Cord thread spinning oil

Abstract

The invention discloses cord thread spinning oil. The cord thread spinning oil comprises, by mass, 40-60% of plant oil, 30-50% of compound fatty acid ester, 1-10% of non-ion surfactant, and the balance antioxidant. The plant oil is selected from at least one of peanut oil, soya-bean oil, linseed oil, castor oil, health oil, and rapeseed oil, refined processing is carried out on the plant oil, iodine value is higher than 70, the compound fatty acid ester is pentaerythritol ester or trimethylolpropane ester, and the non-ion surfactant is fatty alcohol-polyoxyethylene ether, fatty alcohol polyurethane propylene ether or fatty alcohol polyoxyethylene polyoxypropylene.

Description

technical field [0001] The invention relates to a chemical fiber auxiliary agent, in particular to a cord spinning oil agent. The oil is high temperature resistant and environmentally friendly. Background technique [0002] Cord is a kind of polymer material formed by melt-spinning fibers of polyamide resin or polyester resin, and then multi-bundle plying, drawing and twisting. Cord has high tensile strength and low bending strength in the axial direction, and is the main material in the manufacture of car and light truck tire frames. As the skeleton material in the tire, the cord is the main body that bears and transmits stress. The strength, elongation and dimensional stability of the cord are the key to improving tire performance and product quality. [0003] Cord spinning oil is a fine chemical mainly used in the spinning production and post-processing of polyamide, polyester cord fibers and industrial yarns. In the production process of cord fiber drafting, winding, ...

AI Technical Summary

Problems solved by technology

[0004] Most of the cord spinning oils in the prior art use mineral oil and animal fats as lubricants, and a large proportion of solvent oil, water, alcohol, volatile solvents and other substances are added to reduce the viscosity of the oil system. During use, the oil agent has poor permeability, slow spreading speed on the fiber surface, insufficient smoothness, insufficient draft uniformity of cord fibers, low breaking strength of finished fibers, which cannot meet the requirements of subsequent high-end tire manufacturing, and poor high temperature resistance. The oil agent is easy to coke and has a large amount of smoke, which has a great impact on the production environment

[0005] Within the scope of the applicant's literature search, there is no report on the environmentally friendly high-temperature-resistant spinning oil suitable for the spinning of cords and the subsequent drafting, twisting, weaving, and dipping processes.
