List of this article: 1, the function of silk 2, what is the function of silk? 3. The efficacy and function of silk. What are the characteristics and functions of silk? The efficacy of silk 1 The specific amino acid content of silk sanitary napkins can be automatically oxidized and decomposed.
2. Silk sanitary napkins can absorb and release ultraviolet rays, and have anti-inflammatory and bactericidal effects.
3. Silk sanitary napkins can effectively inhibit the production of melanin in the skin and have the effect of whitening the skin.
4. Silk peptides in silk sanitary napkins can prevent female infertility.
Knowledge of silk sanitary napkins
1. First of all, the attachment layer of silk sanitary napkins is silk, which is very clean and does not need bleaching in the remanufacturing process, which helps us solve the biggest threat.
Silk is very breathable. For example, we buy some silk clothes in summer because they are fresh and breathable.
3. Silk protein contains 18 kinds of amino acids beneficial to human body. Many products on the market begin to pay attention to the amino acid of silk fetus, because its benefits to human body are immeasurable.
4. Silk tires can whiten. This product will make the skin of women's private parts gradually white and delicate. In the process of use, the most obvious point is comfort, O allergy, breathability and no reverse osmosis.
Silkworm is called the second skin of human beings. Don't think that allergy is a trivial matter, and the capillaries burst as soon as they expand and contract.
Therefore, when the physiological period has passed, the reproductive system is not smooth due to allergies, resulting in insufficient blood. At this time, the age of girls grows particularly fast. Every menstrual period is uncomfortable and allergic, which will lead to ovarian problems for a long time. The key to the beauty and health of women's skin lies in the quality of ovaries.
6. What does allergy bring to girls? During the physiological period, you will feel uncomfortable, painful and red, indicating allergies. Sanitary napkins must be reused.
7. There was a customer who came to buy sanitary napkins. He said that he knew that those sanitary napkins in the world could not be used, but there was no way. Can you have your period? So you can only use them.
It's good to finally have a safe and secure product now. It's really not easy for us girls to hear this, and we are very grateful to have such a product on the market with zero allergy, which is deeply loved by women and well received.
8. And all our products are tested with zero fluorescent agent and zero allergy. No big-name sanitary towel on the market can make natural silk, which is unique. We have two patents for invention and two patents for use.
What is the function of silk? Silk can be used to make quilts, clothes, medical care, industry, skin care and other places.
Silkworm, called mulberry quilt for short, is made of mulberry silk. Silkworm silk is white with yellow color, and it feels delicate and smooth. The quilt made of silk is soft and snug.
The bulkiness, warmth retention and air permeability of silk quilt are better than those of tussah silk quilt. The service life of a bed of mulberry silk quilt is about 10 to 15 years, while tussah silk quilt can only be used for two to three years.
The efficacy and function of silk Silk is a natural fiber, which is a continuous long fiber solidified by silk liquid secreted by adult silkworms when they cocoon.
One of the earliest animal fibers used by humans.
Let me introduce the efficacy and function of silk to you, hoping to help you.
The efficacy and function of silk
1. Silk fibroin and sericin are components of spun silk in the medical field. After being treated with concentrated sulfuric acid, the same substance as heparin can be obtained, which has anticoagulant activity and delays blood coagulation time, and can be used to develop blood testing equipment or antithrombotic materials.
By changing some processing conditions in the same way, spun silk rich in water absorption and water retention can be processed into advanced water-based materials or other physiological health care products.
In addition, the spun silk is chemically synthesized by polymer, so that calcium or phosphorus can be condensed with the spun silk, and an "orthopedic material" for orthopedic treatment can be developed.
Similarly, after chemical treatment, artificial muscles or artificial ligaments can also be developed.
Silk fibroin films made of spun silk can also be made into wound protection films for treating burns or other skin injuries.
2. The silk powder processed into particles in the industrial field can be used as an additive for cosmetics or health food, and can also be made into silk paper containing silk powder or food fresh-keeping packaging materials and antibacterial silk materials.
Silk fibroin film is not only used to process contact lenses, but also can be used to mix silk powder as fine as 0.3μm with resin to develop a new product called silk leather.
High-grade coatings made by adding silk powder into some coatings can be used to spray furniture supplies, increase the elegant appearance and good touch of utensils, and are widely used in various indoor decorations.
3. Natural silk fabric mask, leading the new beauty trend.
The structure of natural silk is very similar to human skin, so it has the reputation of "second skin" of human body.
Silk beauty has a long history in China. As early as the Ming Dynasty in China, silk was used by court ladies for daily beauty and health preservation because of its important medicinal value.
According to Compendium of Materia Medica, silk protein powder can eliminate skin dark spots and treat suppurative dermatitis.
Modern medical experiments further prove that the protein content of silk is much higher than that of pearl, in which the nitrogen content is 37 times that of pearl, and the main amino acid content is as high as 10 times.
These amino acids can be directly absorbed and adsorbed by human hair and skin.
That is, it is easier to penetrate into the outer layer of human epidermis and accelerate the metabolism of skin.
Chemical constituents of silk
The chemical composition of silkworm cocoons raised by mulberry leaves is: moisture 1.40%, ash 1. 14%, protein 97.34%, ether soluble extract 0.26% and fiber 0.39%.
Cocoons are mainly made of fibrous protein FIROIN wrapped with another sericin from protein, and also contain a small amount of oil, pigment and inorganic substances.
In raw silk, silk fibroin accounts for about 70% and sericin accounts for about 22%.
Silk fibroin is a kind of keratin, and its amino acids are glycine and alanine, which account for about 80% of the total nitrogen.
105g fibroin contains amino acids in the following order (the number after the substance is the number of moles): glycine 578, alanine 38 1, valine 29, leucine 7, isoleucine 9, serine 157, threonine 12, tyrosine 67, phenylalanine 8 and proline.
Sericin is also keratin, and its amino acids are generally similar to silk fibroin, but glycine, alanine and tyrosine are slightly different. Serine, glutamic acid and aspartic acid are more.
Cocoon also contains 50mg% free hydroxy acid (calculated by glycine).
Cocoon contains oily waxy substances, which are composed of primary alcohols (C28-C32), solid fatty acids (C26-C32), paraffin wax (C25-C3 1) and liquid fatty acids.
It also contains sitosterol (glucoside) and lupeol.
Identification method of silk
Check the appearance
High-quality silk is milky white, slightly yellow, with soft surface luster, no blackening, no astringency and long silk quality. After the surface silk is pulled open, there is no flocculent broken silk inside.
Combustion discrimination
After burning, it smells of burnt feathers, because it contains protein, which turns into powder with the color of wildfire after burning. When burning, it gives off the smell of burnt hair, and there is no fire.
color reaction
Concentrated nitric acid turns yellow
touch control
High-quality silk feels soft, greasy, elastic and free of lumps, while inferior silk feels rough, inflexible and wet.
fibre strength
The better the strength and elongation of silk, the better the quality. After stretching, the longer the silk quilt, the better the quality.
Selection method of silk
First of all, the so-called silk usually refers to the mulberry quilt, which is a domestic silkworm egg with mulberry leaves as its staple food. The silk spit out by silkworms is yellowish white, delicate and smooth, and the quilt made of this silk is soft and close to the skin.
The bulkiness, warmth retention and air permeability of mulberry silk quilt are better than those of tussah silk quilt, and its service life is longer than that of tussah silk quilt. The service life of a bed of mulberry silk quilt is about 10 to 15 years, while tussah silk quilt can only be used for two to three years.
When choosing, you usually follow seven steps.
At first glance, many manufacturers' silk quilts are marked with 100% silk, which is problematic because both mulberry silk quilts and tussah silk quilts can be called silk quilts.
Second inspection: high-quality silk should be milky white, slightly yellow, with soft surface luster, no blackening, no astringency and no flocculent broken silk inside.
Three-pull: pull a small amount of silk from the sample seal. If it is easy to pull, it is probably fake.
Four burns: burn with a lighter to see if there is burnt feather smell.
Five kneading: first knead the silk at the sample mouth by hand, and then knead other places. If it feels different, it proves that other ingredients have been added.
Six-pressure: press hard after folding the wire to see if the rebound is slow.
Seven smells: mulberry silk quilt has a faint fragrance.
Advantages of silk
Silk is the lightest, softest and finest natural fiber in nature. After the external force is removed, it can be easily restored to its original state. The inner tube is not caked, tight, uniform and soft, and can be used permanently without turning over.
Silk is made of fine silk and has a novel fiber structure, so that water vapor can circulate freely.
Coupled with the unique air permeability and moisture permeability of silk itself, silk is more slippery, cool but not warm, warm but not dry.
Mulberry silk is mainly composed of animal protein, which is rich in 18 amino acids necessary for human body. It can promote the vitality of skin cells, prevent vascular sclerosis, prevent skin aging after long-term use, have special antipruritic effect on some skin diseases, and have certain health care effects on arthritis, scapulohumeral periarthritis and asthma.
Known as "the second skin of human body" and "the queen of fiber".
There are various carotene derivatives in yellow cocoon, which are also cocoon colors such as yellow orange, pink and brown gray.
Washing and maintenance of silk
1 Silk should be washed with neutral detergent. After washing, it can't be twisted or exposed to the sun, and it can be hung naturally to dry.
When washing mulberry silk, if you can add a spoonful of vinegar to the water, the washed fabric will be more colorful.
3 air-dry to 80% dry and iron at medium temperature. It is best to remove wrinkles. When ironing, the reverse side is facing up, keep luster, avoid spraying water and avoid water stains.
What are the characteristics and functions of silk? Silk is made up of many tiny fiber molecules, which are aligned like bundles of chopsticks and regularly arranged in parallel along the long axis.
Its main organic matter is fibroin.
This protein is very tough, so it is difficult to break it.
The light on the surface of silk is reflected, refracted, transmitted or interfered, showing a soft luster like ivory and pearl, which is called "pearlescent".
Silk is the longest fiber among natural fibers.
The silk fiber of silkworm cocoon is composed of silk continuously vomited by old silkworm babies.
When reeling, a cocoon the size of a jujube can extract monofilament fibers as long as 1- 1.5 km, and the longest can reach 3 km.
It's hard to imagine that this soft and slender wire in your hand is actually a rigid material, and its tension is almost the same as that of steel wire.
First, the role of silk in the medical field
Nowadays, many medical products and instruments are made of high-quality silk.
After special treatment, it will have the effect of promoting blood circulation and anticoagulation, and can also help the blood to delay coagulation.
In addition, silk materials are also used in different medical tools, such as artificial ligaments, bone bonding materials, artificial tendons, various physiological health products and so on.
Second, the role of silk in the industrial field
In different industrial projects, silk powder can be added to coatings and mixed to make high-quality coatings.
These coatings can help furniture keep brighter colors and more elegant textures.
Therefore, the role of silk in industry cannot be ignored.
Third, silk beauty products lead the whole beauty industry.
In the past two years, experts in the field of beauty have found that natural silk is highly similar to human skin.
So silk beauty products began to emerge one after another.
According to relevant historical records, silk protein powder can not only help our skin to eliminate dark spots, but also contain a lot of protein needed by human skin, even higher than ordinary pearl powder and so on.
Nowadays, the sales of silk skin care products such as silk protein mask and silk cream on the market are very high.
And according to the related experimental results, the silk mask is easier to penetrate into the surface layer of human skin than the general mask, thus helping the skin to metabolize faster.
Thus, in the beauty industry, the role of silk is more extensive and important.
Nowadays, all kinds of silk skin care products are also sought after and loved by people of different ages.
Fourthly, in the field of home textile products, the role of silk.
Nowadays, silk products can be seen in many home textile stores, bedding stores and online platforms.
Why should silk be added to such products? We should know that natural fibers like silk, exposed for a long time, can not only make people's skin have a more delicate and smooth texture, but also further inhibit the breeding of bacterial mites.
In addition, if you are allergic, choose silk home textile products to ensure that the probability of your allergy is greatly reduced.
Nowadays, natural products like silk are used in different fields, because it has countless influences on human body.
I believe that in the future, silk will involve more fields.
Silk is a natural fiber in nature, which is very soft and delicate.
To this end, it has played the most critical role in different fields.
With more and more places, materials like silk are widely used.
It also caused problems such as the role of silk, which caused the collection of different groups.
You know, silk can not only make clothes, home textile products, health care products, etc., but also show its charm in cosmetics and other industries.
