When purchasing various ribbons, ribbons or ribbons, how to distinguish between different kinds of ribbons, ribbons or ribbons is a headache. It is often difficult to face this problem, but not much knowledge about related knowledge. Xiaobian here briefly introduces the method of distinguishing, and hopes to help all friends, especially the purchase of clothing accessories.

The difference in the material of the ribbon, ribbon or ribbon. It is generally easy to use the combustion method to identify fibers, but blended products are not easy to judge. It is necessary to extract a single yarn from each of the warp and weft directions (ie, the direction of the straight and the horizontal). The warp and weft yarns of the two unknown types of webbings were taken out and burned with a lighter, and some physical phenomena were observed during the burning process to determine the raw materials of the warp and weft yarns. When burning, observe the flame, the melting condition, the emitted odor, and the condition of the burnt ash.

The following are the physical properties of the burning of ribbons, ribbons or satin materials. When using the combustion identification method, you can refer to it:

First, cotton fiber and hemp fiber

Both cotton fiber and hemp fiber are burning near the flame, burning rapidly, the flame is yellow, and blue smoke is emitted. The difference between the odor of burning and the ash after burning is that the cotton burns to emit a paper odor, and the numbness emits a ash ash; after burning, the cotton has very little powder ash, which is black or gray, and the hemp produces a small amount of grayish white ash.

Second, nylon and polyester

Polyamide (nylon), the name of the polyamide fiber, is rapidly curled into a white gel in the near flame. It melts and blisters in the flame. There is no flame when burning. It is difficult to continue burning after leaving the flame, and it emits celery flavor. After cooling. The light brown melt is not easily broken.

Polyester fiber name is easy to ignite. It is melted near the flame. When burning, it emits black smoke when it melts. It has a yellow flame and emits an aromatic odor. After burning, the ash is a black-brown hard block, which can be broken with fingers. Nylon Ribbon: Near flame is melted, melted, dripped and foamed, not directly burned, like celery, hard, round, light, brown to gray, beads. Polyester webbing: Near flame is melted, melted, dripped and foamed, can continue to burn, a few smoke, very weak sweetness, hard round, black or light brown.

3. Acrylic and polypropylene (PP)

Acrylic fiber name polyacrylonitrile fiber, near fire softening and melting, black smoke after the fire, the flame is white, burning quickly after the flame, emitting the bitter smell of fire meat, after burning, the ash is irregular black lumps, handcuffs are brittle .

Polypropylene fiber, polypropylene fiber, near the flame is melted, flammable, burning slowly from the fire and black smoke, the upper end of the flame is yellow, the lower end is blue, emitting oily smell, after burning, the ash is hard round light yellow brown granules, hand 捻 easy broken.

Fourth, vinylon and polyvinyl chloride

The name of vinylon is not easy to ignite, the near flame melts and shrinks, and there is a little flame at the top when burning. When the fiber melts into a gelatinous flame, it has a thick black smoke, a bitter smell, and black after burning. Bead-like particles that can be crushed with your fingers.

The name of polyvinyl chloride fiber is difficult to burn. It is extinguished when it leaves the fire. The flame is yellow, and the lower end is green and white smoke. It emits pungent and pungent spicy and sour taste. After burning, the ash is dark brown and irregular lumps, and the fingers are not easy to be broken.

Five, spandex and fluorocarbon

Polyurethane, the name of spandex fiber, burns near the edge of the fire. When burning, the flame is blue. It leaves the fire and continues to melt, giving off a special irritating odor. After burning, the ash is soft and fluffy black ash. Fluorine fiber name polytetrafluoroethylene fiber, ISO organization called it fluorite fiber, near flame only melt, difficult to ignite, not burning, edge flame is blue-green carbonization, melting and decomposition, gas is toxic, the melt is hard round black Beads. Fluorinated fibers are commonly used in the textile industry to make high performance sewing threads.

There are relevant identification methods for these combustions to support your preliminary judgment of the material, and generally achieve accurate resolution.
