Abstract

The invention discloses a method for modification, dyeing and multifunctional composite finishing of aramid fiber, and belongs to the technical field of textile chemical industry. Through surface physical and chemical modification for the aramid fiber, the method improves the physical and chemical states of the aramid fiber surface and is favorable for the dyeing and after finishing of the aramid fiber. The specific process flow comprises the following steps of cleaning before the dyeing of the aramid fiber, pretreatment of the aramid fiber, dyeing of the aramid fiber, and multifunctional composite finishing of the aramid fiber. Not only the dyeing property of the aramid fiber treated by the method is remarkably improved, but also the dyeing fastness is good, the aramid fiber has good moisture permeability particularly, and simultaneously the aramid fiber is endued with good anti-ultraviolet ageing function. Moreover, the aramid fiber is subjected to composite finishing by adopting a nano composite sol, and the method has wide applicability, simple process, relatively low treatment cost, and low requirements on the applied technology and equipment.

Description

technical field

[0001] The invention discloses a method for modifying, dyeing and multifunctional composite finishing of aramid fiber, which belongs to the technical field of textile chemical industry. Background technique

[0002] Kevlar is poly-p-phenylene terephthalamide fiber, aliased as aramid resin and aramid fiber, also known as Kevlar, which belongs to aromatic polyamide. It was first successfully developed by DuPont in the United States in the 1960s. Due to its special structure, aramid fiber has excellent high temperature resistance and flame retardancy, so it is widely used in firefighting clothing and military protective clothing, and is a strategic material. However, as clothing for special industries such as firefighting, special signs and colors are required to identify and search for emergency and chaotic scenes. However, because the rigid polymer chain of aramid fiber is highly crystalline and has no active groups on the surface, and its glass transition te...
