Non-emulsion type pure oiling agent for high speed spinning of polyamide-6 filaments

Abstract

The invention discloses a non-emulsion type pure oiling agent for the high speed spinning of polyamide-6 filaments, wherein a smoothing agent consists of three polyether type non-ionic surfactants, i.e. fatty alcohol-ethylene oxide-propylene oxide copolyether, fatty alcohol-polyoxyethylene ether and polyxyethylated alkylphenol; a collecting agent is the non-ionic surfactant, i.e. fatty acid polyoxyethylene ether ester; an antistatic agent is fatty alcohol-polyoxyethylene ether phosphate and amine (kali) salt of alkyl phosphate; a binding additive is Ac; and a regulating agent is water. The pure oiling agent for the high speed spinning of the polyamide-6 filaments generates little smoke, does not gel, gather or deposit, and is of good heat stability and chemical properties; and in addition, after a spray nozzle is applied with oil, the process requirements on air bath at the high temperature of 230 DEG C, high speed spinning (3000m / min) and strong drafting can be met. The requirements on the properties of precursors, thrown silk, dipping glue and tyre cords are met, so that the property of a polyamide-6 tyre fabric reaches the high level of national standards.

Description

technical field [0001] The invention belongs to the chemical fiber oil agent in the production and processing of chemical fiber, especially the pure oil agent produced by nylon 6 one-step high-speed spinning filament process cord, which is specially used in the production and processing of nylon 6 filament high-speed spinning cord fabric. It is used to adjust the friction characteristics between the fiber and its contact objects during the spinning process of one-step high-speed filament equipment. Background technique [0002] Nylon-6 oil agent is an important category of chemical fiber oil agents. High-speed spinning oil agent is an important direction for the development of spinning oil agents in recent years. With the development of chemical fiber spinning technology to high speed, the chemical fiber The performance requirements of the oil agent are even higher. Over the years, my country's high-speed spinning nylon 6 oil agent has basically occupied my country's spinni...

AI Technical Summary

Problems solved by technology

High molecular weight, good heat resistance, non-volatile, high oil film strength, good clustering, but more spinning smoke, easy to coke, uneven oiling, poor diffusivity

Low molecular weight, no smoke, no condensation, but poor heat resistance

[0006] At present, most of the oils for high-speed spinning of nylon 6 in China are emulsions, which can replace Syntex371L high-speed spinning of nylon 6 cord fabrics in West Germany. The actual formula and specific components have not been publicly reported.
