Problems solved by technology

[0007] In the above-mentioned technical scheme, since the cyanuric chloride used is unstable in the air, is volatile, easily absorbs moisture, and can directly react with water to reduce its reactivity, the actual production has higher environmental requirements. Therefore, It is difficult to adapt to the requirements of printing and dyeing processing
And the shortcoming of the active dye fixing sericin of cyanuric chloride derivative is: when removing unfixed or fixing weak sericin, the reactive dye will fall off from the fiber due to hydrolysis, which not only wastes the dyestuff, but also increases the weight of the problem. Sewage treatment capacity
In a word, the processing methods of these weight-increasing real silk fibers all have certain shortcomings, especially the great impact on environmental pollution, and it is difficult to realize industrialized production at present.

Embodiment 1

[0018] See attached Figure 1 , the present embodiment adopts the processing method of weight-increasing real silk fiber, comprising the following steps: preparing raw silk skein or cheese material, fixing sericin treatment with a fixing agent containing rare earth metal ions, and then carrying out scouring, dyeing, finishing and oiling Processing, and then drying at a low temperature to obtain a weighted colored skein yarn or colored cheese yarn.

[0019] In the fixing sericin treatment step, first prepare sericin fixative solution, which is composed of sericin fixative and accelerator, wherein the rare earth metal salt is cerium sulfate and cerium nitrate, and the concentration of cerium ion is 0.04g / ml, the promotor is ammonium sulfate, and its concentration is 0.03g / ml, and the adjusted pH value is acidic about pH=4; the real silk fiber (raw silk) skein containing sericin is soaked at a temperature of 40°C in The above-mentioned sericin fixative solution is treated, and ...

Embodiment 2

[0022] as attached figure 2 As shown, the steps of the processing method for fixing sericin to increase the weight of real silk fibers are: preparing raw silk skein or cheese material, fixing sericin with a fixing agent containing rare earth metal ions, and directly woven or knitted fabrics after low-temperature drying. Weaving process followed by scouring, dyeing, finishing and oiling. The basic processing principle is the same, and it can also achieve the effect of weight gain.

[0023] Using the fixative solution treated by sericin fixation in Example 1, add 1 / 3 of the fixative solution according to the original formula, and soak in the above-mentioned sericin fixative solution at a temperature of 30°C for about 20 minutes. Finally, the sericin fixation treatment is completed, and the weaving process of woven or knitted fabrics is directly carried out after drying at a low temperature of 70°C.

[0024] The woven or knitted fabric is treated with a soda ash solution with ...

Abstract

A process for increasing the weight of pure silk fibre includes immersing the pure silk yarn in the sericin solution containing RE metal ions, alkali (or water) washing, removing the sericin not attached to the pure silk fibre by refining agent, dyeing and finishing.

Description

technical field [0001] The invention relates to a processing method for weight-increasing real silk fibers, in particular to a processing method for realizing weight-increasing real silk fibers by adopting fixing sericin. Background technique [0002] Silk fiber has bright luster, smooth and soft feel, good moisture absorption performance and light appearance, etc. It is a high-grade textile fabric and is known as the "fiber queen". Silk fiber is mainly composed of two proteins, silk fibroin and sericin, of which sericin accounts for about 25% of the total weight of silk fiber. Each silk is made of two monofilaments bonded by sericin in parallel. Each monofilament The middle is silk fibroin, and the outside is sericin. Sericin molecules are irregularly arranged in an amorphous structure, and the closer to the silk part, the more obvious its crystallinity, but the crystal part is much smaller than the silk part. Therefore, compared with sericin, si...
