Problems solved by technology

However, it is limited by its poor hydrophilicity, easy static electricity, poor hand feeling, and easy staining. Therefore, various finishing agents have been invented to improve the performance of polyester fiber fabrics.
The existing silicone oil smooth finishing agent grafts silicone monomers at the ends of polyester fibers, which improves the hydrophobic structure of the ends of polyester fibers and endows the fabric with smooth characteristics, but the hydrophilicity of the fabric has not been greatly improved. , and the washing resistance is not good
The polyester finishing agent can eutectic with the chain segment of the polyester fiber to form a stable structure when it is set at high temperature, thus giving the fabric a fluffy and soft feel, but the smoothness is very low

Abstract

The invention relates to application of a super-smooth multifunctional arrangement agent in a polyester fiber material. The multifunctional arrangement agent is prepared from the following raw materials according to a formula: ethylene oxide and epoxy butane block polymer, terephthalic acid, diethylene glycol and a catalyst, wherein the mass ratio of the ethylene oxide and epoxy butane block polymer to the terephthalic acid to the diethylene glycol is 1:(0.5 to 2):(0.1 to 2); the usage amount of the catalyst accounts for 0.05 to 0.5% of the total mass of the ethylene oxide and epoxy butane block polymer, terephthalic acid and diethylene glycol. The multifunctional arrangement agent has the advantages that by adopting a hydrophilic segment, when the arrangement agent is used for the polyester fiber material, the copolymeric hydrophilic segment can be grafted on molecular chains of the polyester fiber, so that the fluffy, flexible, smooth and anti-static properties are simultaneously realized; the defect of poor hydrophilicity of the smooth silicone oil arrangement agent is overcome, the defect of the smoothness of the polyester arrangement agent is overcome, the multiple functions of water washing resistance, fluffy and flexible property and the like are realized, and the blank in the multifunctional arrangement agent on market is filled.

Description

technical field [0001] The invention belongs to the technical field of chemical industry and relates to the application of an ultra-smooth multifunctional finishing agent in polyester fiber materials. The polyester fiber treated with the multifunctional finishing agent has improved water absorption and has the effect of being fluffy and soft . Background technique [0002] At present, polyester fiber is widely used because of its high mechanical strength and easy dyeing. However, it is limited by its poor hydrophilicity, easy static electricity, poor hand feeling, and easy staining. Therefore, various finishing agents have been invented to improve the performance of polyester fiber fabrics. The existing silicone oil smooth finishing agent grafts silicone monomers at the ends of polyester fibers, which improves the hydrophobic structure of the ends of polyester fibers and endows the fabric with smooth characteristics, but the hydrophilicity of the fabric has not been greatly...
