A kind of oil agent for fluorine-containing polyester poy fiber

Abstract

The present invention relates to an oil agent for fluorine-containing polyester POY fiber and a preparation method thereof. The effective components of the oil agent for fluorine-containing polyester POY fiber are, in parts by weight, random polyether, 50-60 parts; Polyethylene glycol fatty acid ester, 20-32 parts; phosphate potassium salt, 10-15 parts; perfluoroalkyl acrylate, 2-5 parts. The method: take random polyether, heat it to 40-60°C, stir and mix polyethylene glycol fatty acid ester, phosphate potassium salt and fluorine-containing acrylate evenly, then add it to random polyether, stir The oil agent for fluorine-containing polyester POY fiber with excellent performance is obtained. The oil agent for fluorine-containing polyester POY fiber in the present invention has excellent comprehensive performance, low surface tension of the oil agent, increased wetting performance and permeability of the oil agent, and can better form a uniform oil film on the surface of the fluorine-containing polyester fiber . The oil agent effectively solves the problem of unsatisfactory adhesion and wettability between traditional oil agents and fluorine-containing polyester fibers.

Description

technical field [0001] The invention relates to an oil agent for fluorine-containing polyester POY fibers, in particular to an oil agent for fluorine-containing polyester POY fibers introduced with fluorine element. Background technique [0002] Polyester fibers, especially polyester, have many excellent textile properties and wearing properties, and are widely used by people. In the production process of polyester fiber, for different types of fibers, different types of oil agents are required to protect the fibers to a certain extent, so that unnecessary performance damage occurs during the production process. For example, the production of POY yarn requires When it comes to POY oil, FDY oil is needed for the production of FDY yarn, and short fiber oil is needed for the production of short fiber. [0003] POY oil agent for polyester fiber is a kind of oil agent used in the production process of polyester POY yarn. Fiber treatment agent for smoother processing. The selec...

Problems solved by technology

The surface energy of fluorine-containing polyester fiber is small, and the oil resistance is strong, and it is difficult for the usual POY spinning oil to wet and penetrate quickly; the POY oil of the present invention reduces the surface tension of the oil itself due to the introduction of fluorine. The wettability and penetration of the oil are greatly increased, which makes it easy to wet and spread on the surface of the fluorine-containing polyester fiber, forming a uniform oil film with moderate strength, which effectively solves the problem of traditional oils and oil-containing oils. The problem of unsatisfactory adhesion and wettability between fluoropolyester fibers, and it can also maintain the good mechanical properties of polyester fibers themselves, which is beneficial to the bundling and processing of fibers
