Description
Technical field
The present invention relates to the processing method of a kind of tussah cocoon shell, specifically cocoon case degumming malleation pre-treating method.
Background technology
Tussah silk is made up of sericin and fibroin, and sericin is wrapped in fibroin, and fibroin accounts for 84%, and sericin accounts for about 12% ~ 16%, containing waxiness pigment and the inorganic matter of about 2.5%.Sericin, fibroin are all made up of protein and aminoacid, and sericin is wrapped in fibroin outer layer.Normally utilize silkworm silk spinning, weaving cotton cloth needs to take off sericin, and this scouring processes is refine.The most traditional method of refining is exactly soap alkaline process, and the principle of soap alkali chemical Degumming is to utilize sericin and fibroin to remove sericin for the stability of alkali, the difference of sensitivity, and sericin is easily hydrolyzed soluble in water compared with fibroin, removes through washing.Traditional soap alkali chemical method degumming tech, major defect is that degumming is irregular, and deoiling effect is poor, and the loss of strength of silk fiber is big, water consumption, and power consumption is polluted environment, is the technique of a class resource high consumption.The 1980s, people start the research of enzyme preparation degumming, and 2709 alkaline proteases are used for natural silk degumming relative maturity.Due to sericin four-layer structure, getting over fibroin internal layer, structure is the tightst, so before protease degumming, carry out permeating, swelling pretreatment.At that time, this pretreatment still uses a small amount of soap oxygenation pretreatment, 2709 alkaline proteases, needs in the experienced pendular ring border of alkalescence, competence exertion useful effect.So this degumming mode simply makes certain contribution in terms of degumming effect, reduction energy resource consumption, but owing to using alkali liquor, still environment is caused the biggest pollution, do not reach ecology, the requirement of environment-protecting clean production.No matter the degumming of tussah cocoon shell, use any medium, the most all tussah cocoon shell must be carried out pre-treatment.The method of its pre-treatment is different, and the effect of degumming is the most different.
Summary of the invention
For the deficiency on existing tussah cocoon case degumming preprocessing technical method, the present invention provides the loss of strength of a kind of silk fiber little, the energy-conservation and tussah cocoon case degumming malleation preprocessing technical method of nonpollution environment.
The concrete technical measures solving the problems referred to above are: a kind of tussah cocoon case degumming malleation preprocessing technical method, it is characterized in that:
Tussah cocoon shell after remove impurity, in terms of mass parts, 100 parts load mesh pocket, put in high-temperature high-pressure tank, water filling 1000 ~ 1200 parts, close gland in high-temperature high-pressure tank, it is passed through steam, being warming up to steam pressure 0.15 ~ 0.25 MPa, digestion time 60 ~ 120min, pressure release is to normal pressure, open tank body gland, bag taking, room temperature washing 5 ~ 8min, centrifuge dewatering.
Beneficial effects of the present invention:Tussah cocoon case degumming preprocessing technical method, use High Temperature High Pressure steaming and decocting, 1/4th are shortened than the existing process time, without any additive, environmentally safe, integrated cost is only and has 1/3rd of technique, Antherea pernyi Guerin-Meneville fiber is not resulted in any damage, make Antherea pernyi Guerin-Meneville fiber softening, fluffy, enhance fiber glossiness.
Detailed description of the invention
Embodiment 1
24 kilograms of tussah cocoon shell after remove impurity loads mesh pocket, puts in high-temperature high-pressure tank, and water filling 240 kilograms, close gland in high-temperature high-pressure tank are passed through steam and heat up, keep steam pressure 0.15 MPa, time 120min.The positive pressure method process time is determined by steam pressure, and steam pressure is the biggest, processes the time the shortest, when more than 0.25 MPa, processes the time little on result impact, but the height that consumes energy, production security is poor, therefore should not utilize more than 0.25 MPa.
Pressure release, to normal pressure, opens tank body gland, bag taking, and normal-temperature water is rinsed 8 minutes, is dehydrated 7 minutes.
Pre-treatment effect, uses sensory test method routinely, i.e. easily tears apart with hands.Carry out the tussah cocoon shell of pre-treatment as stated above through degumming process, the silk tussah fibre meeting company standard can be obtained.
Embodiment 2
Feed intake: in high-temperature high-pressure tank, put into 24 kilograms of tussah cocoon shell, 260 kilograms of water, heat up, keep steam pressure 0.2 MPa, time 90min.Being depressurized to normal pressure, open cover, take tussah cocoon shell, normal-temperature water is rinsed 5 minutes, is dehydrated 7 minutes.
Embodiment 3
Feed intake: in high-temperature high-pressure tank, put into 24 kilograms of tussah cocoon shell, 284 kilograms of water, heat up, keep steam pressure 0.25 MPa, time 60min.Being depressurized to normal pressure, open cover, take tussah cocoon shell, normal-temperature water is rinsed 6 minutes, is dehydrated 7 minutes.
Claims (1)
1. a tussah cocoon shell treatment technique method application before degumming malleation, is characterized in that: 24 kilograms of the tussah cocoon shell after remove impurity loads mesh pocket, puts in high-temperature high-pressure tank, water filling 260 kilograms in high-temperature high-pressure tank, close gland, is passed through steam and heats up, keep steam pressure 0.2 MPa, time 90min, pressure release, to normal pressure, opens tank body gland, bag taking, normal-temperature water is rinsed 5 minutes, is dehydrated 7 minutes.
