Abstract
The present invention belongs to a technical method of filature industry silkworm cocoon spinning, which relates to the degumming of silk and bleaching processing technology of silkworm cocoons. The present invention is characterized in that the present invention comprises the following process steps: preparing a degumming solution, soaking silkworm cocoons and steaming by adding steam for 20 minutes, solution separation, clear water rinse, dehydration, preparing a bleaching solution, soaking silkworm cocoons and steaming by adding steam for 40 minutes, solution separation, clear water rinse, dehydration, preparing a silk protection solution, washing for 30 minutes in a swinging mode, solution separation and baking. The degumming of silk and bleaching processing technology of silkworm cocoons of the present invention can shorten the time of degumming of silk of silkworm cocoons from 24 hours to 20 minutes. The cocoon fiber bleaching is uniform, and the silk corrosion is slight. The present invention has bright and smooth silk and no silkworm cocoon smell after protected and processed by the silk protection solution.
Description
Technical field
The invention belongs to the filature industry silk cocoon technical method that reels off raw silk from cocoons, relate to a kind of silk cocoon degumming of silk, bleaching and treating process.
Background technology
Domestic, to reel off raw silk from cocoons be to adopt buck to boil to come unstuck-technology of hydrogen peroxide bleaching to silk cocoon always for many years, because this technology alkali concn height, silk processing time length in alkali lye needs 24 hours, not only reduce production efficiency, and alkali lye is serious to the erosion of silk, has influenced the performance and the result of use of silk.
Summary of the invention
The present invention has overcome the defective of above-mentioned existence; purpose is in the silk cocoon drawing process; adopt degumming baths, bleaching liquid and protection liquid to replace soda ash, hydrogen peroxide liquid processing silk cocoon; to alleviate silk cocoon silk suffered must erosion in the process of coming unstuck; shorten the processing time; enhance productivity, a kind of silk cocoon degumming of silk, bleaching and treating process are provided.
Silk cocoon degumming of silk of the present invention, bleaching and treating process content Description:
Silk cocoon degumming of silk of the present invention, bleaching and treating process is characterized in that: its processing step is:
(1), preparation degumming baths: the degumming baths prescription is to be pivot weight unit preparation with the 50kg silk cocoon: water 50kg, sodium carbonate 1.5kg, sodium metasilicate 1.2kg, mercerising soap lye 0.2kg stir after mixing and make degumming baths;
(2), degumming baths is put into vapor can, silk cocoon is put into the degumming baths dipping, adds steamed 20 minutes from pot bottom; Pull silk cocoon out and take off liquid in centrifuge, the silk cocoon that will take off behind the liquid was put into the clear water reserviors rinsing 5 minutes, pulled silk cocoon and centrifugal dehydration after the rinsing out;
(3), preparation bleaching liquid: the bleaching liquid prescription is to be pivot weight unit preparation with the 50kg silk cocoon: the hydrogen peroxide 25kg of water 50kg, sodium carbonate 0.5kg, sodium metasilicate 0.5kg, NaOH 0.5kg, concentration 27% stirs after mixing and makes bleaching liquid;
(4), bleaching liquid is placed in the vapor can, put into the silk cocoon that dewatered and added steamed 40 minutes, pull silk cocoon out and in centrifuge, take off liquid, silk cocoon was put into the clear water reserviors rinsing 5 minutes, pull silk cocoon and centrifugal dehydration out from pot bottom;
(5), preparation silk quality protection liquid: silk quality protection formula of liquid is to be the preparation of pivot weight unit with the 50kg silk cocoon: temperature is 40 ℃ water 1000kg, glacial acetic acid 0.4kg, softener 2kg, stirs to make silk quality protection liquid after mixing;
(6), protect liquid to be placed in the vapor can silk quality, put into the silk cocoon pendulum that has dewatered and washed 30 minutes, pull out and centrifugal dewatering, send into the hothouse oven dry.
The main component of mercerising soap lye is: 12-sodium alkyl benzene sulfonate, glycerine stearate and urea.
Adopt silk cocoon degumming of silk of the present invention, bleaching and treating process, can make the silk cocoon degumming of silk time shorten to 20 minutes by 24 hours; The silk bleaching is even, and the silk quality corrosion is very light, and after liquid protection processing was protected in the organizine quality guarantee, the silk quality light was smooth and do not have silk cocoon to distinguish the flavor of.
The specific embodiment
Silk cocoon degumming of silk of the present invention, bleaching are handled and to be achieved in that in the single treatment amount is the vapor can of 50kg silk cocoon volume and to carry out, and water intaking 50kg, sodium carbonate 1.5kg, sodium metasilicate 1.2kg, mercerising soap lye 0.2kg stir after mixing and make degumming baths; The 50kg silk cocoon is put into degumming baths flood, added steamed 20 minutes from pot bottom; Pull silk cocoon out and take off liquid in centrifuge, the silk cocoon that will take off behind the liquid was put into the clear water reserviors rinsing 5 minutes, pulled silk cocoon and centrifugal dehydration after the rinsing out.
The hydrogen peroxide 25kg of 50kg, sodium carbonate 0.5kg, sodium metasilicate 0.5kg, NaOH 0.5kg, the concentration 27% of fetching water again makes bleaching liquid; Bleaching liquid is placed in the vapor can, puts into the silk cocoon that dewatered and added steamed 40 minutes, pull silk cocoon out and in centrifuge, take off liquid, silk cocoon was put into the clear water reserviors rinsing 5 minutes, pull silk cocoon and centrifugal dehydration out from pot bottom.
And then to get temperature be 40 ℃ water 1000kg, glacial acetic acid 0.4kg, softener 2kg, stirs after mixing and make silk quality protection liquid; Protect liquid to be placed in the vapor can silk quality, put into the silk cocoon pendulum that has dewatered and washed 30 minutes, pull out and centrifugal dewatering, send into hothouse oven dry aftertreatment technology and finish.
Mercerising soap lye of the present invention is produced and is sold by the big magnificent chemical company in Dalian, and the main component of mercerising soap lye is: 12-sodium alkyl benzene sulfonate, glycerine stearate and urea.Its molecular structure belongs to the composite construction of organic matter and inorganic matter.In a certain proportion of solution, can play dissolution to water-fast grease type organic in the silk.Since the decision of the inorganic matter constituent in the mercerising soap lye its can be water-soluble, so can make silk gum and the grease in the silk can be water-soluble fast, have accelerated the process of coming unstuck.Again because urea components is arranged in soap lye, in processing procedure in urea and the silk gum contained formaldehydes material to be combined into lipid material water-soluble and separate from silk, make that content of formaldehyde is close to zero in the silk, usually time can shorten to more than 20 minute.
