Abstract
The invention relates to a method for fixing pigment, in particular to a method for fixing pigment of colorful raw silk. The method for fixing pigment of colorful raw silk comprises the following steps: selecting raw silk reeled by a colorful cocoon; soaking the raw silk in pigment fixed liquid for 20-40 min; removing the fixed liquid; baking at a constant temperature of 105-115 DEG C for 2.5-3.5hours; and when the temperature is reduced to 65-75 DEG C, taking out of an oven. The technical scheme can lead the raw silk to have the characteristics of dirt and oil prevention and washing resistance when fixing the pigment and improve the comprehensive performance of the raw silk. The invention belongs to the technical field of application of natural high molecular materials.
Description
Technical field
The present invention relates to a kind of chromatopexis method, be specifically related to a kind of fixing pigment of colorful raw silk method.Belong to the natural macromolecular material applied technical field.
Background technology
Silkworm (Bombyx mori L.) by artificial domestication more than 5700 year, belongs to Lepidoptera Bombycidae complete metamorphosis in China, comprises four worm attitudes of ovum, larva, pupa and adult (moth) from generation to generation.Larva weaves silk to the later stage and cocoons, and people produce various silk fabricss to the raw material of mulberry cocoon as reel silk from cocoons system raw silk.
At present, the silkworm major part of raising in the production is white cocoon kind.The colored cocoon variety source of China is very abundant, and yellowish, golden yellow, yellowish pink, red, green etc. is arranged.In recent years, developed again, produced the method for coloured mulberry cocoon by freshening the food pigment.
But because the pigment of coloured mulberry cocoon mainly is distributed in the silk gum, with the clothes that colored silk is produced, because cyclic washing, the content of pigment makes the color of clothes bigger aberration occur also in continuous minimizing, influences the demand in market.
Active demand is fixed processing to the existing natural colorful cocoon resource and the pigment of the colored raw silk that adds the production of food pigment in the production, with the purpose that the pigment washing that realizes colored raw silk is not faded, expands the consumption market of colored raw silk.
Therefore, develop a kind of method of fixing the pigment of colored raw silk, can carry out deep processing, avoid washing the influence of decolouring, have the positive effect of reality the raw silk and the goods thereof of natural and artificial chromatic cocoon.
Summary of the invention
The purpose of this invention is to provide a kind of fixing pigment of colorful raw silk method, wash the purpose of not fading with the pigment of realizing colored raw silk.
To achieve the above object of the invention, the present invention is by the following technical solutions:
A kind of fixing pigment of colorful raw silk method may further comprise the steps:
1. choose the raw silk of chromatic cocoon reel silk from cocoons system, immersed chromatopexis liquid 20～40 minutes;
2. will from chromatopexis liquid, take out through step raw silk 1., slough fixer again;
3. will be through step raw silk 2., under 105～115 ℃ of constant temperatures, in baking oven, dry by the fire 2.5～3.5 hours after, close the power supply of baking oven;
4. wait for when described oven temperature drops to 65～75 ℃, will shift out described baking oven through step raw silk 3..
As preferably, above-mentioned steps is specially:
1. choose the raw silk of chromatic cocoon reel silk from cocoons system, immersed chromatopexis liquid 30 minutes;
2. will from chromatopexis liquid, take out through step raw silk 1., slough fixer again;
3. will be through step raw silk 2., under 105～115 ℃ of constant temperatures, baking was closed the power supply of baking oven after 3 hours in baking oven;
4. wait for when described oven temperature drops to 70 ℃, will shift out described baking oven through step raw silk 3..
As preferably, contain 1% nano water-proof auxiliary agent and 0.5% crosslinking agent EH in the described fixer.Nano water-proof auxiliary agent chemical composition is a fluothane acryl copolymer, and the crosslinking agent EH chemical composition is the acetate of epoxychloropropane and hexamethylene diamine condensation polymer.
As preferably, the method for sloughing fixer is to adopt Water Extraction Machinery to take off dried.
As preferably, temperature drops to the slowly cooling through 1 hour of 70 ℃ of needs.
Cooling should not be rapidly, and the shortcoming of rapid cooling is to be prone between the silk fiber to harden.
As preferably, the inventive method also has the conventional step of preserving behind cooling step, and described conventional condition of preserving step is room temperature, drying, shading, ventilation.
In order to guarantee the reliability of said method, the fixer preparation can be used 8 hours later continuously, needed important preparation fixer in 8 hours later on.Sample fixedly the time, should allow sample fully contact with fixer, and stir up and down in fixer.Sample should not be piled up blocked uply in drying course, also will stir up and down twice in the drying course.
Operation principle of the present invention is: utilize crosslinking agent to carry out waterproof auxiliary agent and silk gum crosslinked; make the skin of silk gum form hydrophobic diaphragm; thereby make the pigment in the colored raw silk silk gum in water, be difficult for losing, and realize the purpose that the pigment washing of colored raw silk is not faded.Simultaneously, the raw silk of handling through the inventive method also has antifouling, grease proofing, laundry-resistant characteristics.
Because the employing of technique scheme, compared with prior art, the present invention has following beneficial effect:
1, the technical program is simple to operate, and cost of investment is low;
2, the technical program can be fixed more than 95% of pigment in the colored raw silk;
3, do not contain any harmful material in the raw silk of employing the technical program fixed pigment;
4, the technical program can make raw silk have antifouling, grease proofing, laundry-resistant characteristics to the chromatopectic while, improves the combination property of raw silk.
The specific embodiment
This specific embodiment only is an explanation of the invention; it is not a limitation of the present invention; those skilled in the art can make an amendment present embodiment after reading this specification as required, but as long as all are subjected to the protection of Patent Law in claim scope of the present invention.
A kind of fixing pigment of colorful raw silk method comprises the steps:
(1) material and equipment: 1 kilogram in the raw silk of the yellow cocoon reel silk from cocoons system of natural colorful, constant temperature oven, 1 of 5 liters of glass container, ultraviolet specrophotometer, tweezers, Libra;
