    FiberRibbonBlended Products

    How to distinguish and distinguish different kinds of ribbon?

    fibre

    Simple and easy, but blending products are not easy to judge.

    One yarn should be extracted from the warp and weft direction (that is, straight and pverse).

    The two kinds of weft yarns of unknown category weft are separated from each other by a lighter, and some physical phenomena are observed during the combustion process to determine the warp and weft yarns.

    raw material

    。

    When burning, we should observe the flame, melting and emission, and the state of burning ash separately.

    The following are two kinds of physical properties parameters of ribbon material for your reference.

    Nylon webbing: near flame, that is, melt, melt, burn, drop, and blister not to continue to burn. Celery tastes hard, round, light, brown to gray, and beads.

    Polyester ribbon: near flame is melt shrinkage, melting, burning, dripping and bubbling can continue to burn, a small number of cigarettes are very weak sweet hard round, black or light brown.

    Cotton fiber and hemp fiber

    Both cotton and hemp fibers are just burning near the flame, burning fast, the flame yellow, emitting blue smoke.

    The difference between the two odors and the ashes after burning is that

    Cotton burning

    Burning paper scent, burning out the smell of grass and ashes; after burning, cotton has very little powder ashes, black or gray, and a small amount of gray powder ashes.

    Two, nylon and polyester fiber

    Nylon (nylon) scientific name polyamide fiber, which is rapidly curled and melted into a white colloid near the flame, burns and bubbling in the flame. There is no flame in the combustion, and it is difficult to continue to burn away from the flame and emit celery flavor. After cooling, the light brown melts are not easy to be broken.

    Polyester fiber name is polyester fiber, easy to ignite, near the flame that melt shrinkage, burning when melting black smoke, a yellow flame, emitting aromatic odor, burned black brown hard lump, with fingers can be twisted.

    Three, acrylic and polypropylene (PP)

    Acrylonitrile polyacrylonitrile fiber, which melted and melted near the fire, ignited black smoke after burning. The flame was white, burning rapidly from the flame, emitting the bitterness of burning meat, burning ashes for irregular black lumps, hand twisting and fragile.

    Polypropylene fiber is known as polypropylene fiber, which is near flame, which is melted and flammable. It is flammable. It burns slowly from the fire and smoked black. The flame is yellow at the top and blue at the bottom, emitting oil smell. The burnt ashes are hard round brown, and the hands are twisted and fragile.

    Four, vinylon and polyvinyl chloride

    Polyvinyl formal fiber is not easy to ignite, and the flame is melted and contracted at the top. There is a little flame at the top of the flame. When the fibers are melted into a jelly flame, it has a thick black smoke and a bitter fragrance.

    The polyvinyl chloride fiber, known as the polyvinyl chloride fiber, is difficult to burn. It is extinguished from fire. The flame is yellow, and the lower part is green and white. It gives off pungent, pungent, sour taste. After burning, the ashes are dark brown, irregular hard lumps, and fingers are not easy to twist.

    Five, spandex and fluorine fiber

    The spandex name is polyurethane fiber. It burns near the edge of the fire. When it burns, the flame is blue, leaving the fire to continue to melt and emit a special pungent odor. After burning, the ash is soft and fluffy.

    Polytetrafluoroethylene (PTFE), known as fluorine fiber, is called fluorite fiber by ISO. It is only melting near flame. It is hard to ignite and burn. The edge flame is blue-green and carbonized and melted and decomposed. The gas is poisonous, and the melting material is hard round black bead.

    Fluorine fiber is commonly used in the textile industry to produce high-performance sewing thread.
