Problems solved by technology

[0003] Existing oil composition mainly contains two types, one is ester type, most of which are based on natural esters, such as US4293460, which mainly consists of natural oils, polyoxyethylene alkylphenols, phosphates, etc., and its characteristics It has strong adhesion with rubber, low strength loss after twisting and weaving of raw silk, but poor spinnability and high degree of tarring; the other is polyether type oil composition, such as CN1242451A, from 60 to 90% of ethylene oxide and propylene oxide copolyether, the rest of antistatic agent and defoamer, etc., among which polyether is unmodified ordinary polyether, which is characterized by good spinnability and smoke Less, low degree of tarring, the disadvantage is that the strength loss after twisting of the raw yarn is high, and the compatibility between the oil agent and the latex is poor, resulting in poor adhesion between the cord fabric and the tire
"Synthetic Fiber Industry", 1995, 18 (6), "development of nylon high-speed spinning cord oil agent" published on P8~13, discloses a kind of oil agent, the composition of this oil agent is based on polyether, and the advantage is Excellent emulsifying performance and good heat resistance, but the disadvantage is that the strength of the raw silk will drop a lot after being placed

Abstract

A composite oil for spinning cord yarn contains synthetic ester, polyether A, polyether B, antistatic agent, physical propoerties regulator and viscosity improver. Its advantages are high stability, high temp resistance and smoothness, and high spinnability and less strength loss of raw fibres.

Description

field of invention [0001] The invention relates to a synthetic fiber spinning oil composition, in particular to a high-speed spinning cord oil composition. Background of the invention [0002] Vehicle tire cord is the reinforcing material of tires, and most of them used viscose fiber as raw material in the past. With the development of synthetic fibers, nylon, polyester, aramid, etc. are all used, and nylon is widely used because of its excellent heat resistance, impact resistance and fatigue resistance. In the spinning and drawing process of the cord, the undrawn yarn needs to be treated with an oil composition, drawn at high speed and high temperature at a high rate, wound, and then false twisted, weaved and dipped. Therefore, the quality of the oil agent directly affects the spinnability of the cord, including the amount of smoke, carbon deposition performance, and waste silk rate. At the same time, the quality of the oil agent also affects the physical properties of the...
