Embodiment 0

[0031] Embodiment 0: (this example adopts traditional enzyme degumming method to process silk)

[0032] Weigh 2g of the long spit after the above step (1) and step (2) for enzyme degumming treatment, the specific operation is: soak it in 90°C hot water for 30min to make it fully swell, and then put it in 90°C Refining in alkaline solution at ℃ for 30min, the alkaline solution contains Na 2 CO 3 1.5g / L and Pingpingjiao 1g / L, the bath ratio of long spit and alkali solution is 1:50, after scouring is completed, put it in 45°C enzyme solution for scouring for 60min after cooling, the enzyme solution contains 1g of 2709 alkaline protease / L and Pingping plus O 1g / L, the bath ratio of long spit and enzyme solution is 1:50, after scouring, wash with hot water first, and then wash with cold water until neutral, then dry and weigh.

Embodiment 1

[0033] Embodiment 1: (this example has adopted the inventive method to process silk)

[0034] Soak 2g of long spit after the above step (1) and step (2) in 90°C water for 80 minutes, then place the long spit in a steamer for 30 minutes, the steaming temperature is 102°C, and the steaming humidity It was 98%, and degumming was carried out according to the enzyme degumming process of embodiment 0 after steaming.

Embodiment 2

[0035] Embodiment 2: (this example has adopted the inventive method to process silk)

[0036] Put 2g of the long spit treated in the above steps (1) and (2) in an aqueous solution of thiourea with a concentration of 5mol / L and immerse it at a temperature of 95°C for 70min, and then place the long spit in a steamer to steam After 60 minutes, the steaming temperature was 150° C., and the steaming humidity was 85%. After steaming, degumming was carried out according to the enzyme degumming process in Example 0.

Abstract

The invention discloses a processing method for keeping the colors of color silks. The method comprises the following steps of: (1) fully blending, peeling and selecting each batch of color cocoons to guarantee that reeled cocoon silks have a uniform color; (2) selecting the common collective control sample meeting control requirements; (3) soaking the cocoon silks accordant with the common collective control sample in hot water of which the temperature is 90 to 100 DEG C for 60 to 80 minutes, and steaming the cocoon silks in a steamer at the temperature of between 95 and 150 DEG C and the humidity of between 80 and 100 percent for 30 to 60 minutes; and (4) performing the traditional degumming treatment and subsequent traditional processes on the steamed cocoon silks. By the method, pigments can enter the interior of fibroin through steaming and does not fade after the silks are washed, so that color fixing effect is achieved.

Description

technical field [0001] The invention relates to the technical field of silk processing, in particular to a processing method for maintaining the color of silk. Background technique [0002] As we all know, the pigment of colored silk exists in sericin, and when dyed and degummed, the color of colored silk becomes white and loses the characteristics of colored silk. At the same time, due to differences in breeding conditions and methods, the colors of colored cocoons are different from each other. Even the color of the inner and outer layers of a cocoon is very different, from yellow to light yellow to light yellow to basically white, so in order to keep the color of raw silk consistent in the middle of the production process, it is particularly important to control the number of grains under the thread. If there are many new cocoons in Xuxia grains, the raw silk will appear yellow; on the contrary, if the thin-skinned cocoons have many threads, the raw silk will appear whit...
