3 Principle
The acrylic fiber was dissolved with dimethylformamide to leave the Modal fiber.
3.2 Milk fiber qualitative analysis method
The use of milk fiber and cotton, hemp, nylon, acrylic, polyester, polypropylene fiber to produce different odors; with silk, rabbit hair, wool and other eggs
White matter fibers have different solubility properties for chemical agents; and under microscope, different from the longitudinal and cross-sectional morphology of silk, rabbit hair, wool fibers,
It is proposed to identify milk fiber with cotton, hemp, silk, wool, nylon, acrylic, polyester by the combination of combustion and chemical dissolution or by the combination of combustion and microscope.
Polyester and polypropylene fibers.
