A kind of pre-treatment processing technology of silk flosssilk wadding
Technical field
The present invention relates to textile technology field, the pre-treatment processing technology of specifically a kind of silk flosssilk wadding.
Background technology
Silk floss is that the floating silk on a kind of damaged cocoon and cocoon shell surface is raw material (including continuous, the double palace silk flosses of pelettes etc.), by essence
Practice, dissolve silk gum, garnetting fiber and be made.Its warmth retention property is good, can make clothing wadding and is used by wadding.The white silk of silk floss in traditional handicraft
Drift process includes degumming, bleaching twice technique.Degumming and bleaching are to be completed in two self-contained process respectively, therefore operation is numerous
Multiple, equipment flowing water line length, energy consumption is big;The activity duration is long again, and silk is de- to damage big, low production efficiency;Containing a large amount of in its working solution
Alkali, bleaching agent, silk it is de- etc., the wastewater environment of discharge is seriously polluted, and intractability is high.
Although degumming, bleaching twice technique to be merged into the technique of step completion in the prior art, exist and use
Chemical assistant it is many, the contaminated wastewater of discharge is serious, and the removal effect of impurity in silk floss after processing, grease is undesirable, silk
De- loss is big, and fibre damage is serious, and silk floss color and luster is partially yellow, and the problems such as pliability is relatively low, therefore the factory for really using now is simultaneously
Seldom.
For example:A kind of disclosed patent of invention " manufacture method of pelettes silk quilt " (application number 201410585989.7),
Working solution is according to 1 in above invention:25~30 bath raio, the continuous piece that will be extracted is put into refining agent, is protected at 97 DEG C~99 DEG C
Micro- fluidized state is held 110~160 minutes, wherein the refining agent is made up of the following ingredients represented with concentration expressed in percentage by weight:
0.1%~0.2% Na2CO3,0.3%~0.5% waterglass, 0.32%~0.48% AEO,
0.08%~0.12% alkyl phenol ethylene oxide condensation product and water composition, complicated component, process time is long, and the de- loss of silk is big,
Fibre damage is serious, and treatment effect is general.
The content of the invention
The present invention employs the synthetic operation system of biotechnology and chemicals technology to overcome the deficiencies in the prior art,
New processing route is devised, on the basis of refining, one step of bleaching are completed, the use for reducing chemical assistant is realized, reduced
Treatment temperature, shortens process time, considerably reduces water, electricity, the consumption of vapour equal energy source, reduces discharge of wastewater, effectively carries
Production capacity high and product quality, have truly accomplished clean manufacturing, energy-saving and emission-reduction.
To achieve the above object, design a kind of pre-treatment processing technology of silk flosssilk wadding, including refining, bleaching process flow and in
With, plus soft technology flow, it is characterised in that:Specific processing technology is as follows:
(1) refining, bleaching process flow:
