Problems solved by technology

However, alkylphenols have high biological toxicity, poor biodegradability, and great pressure on environmental protection
However, oil products that do not contain alkylphenols often cannot meet the requirements of endowing fibers with good smoothness, softness, cohesion, antistatic and other properties in the process of fiber production and processing, making the fiber processing performance poor and the fibers Increased processing costs; or corrosion of equipment due to the introduction of halogen-containing cationic surfactants
In addition, in the existing oil products, the oil itself is transparent, but it is often not transparent at the same time when the emulsion is prepared, that is, the emulsion of the oil is unstable, which leads to uneven oiling of the oil during use. Therefore, it cannot meet the special needs of the above-mentioned fiber production and processing.

Abstract

The invention provides a vinylon pure spinning fiber oil and its preparation method, which is composed of non-polar smoothing agent, surfactant, auxiliary agent and water, wherein the content of each component is: non-polar smoothing agent: 8-25%; in surfactants: 5-28% sulfate esters, 5-28% phosphate esters, 5-20% polyol fatty acid esters, 10-30% fatty alcohol ethers; in additives: neutralizer 2 ~11%, high molecular silicone polymer 0.5~5.0%, preservative 0.1%; the balance is water; all are calculated by weight percentage. Since the oil agent of the invention does not contain alkylphenol surfactants, environmental pollution is reduced. The fiber product treated with the oil agent of the present invention has good smoothness, softness, suitable cohesion (or clustering property), antistatic property, etc., so that the fiber can pass through various post-processing procedures smoothly, and has good spinnability; Moreover, it can be widely adapted to the process conditions of fiber production, such as heat resistance, oxidation resistance, corrosion resistance, and prevention of oily odor and deterioration caused by bacterial reproduction. The preparation method in the present invention is simple and does not need heating during preparation.

Description

technical field [0001] The invention relates to a fine chemical product, in particular to a vinylon pure spinning fiber oil used in spinning, spinning and spinning of vinylon fibers. The invention also provides a preparation method of the oil. Background technique [0002] The polyvinyl formal fiber obtained by treating polyvinyl alcohol for fiber with aldehydes is commonly called vinylon fiber. Vinylon is a fiber with poor crimp stability and untwisting slippage among synthetic fibers. It must rely on oil agents to improve and enhance its spinning and spinning performance in the weaving process. The purpose of oiling is to coat the surface of the fiber bundle with a layer of oil film, endow the fiber bundle with basic characteristics such as smoothness, antistatic and bunching, and its main function is to improve the smoothness of the fiber and maintain the contact between fibers and fibers and between fibers and others Appropriate friction coefficient between parts; reduc...
