Washable terylene hydrophilic finishing agent and preparation method thereof

Abstract

The invention belongs to the field of hydrophilic finishing agents, and particularly relates to a washable terylene hydrophilic finishing agent and a preparation method thereof. The invention provides a washable terylene hydrophilic finishing agent. The chemical structural formula of the washable terylene hydrophilic finishing agent is as shown in a formula I. The washable terylene hydrophilic finishing agent comprises x units, y units and z units which are sequentially and repeatedly connected, wherein the number of the x units is a positive integer from 14 to 1000; the number of the y units is a positive integer from 1 to 75; the number of the z units is a positive integer from 1 to 30; R1 is -CH3; R2 is -H, -CH2CH2OH, benzyl or -(CH2)nCH3, wherein n is a natural number from 0 to 18. According to the washable terylene hydrophilic finishing agent and the preparation method thereof provided by the invention, the technical defect that the hydrophilicity and washability of fabric cannot be simultaneously improved after a traditional hydrophilic finishing agent acts on the fabric can be effectively overcome. 本申请属于亲水整理剂领域，尤其涉及一种耐洗性涤纶亲水整理剂及其制备方法。本申请提供了一种耐洗性涤纶亲水整理剂，其化学结构式如式Ⅰ所示；所述耐洗性涤纶亲水整理剂包括依次重复连接的x单元、y单元和z单元；所述x单元的数量为14～1000的正整数；所述y单元的数量为1～75的正整数；所述z单元的数量为1～30的正整数；所述R1为‑CH3；所述R2为‑H、‑CH2CH2OH、苄基或‑(CH2)nCH3，其中，所述n为0～18的自然数。本申请提供的一种耐洗性涤纶亲水整理剂及其制备方法，能有效解决传统的亲水整理剂与织物作用后无法同时改善织物的亲水性和耐洗性的技术缺陷。
