Problems solved by technology

However, the polyester hydrophilic finishing technology has a long and complicated process; in addition, the hydrophilicity of the finishing agent is completely provided by the amino and carboxyl groups in wool keratin, and the hydrophilicity is limited. Poor water resistance; in addition, the source of wool fiber is limited and the price is high, so it is difficult to apply on a large scale

Abstract

The invention relates to a preparation method of a polyester hydrophilic antistatic finishing agent emulsion and a product thereof. The preparation method comprises the following steps that raw material preparation is performed, wherein raw materials comprise polymerized monomers, an end-capping agent, an auxiliary agent and water; dehydration pretreatment of the polymerized monomers is performed;prepolymerization is performed; chain extension is performed; end capping is performed; and emulsification is performed to obtain a polyester hydrophilic antistatic finishing agent emulsion product.The preparation method has high controllability and a smooth process. A polyester hydrophilic antistatic finishing agent prepared by the preparation method introduces a side long chain polyether in amain chain, a polyhydric alcohol is adopted at the tail end and active end capping is performed, the emulsion product can be widely used for hydrophilic antistatic finishing of polyester fabrics of various types of structures, better decontamination performance can be given to the polyester fabrics, and good market prospects are achieved; and the product is safe and environmentally-friendly, and is convenient to use.

Description

technical field [0001] The invention relates to a polyester fabric hydrophilic antistatic finishing agent emulsion used for various types of tissue structures, in particular to a preparation method of a polyester hydrophilic antistatic finishing agent emulsion and a product thereof. Background technique [0002] In the field of hydrophilic antistatic finishing of polyester textiles, there is no relevant report on the preparation method of water-based polyurethane type hydrophilic antistatic finishing agent emulsion. The polyester hydrophilic finishing agent products based on the prior art are usually polyester polyether blocks or natural polyamino polymer polyester hydrophilic finishing agents. The process is complex and the environmental protection is poor. In order to solve the many inconveniences of traditional polyester fabric hydrophilic finishing agents, the polyester hydrophilic finishing agent emulsion product involved in the present invention does not need to pretr...
