Sensory identification is the most convenient identification method based on the appearance characteristics and feel of various raw materials or fabrics. The sensory characteristics of commonly used fibers are as follows:
Cotton Fiber: Cotton fiber is staple fiber. Fibers vary in length. Fibers are thin and soft.
Linen Fiber: Linen fiber is staple fiber. Rough, hard and cool. It is difficult to distinguish individual fibers. Most of them are yellow-gray.
Wool Fiber: Wool fiber is short fiber. But thicker and longer than cotton fibers. The individual fibers are naturally curled along their length and are creamy white in color. It feels smooth, rich and elastic.
Silk Fiber: Silk fiber is filament fiber. The white is slightly yellowish, with a soft luster. The fibers are thin and long, with a length of hundreds of meters to thousands of meters.
Viscose Rayon: It is divided into two types: bright fiber and dull fiber. The color is white. Feels like cotton fibers. The biggest difference between the two is the wet strength. The wet strength of viscose is much lower than the dry strength. Wet the yarn with a drop of water and tug at the ends of the yarn. Viscose will break where it gets wet.
Polyester: Polyester is filament fiber. Cool and quite. Strong and flexible. Not easily deformed.
Nylon: Nylon is filament fiber. Has a waxy finish. Strong and flexible. It is easier to deform than polyester.
Sensory identification is simple but requires rich practical experience. And it can only be used to analysis some commonly used fibers. Therefore, there are certain limitations.
