Abstract

The invention discloses a one-bath dyeing and anti-mosquito finishing method of aramid fiber disperse dye, belonging to the technical field of the dyeing and after finishing of polyamide fiber or textile. According to the invention, diethyltoluamide is used as a disperse dye aramid fiber dyeing carrier to promote the dyeing of the disperse dye aramid fiber textile and realize certain anti-mosquito function of the aramid fiber textile. The process flow comprises the steps of aramid fiber pretreatment, one-bath dyeing, anti-mosquito finishing and reduction clearing. Through the dyeing and the anti-mosquito finishing aramid fiber provided by the invention, the aramid fiber can obtain relatively high dye uptake and good dyeing effect as well as certain anti-mosquito ability. The method disclosed by the invention has wide applicability, simple technology, low treatment cost and high industrial application value.

Description

technical field [0001] The invention belongs to the technical field of polyamide fiber or fabric dyeing and finishing, and in particular relates to a method for dyeing para-aramid and para-aramid fiber or fabric and finishing in the same bath for mosquito repellent. Background technique [0002] The full name of aramid fiber is aromatic polyamide fiber. It is a synthetic fiber made of aromatic compound as raw material through polycondensation liquid crystal spinning. It has excellent physical and mechanical properties, thermal oxidation and resistance due to its rigid chain structure and good regularity Combustibility and excellent electrical properties, etc., are widely used in national defense, fire protection, automobiles, aerospace and other fields. At present, aramid is mainly divided into meta-aramid (also known as aramid 1313, PMIA for short) and para-aramid (also known as aramid 1414, PPTA for short) according to its structure. [0003] Meta-aramid, whose chemical ...
