Problems solved by technology

[0004] Aramid fiber has a straight molecular chain and high crystallinity, no active groups on the surface, and a glass transition temperature above 275°C. Therefore, high temperature and high pressure methods or high temperature carrier methods are generally used for dyeing and finishing. These two methods are also difficult to obtain good results; in addition, the molecules of the moisture-wicking and sweat-wicking finishing agent have a certain degree of polymerization, which is more difficult to adsorb and fix on the smooth surface of the fiber than the dye molecules

Abstract

The invention discloses a method for modification, moisture transfer, perspiration and finishing of aromatic polyamide fabric, and belongs to the technical field of textile chemical industry. Through physical and chemical modification on the aromatic polyamide fabric, the method improves the physical and the chemical states on the surface of fiber, and facilitates the moisture transfer, the perspiration and the finishing of the aromatic polyamide fabric. The process flow comprises the steps as follows: a, washing and oil removing of the aromatic polyamide fabric; b, pretreatment of the aromatic polyamide fabric; and c, moisture transfer, perspiration and finishing of the aromatic polyamide fabric. The aromatic polyamide fabric treated by the method has good moisture transfer, perspiration, humidity and heat cosiness, and simultaneously has the properties of heat resistance, flame retardancy, lightness and high strength. The method has the advantages that the process is simple, the cost is low, the aromatic polyamide fabric with moisture transfer and perspiration properties can be widely applied to special departments of aviation, space flight, war industry, communications and the like, and can also meet the demands of costume outfit of personnel engaged in fire control, life saving and the like.

Description

technical field [0001] The invention relates to a method for modifying and finishing aromatic polyamide fabrics, in particular to a method for moisture-wicking and sweat-wicking finishing of aromatic polyamide fabrics, and belongs to the technical field of textile chemicals. Background technique [0002] Aramid fiber (referred to as aramid fiber) is a high-performance organic fiber, mainly a linear polymer composed of amide bonds (-CO-NH-) and aromatic rings, with high strength and high modulus , low density, flame retardant, non-melting in case of open flame and good chemical stability and other excellent properties, it is widely used in personal protection and special industrial fields, especially in aerospace and military fields. [0003] However, the hydrophobic surface of this type of fiber leads to extremely poor moisture-wicking and sweat-wicking properties of the fabric, which greatly affects the comfort of related clothing. At present, the research on moisture-wick...
