Scope

This part of GB/T 2910 specifies a method, using formic acid, to determine the
percentage of polyamide fiber, after removal of non-fibrous matter in textiles that are
made of binary mixtures of polyamide and cotton, viscose, cupro, modal, polyester,
polypropylene, chlorofiber, acrylic or glass fiber.
It is also applicable to mixtures with wool and animal hair. However, when the wool
content exceeds 25 %, the method described in GB/T 2910.4 should be used.

Summary	This standard specifies the method using formic acid determination to go after unless polyamide fiber and cotton fiber material, viscose fiber, copper ammonia fiber, modal fiber, polyester fiber, polypropylene fiber, chlorine fiber, polyacrylonitrile fiber or glass fiber and other two-component mixture of fiber content approach. This section also applies to a mixture of wool or other animal hair. But when the wool content exceeds 25%, should adopt the method GB/T 2910. 4 requirements.
