Embodiment

[0026] 1. According to the above formula, 600 grams of 20% polyvinyl alcohol aqueous solution, 400 grams of 20% leather protein aqueous solution and 5 grams of formaldehyde are blended, filtered and defoamed into a spinning stock solution, and the wet spinneret is used at 400 grams per liter. (NH 4 ) 2 SO 4 Solidification in aqueous solution, 200 g / L (NH 4 ) 2 SO 4 Stretch 4 times in the plasticizing bath of aqueous solution, then heat treatment at 200 ℃ and carry out chemical crosslinking with formaldehyde crosslinking agent for 10 minutes, the strength of the obtained blended fiber is 2.5CN / dtex, and the moisture absorption rate is 9% , its appearance and feel are similar to silk, and can be dyed with acid dyes, and its light resistance, light resistance and corrosion resistance are better than silk.

[0027] 2. Blend 600 grams of 18% polyvinyl alcohol aqueous solution, 400 grams of 20% leather protein aqueous solution, 10 grams of non-ionic surfactant and formaldehyde,...

Abstract

The present invention features that the water solution of water soluble polymer PVA, viscose and carboxymethyl cellulose in 10-35 % concentration and water solution of leather protein in 10-30 % concentration are mixed into spinning solution; and the spinning solution is span with wet process spinning jet into blended fiber with leather core. The blended fiber has protein content greater than 25 %, hydroscopicity of 8-10 %, strength greater than 1.3-2.5 CN / dtex, prolongation of 20 %, and 3 % fixed elongation elastic resilience over 85 % as well as comprehensive performance superior to silk.

Description

1. Technical field [0001] The invention relates to a kind of skin protein / water-soluble macromolecule blended to prepare spinning stock solution, which is shaped by wet spinning. 2. Background technology [0002] At the end of the 20th century, people have higher and higher requirements for clothing, from simply pursuing durability and solving the problem of warmth to requiring beautiful clothing. Nowadays, people not only require the appearance of clothing to be beautiful, but also put forward higher requirements for the comfort, hygiene and physiology of clothing. Protein fiber and its blended fiber of protein and other high polymers are exactly what people wear. The ideal clothing material to pursue. The author has obtained the Chinese patent patent ZL90106200.6, titled "Silk Protein and Polyvinyl Alcohol Blend Fiber", the fiber protein content is >25%, and the dyeing property with acid dyes is close to that of silk, and its comprehensive performance It is superior t...
