Pearl composite fibre and its production method

Abstract

This invention discloses a pearl compound fiber and its making method, the pearl compound fiber is produced by the mixture and co-gather of the hydrolysis pearl and polyvinylalcohols, the method as follows: first dissolving the material, filtering, and sending them into the action kettle by a certain proportion, then stirring, mixing up, and heating the spinning original liquid, then filtering and sending it into the deaeration barrel, warming the deaeration barrel, and then spinning, drawing, drying and shaping, cutting off, curling, acetaling and tying, finally obtaining the product. The effect is that the product's bleaching and dying capability, its white and bright are all improved greatly.

Description

Technical field [0001] The invention relates to a pearl composite fiber used in the textile industry made from hydrolyzed pearls and polyvinyl alcohol, and also relates to a manufacturing method of the composite fiber. Background technique [0002] Because vinylon produced from polyvinyl alcohol has some shortcomings in dyeability, wearability, and shape retention, many improvement methods have been adopted in China in recent years, the most important of which is the use of soybeans, milk or other animals. A variety of new composite fibers made by blending and copolymerizing vegetable protein and polyvinyl alcohol, such as "Soymilk Composite Fiber and Its Manufacturing Method" developed by the applicant and others in cooperation with others, is one of them. These technical schemes have solved the above-mentioned deficiencies in the vinylon that is made of polyvinyl alcohol as raw material well indeed, have obtained obvious economical and technical effect, but because the com...

Problems solved by technology

These technical schemes have solved the above-mentioned deficiencies in the vinylon that is made of polyvinyl alcohol as raw material well indeed, have obtained obvious economical and technical effect, but because the composite fibers in these technical schemes are all based on protein As the main component, these proteins will be denatured and yellowed to a certain extent during the heat setting process in the fiber production process, which will cause some difficulties in the bleaching and dyeing process of its textile products, and the whiteness and brightness that the product can achieve Neither is ideal

In addition, due to the limitation of process conditions, the protein spinning stock solution has a strong alkalinity, with a pH value of 10-13, which is not only corrosive to the manufacturing equipment, but also has a certain impact on the quality control of the product. difficulty

In addition, the existing soybean and milk composite fiber also lack some health care functions and cannot meet some special needs of people.
