How silk is made into cosmetics, silk production process

1. Dry the silkworm cocoon, and then put it in water to boil thoroughly, the time must be mastered, and it cannot be cooked too badly or too raw.

2. Put the boiled silkworm cocoon into a basin filled with water, then tear the silkworm cocoon with your hand to remove the silkworm chrysalis and its black peeling. <>

3. After tearing, the fixed mold should be evenly placed on the mold, and then dried with a dehydrator.

4. Dry the silk in a cool and ventilated place and dry it.

Pulling the silk out of the cocoon to keep it uniform in thickness is a very delicate labor. The silk extracted from a cocoon can be up to 800 to 1000 meters long, and it is thin at both ends and thick in the middle. When reeling silk, you need to soak the silkworm cocoon in warm water first, dissolve the sericin, and then stir constantly, scoop up the silk head, wrap the silk head around the silk winding tool, and continue to wind.

When the silk on the cocoon is more than halfway drawn, the new cocoon that has already been soaked is thrown in. Scoop up the new cocoon and close it to the half-smoked old silk. This is repeated batch by batch until it is reeled into a wire twist of uniform thickness.

Silk Unit Standard:

The silk embroidery cultural relics unearthed from the tomb of the Western Zhou Dynasty in Qishan, Shaanxi Province were determined that the silk used to weave silk at that time generally had three kinds of coarse, medium and fine, the coarse one was made of 21 cocoons, the middle one was drawn with the silk of 18 cocoons, and the fine one was drawn by the silk of 14 cocoons. For embroidery, it is thicker, and generally uses 50 cocoons to draw together. In ancient times, there was a strict unit standard for calculating the thickness of silk.

According to the "Collection of Famous Poems", it is recorded that the silkworm spits out suddenly, ten silkworms are silk, five silks are sorrowful, ten silks are liters, twenty silks are silk, forty silks are Ji, and eighty silks are total. "Hu" is the smallest unit of length calculation in ancient China.

Ten is a thread, ten is a millimeter. According to the conversion, the fineness of silk with a diameter of 1 is equivalent to special (denier).

Materials required: cocoon, water, alkali, nylon thread.

Tools required: pot, large basin, round bamboo bow.

The steps of making silk are as follows:

1. Choose a cocoon that has no problem.

2. Boil the cocoon, put it in a special container and boil, this is also a degreasing process, and finally most of the sericin on the surface falls off, and the weight of the silk is reduced by half.

3. After degreasing, the silk is not easy to be cemented, and it can be done without turning.

4. Peel off the cocoon, peel off the cocoon with your fingernails and take out the silkworm chrysalis, and stretch the silkworm cocoon on your hand, remove the silkworm chrysalis and its black peeling, stack it to 5 to 6 layers and take it off and gently pull it into a square silk piece, and the double palace cocoon such as the upper core ridge can be pulled into a small piece as long as you dial about 5 on the hand.

5. Open cotton, open is the meaning of stretching and pulling, and cotton is the meaning of silk cotton pocket.

6. Put the silk pieces on it on a bow-shaped bamboo tool, fold it to a thickness of 5 or 6 layers, and take it off to become a wet mulberry silk cotton bag.

7. Dry the cotton, remove the moisture from the wet silk cotton bag with a dehydrator, and then string it with nylon thread and take the model size to dry in the sun.

8. It must be taken off very dry, otherwise the silk will not be so soft.

9. Remove it after drying, and the silk is ready. <>

Silk is a symbol of ancient Chinese culture and the main material of ancient clothing in China. How is silk made?

The main raw material of silk is silk, that is, the silk spit out when the mulberry silkworm forms a cocoon, which is an animal protein fiber. Silkworms lay eggs on mulberry trees, i.e., silkworms; Silkworms hatch into ant silkworms, which are raised and matured by mulberry leaves. Mature silkworms begin to make cocoons.

But to turn the cocooned silk into woven silk, there are four more steps: mixing, peeling, selecting cocoons, boiling cocoons, and reeling silk.

Cocooning: According to the requirements of process design, people need to mix the cocoons produced in different regions in proportion. This expands the batch, equalizes the cocoon quality, and unifies the silk color.

When mixing cocoons, the cocoon color and cocoon shape are basically close, the uneven titer of the cocoon filament is small, and the length of the cocoon filament is generally not more than 200 meters.

Cocoon peeling: The cocoon fibers on the outer layer of the cocoon are thin and fragile, and cannot be used for silk reeling, so they must be peeled off first. For this reason, people also designed a special cocoon peeling machine to peel off the cocoon coat to ensure that the number of cocoons is accurate and cooked evenly in the subsequent silkworm cooking process.

The amount of cocoon clothing must be appropriate, because too much cocoon will affect the amount of silk, and the amount of spring cocoon cocoon clothing stripped accounts for about 2 of the total cocoon amount, and the autumn cocoon accounts for about about 2.

Cocoon selection: This process is to select cocoons according to the requirements of process design, and remove the lower foot cocoons that cannot be reeled in the raw material cocoon, so that the silk used to make silk is all high-quality silk. Cocoon selection is divided into two steps: rough selection and selection.

The rough selection is to select the double palace cocoon and the lower cocoon, and the rest are the upper cocoons that can be used for silk reeling; Selection is based on rough selection, the secondary cocoons are selected from the upper cocoon, and the cocoon shape is classified.

Boiling cocoon: Boiling cocoon can properly swell and dissolve sericin, enhance the toughness of cocoon silk, and ensure that cocoon silk can be continuously dissociated in order. Boiling cocoons is a key process in the process of silk making, and the quality of boiling cocoons can directly affect the quality of silk.

Silk reeling: Pulling out the silk from the cocoon is silk reeling. In the past, the silk was drawn by hand and then wound on the silk basket; Modern silk reeling generally uses machinery.

Silk reeling is one of the main processes in the silk making process. According to the requirements of the product specifications, a number of cooked cocoon silk is extracted and then combined to make raw silk or tussah silk.

1. The first is to boil the cocoon, that is, to expand the cocoon with hot water, this process is not too long, that is, to expand the sericin of the cocoon, and then facilitate the silk.

2. The second is to draw silk, which will take time, and according to the different tools of the workshop, the length of time is uncertain, because the silk is too fine, and the silk length of a silkworm cocoon can reach one thousand meters, you didn't think of it, right?

3. Then the degumming of silk should be boiled for a few hours with liquid soap and edible alkali!! Many small workshops cut corners to reduce this step, so that the silk obtained is raw silk, containing 25% of the weight of sericin, so it can be sold very low**. However, this kind of raw silk containing sericin or incomplete degumming not only feels hard, but also sweats and heats up for a long time, which will make the sericin bond.

High-quality silk still needs to be degummed and cooked silk. The process of degumming, washing, dehydration takes several hours.

4. After degumming, the cooked silk should be dried and tile.

Silk is spit out by silkworms == You raise silkworms to give it mulberry leaves, after a while it will spin silk to wrap itself into a cocoon, the cocoon is silk ==

The practice of ordinary farmers is to boil the cocoons in alkaline water, and after boiling and cooling, they begin to peel them by hand, remove the silkworm chrysalis inside, put the silk on a tool, and take down the silk on the tool and pull it after making a few more cocoons. After repeated repetition, it can be dried and used to pull the silk quilt.

.The silk spit by the silkworm can't be made into silk!

Cocoons made of silkworm silk are boiled in water and other materials, and then manually stripped to become silk. Or it can be turned into silk by the machine.

Silk is the fiber that mulberry silkworms spit out on mulberry trees. The larvae of the silkworm protect themselves in the cocoon before turning into a silkworm moth, from the cocoon to the silk.

Silkworm cocoons gather in hot and humid air, put the cocoons in hot water The cocoons will become soft or slowly become a slurry, and the dirty surface layer will fall off, and finally expose the end of the silk, each cocoon is a continuous 2000-4000 meters long silk.

A single cocoon can produce 1-3 km of silk.

Types of silk.

Silk can be made into many kinds of fabrics, twill and satin silk are different fabrics formed due to different silk weaving methods. It has a shiny front, and a dull back. Soft and smooth.
