Identifying the material of the ribbon, a experienced man can identify the ribbon material by just touching it, the ribbon factory, the width and thickness. However, as a newcomer who has just stepped into the ribbon industry, it is obviously up to the accumulation of experience to reach such a level. The method of distinguishing the ribbon is: touch (feel of the ribbon), view its color, and burn.
Touch method, cotton ribbon, nylon or nylon material, the ribbon is soft, smooth, bright, bright, and light in material; the polypropylene (PP) ribbon feels hard, rough, and poor gloss; polyester material ribbon color Compared with rigid, but the color fastness is good, the specific gravity is heavier; polyester short silk (also known as polyester civilian silk, commonly known as polyester cotton) polyester polyester silk material has the same feel and cotton material, soft to the touch.
Combustion method: ignite it with fire, observe the state of the burning flame, smell the odor emitted after burning, and look at the remaining matter after burning, thereby judging the material of the ribbon. The warp and weft yarns of the two unknown types of ribbon are removed, and burned separately by a lighter. During the combustion process, some physical phenomena are observed 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.
It is easy to identify fibers by combustion, but blended products are not easy to judge. A yarn is drawn from each of the warp and weft directions (ie, the direction of the straight and the horizontal).
