Production process of wool protein compound viscose fiber

Abstract

The invention provides a production process of wool protein compound viscose fiber, which belongs to the technical field of viscose fiber. The process comprises the steps of preparing a wool protein spinning solution, blending the wool protein spinning solution with a viscose spinning solution, spinning, solidifying and curing and performing aftertreatment to obtain the wool protein compound viscose fiber. In the invention, the addition of toxic substances is avoided, the obtained finished product is more suitable for manufacturing the textile products with high safety, such as intimate apparels and the like, and shows the advantages in environmental friendliness.

Description

technical field [0001] The invention relates to a production process of viscose fiber, in particular to a production process of wool protein composite viscose fiber, which belongs to the field of viscose fiber. Background technique [0002] Wool is a natural protein fiber resource that has been used by humans for a long time. According to the latest statistics released by the International Wool Textile Organization, in the past 8 years, the world's total wool production has dropped by 160 million kg net wool, while the production of wool for clothing has dropped by 18%. In 2009-2010, wool production declined again, which shows that wool resources are facing a shortage. Wool is one of the largest imports of animal products in my country. At present, the import volume has accounted for 2 / 3 of the domestic wool production, and has become one of the largest wool importing countries in the world. However, domestic wool is at a disadvantage compared with imported wool in terms of...

AI Technical Summary

Problems solved by technology

This substance will still remain on the fiber after subsequent washing, which is impossible under the current environmental protection pressure of actual production, and the heavy metals and toxic substances in the finished product exceed the standard

[0005] In addition, due to the use of a variety of animal proteins, the source is relatively complicated, and the properties (protein content, solution viscosity, etc.) and stability of the protein solution are very low

[0006] Since the above-mentioned patent adopts discontinuous production, there will often be a certain stock of protein liquid, and the existence of tyrosine crystal substances in the protein liquid will lead to protein sedimentation and flocculation, making the spinnability of subsequent fibers extremely poor, and easy to block and spray Filament head and filter element, produce a large number of coarse fibers and doubling
