Most people know that silk is comfortable, and silk is more comfortable than tussah silk, mainly because the silkworm itself is smaller, finer and silky than tussah. So do you know how the silk was made? Cocoon selection: after the silkworm cocoons, the silkworm farmers will send the cocoons to the silkworm station or directly purchased by the silk reeling factory or the silk quilt factory, and the workers will classify the cocoons, such as the upper cocoon, the double palace cocoon, the macular cocoon, the rotten cocoon, etc. The silk was graded from here!

Cocoon drying: drying the cocoon (that is killing pupa) to remove the moisture in the silk and prevent the silkworm from turning into a butterfly, destroying the integrity of the cocoon and avoiding the oil content of the silk exceeding the standard.

Cocoon stripping: begin to peel the cocoon and remove the cocoon because the cocoon is thin and fragile, and the silk strands can not be used for beating cotton; and this cocoon is also a staple of silk and belongs to a low grade silk quilt.

Wiping: the silk fiber is adsorbed on the drum by rotating the drum according to a certain proportion, the silk is separated from other staple fibers such as silkworm pupae, and the long silk wool is used to produce high quality mulberry silk quilts.

Primary washing: the silk wool removed from the beating machine generally contains impurities such as pupa skin. Remove these impurities through coarse washing to ensure that silk is free of impurities.

Boiled cotton: the main purpose of the boiled cotton is to separate other impurities such as sericin, pupa oil and silk fiber from the silk, so as to reduce the oil content of the silk, make the silk soft, and prolong the service life.

Fine washing: separate sericin, pupa oil after the silk wash clean, so that softener PH regulator can better permeate silk, make silk softer.  

Ph regulation: silk is slightly alkaline, in order to reach the acceptable range of human body, need to use acid to neutralize PH; if silk has sour taste, it may be the reason that the glacial acetic acid in this place is too much.

 

Cotton selection: the process of producing silk wool will contain some tendons. If the wattle is not clean, black lines will appear in the light, a small amount is normal, the amount of silk quality is not very good.
