Abstract

The invention discloses the formula, the production process and the application of moisture absorbent and sweat conductive comfortable finishing agent which is used for modifying the polyester fiber to enable the polyester fiber to have moisture absorbent and sweat conductive capabilities. The formula of the moisture absorbent and sweat conductive comfortable finishing agent contains: polyethylene glycol, ethylene glycol, polyether and dimethyl terephthalate. The two-step continuous production process is adopted: in the first step of esterifying, polyethylene glycol, ethylene glycol, polyether and dimethyl terephthalate are put into a reaction vessel for esterification under the action of catalysts; and in the second step that the material produced after the esterification is transported to a polymerization kettle for polymerization under the actions of high temperature, vacuum, and catalysts, in order to generate polyester-polyether copolymer with high molecular weight to be 30000-50000, namely, the moisture absorbent and sweat conductive comfortable finishing agent. The moisture absorbent and sweat conductive comfortable finishing agent can be directly used or be used after being mixed with substances such as amino silicone oil and so on, and carry out chemical modification on the polyester fiber.

Description

technical field [0001] The invention relates to a moisture-absorbing and sweat-wicking comfortable finishing agent and its production process and application. Background technique [0002] As we all know, polyester fiber has poor moisture absorption and perspiration, antistatic performance, easy decontamination performance, and fluffy softness. Therefore, the textiles processed with polyester fibers are less wearable. Contents of the invention [0003] The first technical problem to be solved by the present invention is to provide a moisture-absorbing and sweat-wicking comfortable finishing agent for modifying polyester fiber to make it have good moisture-absorbing and sweat-wicking properties. [0004] In order to solve the above-mentioned technical problems, the first technical problem to be solved by the present invention is: moisture-wicking and comfortable finishing agent, comprising the following components in parts by weight: 80-100 parts of polyethylene glycol, 10...
