In modern medical research, it has been found that silkworm cocoons have a good effect of dispelling wind and antispasmodic, and also have a good effect on some stroke diseases.

2. Silkworm cocoons can dissolve phlegm and disperse knots.

In some patients with phlegm nucleus and lymphitis, silkworm cocoon can be combined with other phlegm-reducing drugs, which can make sputum nucleus patients have a good effect, which is a valuable experience in many clinical diseases. The effect of silkworm cocoon is also a good relief effect for some patients with chronic pharyngitis.

3. Silkworm cocoon has a good effect of clearing heat and detoxifying.

Among the effects of silkworm cocoons, the effect of clearing heat and detoxifying is very good, since ancient times, there are many medical Kwai Bao medical books, there are records that the detoxification effect of silkworm cocoons is very good, especially for children and other types of fever, there is a good heat dissipation effect.

Quality inspection

1. The value of silk quantity.

It mainly refers to the silk yield and the silk yield of fresh cocoons.

2. Relief value.

Including the relaxation rate, the length of the silk and other traits related to the production efficiency of silk reeling.

3. Silk value.

Including cocoon silk denier, thickness gap and cocoon silk traits.

4. Group value.

It refers to the uniformity of various shapes between the cocoon grains of the same batch of silkworm cocoons and the number of cocoons in the batch.

These four values together constitute the commodity value of the cocoon, a raw material for the silk reeling industry. All cocoons with high cocoon rate and good relief, long silk and high silk production rate are excellent cocoons. In addition, the white color of the cocoon, the normal luster, the cocoon shape and other characteristics are also important criteria for high-quality cocoons.

The above-mentioned standards can generally be determined by the dry shell inspection method and the silk reeling inspection method.

Draw silk, make silk, and raise silkworm chrysalis.

Use mulberry leaves or wheat stalks to make a "hill" look, and they will spin silk on the "mountain" and form cocoons.

When the silkworm baby reaches the end of the fifth instar, it gradually shows the characteristics of old maturity: first, the excreted feces change from hard to soft, from dark green to leaf green; loss of appetite and decreased amount of mulberry eaten; The anterior digestive canal is empty, and the thorax is hyaline; Then the food is completely stopped, the body drive is shortened, the abdomen also tends to be transparent, the cephalothorax of the silkworm body is raised, the mouth is spitting, and the left and right swing up and down to find a place to camp in the cocoon. Put the ripe silkworm in a special container or on a crow, and the silkworm will spin silk and form a cocoon.

Cocoon formation can be divided into four processes: 1. The mature silkworm first spits out the silk and binds it to the cocoon, and then spins the silk to connect the surrounding cocoon branches to form a cocoon bracket, that is, a cocoon net. The cocoon net does not have a cocoon shape, but is just some soft and messy cocoon silk layer to serve as a support for the cocoon.

2. After the silkworm knots make the cocoon net, continue to spit out the messy silk circle, thicken the inner layer of the cocoon net, and then spin the silk in an S-shaped way, and the outline of the cocoon begins to appear, which is called the cocoon coat. The silk fibers of the cocoon are fine and brittle, arranged very irregularly, and have a lot of sericin content. 3. After the cocoon is formed, the cocoon cavity gradually becomes smaller, the front and rear ends of the silkworm body are bent to the back to form a "C" shape, the silkworm continues to spit out the cocoon silk, and the silking method changes from the S shape to form, which begins the process of forming a cocoon layer.

4. When the silkworm has a large amount of silkworm spinning and its body is greatly reduced, the cephalothorax swing speed slows down, and there is no certain rhythm, and the silkworm begins to appear messy, forming a loose and soft cocoon silk layer, which is called a pupal lining.

<>1. Silkworm cocoons can be made into various textile products after processing, and silk quilts can be made into silk quilts.

2. It can be spun into various clothing, such as silk pajamas, silk underwear (bra), silk T-shirts, etc.

3. It can be made into various styles of silk scarves.

4. It can be made into a children's silk cotton jacket, which is warm and breathable, which is very suitable for babies and children.

5. It can be made into beautiful handicrafts.

<>1. The quantity is large, and it can be sold to the cocoon station.

2. The number is small, make your own silk quilt, of course, this requires some technology.

3. Otherwise, make your own pillow, the silk pillow is soft, comfortable, breathable, and healthy.

4. As for how to make silk pillows, this is not difficult, boil the silkworm cocoon, pull the silk by hand, sort it into a twist, then add some edible alkali, boil it in boiling water for dozens of minutes again, and boil the sericin clean - you can't cut corners, otherwise, if you have sericin, you will not sleep long and it will be flattened because of sericin bonding. Dry, loosen and put in a pillowcase.

Characteristics of silkworms before cocooning:

After another 7-8 days after 4 molts, the silkworm will become quiet and no longer eat mulberry leaves. When the body begins to turn yellow and shiny, and the stool is much larger than usual, the head keeps swinging, and the muscles of the head pants expand and contract back and forth with the swing.

At this time, it is necessary to put something that can be supported in the silkworm box to help the silkworm make a cocoon and give the silkworm a suitable environment to form a cocoon.

You can use a cardboard box to make a checkered cluster, and the silkworm will climb into it to form a cocoon on its own.

It takes about two days and two nights to complete a silk cocoon, so there is no need to be nervous, just quiet and not disturb them.

The process of silkworm cocooning:

1. Make a stent.

The silkworm first spits out the silk, then glues it to the chopper, and then spins the silk to connect the surrounding supports, gradually forming a cocoon net. The cocoon net does not have a cocoon shape, but is just a layer of soft and messy cocoon silk to form a cocoon as a support for the cocoon.

2. Outlines appear.

After making cocoon clothes, continue to spit out messy silk circles, thicken the inner layer of cocoon nets, bend the silk way, spin silk to make cocoon clothes, and begin to appear cocoon-shaped outlines, the silk of cocoon clothes is slender and brittle, the arrangement is irregular, and the sericin content is also more.

3. Start spinning.

The silkworm will spit out the silk into a neat "8" shaped silk circle, and each weave more than 20 silk circles (called a silk column) will move the body to move the body, and then continue to spin the silk and weave the silk column below, and then weave the other end after weaving one end.

4. End of spinning.

Finally, when the silkworm has a large amount of silkworm spinning and its body is greatly reduced, the chalothoracic swing speed will slow down, resulting in the loss of rhythm, and the silkworm will begin to appear messy, forming a loose and soft cocoon silk layer, which is called a pupal lining.

The cocoon after breaking the cocoon is no longer useful. When the silkworm bites the cocoon, the silk of the cocoon is broken, and the silk cannot be drawn at all, so generally no one will want to break the cocoon, because the silk cannot be extracted.

Silkworm cocoon usually refers to mulberry silkworm cocoon. The sac-shaped preservation of the silkworm at the pupal stage carries a sheath and contains a pupal body. The protective layer includes the cocoon coat, the cocoon layer and the pupal lining. The cocoon layer can be reeled, and the cocoon clothes and the reeled waste silk can be used as raw materials for silk cotton and silk spinning.

The cocoon is oblong, oval girdle, spherical or spindle-shaped and other different shapes, or slightly constricted in the middle, the cocoon has white, yellow, light green, flesh red and other colors, about 3 4 cm long, diameter cm, white surface, irregular wrinkles, and attached silk, fluffy. The silk pattern on its inner wall is very regular. Lightweight and tough, not easy to tear.

The cocoon is not feathered, with 1 yellow-brown silkworm pupae and a light brown and shrunken silkworm skin that is taken off before the pupation is made.

Silkworm cocoons are formed by bonding the fibers that are spit out after molting the larvae of the silkworm. Silkworm cocoons are one of the precious materials used as household goods and in the manufacture of silk textiles. Silkworm cocoons are the key to thousands of homes and products.

The structure of silk production is made up of the undulating fibers of the cocoons used to spin silk. This special structure gives silk a strong toughness.

2.Main uses of silkworm cocoons:

Silkworm cocoons have a wide range of uses, from limb to silk, but can also be used to make other fabrics, printing and dyeing, and artistic creations. In many cultures, silkworm cocoons are also one of the main foods in the diet. In some Asian communities, cocoons are soaked in water and eaten, and this method of eating is also prized for its high protein content.

In addition to the laughter of this experience, some of the ingredients in silkworm cocoons can also be used in the production of drugs and cosmetics.

3.The economic value of silkworm cocoons:

Since the cocoon is the main material of silk and food, it has significant economic value. In silk production, silkworm cocoons are placed on a silk machine, where they are rinsed and processed to become beautiful silk fabrics. Due to the beauty and high quality of silk, the contribution of silkworm cocoons to the silk industry cannot be underestimated.

In addition, the extraction and processing of silkworm cocoons has become an important employment opportunity, and many families and businesses rely on it for their livelihoods.

4.Application of silkworm cocoon in the field of science and technology:

With the rapid development of science and technology, many new applications of silkworm cocoons have been discovered. For example, based on the fibrous properties of silkworm cocoons, scientific lead families have explored the possibility of using them in medical materials, such as repairing broken blood vessels and tissues. In addition, the fibers of silkworm cocoons can also be used to make high-tech materials, such as bulletproof materials, because the fibers of silkworm cocoons have very good toughness and toughness.

The peptide antimicrobial components contained in silkworm cocoons are also widely used in the medical field.

5.The impact of silkworm cocoons on the environment:

While silkworm cocoons have many values, they also have certain negative effects on the environment as their manufacture often involves many handling and chemical processes. The chemicals used in the extraction and processing of silkworm cocoons in many businesses can lead to the production and discharge of toxic waste by-products, which can further harm water and air quality. Fortunately, some businesses and policymakers are taking action to ensure that the processing of silkworm cocoons does not affect the environment or public health.

6.Conclusion:

Silkworm cocoons are known for their unique fibrous texture and their many uses in cultural, commercial, and technological fields. While cocoons have played an important role and become the cornerstone of many impressive achievements, we must be aware of its impact on the environment and look for more environmentally friendly processing methods to ensure the sustainability of silk production.
