Ribbon is essentially made of a variety of yarn as raw materials made of narrow fabric or tubular fabric accessories. The modern production of ribbon has many bright eyes and different functions. It is widely used in the garment industry, footwear industry, luggage industry and so on.
Today I want to introduce to you how to identify the method of ribbon.
The two kinds of warp and weft yarn do not know the category of ribbon out of several, respectively with a lighter burning, burning process to observe some physical phenomena, in order to determine the raw material of warp and weft yarn. When burning, we should observe the flame, melting condition and smell, and the condition of the ashes after burning.
The following are the combustion physical performance parameters of two kinds of ribbon materials for your reference:
Nylon webbing: near flame that melt melt burning, dripping and foaming do not directly continue to burn like celery flavor hard, round, light, brown to gray, beaded
Polyester webbing: near flame melting melting flame, dripping and foaming can continue to burn, a few smoke very weak sweet hard round, black or light brown
Cotton fiber and hemp fiber
Cotton fibers and hemp fibers are just near the flame is burning, burning quickly, the flame is yellow, blue smoke. The difference between the smell emitted by burning cotton and the ash after burning is that the smell of paper is emitted by burning cotton, and the smell of wood ash is emitted by burning hemp. When burned, cotton has very little powder ash, which is black or gray, while hemp produces a small amount of gray powder ash.
Nylon and polyester
Nylon (nylon) the scientific name of polyamide fiber, near the flame is rapidly melting into a white glue, melting in the flame dripping and foaming, burning without flame, leave the flame difficult to continue burning, sending out celery flavor, after cooling light brown melt is not easy to grind.
Polyester fiber, the scientific name of polyester fiber, easy to ignite, near the flame is melting, burning side melting side black smoke, yellow flame, emitting aromatic smell, after burning the ashes into black brown hard block, can be broken with fingers.
Acrylic and polypropylene (PP)
Acrylic scientific name polyacrylonitrile fiber, near fire softening melting contraction, fire after black smoke, flame is white, from the flame after rapid combustion, exhale the bitter smell of fire meat, after burning ashes for irregular black hard block, hand twist fragile.
Polypropylene fiber, the scientific name of polypropylene fiber, near the flame that melt shrink, flammable, from the fire burning slowly and black smoke, the upper end of the flame yellow, the lower end of the blue, emitting petroleum flavor, after burning the ashes for hard round light yellow brown particles, hand twist fragile.
Vinylon and Chlorylon
Willian polyvinyl formaldehyde fiber, not easy to ignite, near flame melting contraction, burning at the top of a little flame, when the fibers are melted into a colloidal flame becomes larger, there is thick black smoke, emitting bitter aroma, the remaining black beads after burning, can be crushed by fingers.
The scientific name polyvinyl chloride fiber, difficult to burn, from the fire is extinguished, the flame is yellow, the lower end of the green and white smoke, emitting pungent and spicy sour taste, after burning the ashes for black brown irregular hard block, fingers are not easy to break.
Spandex and flon
Spandex scientific name polyurethane fiber, near the fire side melting side burning, burning flame was blue, leave the fire to continue melting, emitting a special irritant smell, after burning ash for soft fluffy black ash. Fluoron scientific name polytetrafluoroethylene fiber, ISO organization called it 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 beads. Flon fiber is often used in the textile industry to manufacture high performance sewing thread.
It is easy to identify fiber by combustion method, but it is difficult to judge blended products. One piece of yarn has to be drawn from the warp and weft directions (i.e. straight and horizontal) and burned separately
