How to make silk after silkworm cocooning, how to turn silkworm cocoon into silk

Recently, many guests have expressed great interest in the handmade methods from silkworm cocoons to silk cotton while buying silk quilts and silk products

First of all, it is necessary to choose a high-quality double-palace silkworm cocoon, (that is, there are two silkworm pupae in it).

1. Burning: (the foundation is the most important).

Boiling cocoons, boiling cocoons is very particular, first of all, the time must be mastered, cooking is too bad, in rural terms, it is not firm to make quilts in the future, too raw will affect processing, and there will be raw blocks on the finished product. In addition, the ingredients added should be quantified. In order to pursue the whiteness of silk, some manufacturers add excessive whitening agents, and I have not studied whether this will affect the fiber of silk, but the silk used in the countryside will not add whitening agents.

2. Dialing: After the cocoon is cooked, it is manual work.

Dial the cocoons one by one in your hand and remove the chrysalis and their black peeling. In the process of removing there will always be a little bit of silk sticking, which can be used by the machine to make silk cotton sheets, can also be processed into quilts, this ** is low, and we will remove some times (such as thin cocoons) when we choose double palace cocoons, these thin cocoons can also be used by machines to beat machine silk cotton sheets.

The specific method of dialing: the high-quality double palace cocoon can be pulled into a small piece as long as you dial about 5 in the hand. This process is best carried out in clean, running water.

3. Open: This is the semi-finished product of making silk quilts.

Open these small pieces on the fixed mold shape (pay attention to pulling evenly), generally use 5 small pieces on it, and then use a dehydrator to dry, pay attention to be very dry, otherwise the silk will not be so soft. Dried! It must be very dry!

This is a semi-finished product that is pulled into a quilt, and some customers often compare it to "the kind that wants to look like a hat" haha, extremely smart!

4. Pull (the last key).

In the past two years, the method of pulling by 4 people has been adopted, and the "hat" is pulled into the size of the whole quilt, the first few are pulled by two people, and a quilt should be fitted together piece by piece, and now some of them still turn it over like this at home. Pay attention to uniformity when pulling, which requires an experienced master.

Silkworm cocoons first emerge silkworm chrysalis, and then scald with boiling water and then draw silk.

1. Cocooning: Then dry the cocoon (kill pupae), and at the same time remove the moisture in the silk, so that the silk is not easy to turn yellow.

2. Stripping cocoons and beating cotton: the silk fibers are adsorbed on the drum by rotating the drum in a certain proportion, and the silk is separated from other staple fibers such as silkworm pupa. Remove the cocoon clothes of the silkworm cocoons (the cocoon clothes are thin and fragile, and the silk strands are disorganized, so they cannot be used for cottoning).

3. Initial washing: The silk cotton removed from the cotton beater generally contains impurities such as pupae skin, and these impurities are removed through rough washing.

4. Boiled cotton: The main purpose of boiled cotton is to separate other impurities such as sericin, pupal oil and silk fibers in silk cotton.

5. Fine washing pH adjustment: wash the silk cotton after separating sesame and pupal oil, so that the softener and PH adjuster can better enter the silk cotton. Silk cotton is alkaline, and in order to achieve the acceptable range of the human body, pH neutralization is required.

6. Cotton selection (manual rib strips): In the process of producing silk cotton, there will be some ribs, which should be removed. If the vitex is not clean, it will appear under the condition of light, if a small amount is normal, and the amount is large, it means that the quality of silk is not very good.

7. Baking cotton: The silk cotton produced can kill the germs in the silk cotton under high temperature baking. The moisture content is controlled within a controllable range.

8. Wire drawing: using the traditional hand-drawn Wang Zhi process, the semi-finished silk is loosened and stretched, and the silk is paved layer by layer, criss-crossed, and compressed layer by layer.

1. Choose a cocoon.

When making handmade silk quilts, you should choose spring silkworm double palace cocoons, because the mulberry leaves in spring are tender, and the silk made should be smoother. Shuanggong cocoon refers to a cocoon with two or more silkworm pupae in the cocoon, which cannot be reeled, but it is the best product for making silk quilts.

2. Boil cocoons. Boiled in a special container, it is a degreasing process, and finally most of the sericin on the surface is peeled off, and the weight of the silk is halved. After degreasing, the silk quilt is not easy to compact, and it can be turned over.

Put the dried cocoons in warm water and cook for about 20 minutes, at this time you can put a little baking soda, the purpose is to make the tightly structured cocoons loose, so that the next step is to reel. Everyone may be worried about whether baking soda is safe in the quilt, but it is actually very safe, and everyone notices that when steaming steamed buns in restaurants, baking soda will be put in order to make the steamed buns fluffy. Steamed buns can be eaten, and of course the quilt can be covered with confidence.

How to cook silkworm cocoons to be threaded:

If you want to draw silk, boil it in water for a few minutes, if you want to draw it into a piece of silk cotton (the method of making silk quilt), you need to add some soda or baking soda, and cook it for ten minutes to half an hour (the amount of alkali is different, the cooking time is different, the more alkali, the shorter the cooking time). You can take one and pull it halfway through. Cocoon silk length and cocoon silk weight refer to the length and weight of cocoon silk that can be reeled from a cocoon.

Generally, the spring cocoon silk is 900 to 1500 meters long, and the cocoon silk weighs grams; Summer and autumn cocoon silk 700 1200 meters long, cocoon silk weighs grams. The length and rate of the silk reflect the difficulty of the cocoon silk dissociation from the cocoon layer during silk reeling. The length of the silk is the average length (m) of the cocoon silk that can be continuously reeled once per joint in the process of silk reeling.

The relaxation rate is the percentage of the length of the cocoon silk to the length of the cocoon. If the relief is good, there will be less thread, more silk, ***; The solution is poor, the amount of waste silk increases, the yield rate and the quality of raw silk decrease, and the reeling of silk often consumes a lot of energy and costs due to the re-threading.

The filament rate refers to the percentage of the filament weight in the cocoon weight, or expressed by the reeling rate of the cocoon layer, which is a comprehensive indicator of the quality of the cocoon. The filament rate is mainly determined by the cocoon rate, cocoon layer rate and relaxation rate. The silking rate of fresh cocoons is generally 14% 16%, and the high can reach 19% 21%.

The silk reeling rate of the cocoon layer is the percentage of the silk weight to the weight of the cocoon layer, which is generally 75% to 85%. The cocoon filament titer indicates the degree of cocoon filament thickness. The unit is denier, abbreviated as "denier" or "d", commonly known as "fen" or "strip", that is, the 900-meter-long cocoon line weighs 1 denier.

For machine silk reeling, manual silk drawing of silkworm cocoons requires certain techniques and procedures.

You can first put the cocoon into the water, boil the water, and then use tweezers and other tools to constantly stir the cocoon, the cocoon will become looser and looser with the rolling of the water, and then the silk head will come out. Find the thread, wrap it around the loop, and pull it out like a wire.

Silkworm cocoon drying and storage The process and management process of using heat energy to kill silkworm pupae in fresh cocoons and dry cocoons while maintaining cocoon quality and preventing mildew. Silkworm cocoons are dry, commonly known as baking cocoons. In addition to killing silkworm pupae in time, preventing feathering and cocoon layer steaming heat and mildew, the main thing is to remove most of the water in the fresh cocoon, especially to dry the pupa.

Nowadays, it is generally reeled by machine. If you want to draw silkworm cocoons by hand, you need to have certain techniques and procedures. First put the cocoon into the water, boil the water, and then use tweezers and other tools to constantly stir the cocoon, the cocoon will become looser and looser as the water rolls, and then the silk head will come out.

Find the thread, wrap it around the loop, and pull it out like a wire.

Note: After the cocoon is finished, it must be drawn in time, otherwise the silk will be broken.

To smoke the silk of the cocoon, you can soak the cocoon in boiling water, and after a while, the silk head of the cocoon will appear in the water, pick up the silk head with your hand or object, wrap it around the wooden stick or other similar things, you can continue to wind, until the silk of the entire cocoon is pumped out, and only the silkworm pupae are left in the water.

(1) It is to boil the cocoon, that is, to use hot water to expand the cocoon, this process is not too long, that is, to expand the sericin of the cocoon, and then facilitate the silk.

2) It takes time to draw silk, and according to the different tools of the workshop, the length of time is uncertain, but it will take several hours to make a cocoon of a silk quilt.

3) It is the degumming of silk, and the process of degumming, washing and dehydration takes several hours.

4) After degumming, the cooked silk should be dried, and then the good dryer.

5) It is hand-drawn, whether it is a large factory or a small workshop, without exception it is hand-pulled, this is fast, and it can be completed in ten minutes.

You need a professional for this, right?

China is an early country in raising silkworms and reeling silk - understand the production of silk - from silkworm raising to spinning silk cocoons - silk reeling, and then to the beautiful silk fabrics and practical silk non-woven fabrics.

In the history of the development of textile raw materials in China, whether it is kudzu or cotton, it is a unique textile crop, although the regional ways are different, but after a long period of cultural exchanges, in the end, it is still to learn from each other's strengths, and the same way. But silk is very different, he is an indelible contribution to world civilization in ancient China, and it is the real quintessence of the country! Silk is famous for its excellent quality, exquisite colors and rich cultural connotations, from the Yellow Emperor to the next few thousand years, only the Chinese civilization silkworm raising, silk reeling technology, weaving the world of silk.

The silk threads spit out by the silkworm babies have stretched out the thousand-year-old Silk Road; The dreamlike beauty of silk not only glorified the land of China, but also shocked the entire Western civilization; From Alexandria to Caesar, from Rome to Constantinople, they were all fascinated by the beauty, tenderness, and luster of silk.

Formation of silk:

Mulberry silk, the silk extracted from the cocoon of the mulberry silkworm knot, is composed of two triangular or semi-elliptical silk fibroin and sericin two globulins, with an oval cross-section. Silk fibroin accounts for about 3 4 and sericin accounts for about 1 4. Its color is white with yellow, and the feel is delicate and smooth.

From mulberry to silkworm cocoon, what are the steps through which silkworm cocoons can be turned into silk?

1. Peel off the cocoon. There is a layer of cocoon clothing on the outside of the cocoon, the fibers are thin and fragile, and the strands are disorganized and must be peeled off first. In order to facilitate the selection of cocoon operation and the identification of cocoon quality. At the same time, it is necessary to ensure the accuracy of the cocoon cooking, which is carried out on the cocoon peeling machine.

2. Choose a cocoon. According to the requirements of the silk making process, it is generally necessary to remove the secondary cocoon, the lower cocoon and the double palace cocoon, and select the high-quality upper cocoon as the raw material for silk reeling.

3. Boil cocoons. The screened silkworm cocoons are boiled, and the sericin around the cocoon silk is properly moistened and dissolved by using the action of water and heat, so that the glue force between the cocoon silk is weakened, which is conducive to silk reeling and other processes.

Then the follow-up processing of silk reeling or cotton making into silk, which can be used in silk clothing, home textiles, health and beauty care and other fields.
