Description
Technical field
The present invention relates to a kind of weaving face fabric production method, especially a kind of production method of PHBV fabric.
Background technology
Copper ammonia fibre is a kind of regenerated celulose fibre, it is dissolved in the liquor ammoniae fortis of Kocide SD or alkaline cupric salt by natural cellulosic feedstocks such as cotton linters, be made into spinning solution, in coagulating bath, cuprammonium fibroin molecular chemistry thing disintegrating and regeneration goes out cellulose, and namely the hydrate cellulose of generation obtains ammonia copper wire through aft-loaded airfoil.The copolymer of PHBV and new bio macromolecule 3-hydroxybutyrate ester and 3-hydroxyl valerate, it is one starch is raw material, uses the biomaterial that fermentation engineering is produced.Be a kind of Biopolvester, it is produced by bacterium, by bacterial digestion, can be decomposed into carbon dioxide, water and living beings completely under soil or Composting condition.PHBV fiber is a kind of low energy consumption product, ratio oil product is the low 30%-50% energy consumption of polymer that raw material is produced, and has submissive sense of touch with the fabric that this fiber is made, graceful gloss, be similar to the quality of real silk, but far win true silk products in intensity, DIMENSIONAL STABILITY.Due to the transformation of fashion's culture, the concept of fast dress ornament is popular in the world, fast dress ornament is exactly per release multiple different latest fashion season fast every year, the dress in consumer's annual per season is all not quite similar, this consumption concept can seize a large amount of profits for garment enterprise, but the clothes that consumer buys often only is worn some months and has not just again been worn, and causes a large amount of wastes like this.What the clothes of current most of fast dress ornament style was used is all by oil product is the polymer that raw material is produced, and this fiber degradation difficulty, production cost is not low.Garment enterprise needs a kind of fabric being suitable for fast dress ornament concept now for this reason, and it is low that it should have production cost, environmentally friendly, and rapidly, feel is excellent in degraded, the feature that intensity is applicable to.Copper ammonia fibre and PHBV fiber are all biodegradable fibers, and the blended yarn woven fabric of copper ammonia fibre and PHBV fiber is a kind of highly desirable fast dress ornament concept fabric.But differing greatly of these two kinds of fibers, the regain of copper ammonia fibre only has about 0.5% in the regain of about 11%, PHBV fiber, and the fracture strength of copper ammonia fibre is that the fracture strength of 15-20cN/tex, PHBV fiber is at about 25cN/tex.
DENIER is fibre (carefully) the degree unit of silk, and refer to the quality grams of fiber when official regain that 9000m is long, unit is the dawn.
The rate of sizing: after starching through the dry pulp of yarn heavily to the percentage of warp thread dry weight former before starching.
Summary of the invention
The present invention is directed to deficiency of the prior art, provide the production method of a kind of cuprammonium and PHBV blended yarn woven fabric, the fabric that the inventive method is produced is with low cost, and degradable degree is high, 5 to 10 years just can be degradable after generally discarding.This fabric has submissive sense of touch simultaneously, and graceful gloss, is similar to the quality of real silk, but far wins true silk products in intensity, DIMENSIONAL STABILITY, is a kind of fabric products being applicable to very much fast dress ornament concept.
