Home textile suppliers teach you pure silk and imitation silk identification method Tonda home textiles co. , LTD
Pure silk and silk imitation silk two kinds, the difference methods are: number one, quality identification of domestic silk TongYiPin formulated by the implementation of the China national silk corporation. Product number is composed of five digits, first on the left figures show that the material varieties: complete real silk fabric ( Including mulberry silk, spun silk) As a '1', chemical fiber fabrics for '2', blended fabric is '3', tussah silk fabric as the '4', rayon fabric for '5', interwoven fabric, Including acetate silk) For '6', quilt cover fabric for the '7'. 2, luster and feel identify complete real silk fabrics is quiet and tastefully laid out and pearl luster, feel soft and elegant; Chemical fiber fabric luster bright, dazzling, feel is proofed. Although some emulation silk fabric feel soft, but the silken face dark, no pearly luster. Silk in the identification of a set of bedding covered 4 times, to determine whether the silk, cotton, linen, wool, or synthetic fiber, usually by experience. Such as long-term exposure to various kinds of fabric salesman, sewing worker, because long-term contacts and rich experience to see the hand can determine what bedding materials. But now many synthetic fiber. Polyamide, polyester, viscose filaments and heterotypic silk, simulation can be made into silk, foot realistic-looking, alone to see the hand is hard to determine its authenticity. Therefore, to use a variety of methods, comprehensive analysis and research, in order to accurate conclusions. Such as: combustion identification method, a microscope to identify method, dissolved method, chemical coloring identification method, melting point difference identification method and infrared spectrum identification method and so on. Then, consumers have no necessary test conditions, how to identify the authenticity of a silk? Down to introduce two simple methods: experienced people, hand touch soon will be able to distinguish, feels soft and smooth, but don't like plastic that waxy slippery feeling. A handful, loosen your hands, very wrinkled. And simulation silk is the polyester, flexibility is very good, catch a loosen your hand what all don't leave. In addition, the pure silk feels warm in winter and cool in summer, very comfortable. And the simulation silk feels, summer is very hot, cold in winter. Burning method is most convenient and effective. Pure silk take out a piece of gauze, burning with the smell of burning hair, because they are all protein fiber. And polyester is the petrochemical products, the smell of fire to burn the candle, almost there is hard granule residue after burning. Staining method, this is not suitable for the general consumers. Pure silk is very easy to dyeing, almost all dye can easily go. Simulation of silk and polyester, is almost invulnerable, any dye dyeing under normal temperature will not come up, after dye, one clear water wash it off. What are the characteristics of pure cotton products? On home textile products, everyone is preferred in pure cotton products. So what are made of pure cotton specific characteristic charm let everyone so favour it? Now the characteristic of small make up to sort out some cotton products to share with everyone. Hygroscopicity: cotton fiber has good hygroscopicity, under normal circumstances, around the fiber to absorb the moisture in the atmosphere, the moisture content of 8 - 10%, so it is in contact with a person's skin, make the person feels soft and not stiff. If cotton goods increasing humidity, ambient temperature is higher, the fiber contained in the amount of water will evaporate all dispersed, keep cotton water balance, make the person feels comfortable. Moisturizing effect: as the cotton fiber is a poor conductor of heat and electricity, heat conduction coefficient is extremely low, and because of the cotton fiber porous, high elasticity, between fiber can accumulate a large amount of air, air is a poor conductor of heat and electricity, so the cotton fibre has a good moisturizing effect, using pure cotton products make people feel warm. Products can good heat resistance, heat resistance: cotton under 110 ℃, the temperature of 0 degrees Celsius will only cause fabric on evaporation, water will not damage fiber, so pure cotton products used at room temperature, such as washing and dyeing is no influence to products, thus to improve the performance of pure cotton products and durable. Alkali resistance: cotton fiber on the alkali resistance is bigger, cotton fiber in alkaline solution, the fiber damage occur, the performance is conducive to taking the pollution after washing, disinfection impurities, at the same time can also be made of pure cotton for dyeing, printing and all kinds of processing technology, to produce more new cotton varieties. Health: cotton is a natural fiber, its main composition is cellulose, and a small amount of waxy substance and nitrogen content and pectic substances.
