How to distinguish Elastic Tape For Bra The demolition of the two I do not know category Elastic Tape of the warp and weft yarns roots, parting with a lighter ignition, the ignition process to examine some of the physical scene, in recognition of the warp and weft yarns material. Have to leave in the ignition of the flame, the the solidification environment and exudes the smell, the ashes after ignition Survey of Development. Here is the two elastic webbing band material Ignition physical adhere to the parameters for each reference: Nylon webbing elastic: near flame that is collapsing melting fuel dripping and blistering straight inexhaustible fuel like celery taste hard, round, light brown to gray, beaded The polyester webbing: near flame collapsing melting fuel, dripping and foaming continued burning, a few have the smoke very weak sweetness hard round, black or brown Cotton fiber and hemp fiber Whenever, cotton fiber and hemp fiber near the flame that is burning, ignition rushed yellow flame, take the blue smoke.
The difference is both in the ignition odor and burn to ashes the cotton ignition disseminate the Paper smell, Ma ignition distributing plant ash smell; have some powder ashes after ignition, cotton, black or gray, hemp produces large amounts of off-white powder ashes. Second, nylon and polyester Daimyo polyamide fiber polyamide (nylon), near the flame that rushed curling melt into white gel melting fuel dripping and foaming in the flame, flame ignition, to sustained ignition from the armistice flame is difficult, exudes celery flavor, cooling After beige melt is not easy to crush.
Dacron the daimyo polyester fiber, easy Quchu near the flame that is collapsing edge solidified when the ignition while black smoke, yellow flame, emitting a fragrant odor, dark brown lumps after burning ashes, crush with your fingers. Three, acrylic and polypropylene (PP) Acrylic daimyo polyacrylonitrile fibers, near the fire to soften the the collapsing black smoke after the fire, the flame was white, rushed away from the flame ignition, sour odor exudes fire meat after burning ashes is not delineate black lumps, easy to hand-twist broken. PP the daimyo polypropylene fiber, near the flame that is collapsing, flammable, ignition rushing away from the fire and black smoke, flames upper end of the yellow, the lower end of the blue, exudes oil flavor, after burning ashes as hard and round fawn particles, easy to hand-twist broken. Fourth, polyvinyl alcohol, and polyvinyl chloride fiber The vinylon daimyo polyvinyl formal fibers, not easy Quchu, near flame melt shortening, the top of the flame ignition until the fibers blend into a gelatinous flame larger, thick black smoke, distributing bitter incense smell, after ignition, the residual black small bead-like particles, the fingers can be crushed.
Polyvinyl chloride fibers, polyvinyl chloride fiber daimyo and difficult fire, from the fire is put out, the flame is yellow, the lower end of the green white smoke emitting irritating pungent spicy sour, dark brown delineated lumps ashes after ignition, the finger is not easy to crush. , Spandex and Teflon Spandex daimyo polyurethane fibers, near the fire melting edge fuel, ignition flame is blue, continued to melt away the armistice fuel, emit a special pungent odor, soft loose ashes after ignition smudge. The Teflon the daimyo PTFE fiber, ISO organs called for fluorspar fiber, near the flame only solidified difficult to ignite, ignition, marginal flame was blue-green carbonization, melting and decomposition gas toxic as hard coagulum round black beads. Commonly used in sewing thread to create high-stick Teflon fiber in the textile industry. The ignition method screening fiber is simple, but the blended product is not easy to arbitrary. Obtained from the principles of the warp and weft (ie the principle of direct and cross) each collected a yarn and parting ignition Kam
