Silk Hard Index Has Three Products To Buy.

< p > silk, as a symbol of China's 5000 years of civilization, has been spread to Persia and other countries in the Tang Dynasty. With its excellent handle and fine workmanship, silk has won the love of consumers at home and abroad, especially the cheongsam with Chinese national characteristics. Most of them are made of silk material. < /p >
< p > < strong > true and false identification < /strong > < /p >
< p > silk is divided into two kinds of silk and imitation silk, the difference is: < /p >
< p > identification number < /p >
< p > China made silk fabric is a uniform product made by China National Silk Corporation. The product number is made up of 5 Arabia figures. The first digit on the left shows the variety of the material: the pure silk fabric (including mulberry silk and spun silk) is "1", the chemical fiber fabric is "2", the mixed a target= "_blank" href= "http://www.91se91.com/" > the textile < /a > the object is "3", the tussah silk fabric is "4", the artificial silk fabric is "5", the interwoven material (including the acetate silk fabric) is 6, and the quilt fabric is "7". < /p >
< p > gloss, hand recognition < /p >
< p > pure silk fabric has elegant pearl luster and soft and elegant handle. The synthetic fabric has bright, dazzling and strong feel. Some silk fabrics feel soft, but the silk is dark and has no pearl luster. < /p >
< p > two simple methods < /p >
< p > a piece of clothing or a piece of < a target= "_blank" href= "http://www.91se91.com/" > clothing < /a >, to determine whether it is silk, cotton, linen, wool or man-made fiber, it is generally judged by experience. Such as long-term contact with all kinds of fabric salesmen, sewing workers, and so on, because of long-term experience and experience, you can see what material you can determine the fabric. Synthetic fibers are numerous. Nylon, polyester, viscose fiber super filament and special shaped silk can be made into simulated silk, which is false enough to be true. Therefore, we must use a variety of methods, comprehensive analysis and research, in order to arrive at an accurate conclusion. For example, combustion identification method, microscopic observation and identification method, dissolution identification method, chemical coloring identification method, melting point differential identification method and infrared spectrum identification method, etc. < /p >
< p > then, consumers do not have the necessary testing conditions. How to identify the authenticity of silk? Let's introduce two simple methods: < /p >
< p > (1) hand feeling method: < /p >
Less than P > 1., the silk has bright pearl luster and soft luster. The fabric of chemical fiber is not soft and bright. < /p >
< p > 2.. Silk fiber is slender and long, cotton fiber is short, and wool is curly. Chemical fiber is of good uniformity. < /p >
< p > 3. hand feeling method: silk feels soft, close to skin and smooth and comfortable. < /p >
< p > (two) combustion method: < /p >
< p > 1.. When burning, the silk has burning feather flavor, and it is difficult to continue burning. It will extinguish itself. Ashes are fragile, crisp, fluffy and black. < /p >
< p > 2. rayon (viscose fiber) has burning paper mixed with chemical smell when burning. It's burning fast. Ashes are ash free except for those without light. < /p >
< p > there are a little gray ash. < /p >
< p > 3. cotton and polyester fibers have very weak sweetness when burning. They do not burn directly or continue to burn slowly. The ashes are hard and round and become beads. < /p >
< p > 4. cotton and linen have the smell of burning paper, the ashes are soft and black gray. < /p >
< p > 5. wool burns almost the same as silk. Visual observation shows that the two are different. < /p >
< p > silk and health care < /p >
< p > since ancient times, silk has the reputation of "Silk Queen". In modern times, people also give it the reputation of "healthy fiber" and "health care fiber". Therefore, the health care function of silk fiber can not be compared to any fiber, and can not be replaced. Silk fiber contains 18 kinds of amino acids essential for human body, which is almost the same as the amino acids contained in human skin. Therefore, it also has the reputation of human "second skin". Wearing silk, < a target= "_blank" href= "http://www.91se91.com/" > clothing < /a >, can not only prevent ultraviolet radiation, prevent harmful gas invasion, resist harmful bacteria, but also enhance the vitality of skin cells, promote the metabolism of skin cells, and have a good auxiliary therapeutic effect on some skin diseases. In addition, because of the special hygroscopicity and permeability, it also regulates body temperature and regulates moisture. < /p >
< p > {page_break} < /p >
< p > now, silk bedding has also been found in home textile products. Some scientists say that long term use of silk products can improve the protein of the skin and have a good health care function for the human body. For this reason, a group of consumers began buying silk products. Silk products are expensive because their raw materials are difficult to collect, so consumers need to pay attention to these three rigid indicators when purchasing silk products. < /p >
< p > < strong > raw material index of silk < /strong > /p >
< p > buy silk bed products. There must be some identification of the raw materials on the bed. Consumers should learn to check the ingredients of raw materials, such as the amount of silk material, whether there are harmful substances in the interior and so on. Of course, consumers can ask shopkeepers to take out corresponding certificates to prove that these products are all made of silk. < /p >
< p > < strong > the comfort of silk is less than /strong > /p >
< p > silk feels smooth and has no sense of piercing and stabbing hands. If consumers feel such discomfort when purchasing < strong > a href= "http://www.91se91.com/" > silk < /a > /strong > product, it is definitely not pure silk products or other substances in bed products. This is a hazard to the physical and mental health of consumers. < /p >
< p > < strong > the lustre and appearance of silk bedding is less than /strong > /p >
< p > if pure silk products, < strong > a href= "http://www.91se91.com/" > bed /a < /strong > the material is very bright, and the appearance is beautiful, it will have a bright feeling to see it. Rather than pure silk products, the gloss should be a lot of bleak, and the appearance can be done in a timely fashion. Consumers must make sure that the brightness of silk bed products is inherent. Some small businesses deliberately add some brightening additives in order to highlight this effect. These methods are undesirable, and consumers can complain to the relevant departments if they find them. < /p >
