What is ribbon?
Webbing Ribbon is made of various yarn as raw material of narrow-shaped fabrics or tubular fabrics. With a wide variety of fabrics, widely used in apparel, footwear, luggage, industry, agriculture, munitions, transportation and other industrial sectors. The development of the Ribbon is a long history, the 30, the ribbon is handmade weaving ribbon exquisite picture production, raw materials for cotton, twine. After the founding of New China, ribbon of raw materials gradually developed to nylon, Vinylon, polyester, polypropylene, spandex, viscose and so on, the formation of woven, knitted, knitting three kinds of technology, fabrics have plain weave, twill, satin, jacquard, double-decker, multi-layer, tubular and joint organization.
How to distinguish ribbon?
Webbing Weaving the ribbon is a lot of raw materials, so how to distinguish the weaving of the production of raw materials? In fact, very simple, just two types of woven ribbon of the warp and weft yarn splitting the roots, respectively with a lighter combustion, combustion process to observe some physical phenomena to determine the weft yarn raw materials. Combustion should be separately to the flame, melting situation and emitting the smell, burning ash after observation.
Here are the two types of ribbon materials for the physical properties of combustion parameters for your reference:
Nylon Ribbon: Near flame melting-melting, dripping and foaming not directly to continue burning like celery flavor hard, round, light, brown to gray, bead-like
Webbing Polyester Ribbon: Near flame melting, melting, dripping and foaming can continue to burn, a handful of strong sweet smoke weak hard round, black or pale brown
Webbing Folding cotton fibres and hemp fibers:
Fiber and hemp fibers are just near flame burning, burning quickly, the flame is yellow, and risking blue smoke. The difference between the two burning smells and burning Ashes is that cotton burns emit paper odor, hemp combustion emits vegetation ash odor; After burning, the cotton has little powder ash, is black or gray, hemp produces a small amount of gray white powder ash.
Webbing Folding Nylon and polyester:
Webbing Nylon (nylon) scientific name polyamide fiber, near the flame is rapidly shrinking into a white glue, melting in flames and bubbling dripping, burning without flames, leaving the flame difficult to continue burning, emitting celery flavor, cold light brown melt not easy to grind.
Polyester polyester fiber, easy to ignite, near the flame is melting, burning when the edge melting side to take black smoke, a yellow flame, emitting aromatic smell, burned ashes to black brown hard block, with the fingers can be twisted.
Folding acrylic and polypropylene (PP):
Webbing Acrylic fiber name polyacrylonitrile fibers, near the fire softening melt shrinkage, fire after the smoke, flame white, from the flame after the rapid combustion, emitting a bitter smell of burning meat, burned ashes for irregular black, hand twist fragile.
Webbing Polypropylene fiber scientific name, near flame melting, flammable, burning slowly from the fire and smoke, the flame is yellow, the lower end of blue, emitting the oil smell, burned ashes for the hard round pale yellow brown particles, hand twist fragile.
Folding Vinylon and Shang:
Webbing Polyvinyl alcohol, the scientific name of formaldehyde fiber, not easy to ignite, near the flame melting shrinkage, burning at the top of a little flame, to the fiber melts into a rubber-like flame, there is thick black smoke, emitting bitter smell, burning after the remaining small bead-like particles, the use of finger crush.
Shang Scientific name PVC fiber, difficult to burn, out of the fire, the flame is yellow, the lower end of green white smoke, emitting pungent pungent sour, burning ashes to dark brown irregular hard pieces, fingers are not easy to twist.
Folding spandex and fluorine LUN:
Webbing Polyurethane polyester polyurethane fiber, near the flame side melting, combustion when the flames are blue, leaving the fire to continue melting, emitting a special irritating odor, burning ashes for soft fluffy black ash. Fluorine LUN scientific name Teflon fiber, ISO organization called fluorite Fiber, near flame only melting, refractory ignited, not burning, the Edge flame is blue and green carbonization, melting and decomposition, gas toxic, melting material for the hard round black bead. Fluoride fiber In the textile industry is often used to make high-performance sewing threads.
Webbing It is easy to distinguish fibers by combustion method, but the blended products are difficult to judge. One yarn should be burned separately from the direction of latitude and longitude (i.e. straight and transverse direction).
