Abstract
The present invention provides a method for processing the bulk fiber of soybean fiber, which comprises the steps of the pretreatment of boiling or bleaching soybean fiber, dyeing the soybean fiber, the post-treatment of the soybean fiber, drying the soybean fiber, etc. The dyeing step uses an active dye, and the dye is proportioned according to different color requirements. A chelating dispersing agent, anhydrous sodium sulfate and calcined soda are added into a dying vat; then water washing operation is carried out, and acetic acid glacial is added for neutralization; in soaping operation, a detergent is added, and then the color fixing and softening treatment is carried out. The method of the present invention can carry out the production without special equipment, and is particularly suitable for the production of medium and small-size enterprises of which the scale is not large. The soybean fiber produced by the method of the present invention has the advantages of brilliant colors, various colors, soft hand feeling, full luster, good heat insulating ability, high strength and elongation, fluffiness, low vat difference and high producing stability. The present invention solves the problems of loose colors, color fade, color adhesion, color aging, etc., particularly the difficult problem that the soybean fiber has natural yellow. The present invention provides bright and colorful garments and face fabrics for the market.
Description
Technical field
The present invention relates to a kind of colouring processing method of soybean fiber loose-stock, particularly a kind of dyeing that uses the soybean fiber loose-stock of REACTIVE DYES.
Background technology
Protein and polyvinyl alcohol content are respectively 23%～55% and 45%～77% in the composition of fibre and soya, so soybean fiber has the mechanical property of chemical fibre and synthetic fiber, contain the performance of natural silk again.And fibre and soya has far infrared, antiultraviolet and antibacterial functions, fibre and soya is soft, gloss is soft, full and warm property is strong, strength and elongation is higher, antistatic property is better than characteristics such as synthetic fiber; adopt petroleum resources because of traditional chemical fibre is most; energy scarcity and power of regeneration difference and cycle are long; for energy savings; the protection ecological resources; adopt fibre and soya to draw materials easily; power of regeneration is strong; cycle is very short again; superior performance; more and more paid attention to by people, the exploitation dyeing processing technique is very necessary.
In Chinese patent CN-91112719, disclose a kind of colouring method of bulk cotton fibres, but this dyeing only is to adopt direct dyeing, and just dyes cotton, be not suitable for loose stock dyeing, have bigger limitation other kind.
Summary of the invention
The object of the present invention is to provide a kind of processing method of soybean fiber loose-stock, traditional technology of spinning after stain is earlier made into the technology of spinning after the reactive dyeing, solved the natural yellow difficult problem of fibre and soya, for market provides gorgeous colorful clothes and lining, and meet environmental protection requirement.
For achieving the above object, soybean fiber loose-stock processing method of the present invention comprises the pre-treatment (boiling-off or bleaching) to fibre and soya, dyeing, post processing, steps such as oven dry.Adopt REACTIVE DYES in the described dyeing, according to different color and luster requirements, the dye ligand ratio, in dye vat, add chelated dispersants, glauber salt, soda ash, dyeing is 30～60 minutes in the time of 60～70 ℃, washes room temperature then, adds glacial acetic acid and neutralizes, pickling 10 minutes, when soap boiling, add detergent, be warming up to 80～90 ℃ with 1～3 ℃ of speed of per minute, soap boiling 15 minutes, soap boiling 1～3 time, washing is cooled to below 50 ℃, adds color fixing agent Y and softener cws and carries out the fixation soft treatment, and the time is 8～12 minutes.
A kind of improvement as the inventive method, described pre-treatment process is a boiling-off technology, the step of this boiling-off technology comprises that adding bath raio at normal temperatures is in 5～20 the water, add 2～3 grams per liter chelated dispersants and 2～3 grams per liter soaping agents, directly be warming up to 80～90 ℃, be incubated 30～60 fens kinds, dye after cooling to the temperature that dyeing needs again.
Another kind as the inventive method improves, described pre-treatment process is a bleaching process, this bleaching process step comprises that adding bath raio at normal temperatures is in 5～20 the water, adding 2～3 grams per liter chelated dispersants and 30g/L concentration are 27.5% peracetic acid, regulate PH=7 with NaOH, hydrogen peroxide stabilizer sodium metasilicate 3g/L, be warming up to 60～70 ℃ with 1～2 ℃ of speed of per minute, be incubated 30～60 fens kinds, the raffinate of draining was washed 10 minutes, add deoxidation enzyme 2～4g/L, 10 fens kinds of 40 ℃ of insulations washs 10 fens kinds, dye after cooling to the temperature of dyeing needs again.
As improving again of the inventive method, described aftertreatment technology step be included in 45 ℃～60 ℃ down in and 10～15 minutes, adding 0.4～0.8 grams per liter concentration is 98% glacial acetic acid, then under 80 ℃～90 ℃, soaped 10～20 minutes, the soaping agent that adds 2 grams per liters was washed 5～10 minutes 45 ℃～60 ℃ heat, looked shade and did 1～2 time, under 45 ℃～60 ℃, carried out the fixation soft treatment 10～20 minutes at last, the softener of last 2～5 grams per liters behind the color-fixing agent of adding 2～3 grams per liters.
The inventive method does not need special installation just can produce, be particularly suitable for small medium-sized and small enterprises production, fibre and soya by the inventive method production, bright-colored, color is various, soft, gloss is plentiful, warmth retention property good, strength and elongation is high, fluffy, the cylinder difference is little, production stability is high, and solved loose colour, faded, problems such as staining, look old degree, most critical be to have solved the natural yellow difficult problem of fibre and soya, for market provides gorgeous colorful clothes and lining.
The specific embodiment
Further specify the present invention below in conjunction with specific embodiment.
Embodiment one
Select 200 kilograms of soybean fiber loose-stocks for use, put into bath raio at normal temperatures and be 1: 8 and contained the solution of the chelated dispersants of 2 grams per liters, 2～3 grams per liter soaping agents are warmed up to 85 ℃ of insulations 30 minutes, bleed off pin water, and the water overflow is clean.Adopt REACTIVE DYES, according to different color and luster requirements, the dye ligand ratio, poured dyestuff and 1/5 glauber salt into the dye vat material together 15-20 minute, normal temperature running 30 minutes, be warmed up to the required temperature of dyestuff with 1 ℃/minute then, select the suitable alkali rate curve that adds to add liquid caustic soda, add alkali speed and want slow earlier back fast according to different dye characteristics, be 40 minutes add-subtract time, hold the temperature 15 minutes with regard to discharge opeing, post processing is included under 50 ℃, in and 10 minutes, add 0.8 grams per liter glacial acetic acid (concentration is 98%), then under 85 ℃, soaped 20 minutes, add the soaping agent of 2 grams per liters, under 60 ℃, heat was washed 5 minutes, look shade and be 1-2 time, at last under 50 ℃, fixation soft treatment 20 minutes, add behind the color-fixing agent of 2 grams per liters and 2 grams per liter softeners, dry afterwards.
