Problems solved by technology

In addition, in the prior art, in order to promote the strengthening of the oil film, ester groups or amino compounds that have a high affinity for polyester and lubricants are often used, and at the same time, because of their strong hydrophilicity, they increase the oil The viscosity of the agent emulsion affects the oil film strength and dispersibility

Abstract

The invention relates to an oil agent for chopped polyester fiber. The oil agent is prepared by mixing the following components in percentage by weight: 25-35% of isooctyl stearate, 5-15% of sodium diethyl ethanol sulfonate succinate, 3-5% of sorbitan oleate, 15-25% of dodecyl polyoxyethylene ether (5), 8-12% of dodecyl polyoxyethylene ether (10), 8-12% of potassium POE (polyoxyethylene) alkyl phosphate, 3-5% of softener A, 3-5% of fatty alcohol ethylene oxide and 1-8% of regulator. The oil agent provided by the invention has the advantages of excellent emulsion stability, antistatic property and smoothness as well as high oil film strength, and is suitable for production of chopped polyester fiber or chopped cotton polyester fiber which has high total tow denier number and can be spun at high speed. In addition, because the oil agent has low production cost and very large use amount, the economic benefit is obvious.

Description

technical field [0001] The invention relates to a polyester staple fiber oil agent. Background technique [0002] Chemical fibers generate static electricity due to constant friction during spinning and textile processing. Auxiliaries must be used to prevent or eliminate static electricity accumulation, and at the same time endow fibers with soft, smooth and other characteristics, so that they can pass through the subsequent process smoothly. These additives are collectively referred to as chemical fiber oils. Chemical fiber oils should have the following characteristics: smooth, antistatic, clustering or cohesion, etc.; good thermal stability, low volatility; no corrosion to metals; good washability, without affecting fiber color; odorless and non-toxic Stimulant, no delamination, no corruption and deterioration under specified storage conditions; easy to prepare and use, easy to obtain raw materials, reasonable cost, etc. [0003] Polyester staple fiber is a kind of hydr...
