Abstract
A kind of silk-fibroin and polyvinyl alcohol blending fiber are characterized in spinning solution is made in the salting liquid blend of polyvinyl alcohol water solution and silk-fibroin, utilize common wet method spinning head to spin the blended fiber with skin-core structure.The protein content of this fiber＞25%, with the dyeability of ACID DYES near silk, hygroscopicity 8-10%, outward appearance, feel and gloss exactly like silk, and intensity＞3CN/dtex extends 20%, 3% specified elongation elasticity is replied and is reached more than 85%, and it is the silk spinning fiber that a kind of combination property is better than silk.For the utilization of waste material in filature, silk spinning and the silk garment production, turn waste into wealth and opened up new way, remarkable economic efficiency and social benefit are arranged.
Description
The invention belongs to protein and polyvinyl alcohol blending is made stoste, utilize the wet spinning forming field.This fiber has the distinctive gloss of silk dyeability, absorbability, wholesomeness and silk, feel and silk
, its sun-proof, corrosion resistant and mechanical property are better than silk again.
China's silk aboundresources, with a long history, output accounts for the No. 1 in the world.Yet, in silk reeling process, account for the pin material of raw silk 76.3%, wherein part is used for silk spinning, and silk spinning produces waste material.Tailing from filature waste material, silk spinning waste material and silk garment production accounts for 1/3rd of silk total amount, also has a large amount of pupa albumen in addition, all is underutilized, and emits contaminated environment, causes public hazards.How to utilize these resources, turn waste into wealth that this is the problem extremely paid close attention to of people in recent years.Soviet Union и л л а р и о н о в а.

The solvent of silk-fibroin salting liquid (available zinc chloride, one or more mixture concentration 10-70 part such as the aqueous solution of potassium nitrate, sodium sulfocynanate)
Nonionic surface active agent 0-10 part
Optimum formula component (by weight) is:
600 parts of polyvinyl alcohol (20% the aqueous solution)
400 parts of silk-fibroins (20% NasCN salting liquid)
1 part of nonionic surface active agent
The manufacture method of silk-fibroin provided by the invention and polyvinyl alcohol blending fiber:
1. the preparation of spinning solution
By above-mentioned prescription weighing, polyvinyl alcohol added fill in the dissolvers of certain water, dissolving 2-6 hour in 90-100 ℃ of temperature range under agitation is made into concentration and is 25% the aqueous solution; The silk-fibroin adding is filled in the dissolvers of certain salting liquid, under agitation in 40-110 ℃ of temperature range, dissolved 1-8 hour.Then with polyvinyl alcohol water solution and silk-fibroin salt solution mix, more after filtration, deaeration makes spinning solution.
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 the 200-400 grams per liter, and the 300-800% that stretches in the plasticizing-bath of sodium sulphate or ammonium sulfate.
3. spinning post processing
Blended fiber after stretching is carried out HEAT SETTING handle under 200-280 ℃ of temperature, carry out chemical crosslinking with formaldehyde, crosslinking agent simultaneously, the time is 2-120 minute.
Silk-fibroin content＞25% of silk-fibroin of the present invention and polyvinyl alcohol blending fiber, with its dyeability of acid dyeing near silk, hygroscopicity is 8-10%, outward appearance, feel, gloss exactly like silk, intensity＞3CN/dtex, extend the answer of 20%, 3% specified elongation elasticity and reach more than 85%, it is a kind of thin,tough silk fiber type of high comprehensive performance.
The present invention has following advantage:
1. with silk-fibroin and polyvinyl alcohol salting liquid direct fabrics, simplify technological process, shortened production line, equipment investment is few, produces to be easy to control, and protein utilization is up to more than 90%, for the utilization of waste material in filature, silk spinning and the silk garment production, turn waste into wealth, opened up new useful approach.
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. by changing spinning, stretch, the Technology for Heating Processing condition makes the gloss of band salt spinning line spinning fibre reach the silk spinning level, has solved the shortcoming of band salt spinning line gained fiber gloss difference.
