Problems solved by technology

It can be seen from the above prior art that the pigment content in silk fibroin can be increased by means of high-temperature dipping / steaming, but the effect is general and not very satisfactory. Natural colored silk is processed by steaming combined with grafting and curing processes, and the pigment content in silk fibroin Pigment content is significantly increased, but the process is more complicated, which is not conducive to industrial production

Embodiment 1

[0017] (1) Swelling: remove impurities from the natural colored silk, let it sit in warm water at 35°C for 20 minutes, and take it out after swelling occurs on the surface of the natural colored silk.

[0018] (2) Pigment adsorption and transfer: immerse the swollen natural colored silk in a nano-color fixing agent with a mass fraction of 2% nano-scale pigment adsorbent and 1.5% cross-linking agent EH, vibrate at 45°C for 30 minutes, and take it out. Wash with deionized water and steam at 80°C for 30 minutes.

[0019] (3) Degumming and pigment fixation: After degumming at 90°C to remove excess sericin on the surface of natural colored silk, immerse in the pigment fixative solution, soak at a constant temperature of 75°C for color fixation, wash once at 25°C, and dry at 60°C When the water content of natural silk is 25%, natural colored silk with color retention is obtained.

Embodiment 2

[0021] (1) Swelling: remove impurities from the natural colored silk, and soak it in warm water at 40°C for 10 minutes until the surface of the natural colored silk swells, then take it out.

[0022] (2) Pigment adsorption and transfer: immerse the swollen natural colored silk in a nano-color fixing agent with a mass fraction of 2% nano-scale pigment adsorbent and 1.5% cross-linking agent EH, shake at 45°C for 60 minutes at low temperature, and take it out. Wash with deionized water and steam at 100°C for 20 minutes.

[0023] (3) Degumming and pigment fixation: After degumming at 80°C to remove excess sericin on the surface of natural colored silk, immerse in the pigment fixative solution, soak at a constant temperature of 65°C for color fixation, wash twice at 25°C, and dry at 60°C When the water content of natural silk is 25%, natural colored silk with color retention is obtained.

Embodiment 3

[0025] (1) Swelling: Remove impurities from the natural colored silk, let it sit in warm water at 40°C for 20 minutes, and take it out after the surface of the natural colored silk swells.

[0026] (2) Pigment adsorption and transfer: immerse the swollen natural colored silk in a nano-color fixing agent with a mass fraction of 2% nano-scale pigment adsorbent and 1.5% cross-linking agent EH, shake at 45°C for 60 minutes at low temperature, and take it out. Wash with deionized water and steam at 100°C for 30 minutes.

[0027] (3) Degumming and pigment fixation: After degumming at 90°C to remove excess sericin on the surface of natural colored silk, immerse in the pigment fixative solution, soak at a constant temperature of 75°C for color fixation, wash once at 25°C, and dry at 60°C When the water content of natural silk is 25%, natural colored silk with color retention is obtained.

Abstract

The invention discloses a color retention processing method of novel colorful silk. The method comprises the following steps: soaking natural colorful silk in warm water at first, then transferring the natural colorful silk into a nanometer fixing agent, degumming after steaming treatment, and finally carrying out fixation treatment to obtain color retaining natural colorful silk. The method comprises the following steps: combining the nanometer fixing agent with pigment at first, then fixing the pigment inside and on the surface of fibroins through the steaming treatment, then removing redundant sericin, and finally firmly fixing the pigment in the fibroins to achieve the purpose of color retention. The color depth and the K / S value of the natural colorful silk prepared by the method are obviously improved, and the color retention rate is high and is nearly close to the chroma of the original natural colorful silk.

Description

Technical field: [0001] The invention belongs to the technical field of silk products, in particular to a color-preserving processing method of natural colored silk. Background technique: [0002] "Fiber Queen" silk has always been loved by the public. The natural colored silk in silk is a new variety in silk, which is mainly divided into yellow-red cocoon and green cocoon. Natural colored silk has rich colors unmatched by natural colored cotton, and also has good anti-ultraviolet, anti-oxidation and antibacterial properties. Among them, the structural properties of yellow silk fibers are less different from those of white silk, because the porosity between silk protein molecules in silk is larger, so the flexibility, warmth retention, air permeability and moisture absorption and release performance are better than white silk. silk. [0003] At present, due to the change of people's concept of green ecological consumption, the market of natural colored silk is very tight, ...
