Embodiment 1

[0015] This embodiment adopts the method of immersion-steaming.

[0016] The natural colored silkworm silk fabric is immersed in the pigment transfer treatment solution containing 320g / L of urea, 0.2g / L of Pingpingjiao, and a bath ratio of 1:40 at 40°C for 30 minutes, then dehydrated, and then dehydrated at a temperature of Steam in a steam box at 100°C and 100% humidity for 60 minutes. After drying, carry out degumming treatment according to the conventional process, wherein Pingpingjia○ is the penetrating agent.

Embodiment 2

[0018] This embodiment adopts the method of immersion-dehydration-steaming.

[0019] The natural colored silkworm silk fabric is immersed in the pigment transfer treatment liquid containing thiourea 300g / L, Pingpingjia○ 0.1g / L, AE○ 0.1g / L bath ratio 1:40 at 60°C for 30 minutes, and then dehydrated , steamed in a steam box with a temperature of 102°C and a humidity of 95% for 60 minutes, and after drying, degumming treatment was carried out according to the conventional process, wherein Pingpingjia○ and AE○ are penetrants.

Embodiment 3

[0021] This embodiment adopts the method of high temperature impregnation.

[0022] Put the natural colored silkworm silk fabric into the pigment transfer treatment liquid of 350g / L of thiourea, AE○ 1g / L, bath ratio of 1:50, soak for 10 minutes at 50°C, heat up to boiling, keep warm for 2 hours, and dry Degumming is carried out according to the conventional process.

[0023] The natural color Bombyx mori silk fabric after the above-mentioned embodiment process process adopts following routine process to carry out degumming treatment: the alkaline solution (Na 2 CO 3 1.5g / L, Pingping plus ○ 1g / L, bath ratio is 1:50) in pretreatment for 20 minutes, then in 45 ℃ enzyme solution (2709 alkaline protease 1g / L, Pingping plus ○ 1g / L, bath ratio 1:50) for 30 minutes, washed with hot water at 70°C for 15 minutes, washed with cold water until neutral, and dried.

Abstract

The invention discloses a method for effectively increasing the pigment content in silk fibroin of silk from natural color silkworms. Wherein, urea and thiourea are used as pigment-transferring agent, and the fabric of silk from natural color silkworms is treated by hi-temp soaking or soaking-steaming so as to increase the content of natural pigment in silk fibroin of silk from the natural color silkworms. The content of natural pigment on the silk fibroin in fabric of silk from natural color silkworms treated by the invention is 2-3 times higher than that of non-treated fabric of silk from natural color silkworms with the same degumming rate after going through ordinary degumming process, this can not only maintain the color concentration of natural color silk, but also meet the requirement for silk fabric, and improves the actual use value and added value of natural color silk.

Description

technical field [0001] The invention relates to a method for increasing the color density of natural colored silk, which belongs to the technical field of textile processing. Background technique [0002] Natural colored silkworm silk is a new silk variety obtained by transferring the excellent colored cocoon genes of original species at home and abroad to high-yield and high-quality white cocoon varieties through gene recombination, and breeding high-yielding colored cocoon silkworm varieties, which are reeled. Natural colored silk avoids the harm of chemically synthesized dyes to the human body and the environment, making silk products more natural. [0003] The structure of natural colored silk is the same as that of ordinary silkworm silk, consisting of sericin and silk fibroin, and sericin is coated on the outside of silk fibroin. Sericin and silk fibroin have different proportions of amino acids and molecular structures. During the processing of silk fabrics, the diff...
