What is the function of silk? Silk can be used in quilts, clothes, medical, industrial, skin care and other places.
Silk refers to mulberry silk quilt, which uses mulberry silk. The silk spun out by mulberry silkworms is white with yellow color, and feels delicate and smooth. The quilt made of silk is soft and close to the body.
The fluffiness, warmth and air permeability of silk quilts are better than those of tussah silk quilts. The service life of a mulberry silk quilt is about 10 to 15 years, while the tussah silk quilt can only be used for two to Three years.
Efficacy and role of silk Silk is a continuous long fiber formed by solidifying the silk liquid secreted by mature silkworms when they spin cocoons. It is also called natural silk and is a natural fiber.
One of the earliest animal fibers utilized by humans.
Now I will introduce to you the efficacy and function of silk. I hope it can help you.
Efficacy and role of silk
1. In the medical field, silk fibroin and sericin, which are components of silk, can be treated with concentrated sulfuric acid to obtain the same substance as heparin, which has Anti-coagulant activity and the ability to delay blood coagulation time can lead to the development of blood test equipment or anti-thrombotic materials.
Using the same method to change some processing conditions, the silk with rich water absorption and water retention properties can be processed into high-grade water-based materials or other physiological health care products.
In addition, the silk can be processed through polymer chemical synthesis to condense calcium or phosphorus with the silk, and "bone-synthesis materials" for orthopedic treatment can be developed.
Artificial muscles or artificial ligaments can also be developed after chemical treatment.
Silk fibroin film made of silk as raw material can also be made into a wound protective film to treat burns or other skin injuries.
2. Silk powder processed into microparticles in the industrial field, in addition to being used as additives in cosmetics or health foods, can also be made into silk paper containing silk powder or packaging materials for food preservation and has antibacterial properties. silk material.
In addition to being used to process contact lens lenses, silk fibroin film can also be mixed with silk powder as fine as 0.3μm and resin to develop a new product called ¨silk leather".
A high-grade paint made by mixing silk powder into certain paints and used to spray furniture, which can increase the elegant appearance and good touch of the utensils. It is widely used in various interior decorations.
3. Natural silk fabric mask, leading a new trend in beauty
The structure of natural silk is very similar to human skin, so it is also known as the human body's "second skin"
Silk. Beauty has a long history in China. As early as the Ming Dynasty in my country, silk was used by imperial concubines for daily beauty and health care because of its important medicinal value.
According to the "Compendium of Materia Medica": silk protein powder. It can eliminate skin dark spots and treat purulent dermatitis.
Modern medical experiments further prove that the protein content of silk is much higher than that of pearls, the nitrogen content is 37 times higher than that of pearls, and the main amino acid content is more than 10 times higher. .
These amino acids can be directly absorbed and absorbed by human hair and skin
That is, they can penetrate more easily into the outer layer of human epidermis and accelerate skin metabolism.
Chemical composition of silkworm silk
The chemical composition of the cocoon of silkworms reared with Rumulan leaves is as follows: moisture 1.40, ash 1.14, protein 97.34, ether-soluble extract 0.26, fiber 0.39.
Silkworm cocoons are mainly made of the fibrous protein Fibroin, which is bonded with another protein Sericin, and also contain a small amount of oils, pigments, inorganic substances, etc.
p>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 composed of glycine and alanine. At most, the nitrogen of these two amino acids accounts for about 80% of the total nitrogen.
The amino acids contained in 105g of silk fibroin are as follows (the number after the substance is the number of moles): glycine 578, alanine 381. Valine 29, Leucine 7, Isoleucine 9, Serine 157, Threonine 12, Tyrosine 67, Phenylalanine 8, Proline 5, Tryptophan 2, Lysine 4, Histidine 2, arginine 6, aspartic acid 17, glutamic acid 13, totaling 1297 moles
Sericin is also a keratin, and its amino acid composition is roughly the same. Similar to silk fibroin, the slight difference is that there are less glycine, alanine, and tyrosine; more serine, glutamic acid, and aspartic acid.
Cocoon also contains 50 mg of free hydrogen acids. (Calculated as glycine).
Cocoons contain oily waxy substances, composed of primary alcohols (C28-C32), solid fatty acids (C26-C32), paraffin (C25-C31) and liquid fatty acids. /p>
It also contains sitosterase (glucoside) and lupulin (Lupeol)
How to identify silk
Check the appearance
High-quality silk is milky white and slightly yellow. The surface of the silk has a soft luster. It is not black, not astringent, and the silk quality is long. After the surface silk is pulled apart, there is no flocculated broken silk inside.
Burning identification
After ignited, it has the smell of burnt feathers because it contains protein. After burning, it becomes a wildfire-colored powder. When burned, it emits the smell of burnt feathers without any fire.
Color reaction
It turns yellow when concentrated nitric acid is added
Touch
High-quality silk feels soft, smooth, elastic and has no lumps , inferior silk feels rough to the touch, has no flexibility and no moisturizing feeling.
Fiber strength
The better the stretchability of silk, the better the quality. After stretching, the longer the silk thread of the same length, the better the quality.
How to select silk
First of all, what is usually called silk refers to mulberry silk quilt, which uses mulberry silk. Mulberry silkworms are domesticated species that feed on mulberry leaves as their staple food. The silk produced by mulberry silkworms is white with yellow in color and feels delicate and smooth. The quilts made from this silk are soft and close to the body.
The fluffiness, warmth and breathability of mulberry silk quilts are better than those of tussah silk quilts, and their service life is longer than that of tussah silk quilts. The service life of a mulberry silk quilt is about 10 to 15 years. The tussah silk quilt can only be used for two to three years.
When selecting, generally follow 7 steps.
A quick look: There are many manufacturers on the market whose silks are labeled as 100 silk. This 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 and slightly yellow, with a soft luster on the surface, no blackness, no astringency, and no clumps of flocculent broken silk inside.
Three pulls: Pull out a small amount of silk from the sealing port. If it is easy to pull, it is probably fake.
Fourth burning: Use a lighter to burn to see if there is a burnt feather smell.
Five kneading: first knead the silk at the mouth of the sample with your hands, and then knead other parts. If the feel is different, it proves that other ingredients have been added.
Six pressures: After folding the silk, press it hard 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. It can easily return to its original shape after external force is removed. The inner tube does not cake, become stuffy or shrink. It is even and soft, and can be used permanently without turning.
The silk quilt is made of the finest silk and has a novel fiber structure that allows water vapor to circulate freely.
Coupled with the unique breathability and moisture permeability properties of silk itself, the silk quilt feels smoother, cool but not warm, warm but not dry.
Mulberry silk is mainly composed of animal protein and is rich in 18 kinds of amino acids necessary for the human body. It can promote the vitality of skin cells and prevent vascular sclerosis. Long-term use can prevent skin aging and has special effects on certain skin diseases. It has anti-itching effect and has certain health care effects on arthritis, frozen shoulder and asthma.
It is known as the "second skin of the human body" and the "Queen of Fiber".
The pigments contained in yellow cocoons include various carotene derivatives, and they are also the pigments of yellow-orange, pink, brown and gray cocoons.
Silk washing and maintenance
1. Mulberry silk should be washed with neutral detergent when washing. After washing, it should not be twisted or exposed to the sun. It should be hung to dry naturally.
2 When washing mulberry silk, if you add a small spoonful of vinegar to the water, the fabric will be brighter and brighter after washing.
3 Let it dry until it is 80% dry and then iron it at medium temperature for the best wrinkle removal. When ironing, the wrong side is facing up to maintain the luster. Avoid spraying water to avoid water stains.
What are the characteristics and functions of silk? Silk is composed of many fine fiber molecules oriented like bunches of chopsticks and regularly arranged parallel to the long axis.
Its main organic matter is fibroin.
This protein is very tough, so it takes a lot of effort to break it.
The light on the surface of silk, some reflected, some refracted, some passed through, or interfered with, showing a soft luster like ivory and pearls, which people call "pearl light" .
Bombshell silk is the longest fiber among natural fibers.
The silk fiber of a silkworm cocoon is composed of silk continuously spun out by a mature silkworm baby.
When reeling, a silkworm cocoon the size of a red date can pull out monofilament fibers that are 1 to 1.5 kilometers long, and the longest can be 3 kilometers long.
It is hard to imagine that this kind of soft and slender silk is actually a stiff material, and its pulling force is almost the same as that of steel wire.
1. The role of silk in the medical field
Many medical products and appliances are now 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 grafting materials, artificial tendons, various physiological health products, etc.
2. The role of silk in the industrial field
In different industrial projects, silk powder can be added to paint to produce high-quality paint.
These coatings can help furniture items maintain brighter colors and more elegant textures.
For this reason, the role of silk in industry cannot be ignored.
3. Silk, the best beauty product, leads the entire beauty industry
In the past two years, experts in the beauty industry have discovered that natural silk material is highly similar to human skin.
For this reason, silk beauty products have begun to emerge in endlessly.
According to relevant historical records, silk protein powder can not only help our skin eliminate dark spots, but also contains a large amount of protein required by human skin, even higher than ordinary pearl powder.
Nowadays, the sales of various silk skin care products such as silk protein masks and silk creams are very high on the market.
And according to relevant experimental results, silk masks are easier to penetrate into the surface of human skin than ordinary masks, thereby helping the skin metabolize faster.
In this way, the role of silk in the beauty industry will become more extensive and important.
Nowadays, various types of silk skin care products are also sought after and loved by people of different age groups.
4. The role of silk in the field of home textile products
Now we can see silk materials in many home textile product stores, bedding stores and online platforms. product.
Why does such a product also contain silk? You must know that long-term contact with natural fibers like silk can not only make human skin more delicate and smooth, but can also further inhibit the growth of bacteria and mites.
In addition, if you are allergic, choosing silk home textile products will ensure that your chances of allergies are greatly reduced.
Nowadays, natural products like silk are used in different fields because it has countless effects on the human body.
I believe that in the future, the fields involved in silk will be more extensive.
Silk is a natural fiber found in nature, very soft and delicate.
For this reason, it plays the most critical role in different fields.
As more and more places begin to use materials like silk extensively.
As a result, issues such as the role of silk have aroused the collection of different groups.
You must know that silk can not only be used to make clothing, home textile products, health care products, etc., but can also show its charm in industries such as cosmetics.
