Abstract
The invention discloses a kind of real silk fabric low temperature pre-treating method, comprise the following steps：1. Alkaline pretreatment；2. warm water is washed；3. cold water is washed；4. acid protease degumming；5. warm water countercurrent rinsing；6. shaping, dry.The present invention can realize the efficient degumming of real silk fabric at a lower temperature, so as to improve each side quality of real silk fabric.
Description
Technical field
The present invention relates to a kind of real silk fabric low temperature pre-treating method, belong to weaving processing technology field.
Background technology
The conventional method of silk fabric dyeing is to carry out degumming using soap alkaline process, and the temperature that alkali degumming needs is higher, except easy
Cause fibroin yellowing, damage outer, it is dynamic due to practicing liquid boiling, it can make to produce friction between silk and cause the defect such as scratch, scared, dye
Also color spot is easily formed during color.Therefore occur many production works concise to real silk fabric progress using biological enzyme technology at present
Skill, although the problem of this technique can carry out a certain degree of degumming at a lower temperature, and bioenzyme activity is unstable
Cause degumming less efficient, the stability of product can not be ensured.
The content of the invention
It is an object of the present invention to provide a kind of real silk fabric low temperature pre-treating method.It can be real at a lower temperature
The efficient degumming of existing real silk fabric, so as to improve each side quality of real silk fabric.
Technical scheme：A kind of real silk fabric low temperature pre-treating method, is characterized in, comprises the following steps：
1. Alkaline pretreatment；
2. warm water is washed；
3. cold water is washed；
4. acid protease degumming；
5. warm water countercurrent rinsing；
6. shaping, dry.
In above-mentioned real silk fabric low temperature pre-treating method, the step 1. the middle alkali lye used include 1.8g/L soda ash,
The bath raio of 6g/L industrial soaps, 4.5g/L sodium silicates and 0.4g/L sodium hydrosulfites, real silk fabric and alkali lye is 1:50, Alkaline pretreatment
Temperature is 75 DEG C, and pH keeps 9.5~10.5,50~70 minutes processing times.
In foregoing real silk fabric low temperature pre-treating method, the washing temperature of the step 2. is 50 DEG C, and the time is 15 points
Clock.
In foregoing real silk fabric low temperature pre-treating method, the washing temperature of the step 3. is 15~30 DEG C, and the time is
30 minutes.
In foregoing real silk fabric low temperature pre-treating method, 4. the step uses acid protease degumming liquid, acid egg
White enzyme degumming liquid include 40~60g/L acid proteases, and the bath raio of real silk fabric and acid protease degumming liquid is 1:50, processing
Temperature be 45 DEG C, pH keep 4.5~5,80~90 minutes processing times.
In foregoing real silk fabric low temperature pre-treating method, the water temperature of the step 5. is 35 DEG C.Compared with prior art,
The present invention carries out the pretreatment compared with low temperature using alkali lye to real silk fabric, eliminates the silk gum and wax of the shallow-layer on real silk fabric surface
Matter, in order to which biology enzyme penetrates into hole, then carry out deep layer degumming using acid protease so that the degumming of real silk fabric entirety is more
Add complete.The treatment temperature of the present invention is controlled below 80 DEG C, is not in that boiling is boiled, liquid relative flow is relatively low, knits
Do not allow the spray for being also easy to produce greater impact power to wipe between thing, therefore can effectively protect real silk fabric surface smoothness and smoothness, make
It must dye more uniformly, be less prone to aberration, simultaneously because the intrapore colloid of real silk fabric is also fully removed, during dyeing
Dyestuff penetration rate is high, does not allow fugitive color not only, and can improve the color saturation of fabric.
