How to distinguish to distinguish different kinds of ribbon?Differential fiber by combustion method is simple, but blended product is not easy to judge.From warp/weft direction (i.e., straight and horizontal direction) to extract a root yarn were burning.Will two categories ribbon of warp/weft yarn break several root, with lighter burning, burning process to observe some physical phenomena, to determine the raw materials of warp/weft yarn.To respectively on the flame combustion, melting and send out the smell, the status of the ash after burning.
In a variety of yarn as raw material made as narrow fabric or tubular fabric.With fabric variety, widely used in clothing, shoes, bags, industry, agriculture, military, transportation and so on various industry sectors.30 s, the ribbon is manual mill production, raw materials for cotton, hemp fiber.Gradual development after the founding of new China, the ribbon with raw material to the nylon, whalen, polyester, polypropylene fiber, spandex, viscose, etc., to form three categories of weaving, knitting, knitting technology, has tabby, twill, satin, jacquard fabric structure, double, multilayer, tubular and joint tissue.
Now the ribbon enterprise many, all have a lot of ribbon factory, traders, is one of the most centralized places in guangzhou, dongguan, quanzhou, yiwu, wenzhou, etc., because local advantage across different, the price is different also, guangzhou with textile city ribbon manufacturer focus all over the country, uneven quality, quanzhou areas across the country belongs to the mid-range, with high-grade ribbon, yiwu as raw materials, some advantages of artificial partial perfection.
The following by Silicone Printing Manufacturer to introduce two kinds of physical performance parameters of the combustion of ribbon material, for your reference:
Nylon ribbon: nearly flame combustion, shrink of molten drop and blister is not direct combustion Like celery flavour is hard, round, light, brown to gray, bead
Polyester ribbon: nearly flame combustion, shrink of molten drop and foaming can continue burning, smoke a few very weak sweetness Hard round, dark or light brown
A, acrylic and polypropylene (PP)
Scientific name acrylic polyacrylonitrile fiber, near fire softening melting and smoke after the fire, with a white flame, quickly after the flame burning, send out a fire to the bitter smell of meat, after burning ashes for irregular black lumps, hand twist is fragile.
Polypropylene scientific name of polypropylene fiber, near flame namely shrinkage, flammable, burning slowly and smoke from the fire, flame upper yellow, bottom, blue emitting oil smell, burning ashes as hard round fawn particles, after hand twist is fragile.
Second, polyamide and polyester
Scientific name polyamide fiber, polyamide (nylon) near flames shot curled fused white colloidal, namely in the flame melt dripping and sparkling, burn without fire, leave the flame burning hard, send out a celery flavour, beige molten material not easy pulverization after cooling.
Scientific name dacron polyester fiber, easy to ignite, near flame namely shrinkage, melting and smoke during burning, yellow flame, fragrant smell, burning after the ashes for dark brown lump, can twist with your fingers.
Three, whalen and chlorofibre
Scientific name whalen polyvinyl formal fibre, is not easy to ignite, nearly flame melt contraction, the top is a little flame, burning for fiber blending gelatinize flame, with thick black smoke, bitter sweet smell, small black bead particles left after burning, available fingers crush.
Scientific name chlorofibre PVC fiber, difficult to burn, the fire is out, the flame is yellow, the bottom green white smoke, pungent irritant spicy sour, after burning ashes for the dark brown irregular lumps, fingers twist not easily broken.
Four black silk ribbon, spandex and fluorine
Spandex scientific name polyurethane fiber, near the fire burning, burning flame is blue, leaving the fire continues to melt, send out a special irritating odor, ashes for soft fluffy black ash after combustion.Scientific name fluorine nylon ptfe fiber, ISO organization called fluorite fiber, flame only melt, difficult ignition, not burning, edge of the flame is blue, green, carbide melt and decomposition of toxic gas, melt for hard round black beads.Fluorine nylon fiber in the textile industry is often used in the manufacture of high performance sewing thread.
Five, the cotton fiber and hemp
Cotton and hemp are just near the flame is burning, burning rapidly, flame, yellow, blue smoke.The smell of burning and after burning ashes, is the difference between the cotton paper smells like burning, burning plant ash smells;After combustion, cotton has little powder ash, a black or gray, hemp produces a small amount of ash gray powder.
