Abstract
The invention discloses a degumming and unwinding method for cocoons and relates to the technical field of a silk making production technology. The degumming and unwinding method for the cocoons comprises following steps: A, drying cocoons; B, soaking the cocoons; C, cooking the cocoons; D, reeling silk; E, performing cleaning; F, performing soaking; G, repeating the step E, and the degumming and unwinding method for the cocoons is finished. Compared with the prior art, the degumming and unwinding method can solve the problem that conventional cocoon degumming and unwinding are influenced by mass of the cocoons.
Description
Technical field
The present invention relates to fiber tow production technology field, especially a kind of unwinding method of coming unstuck promoting silk dissociation.
Background technology
In the production technology of throwing, need silk dissociation from silk cocoon, and remove the silk gum of silk outer layer covers, it is unwinding that this process is referred to as coming unstuck of silk cocoon; The unwinding method of existing degumming silkworm cocoons drops in cocoon cooking machine by silk cocoon, makes silk gum swelling and the dissolving of silk periphery, reduces the mutual deadlocked power of silk, and when making filature, silk can continuously dissociation successively; The reelability percentage that comes unstuck of silk cocoon is higher, and the quality of silk is better, also easier dissociation; The raw material silk cocoon that existing filature is produced, mostly from silkworm raiser's purchase, and due to the cultivating condition of silkworm raiser and the restriction of breeding technology level, size, the soft or hard of silk cocoon and have big difference containing damp rate, cause very large impact to the unwinding effect of coming unstuck of silk cocoon.
Summary of the invention
The object of this invention is to provide a kind of unwinding method of degumming silkworm cocoons, it can solve the unwinding problem being subject to the impact of silk cocoon sole mass of existing degumming silkworm cocoons.
In order to solve the problem, the technical solution used in the present invention is: a kind of unwinding method of degumming silkworm cocoons, comprises the following steps:
A, cocoon drying: will the silk cocoon of throwing be needed to put into drying room baking, baking time be 1 hour, and temperature is 90 DEG C ~ 100 DEG C;
B, immersion: the silk cocoon after baking is put into Na
2cO
3solution soaks 20 hours ~ 24 hours, Na
2cO
3the concentration of solution is 0.3% ~ 0.5%, and temperature is 10 DEG C ~ 15 DEG C;
C, cocoon cooking: pour the silk cocoon after soaking in cocoon cooking machine cocoon cooking;
D, filature: silk cocoon well-done in step C is put into reeling machine filature, obtains silk;
E, cleaning: the silk obtained in step D is put into 40 DEG C ~ 50 DEG C distilled water and clean;
F, immersion: silk is put into soak and soak 30 minutes ~ 40 minutes;
G, repetition step e, the unwinding method of this degumming silkworm cocoons completes.
In technique scheme, technical scheme can also be more specifically: described soak is mixed by the raw material of following weight portion: 0.05%NaOH:3 part ~ 6 part; 0.8%Na
2cO
3: 10 parts ~ 20 parts.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, carry out cocoon drying program at first, the moisture content in silk cocoon can be removed, reduce containing damp rate, and make the suitable sex change of silk gum, be beneficial to unwinding in silk reeling process of silk cocoon.
2, before cocoon cooking, first silk cocoon is soaked Na
2cO
3solution, makes silk gum swelling and the dissolving of silk cocoon periphery, reduces the mutual deadlocked power of silk, and when making filature, silk can continuously dissociation successively.
3, the silk obtained after filature carried out soaking and clean, the silk gum of silk outer layer covers is removed totally.
4, in the process that degumming silkworm cocoons is unwinding, use alkaline chemical solution, can reduce silk cocoon size and hardness to the impact of producing, the reelability percentage that makes to come unstuck is increased to more than 90%.
