1-1.5 minutes; and eighthly, light decatizing for shaping, wherein the internal pressure of a decatizing machine is 0.4-0.5bar, and the cold drawing time is 1-1.5 minutes. By the dyeing and post-finishing process, loose colour of fabrics can be reduced, color fastness can be guaranteed, coloring is uniform, the characteristics of bamboo fiber products such as softness and moisture absorption are kept, hand touch is improved and woolen surfaces of the fabrics are flat, smooth and clear in texture.

Description

technical field [0001] The invention relates to a dyeing and finishing process of textile fabrics, in particular to a dyeing and finishing process of moso bamboo polyester fabrics. Background technique [0002] Bamboo fiber is a fiber material extracted from bamboo. It is the fifth largest natural fiber after cotton, hemp, wool and silk. It has good environmental protection, air permeability, resilience, water absorption and skin-friendly properties. Clothing made of it is called "human second skin". Blending other fibers in bamboo fiber can make it not only have the function of bamboo fiber, but also increase other functions. [0003] The moso bamboo polyester fabric woven with moso bamboo yarn blended with wool fiber, bamboo fiber and polyester fiber has the functions of anti-mildew, anti-moth, antibacterial and antibacterial, deodorant, anti-ultraviolet and natural health care. However, due to the addition of bamboo fiber, the dyeing and finishing process of this fabric...
