Silk fabrics are a general term, which is not very formal, because silk fabrics can be divided into many categories according to different textile methods, such as satin, electrospinning, georgette, crepe de chine and so on. Silk fabrics are more general, because silk is not necessarily silk, and fabrics made of silk-like satin can also be silk. Therefore, when buying silk clothes, you must ask whether it is mulberry silk or silk, and pay attention to the ingredient label.
If you want to buy silk clothes, I know a Taobao shop called Silk Bird, which sells silk clothes. It's very cheap, only a dozen dollars. Just search for silk birds on Taobao. Honey, you can have a look.
What's the difference between silk and silk?
Silk is a kind of silk fabric, which is relatively thin. It is generally used to make pajamas or summer undershirts (high-grade silk fabric is also used to make cheongsam), but the fabric that is easy to wrinkle is relatively thick and is mostly used to make winter cotton-padded jackets or quilts (it is rarely used now).
What's the difference between silk and mulberry silk?
Silk, also known as "natural silk", is a kind of continuous long fiber which is solidified by silk liquid secreted by mature silkworms during cocoon formation. Like wool, it is one of the earliest animal fibers used by human beings. According to different foods, it can be divided into silkworm, tussah, cassava silkworm, camphor silkworm, willow silkworm and wild silkworm. Silk strips extracted from a single cocoon are called cocoon filaments, which are made of two single fibers bonded and wrapped by sericin. Silk strips extracted from several cocoons and wrapped with sericin can be divided into mulberry silk (also called raw silk) and tussah silk, collectively referred to as silk.
Mulberry silk is a natural animal protein fiber and the most important raw material for silk fabrics. Smooth, soft and shiny, warm in winter and cool in summer. There is a unique "silk sound" phenomenon when rubbing, with good ductility, good heat resistance and no resistance to salt water erosion. It is not suitable to be treated with chlorine bleach or detergent.
Silk is a kind of filament with mulberry silk as raw material and several cocoon filaments bonded together.

Identification and maintenance of real silk
Silk generally refers to silk, including mulberry silk, tussah silk, castor silk and cassava silk. Consumers can identify silk fabrics by the following methods.
1. Identification method of product number: domestic silks and satins are subject to the unified product number consisting of 5 digits * * * *, and the 1 from the left represents the material number of the fabric, the whole silk fabric (including mulberry silk and spun silk) is 1, the chemical fiber fabric is "2" and the blended fabric is "3".
Second, the price appraisal method: the price of real silk fabric is about twice that of chemical fiber and artificial silk satin.
3. Identification method of gloss and feel: evenly smear the sample and observe its appearance. Silk has light absorption performance, looks smooth and not like a mirror, has elegant and soft luster, is as bright as pearls, feels soft and elegant, has dense silk threads and wrinkles in hands, and the higher the purity and density, the better the feel of silk; Although the silk-like fabric has been softened and feels soft, the silk surface is dark and has no pearl luster. Chemical fiber fabrics are bright and dazzling, and feel stiff. In addition, silk products should have a slight grip. When two layers of fabric rub, it will produce "silk sound", but fabrics of other raw materials will not.
4. Burning method: part of the yarn is pulled out and burned, so that the silk can't see the naked flame and has the smell of burnt hair, and the silk turns into black particles, which can be crushed by hand; Silk will catch fire when it meets fire, and it smells like plastic. When the fire goes out, a hard rubber block will be left on the edge.
Silk has a high shrinkage rate, so you should choose a size larger than the actual demand when buying finished products. If it is cloth, it should be soaked in clear water for more than 5 hours before making, so that the cloth can completely absorb water, dry it, and then soak it for the second time, so that after soaking twice and drying twice, the silk will not be deformed and the clothes can be washed at will. But if you choose high-grade silk, you'd better dry-clean it, so the fabric doesn't have to be soaked in advance.
Maintenance method of silk clothing
Many people like to wear silk clothes. Silk clothing is breathable, cool, soft and elegant, which is the best choice for summer clothing.
1. When washing silk garments, use the washing liquid specially used for washing silk and wool fabrics (available in all supermarkets). Put the worn clothes in cold water. Please refer to the instruction manual for the amount of washing liquid. The amount of water should be enough to immerse the clothes. Soak for 5 to 10 minutes, and gently rub with your hands. Don't rub them hard. Rinse with cold water for three times after washing.
Second, dry in a cool and ventilated place with clothes facing outwards.
Third, when the clothes are 80% dry, spread a white cloth on the clothes and iron them with an iron (don't spray water). The temperature of the iron should not be too high to avoid yellowing. You can also flatten it by hand without ironing.
Fourth, silk clothes should be washed and changed frequently.
Five, wear silk clothing can not be rubbed on mats, boards and rough objects, so as not to pick up the silk.
6. Wash it when storing, and don't put mothballs.
Seven, silk and tussah silk clothing should be stored separately, so as not to make silk clothing yellow. White silk clothes should be wrapped in clean white paper when stored to avoid yellowing.
How to tell if it is real silk?
There are many methods to determine whether a piece of cloth or a piece of clothing is real silk, such as combustion identification, microscopic observation identification, dissolution identification, chemical coloring identification, melting point difference identification, infrared spectrum identification and so on. Then, consumers do not have the necessary testing conditions, how to identify the authenticity of silk? Here are two simple ways.
Steps/methods
1
Number:
Silk and satin have a unified product number, which consists of 5 digits. The first digit of the five digits from left to right is "1" for all silk fabrics, "2" for chemical fiber fabrics, "3" for blended fabrics, "4" for tussah silk fabrics and "5" for rayon fabrics.
2
Price:
The price of silk fabric is about 4 times higher than that of chemical fiber and silk satin.
three
Appearance:
Silk clothing has elegant and soft color, pearl luster and soft and elegant feel.
four
Features:
Silk products should have a slight grip, and when they rub against each other, they can hear a crisp sound, that is, "silk sound."
five
Combustion method:
When some yarns are drawn and burned, the silk can't see the naked flame, but has the smell of burning hair. The silk is gray into black particles, which can be crushed by hand.

Matters needing attention
There are many kinds of silk, including plain crepe satin (usually used as pajamas and our most common silk fabric), georgette, crepe de chine, Sambo satin, electrospinning, taffeta and so on. Each fabric has different gloss and uses. The "visual touch method" mentioned in the appeal is mainly aimed at clothes made of silk crepe satin plain fabric. "Burning method" is a common identification method for all silk clothes.
These five methods are generally applicable to all kinds of silk fabric products.
Silk is easy to wrinkle, and there is a saying that "no wrinkle is not silk". Wrinkling is not a quality problem.
What is silk fabric?
But generally speaking, silk is a colloquial word. If it is really expressed in words, it is generally written as 100% mulberry silk. Or 100% other fabrics. In addition, there is a special silk fabric, such as elastic silk fabric, elastic satin, elastic crepe, elastic georgette and so on. These fabrics are elastic, but the silk itself is not very elastic, so some elastic fabrics will definitely be added, and spandex is added here. Generally, elastic silk fabrics consist of 4%-6% spandex and 94%-96% mulberry silk. Sometimes, in a more general way, elastic silk fabrics are classified as silk.
Is cotton, hemp or silk better?
Personally, I think it depends on your needs. Silk is more comfortable to wear, and cotton and linen absorb sweat. hope this helps
Silk reference:
First: comfortable to wear. Silk is made of protein fiber, which has excellent biocompatibility with human body, smooth surface and the lowest friction coefficient to human body, only 7.4%.
Second: good moisture absorption and moisture release performance. Silk protein fiber is rich in amino (-CONH), amino (-NH2) and other hydrophilic groups, and because of its porosity, water molecules are easy to diffuse, so it can absorb or release water in the air and keep a certain amount of water. At normal temperature, it can help the skin retain a certain amount of moisture and will not make the skin too dry; When worn in summer, it can quickly release sweat and heat discharged by the human body, making people feel extremely cool. [4 1]
Silk not only has good heat dissipation performance, but also has good warmth retention. Its thermal insulation benefits from its porous fiber structure. There are many tiny fibers in a silk fiber, and these tiny fibers are composed of even smaller fibers. So the seemingly solid silk is actually more than 38% hollow, and there is a lot of air in these gaps, which prevents the heat from emitting and makes the silk have good warmth retention.
Third: sound absorption, dust absorption and flame retardant. Silk fabric has high porosity, so it has good sound absorption and air absorption performance. Besides making clothes, it can also be used for interior decoration, such as silk carpets, tapestries, curtains, wall cloths and so on. Because silk has the properties of moisture absorption, moisture release, moisture retention, air inhalation and porosity, it can also adjust indoor temperature and humidity and absorb harmful gases, dust and microorganisms. In addition, silk fiber has little thermal denaturation and is relatively heat-resistant. When heated to 100℃, the brittleness is only about 5~8%, and the thermal variability of most synthetic fibers is 4~5 times greater than that of silk. The burning temperature of silk is 300~400℃, which is a flame retardant fiber, while the burning temperature of synthetic fiber is 200~260℃, which is flammable and fusible. Therefore, using silk fiber as the raw material of interior decoration can not only play the role of sound absorption, dust absorption, heat preservation, but also play the role of flame retardant. [4 1]
Fourth: anti-ultraviolet. Tryptophan and tyrosine in silk protein can absorb ultraviolet rays, so silk has good anti-ultraviolet function. Moreover, ultraviolet rays do great harm to human skin. Of course, after absorbing ultraviolet rays, silk itself will undergo chemical changes, which will make silk fabrics easily yellow under the irradiation of sunlight.
Fifth: medical care. The health care function of silk fiber is irreplaceable. It contains 18 kinds of essential amino acids, which are almost the same as those contained in human skin, so it is also called the "second skin" of human beings. Wearing silk clothes can not only prevent ultraviolet radiation, harmful gas invasion and harmful bacteria, but also enhance the vitality of skin cells on the body surface and promote the metabolism of skin cells. At the same time, it has a good adjuvant treatment effect on some skin diseases. [4 1]
disadvantaged
Easy to wrinkle, easy to absorb, not strong enough, fast fading, unable to keep warm.
Cotton and linen reference:
Advantages:
First, breathe.
The heat dissipation performance of flax is five times that of wool and 19 times that of silk. In hot weather, wearing linen clothes can lower the skin surface temperature by 3-4 degrees Celsius than wearing silk and cotton fabrics.
Second, fuck.
Flax can absorb 20% of its own weight of water, at the same time, it can quickly release the absorbed water, and it can keep dry even if it sweats a lot.
Third, reduce perspiration.
Helps maintain the electrolyte balance of the human body. The research shows that linen clothing can reduce human perspiration 1.5 times than cotton clothing.
Fourth, radiation protection.
Modern people cannot live without computers and mobile phones, and radiation pollution is an inevitable problem for modern people. Japanese research shows that adding 20% flax to clothing fabrics can prevent 80% radiation. For white-collar workers, female friends who are ready to give birth and are pregnant for 3 months, and childless male friends are especially suitable.
Five, anti-static.
Only 10% flax in the blended fabric is enough to prevent static electricity. It can effectively relieve people's anxiety, headache, chest tightness, dyspnea and other symptoms caused by electrostatic environment.
Sixth, inhibit bacteria.
Flax has a good inhibitory effect on bacteria and fungi, and can effectively prevent some diseases. According to Japanese researchers, linen sheets can prevent bedsores in patients who have been in bed for a long time, and linen clothes can help prevent and treat some skin diseases, such as common rashes and chronic eczema. ...
How to distinguish true silk from false silk? Will silk be fuzz? Will it wrinkle?
There are many ways to identify silk, but they all need some experience and experience to be accurate.
1. Burning: Take out a piece of silk or cloth, and it will smell like burning hair after burning, because silk and hair are the same.
2, feel: silk feels soft and smooth, but it is not the kind of smooth without friction. Synthetic fibers such as polyester and nylon are too slippery, but not soft. Silk will feel a little "astringent" when rubbing against each other, which is called "silk sound" in our industry. This is a comfortable feeling peculiar to silk. Daqingshuyuan replied
3, silk is easy to wrinkle, which is also a feature, and it will wrinkle with a little force. And it's hard to get rid of it without water or ironing.
4, silk will still be fuzz, especially in parts that are often rubbed for a long time, such as underarms. Daqingshuyuan replied
What's the difference between silk and silk?
Silk is a textile fiber made from silk reeling.
Spun silk is the leftover from silk processing.
? Silk is the leftover of spun silk.
Simply put, spun silk is the leftover of real silk, which falls off during weaving.
What is the price of silk pajamas? Is it real silk?
First, observe the gloss.
The luster of silk fabric is soft and even, bright but not harsh. Although the polyester yarn has uniform luster, it has flash or bright silk. Rayon fabric is bright, but it is not soft. Nylon silk fabric has a poor luster, as if it were coated with wax.
Second, check the crease carefully.
Because of its good elasticity, silk will not wrinkle when it is loosened after being pinched by hand. Although nylon yarn can slowly recover to its original state, it also has creases. Don't be fooled by its false appearance. Man-made silk fabrics have obvious creases, and the creases are difficult to recover.
Third, the fiber test tension
Pull a few fibers at the edge of the fabric and wet them with water. If it breaks easily in a wet place, it means rayon, otherwise it is real silk.
