How to distinguish webbing, ribbon and satin ribbon? The material difference of webbing, ribbon or satin ribbon. Generally, it is simple and easy to use the combustion method to identify fibers, but it is not easy to judge blended products. It is necessary to extract one yarn from the warp and weft directions (that is, the straight and horizontal directions) and burn them separately.
  
When purchasing various ribbons, ribbons or ribbons, how to distinguish between different types of ribbons, ribbons or ribbons is a headache. When faced with this problem, it is often at a loss, and there is not much knowledge about the relevant knowledge. Today, the editor of Buyigang buyigang.com is here to briefly introduce the method of distinguishing, and I hope it will be helpful to all friends, especially the purchase of clothing accessories.
  
The material difference of webbing, ribbon or satin ribbon. Generally, it is simple and easy to use the combustion method to identify fibers, but it is not easy to judge blended products. It is necessary to extract one yarn from the warp and weft directions (that is, the straight and horizontal directions) and burn them separately. Disassemble several warp and weft yarns of two unknown types of webbing and burn them with a lighter respectively. Observe some physical phenomena during the burning process to determine the raw material of the warp and weft yarns. When burning, observe the status of flame, melting, smell, and ashes after burning.
  
The following are the burning physical performance parameters of webbing, ribbon or satin materials. When using the burning identification method, they can be used for your reference:
  
1. Acrylic and polypropylene (PP)
The scientific name of acrylic fiber is polyacrylonitrile fiber. It softens and shrinks near fire. It emits black smoke after fire. The flame is white. After leaving the flame, it burns quickly. It emits the bitter smell of burning meat. After burning, the ashes are irregular black lumps, which are easily broken by hand twist. .
  
The scientific name of polypropylene fiber is polypropylene fiber, which melts near the flame and is flammable. It burns slowly and emits black smoke from the fire. The upper end of the flame is yellow and the lower end is blue, emitting a smell of petroleum. The ashes after burning are hard round light yellow-brown particles, which are easy to twist by hand. broken.
  
2. Nylon and polyester
  
The scientific name of nylon (nylon) is polyamide fiber. It quickly crimps and melts into a white gel near the flame. It melts and drops and foams in the flame. There is no flame when burning. It is difficult to continue burning without the flame. It emits a celery smell. After cooling down The light brown melt is not easy to grind.
  
The scientific name of polyester is polyester fiber, which is easy to ignite and melts when it is near the flame. When it burns, it emits black smoke while melting. It is a yellow flame and emits an aromatic smell. After burning, the ashes are dark brown lumps, which can be broken with fingers. Nylon webbing: near flame, it melts, melts, drips and foams, does not continue to burn, it smells like celery, hard, round, light, brown to gray, and bead-like. Polyester webbing: near flame, that is, it melts, melts, drips and foams, can continue to burn, a small amount of smoke, very weak sweetness, hard round, black or light brown.
  
3.Cotton fiber and hemp fiber
  
Both cotton fiber and hemp fiber burn immediately near the flame, burning quickly, the flame is yellow, and blue smoke is emitted. The difference between the burning smell and the ashes after burning is that the burning of cotton gives off the smell of paper, and the burning of hemp gives off the smell of plant ash; after burning, cotton has very little powder ashes, which is black or gray, and hemp produces a small amount of off-white powder ashes.
  
4. Spandex and fluorine fiber
  
The scientific name of spandex is polyurethane fiber. It melts while burning near the fire. The flame is blue when burning. It continues to melt away from the fire and emits a special pungent odor. After burning, the ashes are soft and fluffy black ash. The scientific name of fluorine fiber is polytetrafluoroethylene fiber, which is called fluorite fiber by ISO organization. It only melts near flame, hard to ignite, and does not burn. The edge flame is blue-green and carbonized, melted and decomposed. The gas is toxic, and the melt is hard round black. Beads. Fluorine fibers are often used in the textile industry to make high-performance sewing threads.
  
There are these burning-related identification methods to support your preliminary judgment on the material, and generally you can achieve accurate discrimination.
  
5. Vinylon and Chlorine
  
The scientific name of vinylon is polyvinyl formal fiber. It is not easy to ignite. It melts and shrinks near the flame. There is a little flame at the top when it burns. When the fiber is melted into a gelatinous flame, the flame becomes larger, with thick black smoke and a bitter smell. Bead-shaped particles can be crushed with fingers.
  
The scientific name of polyvinyl chloride fiber is polyvinyl chloride fiber. It is difficult to burn and extinguishes after leaving the fire. The flame is yellow, with green white smoke at the bottom, exuding a pungent, pungent and sour taste. After burning, the ashes are dark brown irregular lumps, and the fingers are not easy to twist.
