2, wet spinning
Utilize common wet method spinning head, spinning solution is sprayed into coagulation forming in the aqueous solution of sodium sulphate or ammonium sulfate with measuring pump, solidifying solution concentration is 200～400 grams per liters, and stretches 30～800% in the plasticizing-bath of sodium sulphate or ammonium sulfate.
3, spinning post processing
Blended fiber with after stretching carries out post processing respectively, carries out chemical crosslinking with formaldehyde, acetaldehyde, glyoxal or glutaraldehyde cross-linking agent simultaneously, and the time is 2～120 minutes.
Blended fiber hide collagen content of the present invention＞25%, with its dyeability of acid dyeing near silk, hygroscopicity 8～10%, outward appearance, feel, gloss exactly like silk, intensity＞1.3～2.5CN/dtex, extend the answer of 20%, 3% specified elongation elasticity and reach more than 85%, it is a kind of silk spinning fiber of high comprehensive performance.
The present invention has following advantage:
1, hide collagen replaces silk-fibroin or pupa albumen, has reduced cost, has simplified technological process, has shortened production line, and equipment investment is few, produces easy to controlly, and protein utilization is up to more than 90%.
2, the present invention adopts the blended fiber of general wet method spinning head spinning skin-core structure, and the blended fiber of wet production skin-core structure is become a reality, and has avoided difficulties such as technology that baroque spinning head brings and processing.
3, the blended fiber of the spun core-skin layer of wet method spinning head structure, wherein hide collagen is distributed in cortex, premium properties such as the gloss of silk, slim and graceful graceful, comfortable and easy to wear, health have been kept, polyvinyl alcohol etc. mainly are distributed in sandwich layer, skeleton as fiber, and give fiber good mechanical performance, characteristics such as sun-proof and corrosion resistant.
