Abstract
The invention discloses a method for increasing the whiteness degree and improving the softness of raw silk formed by fresh cocoon silk reeling. The method includes the steps that fresh cocoons are stacked and stored, and then sequentially mixed, stripped, and sorted according to technology requirements, so that silk reeling cocoons are obtained; the silk reeling cocoons are placed in an airtight water tank and permeated by low-temperature water in a suction mode; after permeation by the low-temperature water in the suction mode, silk reeling is performed on the permeated water-absorption silkworm cocoons through an automatic silk reeling machine, and silk reeling water is kept clear, or replaced with clear water; small nets are placed in the water tank, absorb water through negative-pressure water entering, and then are soaked, and meanwhile additives are adopted for treatment; finally, re-reeling, arranging, skein twisting and packaging are performed. The method has the advantages of being simple, rapid and low in cost, and is beneficial to overcoming the defects in existing fresh cocoon silk reeling, solving the problems that raw silk is not soft enough in hand feeling, the surfaces of the raw silk are rough, and the color of the raw silk is not uniform, so that the performance of the raw silk is affected, and improving the quality of the fresh cocoon raw silk.
Description
Technical field
The present invention relates to a kind of fresh cocoon processing method, especially relate to a kind of method improving fresh cocoon reeling raw silk whiteness and flexibility, improve fresh cocoon reeling raw silk quality.
Background technology
Fresh cocoon raw silk is the raw silk adopting the direct reel silk from cocoons system of fresh cocoon.Fresh cocoon reeling does not need cocoon drying and cocoon cooking engineering, decreases throwing link, reduces filature cost; Fresh cocoon reeling engineering, steam use amount reduces, and has saved the energy; And the using value of fresh silkworm chrysalis is high, also improve the utilizing status of silkworm chrysalis accessory substance.Fresh cocoon raw silk due to heat-treated less, the style of natural raw silk uniqueness can be kept preferably.
At present, invention (method [P] of fresh silkworm cocoon one step filature, the ZL03118854 of the patent of fresh cocoon reeling aspect mainly Bai Yanchuan, Liu Huifen, Zou Fangqing, Tan Zhihu, 2006), first by fresh cocoon freeze preservation, mixed stripping screening, vacuum drainage permeates, automatic silk reeling, winding shaping.This process simplify silk reeling technology, decrease cocoon drying, cocoon cooking engineering, economize energy, is adopt more fresh cocoon reeling method at present.But the method and other improve one's methods, also there is problem affect raw silk quality deficiency, as raw silk feel is soft not, Raw Silk Surface is coarse, is comparatively difficult to the raw silk of reel silk from cocoons high-grade grade, affects the aft-loaded airfoil productions such as silk weaving production and printing and dyeing.
Summary of the invention
For the deficiency that current fresh cocoon reeling and fresh cocoon raw silk exist, the present invention proposes a kind of method improving fresh cocoon reeling raw silk whiteness and flexibility, that one can overcome the deficiencies such as fresh cocoon reeling raw silk feel is soft not, Raw Silk Surface is coarse, silk gum particle packing, with the silk reeling method of dried cocoon raw silk similar nature, improve fresh cocoon raw silk quality, solve the technical barrier having a strong impact on raw silk performance that current fresh cocoon reeling exists, promote the development of silk industry, to producing play directive function to filature, silk weaving.
The present invention's adopted technical scheme that solves the problem comprises the following steps:
The technical process of fresh cocoon reeling of the present invention is: fresh cocoon → (refrigeration, freezing or do not refrigerate, not freezing) → mixed stripping selects silkworm → water at low temperature suction infiltration → water at low temperature automatic silk reeling → impregnation process → skein finishing → hank knotting packs.
Specifically comprise the following steps:
1) carrying out stacking storage purchasing the fresh silk cocoon entered the station, 1 can be deposited according to actual needs to time several months;
2) the fresh silk cocoon stacking storage, according to production engineering specifications, carry out mixed cocoon, stripping cocoon successively, select silkworm, obtain filature cocoon;
3) filature cocoon is put into airtight tank, carry out water at low temperature suction infiltration 4 ~ 8min, vacuum is 0.08 ~ 0.1MPa, water temperature 40 ~ 60 DEG C, and the water surface exceeds silk cocoon 4 ~ 6cm;
4) the osmotic absorbent silk cocoon after water at low temperature suction infiltration, automatic silk reeling machine is adopted to carry out filature, beating soup temperature is 60 ~ 80 DEG C, filature soup temperature is 30 ~ 34 DEG C, pH value 6.8 ~ 7.7, filature soup is kept clear soup, except normal Inlet and outlet water, when finding that filature soup turns yellow, is replaced by clear water in time; Croisure length 80 ~ 110mm, twists with the fingers sheath number 90 ~ 120; ， little Dragnet winding shaping under 40 DEG C of conditions, winding speed 180 ~ 230 r/min;
5) little Dragnet is put into tank, first carry out negative pressure water inlet water suction, then impregnation process, and carry out auxiliary agent process simultaneously;
6) last skein finishing, hank knotting is packed.
Described step 1) is purchased the fresh silk cocoon entered the station and is put into plastic crate or bamboo basket, under normal temperature condition, stack storage.
Described step 1) purchase the fresh silk cocoon entered the station put into plastic crate move into freezer stack, under 0 ~ 6 DEG C of temperature conditions cold storing and fresh-keeping storage.
Described step 1) purchase the fresh silk cocoon entered the station put into plastic crate move into freezer stack, under-1 ~-20 DEG C of temperature conditions, carry out freeze preservation storage.
Described auxiliary agent process adopts soft treatment or form and aspect to improve process, and wherein the auxiliary agent of soft treatment adopts commercially available conventional raw silk softener, and the auxiliary agent that form and aspect improve process also adopts commercially available raw silk to commonly use brightening agent.
The pressure of the negative pressure in described step 5) is 0.053 ~ 0.067MPa.
The present invention compared with prior art, has the following advantages and effect:
The present invention utilizes fresh cocoon Preservation Treatment, and low temperature osmotic, low temperature filature, assurance croisure length and twisting count, impregnation process etc., be optimized process conditions and process by explorative experiment, carry out fresh cocoon reeling, produces and obtain high-quality raw silk.
The advantage that the present invention has simply, quick, cost is low, is conducive to the deficiency overcoming the existence of existing fresh cocoon reeling, and solution raw silk feel is soft not, Raw Silk Surface is coarse, silk look disunity etc. affects the drawback of raw silk performance, improves fresh cocoon raw silk quality.
