Abstract

The invention relates to a dyeing method for electrospinning functional textiles. The method includes: padding the electrostatic spinning cotton fabric with antibacterial function in a treatment solution, then stacking and steaming; placing it in brilliant blue dye for dyeing. The method can slow down the instant dyeing rate of the dye reactive brilliant blue 19 and reduce the probability of dyeing.

Description

technical field [0001] The invention belongs to the technical field of electrospinning textiles, and particularly relates to a dyeing method for electrospinning functional textiles. Background technique [0002] Electrospun cotton fabrics, due to the introduction of sub-micron acrylic fibers with antibacterial function during the spinning process, lead to inconsistent uniformity of finished yarns. In the pre-treatment process of the conventional overflow cylinder, the alkali in the yarn area after electrospinning is relatively difficult to clean, resulting in a high local pH value. [0003] C.I. Reactive Blue 19, Chinese name Reactive Brilliant Blue KN-R is a reactive dye, the structural formula is as follows: [0004] [0005] The molecular formula is C 22 H 16 N 2 Na 2 O 11 S 3 , with a molecular weight of 626, is a vinylsulfone reactive dye. Due to its bright color, other reactive dyes cannot replace it, so when dyeing brilliant blue, sky blue and other colors,...
