Description

Full real-silk dyed warp knit preparation process
Technical field
The present invention relates to silk textile technology field, more particularly to a kind of full real-silk dyed warp knit preparation process.
Background technology
Silk refers generally to silk, including mulberry silk, tussah silk, ricinus silk, cassava silkwormsilk etc., belongs to protein fibre, Contain 18 kinds of amino acid beneficial to human body in fibroin.Silk fiber is the thread fiber for uniquely obtaining practical application, by Silkworm changes mucus and solidifies.Silk fiber is a variety of because the feeding habits difference of silkworm is divided into, wherein have food mulberry leaf formed mulberry silk fiber, Eat the silk tussah fibre that mongolian oak leaf is formed and other wild silkworm silk fibers that food cassava leaves, Chinese coriaria leaf, castor leaf are formed；Mulberry silk Fiber and silk tussah fibre can remain into the form of filament fiber in the filament yarn of boundling formation, other several tussahs Fiber can only be staple fiber textile process by reshaping；In the filament yarn with mulberry silk fiber and the formation of silk tussah fibre boundling In, the filament yarn of mulberry silk fiber is most important, accounts for the major part of thread yarn.
The main component of silk is silk gum and fibroin, and silk gum about accounts for the 25%-30% of silk weight, and silk gum is wrapped in The outer layer of fibroin, plays a protective role to fibroin, has silk gum and impurity residual in the silk of silk cocoon reel silk from cocoons, can not only influence silk weaving Product coloring, and gloss, feel and the quality of silk goods can be influenced, therefore the silk gum of silk surface residual and impurity are necessary It is removed before dyeing；Fibroin and the principle of silk gum separation are that fibroin is not soluble in water, and silk gum has water solubility；Using acid, alkali, Soap, high temperature and pressure and enzymatic treatment are attained by the purpose of removal silk gum under certain condition.
The prior art can refer to the patent application document of application publication number CN106757384A, and it discloses a kind of elasticity is swollen Change the production method of silk quilt, including selects silkworm, cocoon cooking, degumming, removes pupa, lantern ring, silk braid, wire drawing, it is further comprising the steps of：A, it boils First cocoon is immersed in pure water before cocoon, water temperature be 50-70 DEG C, soaking time be 3-5 minutes, after the completion of immersion by cocoon with it is pure Water is put into vacuum tank and the alkaline swelling agent that pH value is 9-10 is added carries out boiling together, and boiling temperature is 90-100 DEG C, Digestion time is 5-10 minutes.B, after the completion by Silk Soaking in pure water, water temperature is 70-80 DEG C for wire drawing, and soaking time is 3-5 minutes, then again by Silk Soaking in the pure water for being placed with acid swelling agent, water temperature was 20-30 DEG C, soaking time 2- 4 minutes, by silk dry finishing finally to obtain the final product.
The principle of alkali boiling silk is the peptide bond that alkaline agent acts on sericin, makes its hydrolysis, which is non-specific , the amino acid of main function is cysteine, serine, threonine and arginine；After alkaline agent degumming, the average fibre of silk Degree can decline about 7dtex, and fracture strength, elongation at break and initial modulus can be declined, since the fiber number of silk is bright It is aobvious to reduce, flexibility, whiteness, glossiness and the feel of silk fabrics can be made all to be deteriorated.
The advantage of sour purifying method is easily controllable degumming rate in other methods, can carry out part degumming processing, but sour Refining cannot remove the impurity such as the grease on silk, require height to process equipment, and organic acid can be adsorbed by fibroin fiber, it is extremely difficult to It eliminates, influences the utilization of silk fiber；The advantage of soap purifying method is that the silk gum on silk can be made to dissociate, and prevents silk gum in silk On emulsification, the dispersion adhered to again, the fluffy degree, whiteness and glossiness of silk fabrics can be improved, but it is big to consume soap amount, production cost Height, usually time is long, is not suitable for uniform degumming；Addition of the high temperature and high pressure method without chemical reagent can be returned directly by refining liquid It receives silk gum to recycle, but the method needs high-temperature high-pressure apparatus, increases production cost；Enzyme purifying method environmental pollution is small, degumming It is small to the damage of silk limit, but the condition of enzyme effect is more complicated, the culture of zymogenic bacteria spends big, production cost height；Respectively Kind of method has pros and cons, therefore, how in silk refining processing to slough silk gum as far as possible, and reduce scouring processes as far as possible In damage to fibroin fiber, be a problem to be solved.
