Made from a variety of yarns made of narrow fabric or tubular fabric. Wide variety of webbing materials are widely used in apparel, shoe materials, luggage, industry, agriculture, military supplies, transportation and other industrial sectors. In the 30's, the ribbons were all hand-woven fabrics with beautiful pictures. The raw materials were cotton thread and twine. After the founding of New China, the raw materials for webbing were gradually developed into nylon, vinylon, polyester, polypropylene, spandex, viscose, etc., forming woven, knitted, and knitted three kinds of process technologies. The fabric structure includes plain weave, twill weave, satin weave, jacquard, Double, multi-layer, tubular, and joint organizations. A number of warp and weft yarns of two types of ribbons of unknown type were removed and burned separately with a lighter. During the burning process, some physical phenomena were observed to determine the raw materials of warp and weft yarns. When burning, observe the flame, the melting condition, the odor emitted, and the condition of the burned ash. Nylon webbing: Near flame is melted and fused, dripping and bubbling without direct continuation like celery taste hard, round, light, brown to gray, beaded
Polyester webbing: near flame that melts and melts, drips and foams? Can continue burning, a small number of cigarettes? Very weak sweet hard round, black or light brown, cotton fiber and hemp fiber?

Both the cotton fiber and the hemp fiber are flammable immediately after being fired, burning rapidly, and the flame is yellow and blue smoke. The difference between the burning odor and the burning ash is that the cotton burns a paper smell and the hemp burns out the ash odor; after burning, the cotton has very little powder ash, black or gray, and the hemp produces a small amount of grayish white powder ash. Second, nylon and polyester
Nylon (Polyamide) scientific name polyamide fiber, near the flame that quickly curled into a white gel, melting in the flame dripping and blistering, there is no flame when burning, difficult to continue to burn away from the flame, emitting celery taste, after cooling The light brown melt is not easy to grind. Polyester scientific name of polyester fiber, easy to ignite, near the flame that is melted down, burning side while melting black smoke, a yellow flame, emitting an aromatic smell, burning ash after the dark brown hard block, with your fingers can smash. Three ways to identify the good and bad of the webbing
Chromatic aberration test: This can be observed with the naked eye, see its color, texture with needles, can not be messy, it should be a very pure color. Burrs: Usually the burrs of some yarns. This can also be observed with the naked eye. The two sides of the webbing and the seams can not have serious hair bulbs and hairs. Needle skipping: This can be observed with the naked eye, using various yarns as raw materials to make a narrow-width fabric or tubular fabric.

The webbing cannot have jumpers. The quality of the webbing must also be related to the specifications of the webbing. The standard specification is the best embodiment of webbing quality.
Weaving machine with webbing. In the 30's, wooden looms and iron wooden looms were hand-drawn. In the early 1960s, the 1511 looms were converted into webbing machines and are still widely used. Because the width of the tape is small, the weaving method is not the same. There are single, double, dozens, single and double layers.
There can't be a jumper. The quality of the webbing must also be related to the specifications of the webbing. The standard specification is the best embodiment of webbing quality.
