How To Distinguish Polyester Silk Yarn From Real Silk

　　The characteristic of polyester silk yarn is that it can withstand chemical substances and frequent washing, reducing the appearance of fading and decolorization of clothes. Therefore, hotel uniforms, stone-milled blue denim clothing, sportswear, or children's clothing will be made of polyester silk yarn.

　　The shrinkage rate of real silk is relatively high. It is advisable to choose a standard that is one grade larger than the actual needs when purchasing products. Soak for the second time, so that the silk will not be deformed after two dips and two dryings, and the clothes can be washed at will. Relatively speaking, polyester silk yarn is tougher than artificial silk. When embroidering, the machine runs at a high speed, and the high-toughness polyester silk yarn can withstand greater tension, and its fireproof function is extremely high, even if the clothes are close to the flame, it is not easy to catch fire. So how to distinguish polyester silk yarn from real silk, here are a few tips to help you solve this problem:

　　Product number identification method: Domestic silk and satin implement a consistent product number consisting of 5 Arabic numerals. The first digit of the 5-digit number from the left represents the material number of the fabric, "1" for all silk fabrics, "2" for chemical fiber fabrics, and "2" for chemical fiber fabrics. "3" for blended fabrics, "4" for tussah silk fabrics, and "5" for artificial silk fabrics.

　　Quotation identification method: The price of real silk fabric is about twice that of chemical fiber and imitation silk satin.

　　Gloss and feel identification method: Spread the sample flat to observe its appearance. Silk has the function of absorbing light. It looks smooth and does not look like a mirror surface. The luster is elegant and soft, showing pearly light. , the higher the purity and the greater the density of silk, the better the hand feel; although the imitation silk fabric has been treated with hardening, it feels softer, but the silk surface is dark and has no pearly luster; chemical fiber fabrics are bright and dazzling, and feel stiffer. Silk products should have a slight scratching feeling. When two layers of fabrics are rubbed against each other, there will be a "silk buzzing" sound, but fabrics of other materials do not.

　　Combustion method: Take out part of the yarn and burn it. The real silk cannot see the open flame and has the smell of burning hair. The silk gray becomes black particles and can be crushed by hand; when polyester silk yarn catches fire, it ignites and has a plastic smell. Leave a hard glue block.
