Problems solved by technology

However, there is a problem in disperse dye transfer printing: polyester oligomers (mainly cyclic terpolymers) have good compatibility with polyester fibers and are not easy to wash off
However, for polyester-cotton transfer printing fabrics, due to the short sublimation time at high temperature during transfer printing, the impact of the migration of oligomers on the feel of polyester-cotton has been ignored. So far, there is no corresponding removal of oligomers to improve the feel of polyester-cotton interwoven printing fabrics. method

Abstract

The invention discloses a finishing method capable of improving the hand feeling of a polyester-cotton interwoven jacquard transfer-printed fabric. The method comprises the following steps: pre-treatment refining; bleaching; whitening; transfer printing with disperse dyes; alkaline reduction clearing; and softening and shaping. The procedure of alkaline reduction clearing is to carry out cleaning in a finishing liquid with a temperature of 25 to 35 DEG C for 28 to 32 min, wherein in the finishing liquid, the concentration of ammonia is 4 to 6 g / L, the concentration of a nonionic emulsification dispersant is 4 to 6 g / L, and the concentration of an oligomer dispersant is 2 to 5 g / L. According to the invention, solubility of oligomer in water is improved through complex formulation of an aqueous ammonia solution and the nonionic emulsification dispersant, so roughness of the fabric can be effectively improved and soft and smooth hand feeling can be obtained in transfer printing.

Description

technical field [0001] The invention relates to a finishing method for improving the hand feeling of polyester-cotton interwoven jacquard transfer printing fabric, belonging to the technical field of dyeing and finishing. Background technique [0002] The printing of polyester-cotton interwoven or blended jacquard fabrics has different coloring properties due to the different physical and chemical properties of polyester and cotton fibers. [0003] At present, about 60% to 70% of polyester-cotton blended fabrics at home and abroad use pigment printing technology. Although pigment printing has intuitive color and simple process, for deep and thick colors and large-area patterns, the hand feeling after printing is relatively hard, and friction and The scrubbing fastness and air permeability are poor, which cannot fully meet consumer demand. [0004] Polyester-cotton interwoven products mostly use disperse / reactive same paste printing, but since the currently used reactive dye...
