A kind of oil agent for fluorine-containing polyester FDY fiber and preparation method thereof

Abstract

The invention relates to an oiling agent for fluorine-containing polyester FDY fiber and a preparation method of the oiling agent. The oiling agent for the fluorine-containing polyester FDY fiber comprises active components in parts by weight: 40-60 parts of mineral oil, 20-35 parts of polyoxyethylene, 5-10 parts of a phosphate ester potassium salt, 8-16 parts of polyethylene glycol fatty acid ester, 1-5 parts of sodium alkyl sulfonate and 1-5 parts of a perfluoroalkyl acrylate. The preparation method comprises: mixing the component and stirring, controlling the temperature at 40-55 DEG C to obtain the FDY oiling agent with good performances. The FDY oiling agent has good comprehensive performance, good compatibility, heat resistance and sizing performance. Due to introduction of the fluorine element, the oiling agent is substantially improved in wettability and permeability, and helps to effectively solve the problemthat conventional oiling agents for fluorine-containing polyester FDY fiber is bad in wettability.

Description

technical field [0001] The invention relates to an oil agent for fluorine-containing polyester FDY fiber and a preparation method thereof, in particular to an oil agent for fluorine-containing polyester FDY fiber introduced with fluorine element and a preparation method thereof. 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] FDY oil agent for polyester fiber is a kind of oil agent used in the production process of polyester FDY ...

AI Technical Summary

Problems solved by technology

[0005] The problem to be solved by the present invention is to provide an oil agent suitable for use in the spinning process of fluorine-containing polyester FDY fibers, so as to make up for the fact that the existing FDY oil agents cannot well wet the fluorine-containing polyester fibers

Solve the problem of unsatisfactory adhesion and wettability between traditional FDY oil agent and fluorine-containing polyester fiber, which is beneficial to the production and processing of fluorine-containing polyester FDY fiber
