Abstract

The invention discloses a chinlon hydrophilic softening finishing agent. The chinlon hydrophilic softening finishing agent is prepared from polyethylene glycol, glyceryl stearate citrate, adipic acid,ethylene glycol monostearate and caprolactam at a weight ratio of 1:2.5-3:2.5-3:0.5-1:0.1-0.5; the dosage of catalysts is 0.2-0.6% of the total weight of polyethylene glycol, glyceryl stearate citrate, adipic acid, ethylene glycol monostearate and caprolactam. When applied to processing chinlon fiber or chinlon fiber fabrics, the chinlon hydrophilic softening finishing agent can endow the chinlonfiber or chinlon fiber fabrics with fluffy, soft and smooth effects and hydrophilic, antistatic, washable and highly fast properties and overcome the original shortcomings of poor water absorbency, heavy static electricity and poor soft performance of chinlon fiber materials, and meanwhile, is simple in raw material acquisition and preparation and completely superior to general commercial chinlonfinishing agent and silicon oil smoothening finishing agent, thereby having a good prospect.

Description

technical field [0001] The invention relates to the field of textile dyeing and finishing, in particular to a nylon hydrophilic softening finishing agent and a preparation method thereof. Background technique [0002] As one of the main fibers of textile fabrics, nylon fiber material is widely used in daily life due to its excellent wear resistance and elasticity, such as stockings, underwear fabrics, mountaineering suits, etc. [0003] However, nylon fiber material also has the following disadvantages: 1. There are few hydrophilic groups in the molecular chain of nylon fiber, and the water absorption of the fiber material is poor; 2. The electrostatic phenomenon of nylon fiber material is serious; 3. Most of the nylon fiber is a polyamide structure , soft performance is worse than natural fibers. Therefore, it is very necessary to study the hydrophilic soft finishing of nylon fiber. Contents of the invention [0004] In order to overcome the deficiencies of the above-me...
