Treatment agent with excellentelasticity recovery and the the knitting textile treated therewith

摘要

The present invention relates to a fiber finishing agent having an improved elastic recovery rate and a fiber fabric knit treated with the finishing agent, wherein the fiber finishing agent having an improved elastic recovery rate comprises polytetramethylene ether glycols (PTMG) 3 to 4 and nitrosodiethanol Amine (NDEA, N-nitrosodiethanolamine) of 3.5 to 4, the internal temperature was increased to 70 to 80 ° C, and the mixture was allowed to react at a stirrer speed of 200 rpm for 30 minutes. Then, the reaction product of polytetramethylene glycol and nitrosodiethanolamine (IPDI, isophorone diisocyanate) was added at a molar ratio of 1: 0.9 to 1, dibutyl tin dilaurate (DBTDL) was added thereto, the temperature was lowered to 40 ° C, acetone was introduced, And the reaction was carried out for 3 hours while maintaining the temperature of the reaction system at 50 DEG C, and 35 to 40 mol% of hydrochloric acid (HCl) was added to 100 mol% After neutralization reaction for 3 hours, 18 to 25 mol% of ethylenediamine (EDA, Ethylen diamine) was added and chain extension reaction was carried out. When viscosity increased, acetone was added and stirred. When the neutralization reaction was completed, distilled water was slowly added for 3 hours, In water.
