Abstract
Tussah silk, tow dyeing technique, by come unstuck, bleaching, dyeing and scroop agent handle four procedures and form.Come unstuck by preliminary treatment (0.5～2 grams per liter aqueous sodium carbonate, 80～90 ℃), washing, enzyme boiling-off (1.5～2.5 grams per liter neutral enzymatic preparations, 45～50 ℃), washing, each step composition of soap boiling (1.5～2.0 grams per liter suds, 95 ℃).Bleaching (5.5～7.2 grams per liter H
2O
2, 60～85 ℃, bath raio 1: 30) after 3～4 hours, adopt active, neutral, acid dyeing (30～95 ℃), the control dyeing rate.Carry out the scroop agent at last and handle (concentration of aqueous solution 4～5 grams per liters, 40～50 ℃).Technology is reasonable, equipment is simple, easy operating; Product even dyeing, fastness height, lovely luster, graceful smooth.
Description
The invention belongs to and contain glue protein matter fiber bleaching and dyeing technique field.
Tussah is a big special product of China.The tussah silk product claims work in generation especially.Its output accounts for 80% of world wide production.The tussah long filament can be made into silk, and then makes clothing, and at home and abroad extensively sell in market, rather well received.Application as for the short silk of tussah then is restricted.This is that silk gum has very strong WATER REPELLENCY because contain silk gum in the tussah silk, therefore lacks not easy coloring of a tiffany that is processed into, tow with tussah, and dyefastness is low, and dye uniformity is poorer.
The objective of the invention is, contain the problem of silk gum, a kind of bleaching and dyeing technique that is specifically designed to tussah silk, tow is provided at the short silk of a tussah tiffany, tow.
Technical solution of the present invention is: at first to through piecing together, twist with the fingers, shake the processing of coming unstuck of the inthegum thin,tough silk, the tow that are processed into, bleach then, dyeing and scroop agent processing.That is the present invention by come unstuck, bleaching, dyeing and scroop agent handle four procedures and form.
One, comes unstuck
Come unstuck and form by giving processing, washing, enzyme boiling-off, washing and five steps of soap boiling.
Give processing, tussah silk, tow are put into given in the treatment trough, under 80～90 ℃ of temperature, soaked 40 minutes with 0.5～2 grams per liter aqueous sodium carbonate.
Washing will be put into sink through the tussah silk, the tow that give processing, extremely not have alkalescence (about 20 minutes) with 40～45 ℃ circulating water washing.
The enzyme boiling-off with 1.5～2.5 grams per liter neutral enzymatic (as 2079 neutral enzymatic) preparation, transfers to PH9-10 with aqueous sodium carbonate with enzyme preparation earlier, and boiling-off is 60～90 minutes under 45～50 ℃ of temperature.
The replenishment method of enzyme preparation is to add 1/2nd of last enzyme preparation consumption next time.Use 2 cubic metres of enzyme preparations as last boiling-off, the tussah silk of boiling-off identical weight next time, tow except that with the former enzyme preparation, are added one cubic metre of new enzyme preparation again.
Washing will be put into sink through tussah silk, the tow of enzyme boiling-off, with 40～45 ℃ of circulating water washing secondaries, again with cold water washing once.
Soap boiling will be through the tussah silk, tow of washing with 1.5～2.0 grams per liter suds soap boiling 20～25 minutes under 95 ℃ of temperature.Use 60～70 ℃ of water washings then once.
The purpose of giving processing in the degumming tech is, make silk gum fully expand, moistening, the penetrating power of enzyme when increasing the enzyme boiling-off is boiled effect thereby improve enzyme.Thereafter washing is that grease is washed off.
Two, bleaching
Therefore go back the residual fraction pigment on tussah silk after coming unstuck, the tow, be light brown, can dye after need bleaching processing.
The bleaching liquid component:
Hydrogen peroxide 5.5～7.2 grams per liters
4～5 milliliters/liter of the sodium metasilicate of 40 ° of Be '
988～990 milliliters/liter in water
60～85 ℃ of bleaching temperatures
Temperature-rise period is:
60 ℃ kept 20 minutes, were raised to 75 ℃ and kept 60 minutes again in 20 minutes, were warming up to 85 ℃ and kept 60 minutes again at 20 minutes, lowered the temperature naturally then.
PH value 8.5～9
Bleaching time 3～4 hours
Bath raio 1: 30
Float the back once, more once with 40～50 ℃ of flowing water washings with 80～85 ℃ of circulating water washings.
The bleaching process of extra white silk is, except that carrying out above-mentioned bleaching, also needs to carry out reducing bleach through sodium hydrosulfite (Hydros) or sulfur dioxide, urea.
Three, dyeing
The key of dyeing is the problem of dye leveller, also will control dyeing rate, to reach the purpose of levelling.
The characteristics of tussah silk, tow are that porous, milk yellow, pigment are also heavy, therefore should adopt active, neutral, ACID DYES.Dyestuff is soluble in water.
Dye the technical recipe of large red
1.8～2% of reactive brilliant red x-3b tussah silk, tow weight
Reactive brilliant red X-Uz " 0.3～0.35%
Salt 30 grams per liters
Soda ash 5～6 grams per liters
Dye dark-brown technical recipe
3～3.1% of neutral brown BL tiffany, tow weight
Neutral dark brown BRL " 1～1.2%
Neutral grey 2BL " 0.5～0.6%
2～2.5 milliliters/liter in thunder rice group
Glauber salt (Na
2SO
4) 2～3 grams per liters
During dyeing, the temperature of dyeing liquor is 30～90 ℃, and its temperature-rise period is to begin to heat up by 30 ℃, and 40 ℃ keep 10 minutes, 50 ℃ to keep 10 minutes, 65 ℃ to keep 10 minutes, 85 ℃ to keep 10 minutes, 95 ℃ to keep 30 minutes.
Four, the scroop agent is handled
Scroop agent (promptly crossing softener) is handled, and adopts Japan to produce scroop agent (model SKLE), and its concentration of aqueous solution is 4～5 grams per liters, and 40～50 ℃ of treatment temperatures are handled 15 minutes (immersion) time.
Advantage of the present invention is, technology is reasonable, flow process is short, equipment is simple, easy to operate.Come unstuck with the enzyme scouring process, can be with disposable the taking off of silk gum of tussah silk, thin,tough silk bundle; Adopt high-strength hydrogen peroxide bleaching efficiency height; Dye different colours and can adopt different dying material.Dyefastness can reach the ministry standard of textile stock-dye.GIFfany, tow lovely luster, uniformity, the product elegance is smooth.
In the enforcement, key is the strict degumming tech of carrying out, and can not take off fully as silk gum, and bleaching is difficulty just, and it is more difficult to dye.The key of bleaching is the concentration of hydrogen oxide, the addition and the bleaching temperature of stabilizing agent sodium metasilicate.The key of dyeing is the selection and the dyeing rate of dyestuff.The concentration of mainly choosing scroop agent model and controlling the scroop agent well is handled in the scroop agent.
