Identification methods of clothing material fiber

  •  Hand feeling and visual inspection

The method of hand sensing is to use hand touch and eye observation to judge the type of fiber by experience. This method is simple and does not require any instruments, but need rich experience. In the identification of clothing materials, besides touching and observing, the yarn can be removed from the edge of the fabric for identification.

Feeling and strength: Cotton, hemp feel hard, wool is very soft, silk, viscose fiber, nylon is moderate. When you break it with your hands, you feel that silk, hemp, cotton and synthetic fiber are strong; wool, viscose and acetate fibers are weaker.

Elongation: When stretching the length of the fiber, the elongation of cotton and hemp is smaller; The length of wool and acetate fiber is larger. However, the extension length of silk, viscose fiber and most synthetic fiber are moderate.

Length and uniformity: The length and uniformity of natural fiber are poor, and the length and uniformity of chemical fiber are better. Cotton fibers are slender, soft, and very short in length. The wool is long and curly, soft and elastic. Silk is long and slender and has a special luster. Hemp fibers are gelatinous and stiff.

Weight: Cotton, flax and viscose fiber is heavier than silk. Acrylic fiber and polypropylene fiber is lighter than silk. Wool, polyester, vinylon, acetate fiber are similar to silk.

  • Combustion method
  • Microscope observation

By using a microscope to observe the longitudinal shape and cross section of the fiber, or in combination with the dyeing method, natural fibers and the chemical fibers can be more accurately distinguished.
