Abstract

The invention discloses a forming processing oiling agent suitable for treating heterocyclic aramid precursor, and belongs to the technical field of chemical fibers. The forming processing oil agent is prepared from the following components in percentage by mass: (a) 20 to 50 percent of isooctyl stearate; (b) 15%-40% of fatty alcohol potassium phosphate; (c) 10%-30% of polyethylene glycol monooleate; and (d) 5%-15% of polyoxyethylene sorbitan monooleate. The oiling agent has the characteristics of lubricity, dispersity and volatility at the same time, is used for treating heterocyclic aramid, not only reduces the friction coefficient between fibers and a yarn guide part, but also enables monofilaments of the fibers to be uniformly dispersed and avoids monofilament adhesion, and meanwhile, solves the problem that volatile matters in the fibers are difficult to remove due to the fact that the oiling agent is attached to the surfaces of the fibers to form mucosa. The oiling agent is used for treating heterocyclic aramid fibers, so that fibers with more excellent performance can be obtained.

Description

technical field [0001] The invention relates to a manufacturing technology of heterocyclic aramid fiber, more specifically, the invention relates to a forming processing oil agent suitable for processing heterocyclic aramid fiber raw silk, which belongs to the technical field of chemical fiber. Background technique [0002] Heterocyclic aramid fiber is a ternary, quaternary or quinary copolymer fiber based on the molecular structure of domestic aramid fiber III and modified by molecular chain structure. Domestic aramid III is a heterocyclic aromatic polyamide fiber similar to Russian APMOC fiber. Aramid III polymer is formed by the copolymerization of three monomers: terephthaloyl chloride, p-phenylenediamine, and 5(6)-amino-2-(4-aminophenyl)benzimidazole. [0003] Heterocyclic aramid (including aramid III) precursors are usually prepared through spinning, coagulation, washing, oiling, drying and other processes. Due to the different molecular chain structures of fibers, t...
