Problems solved by technology

Among them, the performance of textiles directly affects people's quality of life. Textiles will be exposed to various chemicals during the production and processing process, especially after finishing processing will use a wide variety of finishing agents. Finishing is to improve product grade and added value. However, some of the finishing agents currently on the market only have a single performance and cannot meet other functions; although some have good finishing effects, they may contain chemical components that are toxic and endanger human health; some Pollutants are produced during the preparation process, polluting the air environment

Abstract

The invention provides a multifunctional SSF / B type polyester finishing agent and a preparation method thereof. The finishing agent is prepared from, by weight, 30-65 parts of polyethylene glycol, 5-15 parts of triethylene glycol, 13-35 parts of methyl phthalate, 3-10 parts of methylbenzene and 0.1-1 part of a calcium salt catalyst. The preparation method includes steps of material preparation, dewatering, pre-polymerization reaction, negative-pressure dealcoholization, polymerization reaction, flaking and packaging. The finishing agent has a modification effect on polyester fiber materials, and the modified polyester fiber materials have great moisture absorption and sweat release performances and have advantages of high fluffiness, coziness, softness, antistatic performance, smoothness, hydrophilcity, easiness in decontamination and the like. In addition, the finishing agent is also applicable to functional finishing of chemical fiber yarns and fabrics of polyamide fibers and the like.

Description

technical field [0001] The invention relates to the technical field of post-processing of textiles, in particular to an SSF / B type polyester multifunctional finishing agent and a preparation method thereof. Background technique [0002] Finishing agent is to endow textiles with excellent use, safety, appearance and other properties in order to meet some special requirements of textiles. Since the functional finishing of textiles is aimed at certain specific properties of textiles, it has strong purpose and good effect. The value is also high. After the textiles are functionally finished, their purpose and scope of use are clear, and they are very popular among consumers. [0003] With the development of social economy and the improvement of people's living standards, people pay more attention to the most basic elements of life, such as clothing, food, housing and transportation. Among them, the performance of textiles directly affects people's quality of life. Textiles will...
