How to distinguish the materials between different kinds of ribbons, it is a headache when purchasing ribbons and is often at a loss when faced with this problem, and usually, we do not know related knowledge, here a brief introduction to the method of discrimination, we hope to help you, especially for your clothing accessories procurement.
Here we learn how to tell the following 5 kinds of materials ribbons:
1.Cotton and hemp fibers ribbon.
2.Nylon and polyester ribbon.
3.Acrylic and polypropylene ribbon.
4.Vinylon and Chlorine ribbon.
5.Spandex and fluorocarbon ribbon.
It is easy to distinguish the fiber by burning method, but not easy to judge the blended product. It is necessary to draw one yarn from each direction of the warp and weft, i. e. straight and horizontal. To determine the raw materials of warp and weft yarn, several warp and weft yarns of two unknown kinds of ribbon are separated and burned with lighters respectively. When Burning, we should observe the flame, the melting condition, the smell, and the condition of the Ashes after burning. The following are the physical properties of the ribbon material for reference when using the combustion-identification method:
1.Cotton and hemp fibers ribbon.
Cotton and hemp fibers are just near the flame is burning, burning quickly, flame-yellow, blue smoke. The difference between the smell of burning and the ash after burning is that cotton gives off paper smell and hemp gives off plant ash smell. After burning, cotton has very little powder ash, which is black or gray, and hemp produces a small amount of ash.
2.Nylon and polyester ribbon.
Nylon (nylon) Polyamide fiber near the flame is quickly rolled into a white gel, in the flame burning drops and Bubbles, burning without flame, the flame can not continue to burn, emitting celery smell, after cooling, the light brown molten material is not easy to grind. The polyester fiber, easy to ignite, near the flame that is melting, burning side of the melting side of black smoke, yellow flame, emitting an aromatic smell, after burning ashes for black-brown hard block, with fingers can be crushed. Nylon webbing: Near Flame namely melting, melting, dripping, and foaming, not directly burning, like celery smell, hard, round, light, brown to gray, bead. Polyester Ribbon: Near Flame namely melting, melting, dropping, and foaming, can continue to burn, a few have a smoke, very weak sweet, hard round, Black, or light brown.
3.Acrylic and polypropylene ribbon.
Polyacrylonitrile fiber, near the fire-softening melting shrinkage, black smoke after the fire, the flame was white, from the flame after burning quickly, emitting a sour smell of burning meat, burning ashes for irregular black hard pieces, hand-twisted fragile. The polypropylene fiber, near the flame that is melting, flammable, from the fire burning slow and black smoke, flame upper-end yellow, lower-end blue, emitting oil smell, burning ashes for hard round light yellow-brown particles, hand twist fragile.
4.Vinylon and Chlorine ribbon.
Vinylon Formvar, not easy to ignite, near flame melting shrinkage, burning when there is a little flame at the top until the fiber is melted into a gel flame bigger, there is thick black smoke, emitting a bitter smell, burning left black beads like particles, crush with your fingers. Polyvinyl chloride fibers, difficult to burn, out of the fire, the flame was yellow, the lower end of the green smoke, emitting a pungent acrid smell, burning ashes for black-brown irregular lumps, fingers are not easy to crush.
5.Spandex and fluorocarbon ribbon.
Polyurethane fiber, near the edge of the fire melting edge burning, the flame was blue, leaving the fire to continue melting, emitting a special pungent odor, burning ashes for soft fluffy black ash. Polytetrafluoroethylene fiber, also known as fluorite fiber, near the flame only melting, difficult to ignite, not burning, the edge of the flame was blue-green carbonization, melting, and decomposition, gas toxic, melting for hard round black bead. Fluorocarbon fiber is often used in the manufacture of high-performance sewing thread in the textile industry.
All in all, learning to distinguish different ribbon materials will help us distinguish quality and understand ribbon material characteristics in different application scenarios.
