First of all, you should choose the best double-clan silkworm cocoon (that is, there are two cocoons inside) Burning - dialing - opening - pulling: 1, burning: (basic is the most important) Cooking boiled, boiled oysters are very particular, first of all, time must be mastered, boiled too bad, in rural terms, it is not good to do quilts in the future, too, it will affect the processing, there will be raw blocks on the finished product. The ingredients added are also quantified. In order to pursue the whiteness of silk, some manufacturers add excessive whitening agents. Whether this stuff will affect the fiber of silk, I have not studied it, but the silk used in rural areas will not add whitening agent. . 2, dial: silkworm cocoons are cooked by hand Place the silkworm cocoons one by one in the hands, remove the silkworm cocoons and their black peelings (some black spots on the quilts are not cleaned), there will always be a little bit of silk sticking during the removal process. This silk can be used to make silk cotton pieces with a machine, or it can be processed into a quilt. The price is low. Also, when we choose Shuanggong, we will remove some times (such as thin enamel), which can also use machine to make silk cotton. The specific method of dialing: the superior double palace can be pulled into a small piece by dialing about 5 in the hand. This process is best done in clean flowing water. 3, open Open these small pieces on a fixed mold (pay attention to pull evenly), generally use 5 small pieces, and then use a dehydrator to dry, be sure to take off very dry, otherwise the silk will not be so soft. Dry! Be sure to be very dry! This is the semi-finished product of the quilt. When a Wenzhou businessman came to us to wholesale semi-finished products, he asked us "to be like a hat". Haha, smart! 4, pull (the last key) In the past two years, the method of pulling four people has been adopted. The "hat" has been drawn into the size of the whole quilt. The former ones are pulled by two people, and one quilt has to be pieced together. Now some of them have turned over their homes. When you pull, pay attention to uniformity. This requires an experienced master. Well, the silk inner tube is formed, and the outer cotton skim sleeve is placed on the outside, which is dense, or a cotton high-density wide-width cotton cloth cover. (Many manufacturers of inner tubes will use some of the narrower fabrics, which are lower in price) 1. Silk is also called silk cotton. The white silk that comes out of the silk factory is made of textiles, not made of quilts. 2, silk has been used for a long time, there is always no new so fluffy, but always very soft, very close to the body, to renovate can add a new silk on both sides.
