Abstract

The invention discloses a short-fiber oil agent for aromatic polyamide fiber, which is prepared from 3 to 40 weight percent of polyol fatty acid ester, 5 to 70 weight percent of polyoxyethylene polyol fatty acid ester, 5 to 40 weight percent of fatty alcohol ethylene oxide-propylene oxide random copolyether or polyether ester, 1 to 40 weight percent of fatty alcohol polyethenoxy ether organic phosphate salt, 1 to 30 weight percent of fatty alcohol polyethenoxy ether sulfuric acid ester salt and 0.1 to 10 weight percent of polyether modified silicon oil. The oil agent can solve the defects of the poor main performance, i.e. poor electrostatic resistance, poor heat resistance, poor saturation, and the like of the prior oil agent, aims to provide an aramid short-fiber oil agent which has excellent electrostatic resistance, smoothness, softness and dyeing uniformity, enables the aramid short fiber to have excellent post processing performance, and the like.

Description

technical field [0001] The invention relates to a lubricating oil composition characterized by an oxygen-containing polymer mixture as an additive, in particular to an oil agent for aromatic polyamide fiber short fibers. Background technique [0002] Aromatic polyamide fibers (Aromatic polyamide fibers) are aramid fibers, and their molecules are linear polymers formed by directly connecting two aromatic rings with amide bonds. There are two main types, one is aramid fiber 1313 (product of DuPont Company The name is Nomex), the chemical name is poly-m-phenylene isophthalamide (Poly-m-phenylene isophthalamide, PMIA) fiber, and the molecular formula is: [0003] [0004] It has good heat resistance and flame resistance. It can be used for more than ten years at 220 ° C. The fabric does not deform at 260 ° C. It will gradually carbonize and not melt when it is above 370 ° C. It can be used to make space suits, racing suits, fire suits, heat-resistant Anti-corrosion filter cl...
