Silk fabric identification tips

Silk generally refers to silk, including mulberry silk, oak silk, castor silk, cassava silk, etc., which belong to protein fiber, and silk fibro contains 18 kinds of amino acids that are beneficial to the human body, which can help the skin maintain the metabolism of the surface lipid film, so it can keep the skin moisturized and smooth, and has the reputation of human “second skin”. Wearing silk clothes can also prevent ultraviolet radiation, prevent harmful gas intrusion, resist harmful bacteria, and have a good adjuvant treatment effect on some skin diseases. In addition, due to its special hygroscopicity and breathability, it also regulates body temperature and moisture. In the face of a variety of merchants shouting 100% silk in the market, in this era of pervasive counterfeiters and inscrutable counterfeiting technology, how can consumers distinguish authenticity in addition to their trust in major shopping malls and specialty stores?
Product number identification
Chinese silk satin implements a unified product number composed of 5 Arabic numerals, these 5 digits from the left The first digit represents the material number of the fabric, all silk fabrics (including mulberry silk and silk silk) are “1”, chemical fiber fabrics are “2”, blended fabrics are “3”, oak silk fabrics are “4”, and rayon fabrics are “5”. It is understood that there are no silk fabrics in the imported silk satin sold on the market, such as georgette, soft yarn beaded pattern, etc., which are all chemical fiber fabrics, so there is no unified product number for imported silk satin.
Price identification method The price of
silk fabric is relatively expensive, about twice to twice that of chemical fiber and imitation silk fabrics, but it is not expensive or silk, which is only an identification factor, or to identify and judge from multiple angles.
Luster and feel recognition method
Spread the sample flat to observe the appearance, silk has light-absorbing performance, looks smooth and not mirrored, the luster is elegant and soft, pearl light, the feel is soft and elegant, the silk thread is dense, there will be wrinkles when you grasp it by hand, the higher the purity, the greater the density of silk, the better the feel; Although the imitation silk fabric has been treated and feels soft, the silk surface is dark and has no pearl luster; Chemical fiber fabrics have a bright luster and dazzling, and they feel stiff. Rub two layers of silk fabric together to create a slight scratching feeling.
Combustion identification method
Take out part of the yarn thread for burning, the silk cannot see the open flame, there is a smell of burning hair, indicating that there are protein fibers, silk ash into black particles, can be crushed by hand; The simulated silk has a plastic smell when it catches fire, and after the fire is extinguished, a hard glue block will be left on the edge. If it is a fabric, the fabric should be soaked in clean water for more than 5 hours before production, so that the fabric can completely absorb the water and then dry, and then soak it for the second time, so that the silk will not deform after two soaks and two drying.
Tensile identification method The tensile force of
silk is poor, and it will be easily broken; Rayon is easy to break in a wet state; Chemical fibers are relatively strong in both wet and dry states. The friction sound recognition method rubs the fabrics against each other, and the silk fabric will produce a “silk sound” sound, while the fabric of chemical fiber fabrics and other raw materials does not have this sound.
84 Disinfectant Identification Method In
experiments, chemical methods are usually used to identify: put 1 gram of silk scarf fiber into 1 mole of sodium hypochlorite solution, and if all of it is dissolved, then it can be determined that it is true silk. 84 The main ingredient of disinfectant is sodium hypochlorite, which will produce a chemical reaction of dissolution when encountering protein fibers. In life, consumers can try 84 disinfectant to identify real and fake silk. If the amount of disinfectant is not enough, the concentration is not reached, or some fabrics have a tight structure, they may not be able to dissolve completely.
In addition, while discerning the beads, we must also know how to cherish the fragrance and jade. Silk clothes should be washed immediately after sweating, silk clothes are woven from protein delicate health fibers, and should not be rubbed on rough items and washed in the washing machine. The clothes should be soaked in clean water for 5———10 minutes below 30 degrees water temperature, and gently rubbed with special silk detergent or neutral soap. If you soak a few drops of balsamic vinegar in water, the washed silk clothes will be soft and smooth. After washing, it should not be twisted to remove the water, it should be gently shaken off, turned outward, and placed in a cool and ventilated place to dry. Let it dry until it is 70% dry, then iron or shake it flat. The ironing temperature should be 100 degrees, and it is best to put on an interlining. When silk clothes are not worn, it is not advisable to put mothballs, otherwise it is easy to become brittle.
