Problems solved by technology

[0011] At present, the biggest problems existing in the processing of silk floss sheets and silk floss quilt manufacturing enterprises are: first, the environmental pollution problem during the processing of machine-made silk floss sheets; second, the poor elasticity of silk floss; use
But the most serious problem is that a large amount of sericin in the scouring liquid after scouring with this degumming agent cannot be recovered at all.

Embodiment 1

[0036] Preparation of strong alkaline electrolyzed water: add ordinary tap water to the electrolytic cell, or add a small amount of electrolysis accelerator such as sodium chloride to the ordinary tap water, turn on the power to make the electrolytic cell work, collect the alkaline electrolyzed water at the cathode outlet, adjust the size of the current or The flow rate of tap water was used to obtain electrolyzed water with a pH of about 11.50. After filtering or standing overnight, the filtrate or supernatant was used for all experiments in the present invention, and it was generally sealed and stored in a refrigerator at 4°C for future use.

[0037] Put the shaved cocoon, silk fiber or waste silk directly into the strong alkaline electrolyzed water prepared by the Sheng, boil and degumming for 10-60 minutes to obtain sericin solution and silk fibroin from which sericin has been removed.

Embodiment 2

[0039] Put tap water in the electrolytic cell, prepare a series of strong alkaline electrolyzed water with pH of 10.0, 10.5, 11.0, 11.5, 12.0, and conduct boiling degumming test with common silkworm cocoon shell (bath ratio 1:40, W / V ). Divided into the above 5 groups according to the difference of pH value, each group was repeated three times, each group weighed about 2.0 g of clean ordinary cocoon shells, and recorded the weight of the cocoon shells. Put the weighed cocoon shells into the triangular flask respectively, add electrolyzed water with different pH values ​​according to the bath ratio of 1:40, and boil. Stir constantly during the boiling process to make the heating even. After boiling for 20 min, the silk was taken out and rinsed with double distilled water, wrung out and dried in an oven at 80°C. After 2 h, it was taken out and weighed to calculate the degumming rate. The formula for calculating the degumming rate was:

[0040] Degumming rate = (weight of cocoon...

Embodiment 3

[0043] Electrolyzed water with a pH of about 11.50 was prepared according to Example 1. Weigh clean common cocoon shells, divide them into 5 groups, do three repetitions for each group, weigh about 2.0 g of clean common cocoon shells for each group, and record the weight of the cocoon shells. Put the weighed cocoon shells into the triangular flask, and add electrolyzed water with a pH of 11.50 according to the bath ratio of 1:40 (W / V). Boiling degumming, stirring constantly during the boiling process, so that the heating is even. After 5, 10, 20, 40, and 60 min, take out the silk and rinse it with double-distilled water, wring it out, and put it in an oven at 80°C for drying treatment. After 2 hours, take out the silk and weigh it to calculate the degumming rate, as shown in Figure 2 It is the experimental result graph of the effect of strong alkaline electrolytic water degumming time on silk degumming. Boiling degumming in strong alkaline electrolytic water with a pH of 11.5...

Abstract

The invention discloses a silk degumming/scouring agent and applications thereof, and concretely discloses a silk degumming/scouring agent strongly-alkaline electrolytic water, and new uses and new technologies of the silk degumming/scouring agent in processing processes comprising silk wadding quilt processing, cut bave or silk degumming, silk cotton, pure silk blank material refining and the like. Common tap water directly is directly electrolyzed through a water electrolyzing device or an electrolytic tank to form strongly-alkaline electrolytic water having a pH value of 11.0-12.0, and the strongly-alkaline electrolytic water can be used as a silk wadding sheet scouring agent, a cocoon shell or silk degumming agent, a silk cotton scouring agent, a pure silk or blank silk scouring agent, and the like. The silk degumming/scouring agent has the advantages of small damage to silk fibers, complete degumming, maintenance of the original resilience and other mechanical performances of the fibers, realization of direct low-cost high-efficiency recovery of sericin from a degum solution without desalination, and avoiding of the server environmental pollution of sericin-containing alkaline wastewater and the huge biological resource waste.

Description

technical field [0001] The invention relates to a cocoon degumming agent or silk scouring agent, which can be used as a cocoon shell or silk degumming agent, silk cotton sheet, silk spinning and silk blank scouring agent, etc., and realizes green, low-cost and high-efficiency recovery of sericin protein purpose. Background technique [0002] Silk is a natural protein fiber produced by silkworms. The sericulture and silk industry has always been a traditional advantageous industry in my country. In the world, with the longest history and traditional silk culture, "planting mulberry and raising silkworms, making silk and weaving silk" has always been a true portrayal of the working people in our country. [0003] Silk fiber is mainly composed of 65-75% silk fibroin, 20-30% sericin and about 5% wax, pigment, sugar and impurities. Silk fibroin is a kind of crystalline fibrous protein, and it is covered with a colloidal sericin protein, which plays the role of gluing silk fibro...
