Problems solved by technology

[0002] Vinylon has good properties, but the yarn strength of vinylon textiles is low, and problems such as poor evenness and many neps hinder the application of vinylon products in many fields
Although vinylon has good chemical stability, sunlight resistance and weather resistance, it is insoluble in general organic acids, alcohols, esters and other solvents, it is not easy to be moldy, and its strength loss is not large when exposed to sunlight, and vinylon is warm. It is also very good in air permeability, air permeability and wear resistance, so it is suitable for making products such as ropes, tapes, canvas, fishing nets, wall coverings, tents and tire meridians, but it requires extremely high strength to make the above items, so it is necessary to use vinylon. Good properties and high strength of vinylon, good evenness and less neps are a difficult problem before us. However, the vinylon staple fibers we usually use are 1.5D*38mm, 1.5D*38mm, The strength of 2.5D*51mm, 4D*64mm and vinylon yarn spun from high-strength and high-modulus staple fibers is far from meeting the requirements

Abstract

The invention relates to a spinning method for vinylon filament cut bodies. The method comprises raw material selection, ab oily liquid adding process, a mixing process, a carding process, a drawing process, a roving process, and a spun yarn process. The spinning method can greatly improve strength of vinylon yarns, so strength, abrasive resistance, tear resistance, and other properties of a vinylon product are greatly improved. By using a method of cutting vinylon filaments to obtain high-strength vinylon raw material, a problem that vinylon yarns are not high in strength is solved. Through optimized proportion of oily liquid added in short fibers cut by the vinylon filaments, and by using different carding methods and different drafting forms in the roving process, problems of few neps and good uniformity of evenness in the vinylon yarns are solved.
