When purchasing various webbings, ribbons, or ribbons, it is a headache for us to distinguish between different types of webbing, ribbons, or ribbons. When we face this issue, we are often overwhelmed and we don't know much about related knowledge. Today, Jiashan Xiongzhen Button Factory Xiaobian is here to briefly introduce the method of distinguishing, and hope to help our friends, especially the clothing accessories.

The texture of the ribbon, ribbon or ribbon is different. It is simple and easy to use the combustion method to identify fibers, but the blended products are not easy to judge. It is necessary to burn one yarn from each of the warp and weft directions (ie, the straight and horizontal directions) to burn. A number of warp and weft yarns of two types of ribbons that are not known are removed and burned with a lighter. Some physical phenomena are observed during the combustion to determine the raw materials for the warp and weft yarns. When burning, observe the flame, the melting condition, the odor emitted, and the condition of the burned ash.
The following are the parameters of the physical properties of the combustion of ribbons, ribbons or satin materials. When using the combustion identification method, you can refer to them:
One, cotton fiber, hemp fiber cotton fiber and hemp fiber are just near the flame that is burning, burning rapidly, the flame was yellow, blue smoke. The difference between the burning odor and the burning ash is that the cotton burns a paper smell and the hemp burns out the ash odor; after burning, the cotton has very little powder ash, black or gray, and the hemp produces a small amount of grayish white powder ash.
Second, nylon and polyester nylon (nylon) scientific name of polyamide fiber, near the flame that quickly curled into a white gel, melting in the flame dripping and blistering, no flame when burning, difficult to continue to burn away from the flame, emitting Celery flavor, light brown melt after cooling is not easy to grind.
Polyester scientific name of polyester fiber, easy to ignite, near the flame that is melted down, burning side while melting black smoke, a yellow flame, emitting an aromatic smell, burning ash after the dark brown hard block, with your fingers can be crushed. Nylon Ribbon: Near flame is melted, melted, dripping and bubbling, not directly continue burning, like celery flavor, hard, round, light, brown to gray, beaded. Polyester webbing: Near flame is melted, ignited, drips and blisters, can continue burning, a small amount of smoke, very weak sweetness, hard round, black or light brown.
Third, acrylic and polypropylene (PP)
Acrylic name polyacrylonitrile fiber, near the fire softening and melting, black smoke after the fire, the flame was white, quickly burned from the flame, exudes the bitter taste of fire meat, burned as irregular black hard ash, handcuffs fragile .
Polypropylene Polypropylene fiber, near the flame that is melted, flammable, slowly burning from the fire and black smoke, the flame is yellow on the top, the lower end of the blue, emits the flavor of oil, burned after the ash is a hard round yellow-brown particles, easy to handcuffs broken.
4. Vinylon and Chrysene Vinyl Polyvinyl formal fiber, not easy to ignite, near the flame melting and shrinking, the top of the flame when burning, until the fiber is melted into a jelly flame becomes larger, there is thick black smoke, smell of bitterness After the combustion, black bead-like particles remain, which can be crushed with your fingers.
Lactose fiber name PVC fiber, hard to burn, away from the fire that is extinguished, the flame was yellow, the lower end of the green white smoke, irritating pungent pungent sour, burned after the ashes are dark brown irregular hard blocks, fingers are not easy to smash.
5. Spandex and Polyurethane Spandex Polyamide Polyurethane Fiber Named for Polyurethane Fiber, it burns near the fire side, burns when the flame is blue, leaving the fire to continue to ignite, emitting a special irritating odor, burning ash is soft fluffy black gray. Teflon scientific name PTFE fiber, ISO organization called it fluorite fiber, near the flame only melt, difficult to ignite, do not burn, the edge of the flame was blue and green carbonization, melting and decomposition, gas toxic, the melt is hard round black Beads. Fluorofibers are commonly used in the textile industry to make high-performance sewing threads.
There are these combustion-related identification methods to corroborate your initial judgments on the material, and generally you can achieve accurate resolution.
It is hoped that the above method for distinguishing textures of ribbons, ribbons or ribbons will help the purchase of friends, especially clothing accessories.
