Abstract

The invention provides a dyeing and finishing method for tencel / bamboo pulp fiber blended fabric. Gray fabric is sequentially subjected to singeing, enzyme rolling and cold piling, washing, cold piling, mercerizing, tentering and whitening, printing, ageing, washing, softening and shaping, calendaring and pre-shrinking, and then the tencel / bamboo pulp fiber blended fabric is obtained, wherein the caustic soda concentration in the mercerizing process ranges from 80 g / L to 90 g / L. The dyeing and finishing method is mainly used for dyeing and finishing the tencel / bamboo pulp fiber blended fabric, and warp and weft of the fabric are tencel / bamboo pulp fiber blended yarn. The shrinkage rate of the obtained tencel / bamboo pulp fiber blended fabric is within the range from +2% to -4%, and the fabric is soft in hand feeling, smooth in fabric cover and free of deformation.

Description

technical field [0001] The invention belongs to the technical field of textile dyeing and finishing, and in particular relates to a method for dyeing and finishing a Tencel / bamboo pulp fiber blended fabric. Background technique [0002] Tencel and viscose fibers are both types of regenerated cellulose fibers. However, due to the different processing methods of tencel and viscose fibers, the properties of the fibers are quite different. Bamboo pulp viscose fiber is a kind of viscose fiber, which is prepared from bamboo pulp through wet spinning process of viscose fiber. Therefore, bamboo pulp fiber not only has the basic properties of viscose fiber, but also has the antibacterial properties of bamboo fiber. [0003] Regenerated cellulose fiber, especially viscose fiber, has low dry and wet breaking strength and crystallinity, and high breaking elongation. During the printing and dyeing process, there will be water and external force on the fabric. A large number of hydroxy...
