Vinylon pure-spinning fibre oil solution and preparing method thereof

Abstract

The present invention provides a vinylon pure fiber oil solution and its preparation method, it consists of non-polar smoothing agent, surfactant, additives and water and the content of each component as follows: non-polar smoothing agent : 8 - 25%; surfactant: sulfate 5 - 28%, phosphate 5 - 28%, polyols fatty acid ester 5 - 20%, aliphatic alcohol ether 10-30%; auxiliaries: neutralizer 2-11%, macromolecular organosilicon polymer 0. 5-5. 0%, preservatives 0. 1%; cushion for water; both according to the percentage of weight. Because the oil solution in the invention does not contain alkylphenol category surfactants, so it reduces environmental pollution. The fiber treated by the oil solution in the invention has good smooth, wolliness, suitable graded property, antistatic property and so on, so the fiber can pass the subsequent processes smoothly and the spinnability is good; it also can adapt the craft condition of fiber production widely, such as heat-resistant, oxidation resistance, corrosion resistance and it can prevent oil solution degeneration and bad odor caused bacteria multiplying. The preparation method of the present invention is simple and need not heating in 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...

AI Technical Summary

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.
