GB/T 13835.4-2009 "Test method for rabbit hair - Part 4: Moisture regain - Drying oven method"

This standard specifies the test method for determining the moisture regain of rabbit hair fibers by oven method, which is applicable to the in-box heat weighing method. The method requires that the specimen be dried at the specified temperature and humidity until the mass is constant, and the moisture regain rate is determined by calculating the moisture content lost by the specimen. This standard is suitable for evaluating the moisture content of rabbit hair fibers and provides a basis for the production and quality control of Spinning & weaving products.
