Abstract
The invention discloses a cocoon cooking method for preparing high-quality grade-6A raw silk, which comprises the following steps: firstly carrying out vacuum infiltration on a silkworm cocoon by utilizing alkaline ionized water with a pH value of 7.5-8.5, then impregnating the silkworm cocoon subjected to the vacuum infiltration by utilizing acidic ionized water with a pH value of 4.5-6.5, cooking the impregnated silkworm cocoon in a machine and adding a certain amount of acidic ionized water at the low-temperature infiltration part. Compared with the background art, the cocoon cooking method has the advantages that a water molecular cluster of the alkaline ionized water is small, the surface tension is small, the infiltration is strong, the water is easy to enter an adhesive part of silk glue, so that the infiltration on a cocoon shell is uniform to be beneficial to improving the clean index of the raw silk; and as the silkworm cocoon subjected to the vacuum infiltration is impregnated by utilizing the acidic ionized water, the surface of the silkworm cocoon subjected to the vacuum infiltration is converted from alkalescence to neutrality or weak acidity so as to be beneficial to reducing the silk glue melting loss on the outer layer of the silkworm cocoon, thereby the cohesion indicator of the raw silk is improved. The cocoon cooking method has the advantages of simplicity, environment friendliness and no pollution.
Description
Technical field
The present invention relates to a kind of cocoons-boiling method of raw silk, specifically relate to a kind of cocoons-boiling method of preparing fine work 6A level raw silk.
Background technology
Silk industry is that after China's accession to WTO, minority can be dominated one of strong industry of international market, and China's raw silk and greig output account for respectively the more than 70% and 45% of Gross World Product, and export volume accounts for respectively 80% and 60% left and right of international market volume of trade.In existing national standard, the highest ranking of raw silk is 6A level, but in recent years, European client proposes to control requirement higher than the index of our national standard highest ranking 6A level raw silk to raw silk product.Such as: clean index 96 minutes, disconnect request 0 time, obvolvent index request 110 is inferior, and enterprise is by this raw silk called after fine work 6A level raw silk requiring higher than highest ranking.This technology trade requirement, owing to having surpassed the highest ranking of our national raw silk standard, has limited a lot of enterprise products and has exported to Europe, Japan, had a strong impact on take produce outlet silk class as the existence of main enterprise.Therefore, how to research and develop higher than highest ranking 6A level raw silk (fine work 6A level raw silk) in standard GB/T/T1797-2008 < < raw silk > >, for breaking foreign technology trade measure, improve filature enterprise right of speech and pricing right at home and abroad, significant.
In all indexs of raw silk of fine work 6A level, unapproachable index is mainly the clean index of raw silk and the obvolvent index of raw silk.And the clean index of raw silk is subject to outside the impact of the quality of raw material cocoon own, also there is direct correlation with cocoon cooking process, further after research, to find, the vacuum infiltration process in process of cocoon has obvious impact to clean index.But existing vacuum infiltration process to the deadlocked serious position osmosis of cocoon layer a little less than, silk gum swelling capacity is little, affect the raising of clean index, therefore, existing silk reeling technology is more difficult reaches the requirement of fine work 6A level raw silk to clean index, how to improve clean index and has become one of bottleneck of preparing in fine work 6A level raw silk.And use chemical assistant often when improving clean index, impact separate relax, other indexs such as reel silk from cocoons folding, and also can bring environmental pollution to a certain degree.
The obvolvent index of raw silk refers to that mat silk gum is bonding and boundling becomes the silk of raw silk, stands the complexity of division after repeatedly rubbing, and has reflected deadlocked firm degree between the silk that forms raw silk.The obvolvent index of raw silk is except outside the Pass itself having with raw material cocoon, and same and cocoon cooking process has very large relation.In process of cocoon, silk gum swelling is insufficient or cocoon cooking sericin dissolution is excessive, all will affect the obvolvent index of raw silk.And conventional cocoon cooking process will reach the obvolvent index of fine work 6A level raw silk, there is certain difficulty.Particularly clean index and obvolvent index reach the index request of fine work 6A level raw silk simultaneously, and difficulty is larger.
Summary of the invention
Problem for above-mentioned existence, the object of the present invention is to provide a kind of cocoons-boiling method of preparing fine work 6A level raw silk, to break existing cocoon cooking silk reeling technology to be difficult to reach require this technical bottleneck of fine work 6A level raw silk to cleaning, obvolvent index, improve the cleaning of raw silk, obvolvent index, makes its desired value reach the index request of fine work 6A level raw silk.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals:
1) adopt the alkali ion water (brine electrolysis) that pH is 7.5～8.5 to carry out vacuum infiltration to silk cocoon, infiltration temperature is normal temperature～40 ℃, and vacuum is 0.09 ~ 0.1 Mpa, and the speed of evacuation is 50-70 liter/second;
2) by the silk cocoon pH after vacuum infiltration, be 4.5～6.5 acid ion water retting 30～60 seconds, yet the silk cocoon after dipping is moved into cocoon cooking machine, enter the low temperature osmotic portion of cocoon cooking machine, cocoon cooking in beginning machine, and to utilize pH be that 4.5～6.5 acid electrolyzed functional water is as a part for the supplementing water of low temperature osmotic portion, the speed of splashing into is 1 l/h ~ 5.0 ls/h, to reduce pH to 7.0 ~ 6.8 of the low temperature osmotic portion water of cocoon cooking machine;
3) temperature of institute of low temperature osmotic portion water is 48 ~ 55 ℃; low after high before the temperature of cure bag adopts; temperature is 100～96 ℃; 54～62 ℃ of vapo(u)rizing temperatures; 54～62 ℃ of middle coolant-temperature gages, shake 48～56 ℃ of temperature, quiet 36～45 ℃ of the temperature of boiling; 25～35 ℃ of protection temperature, the cocoon cooking single-revolution time is 12 ~ 15 minutes.
4) by this cocoons-boiling method, the quality index such as the cleaning of the raw silk preparing, obvolvent surpass the raw silk of highest ranking 6A level index request in standard GB/T/T1797-2008 < < raw silk > >, solve the bottleneck problem of the 6A level raw silk that produces choice goods at present.
The present invention compared with prior art, has following beneficial effect:
1) vacuum infiltration cocoon cooking institute water is the alkali ion water of pH value 7.5-8.5.This ionized water is alkalescent, water clusters is little, surface tension is little, permeability is strong, and dissolving power is strong, easily enters the deadlocked part of weight of silk gum, thereby make the infiltration of cocoon layer even, improve the swelling performance of sericin within cocoon layer, reduced the impact of cocoon quality difference on filature quality, be conducive to improve the clean index of raw silk.
2) in ionized water generative process, except alkali ion water, also has acid ion, utilize the silk cocoon after acid ion water retting vacuum infiltration, make the surface of silk cocoon after vacuum infiltration change into neutrality or faintly acid by alkalescent, be conducive to reduce the outer field sericin dissolution of silk cocoon in process of cocoon, thereby improve the obvolvent index of raw silk.
3) solved in prior art, clean index and obvolvent index are difficult to reach a difficult problem for fine work 6A level raw silk index request simultaneously.
4) to be ordinary tap water enter effectively ionized groove to ionized water after purifying, and makes water generates ionization and the alkali ion water and the acid electrolyzed functional water that make, and needed raw material is with low cost, and preparation method is simple.
5) infiltration, with not adding any chemical assistant in ionized water, has solved because of auxiliary agent improper use, affects the problems such as reel silk from cocoons folding and silk quality, has the feature of environmental protection.
