Problems solved by technology

If the silk required for washing the silk quilt contains sericin, the silk will bond during washing, making the silk quilt agglomerated and affecting the use of the silk quilt
If the content of sericin is high, it is difficult to avoid moisture or sweat during use, so it will harden after a long time, which will affect the user experience
Therefore, in the process of processing the silk used as silk, the sericin wrapped outside the silk fibroin is generally degummed, and the sericin is degummed clean, but the degumming of the sericin will make the luster and feel of the silk affected. influences

Embodiment 1

[0024] A kind of coagulated silk degumming process involved in the present embodiment comprises the following steps:

[0025] (1) Cocoon removal: Use silkworm cocoon removal machine combined with manual selection to remove impurities.

[0026] (2) Beating: the silkworm cocoons after impurity removal are beaten with a beater to obtain silk floss sheets; and the sericin content is measured for each batch of silk floss sheets. The sericin content of the silk floss sheet was detected to be 25.2%.

[0027] (3) Degumming: Put the silk floss sheet into the degumming treatment solution containing hydrogen peroxide, mercerized soap and sodium naphthalene at a bath ratio of 1:10, and stir for 2.5 hours at 80°C. In the degumming treatment liquid, the mass percentage of hydrogen peroxide is 5%, the mass percentage of mercerized soap is 1%, the mass percentage of natron is 1%, and the balance is water.

[0028] (4) Glue fixing: Put the silk floss sheet degummed in the previous step in th...

Embodiment 2

[0031] A kind of coagulated silk degumming process involved in the present embodiment comprises the following steps:

[0032] (1) Cocoon removal: Use silkworm cocoon removal machine combined with manual selection to remove impurities.

[0033] (2) Beating: the silkworm cocoons after impurity removal are beaten with a beater to obtain silk floss sheets; and the sericin content is measured for each batch of silk floss sheets. The sericin content of the silk floss sheet was detected to be 23.7%.

[0034] (3) Degumming: Put the silk floss sheet into the degumming treatment solution containing hydrogen peroxide, mercerized soap and sodium naphthalene at a bath ratio of 1:12, and stir for 2 hours at 90°C. In the degumming treatment liquid, the mass percentage of hydrogen peroxide is 5%, the mass percentage of mercerized soap is 1.5%, the mass percentage of natron is 2%, and the balance is water.

[0035] (4) Glue fixing: Put the degummed silk floss sheet in the previous step in th...

Embodiment 3

[0039] A kind of coagulated silk degumming process involved in the present embodiment comprises the following steps:

[0040] (1) Cocoon removal: Use silkworm cocoon removal machine combined with manual selection to remove impurities.

[0041] (2) Beating: the silkworm cocoons after impurity removal are beaten with a beater to obtain silk floss sheets; and the sericin content is measured for each batch of silk floss sheets. The content of sericin in the silk floss sheet is 29.2% after testing.

[0042] (3) Degumming: Put the silk floss sheet into the degumming treatment solution containing hydrogen peroxide, mercerized soap and sodium naphthalene at a bath ratio of 1:10, and stir for 2.5 hours at 90°C. In the degumming treatment liquid, the mass percentage of hydrogen peroxide is 10%, the mass percentage of mercerized soap is 1.5%, the mass percentage of natron is 2%, and the balance is water.

Abstract

The invention discloses a silk solidifying and degumming process. The silk solidifying and degumming process comprises the steps as follows: (1) impurity removal of silkworm cocoons: impurity removalis performed by use of a silkworm cocoon shaker in combination with artificial selection; (2) scutching: silk floss sheets are prepared from silkworm cocoons after impurity removal, and the content ofsericin is determined for each batch of silk floss sheets; (3) degumming: the silk floss sheets are placed in a degumming treatment solution containing hydrogen peroxide, textile soap and sodium silicate; (4) sericin fixation: the silk floss sheets are placed in a sericin treatment solution containing a sericin fixing refining agent, a softening agent and tartaric acid; (5) cleaning: the silk floss sheets are cleaned with clear water and centrifugal dewatering is performed. The silk solidifying and degumming process can degum most sericin, so that part of sericin exists on the outer side of fibroin in the silk floss sheets, has a certain antibacterial function and cannot harden due to long-term use. Besides, the silk floss sheets contain the sericin and thus have good gloss and have a skin nourishing effect after long-term use.

Description

technical field [0001] The invention relates to the technical field of silk processing, in particular to a coagulated silk degumming process. Background technique [0002] People in the silk industry know that the natural antibacterial, anti-mildew, and anti-moth functions of silk are mainly exerted by the characteristics of silk sericin itself. It will stink, the main reason is that mulberry silk gum has antibacterial and antibacterial effects. If all the sericin in silk products is washed out or destroyed, this function will be lost, and it will no longer be anti-bacterial, anti-mildew, and anti-insect. [0003] Silk used in silk quilts, especially silk used as washed silk quilts. If the silk required for washing the silk quilt contains sericin, the silk will bond together during washing, making the silk quilt agglomerated and affecting the use of the silk quilt. If the content of sericin is high, since it is difficult to avoid moisture or sweat during use, hardening wi...
