Rear reel silk from cocoons: comprise except steps such as the moisture absorption of rough, little Yue silk sheet balance, little Yue vacuum, rereeling, great Yue silk sheet balance, arrangements, its medium and small Yue silk sheet balance and large Yue silk sheet balance all humidity be 75%, temperature carries out under being 26 DEG C of conditions; it is 16 hours that little Yue silk sheet balances, and it is 24 hours that large Yue silk sheet balances.
In above-mentioned silk preparation method, preferably, described cocoon cooking step comprises the steps: further
(1) preheating: by the preheating 1-2 minute under 60 DEG C of water temperatures of the silk cocoon after vacuum infiltration;
(2) boiling: by the boiling under 0.78-0.98Mpa steam pressure and 100 DEG C of temperature of the silk cocoon after preheating, boil cocoon layer and make cocoon chamber guttation;
(3) hot soup: cocoon cooking in the hot soup of 98 DEG C;
(4) shake: make noodle soup upheaval, drive cocoon grain to roll in cocoon cage, rub mutually;
(5) protect: cocoon cooking 1-2 minute in the warm water of 60 DEG C, makes outer silk gum suitably solidify;
(6) cocoon is gone out: water temperature is down to 40 DEG C, goes out cocoon.
In above-mentioned silk preparation method, preferably, in described boiling step, first silk cocoon is put into boiling in the first steam room, then is put into boiling in the second steam room, the steam pressure of the first steam room and the second steam room is 0.78-0.98Mpa, and temperature is 100 DEG C.
In above-mentioned silk preparation method, preferably, before high temperature steaming step, also step of selecting silkworm is comprised: carried out by size by silk cocoon separately.
Silk preparation method provided by the invention, by adopting high temperature steaming and vacuum infiltration, can make the cleanliness of the raw silk obtained higher.
Detailed description of the invention
The invention provides a kind of silk preparation method, it comprises the steps:
Select silkworm: silk cocoon is carried out by size separately.
High temperature steaming: process silk cocoon with saturated vapor in steaming room or steaming equipment, steaming temperature is 100 DEG C, and the time is 8-10 minute.Steaming can make sericin within cocoon layer transform to ease of solubility, and after steaming, cooked cocoon intergranular, the deadlocked power of intragranular are tending towards even, can increase substantially the cleanliness of raw silk.
Place: the silk cocoon after steaming is left standstill 18-26 hour at normal temperatures.
Vacuum infiltration: the method for the silk cocoon vacuum infiltration after placement is infiltrated, silk cocoon is absorbed water.Be specially, by physical method, air in silk cocoon extracted out, makes cocoon chamber become vacuum state, the silk cocoon of this state is placed in water, due to the existence of pressure reduction, cocoon chamber is absorbed water, thus reaches the object of cocoon layer osmotic absorbent.In this step, infiltration water temperature can be 35 DEG C-40 DEG C, and time of penetration is 5-10 minute, and vacuum is 0.05-0.1Mpa.Vacuum infiltration have cocoon chamber low, the pupal acid of water suction temperature leach less, be conducive to reducing internal layer fall thread, do the advantages such as thin pelettes, sericin dissolution are few.
Cocoon cooking: the silk cocoon after vacuum infiltration is carried out boiling in cocoon cooking equipment, makes the silk gum in silk cocoon obtain suitable swelling and be partly dissolved.Particularly, in the present invention, this cocoon cooking step comprises the steps: further
(1) preheating: by the preheating 1-2 minute under 60 DEG C of water temperatures of the silk cocoon after vacuum infiltration.
(2) boiling: by the boiling under 0.78-0.98Mpa steam pressure and 100 DEG C of temperature of the silk cocoon after preheating, boil cocoon layer and make cocoon chamber guttation.Particularly, first silk cocoon can be put into boiling in the first steam room, and then be put into boiling in the second steam room, the steam pressure of the first steam room and the second steam room is 0.78-0.98Mpa, and temperature is 100 DEG C.
(3) hot soup: cocoon cooking in the hot soup of 98 DEG C.
(4) shake: make noodle soup upheaval, drive cocoon grain to roll in cocoon cage, rub mutually, to draw thread silk before beating, increase new cocoon order rate.Shaking in process, adding cold water spray to protect silk gum.
(5) protect: cocoon cooking 1-2 minute in the warm water of 60 DEG C, makes outer silk gum suitably solidify, reach protection outer, stablize the object of silk gum, adjust cocoon ectonexine solution Diastolic Force, to adapt to filature requirement simultaneously.
(6) cocoon is gone out: water temperature is down to 40 DEG C, goes out cocoon.
Filature: by the silk dissociation of the silk cocoon after boiling, utilize silk gum to bond and couple together, making raw silk.In the present invention, under 40 DEG C of water temperatures, filature is carried out.
Rear reel silk from cocoons: rear reel silk from cocoons comprises except steps such as the moisture absorption of rough, little Yue silk sheet balance, little Yue vacuum, rereeling, great Yue silk sheet balance, arrangements, its medium and small Yue silk sheet balance and large Yue silk sheet balance all humidity be 75%, temperature carries out under being 26 DEG C of conditions; it is 16 hours that little Yue silk sheet balances, and it is 24 hours that large Yue silk sheet balances.
Silk preparation method provided by the invention, by adopting high temperature steaming and vacuum infiltration, can make the cleanliness of the raw silk obtained higher.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit.Those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present invention or surmount the scope that appended claims defines.
Although more employ steaming, vacuum infiltration, cocoon cooking, hot soup herein, shake, protect, filature, rear reel silk from cocoons, the term such as rereeling, do not get rid of the possibility using other term.These terms are used to be only used to describe and explain essence of the present invention more easily; The restriction that they are construed to any one additional is all contrary with spirit of the present invention.
