Problems solved by technology

But this kind of conventional scouring degumming method, its whole process of degumming process all needs to be carried out in the aqueous solution of larger bath ratio, generally all needs to go through pretreatment, primary refining, re-scouring process, and technological process is long, needs to consume a large amount of chemicals ( Such as scouring agent, etc.), the time required for processing is long, the energy consumption is high, water resources are wasted, and a large amount of production wastewater is generated

Embodiment 1

[0018] See attached figure 2 , the technical process of silk fabric scouring and degumming in this embodiment is as follows figure 2 shown.

[0019] The fabric to be scoured and degummed is made of silk power spinning green body, unit weight: 90.64g / m 2 ;Dry the raw silk sample in an electric blast drying oven at a temperature of 110°C to constant weight, then put the sample into a low-temperature plasma processor preheated for 30 minutes, and use intermittent low-temperature plasma processing Method, the working atmosphere is argon, start to fill in argon with a vacuum of 5Pa, when the pressure reaches 80Pa, treat it with a discharge power of 60W for 5min; after taking it out, use a refining agent (formula: Na 2 CO 3 1.0g / L, Na 2 SiO 3 1.0g / L, sodium hydrosulfite 0.5g / L, dispersant 2.0g / L), according to the re-training process (bath ratio 1:50, temperature 98 ° C, time 40min) directly for re-training; then fully washed (95 ℃, 60 ℃ hot water and cold water fully washe...

Embodiment 2

[0035] Present embodiment is to the technological process of silk fabric refining degumming as figure 2 shown. The fabric used is silk twill, unit weight: 72g / m 2 ;Dry the raw silk sample in an electric blast drying oven with a temperature of 110°C to constant weight, then put the sample into a low-temperature plasma processor preheated for 30 minutes, adopt a continuous processing method, argon As the working gas of the low-temperature plasma, argon gas is filled with a background vacuum degree of 6Pa, and when the pressure reaches 20Pa, it is treated with a discharge power of 50W for 5 minutes; then, the retraining process formula and conditions of Example 1 are followed directly for retraining. Practice; then fully wash and dry.

[0036] Carry out dyeing processing to the fabric after the above-mentioned refining and degumming process, dyeing prescription:

[0037] Weak acid pink B4% (o.w.f), Yuanming powder 1 (g / l), Pingpingjia O 0.1 (g / l), bath ratio 1:100.

Abstract

This invention discloses one kind of silk textile fiber and its fabric fining come unglued method. Front it uses the low temperature plasma technology carries on to the raw silk textile fiber and its the fabric processes, substitutes the conventional fining come unglued center's pretreatment, initially practices working procedure, then the direct process duplicate practices, achieves to the silk textile fiber and its the fabric concise come unglued's goal. Because the low temperature plasma physical ability sericin the macro-molecule carries on to the raw silk textile fiber and its fabric surface shells and splatters sculpture, causes its stopped chain or sculpture dehiscence, loose, duplicate causes to practice the fining medicinal preparation to be able fast to seep, bulked, degrades (hydrolisis or enzymolysis) sericin, therefore, has the craft simply, the energy conservation is highly effective, is advantageous to the clean production and the environmental protection merit.

Description

technical field [0001] The invention relates to a method for degumming silk fiber and its fabric, in particular to a method for refining and degumming silk fiber and its fabric by using low-temperature plasma treatment technology. Background technique [0002] Silk fiber is mainly composed of fibrous silk fibroin and globular protein sericin. Among them, sericin is secreted by the middle silk gland of the silkworm body. When the silkworm spins the cocoon, the silk liquid located in the rear silk gland passes through the middle silk gland, and the sericin is attached to the surface of the silk fibroin to play a role Functions of lubricating, bonding and protecting silk fibroin. In the raw silk fiber, the content of sericin accounts for about 20-30%, and it is irregularly coated on the surface of silk fiber in the form of phosphorus-like particles. According to Komatsu Keichi's sericin theory (Textile Industry Press, "Silk Making Chemistry" 1990 second edition: P96-102), the...
