Silk generally refers to silk, including mulberry silk, tussah silk, ramie silk, cassava silk, etc. It belongs to protein fiber. Silk fibroin contains 18 kinds of amino acids beneficial to human body, which can help skin maintain the metabolism of surface lipid film, so it can make skin Keep moist and smooth, and have the reputation of human "second skin". Wearing silk clothes can also prevent ultraviolet radiation, prevent harmful gas from invading, resist harmful bacteria, and have a good auxiliary treatment for certain skin diseases. In addition, due to the special hygroscopicity and gas permeability, it also has the effect of regulating body temperature and regulating moisture. Faced with a variety of merchants shouting 100% silk in the market, in the era when the counterfeiters are pervasive and the anti-counterfeiting technology is unpredictable, how can consumers distinguish the authenticity in addition to the trust of major shopping malls and specialty stores?
Item number identification
Chinese satin implements a uniform number consisting of five Arabic numerals. The five digits start from the left and the first digit represents the material number of the fabric. The full silk fabric (including silk, silk) is "1", chemical fiber fabric. It is "2", the blended fabric is "3", the tussah silk fabric is "4", and the rayon fabric is "5". It is understood that there are no silk fabrics in the imported satin sold on the market, such as georgette, soft-streaked yarn, etc. These are chemical fiber fabrics, so the imported satin has no uniform product number.
Price identification method
Silk fabrics are relatively expensive, about twice or twice as much as chemical fiber and silk fabrics, but they are not expensive. They are just a recognition factor, or they must be multi-angled.
Gloss, hand recognition
The sample is evenly observed to observe the appearance. The silk has light absorbing properties. It looks smooth and does not have a mirror surface. The gloss is soft and elegant. The pearl is bright, the hand feels soft and elegant, the silk thread is dense, and the wrinkles are caught by hand. The higher the purity and the higher the density. The silk feels better; the silk fabric is processed, the hand feels softer, but the silk surface is dark and has no pearl luster; the chemical fiber fabric is bright and glaring, and the hand feels stiff. Rubbing the two layers of silk fabric, slightly scratching the hand.
Combustion recognition method
Take out some of the yarn ends for burning, the silk can not see the open flame, there is the smell of burning hair, indicating that there are protein fibers, silk ash into black particles, can be crushed by hand; simulation silk fires, fire plastic, fire extinguished The back edge will leave a hard rubber block. The silk shrinkage rate is higher. It is better to purchase the finished product to choose a larger size than the actual demand. If it is a fabric, the fabric should be immersed in clear water for more than 5 hours before the production, so that the fabric completely absorbs moisture and then dried. Soak the second time, so that the silk will not be deformed after two dipping and drying.
Tensile recognition method
The tension of the silk is poor and it is easy to be broken; the rayon is easily broken in the wet state; the chemical fiber is stronger in the wet and dry state. Friction-acoustic recognition rubs fabrics together, silk fabrics produce "silk-sounding" sounds, while fabrics of chemical fiber fabrics and other raw materials do not.
84 disinfectant identification method
In the experiment, chemical methods are usually used to identify: 1 ​​gram of silk scarves are placed in a 1 molar sodium hypochlorite solution, and if all are dissolved, it can be judged to be true silk. The main component of the 84 disinfectant is sodium hypochlorite, which encounters chemical reactions in which protein fibers are dissolved. In life, consumers can try 84 disinfectant to identify true and false silk. Use this method to pay attention to control the specific gravity. If the amount of disinfectant is not enough, the concentration is not reached, or some fabrics are tightly structured, and may not be completely dissolved.
In addition, at the same time as the eye of the eye, you also know how to pity the jade. The silk clothes after sweating should be washed immediately, and the silk dresses are woven with protein-like delicate health care fibers. It is not suitable for rubbing on rough articles and washing with washing machine. The clothes should be reversed, immersed in water at a temperature of 30 degrees below water for 5 to 10 minutes, and gently tapped with a special silk detergent or neutral soap. If a few drops of balsamic vinegar are soaked in water, the washed silk clothes are soft and smooth. After washing, it is not advisable to twist the water. It should be shaken gently, facing outwards, and placed in a cool, ventilated place to dry. Dry to 70% dry and then iron or shake. The ironing temperature is preferably 100 degrees, and it is better to put a lining cloth. When silk clothing is not worn, it is not advisable to put mothballs, otherwise it will be easy to embrittle.
