Abstract

The invention relates to a dyeing method of an electrostatic spinning functional textile. The method comprises the following steps: padding an electrostatic spinning cotton fabric with an antibacterial function in a treating fluid, and then stacking and steaming, and dyeing in a brilliant blue dye. According to the method, the instantaneous dye-uptake of the reactive brilliant blue 19 can be slowed down, and the dyeing probability is reduced.

Description

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