Description of ASTM-D629 2015
1.1 These test methods cover procedures for the determination of the fiber blend composition of mixtures of the fibers listed in . Procedures for quantitative estimation of the amount of moisture and certain nonfibrous materials in textiles are also described, for use in the analysis of mixtures, but these are not the primary methods for the determination of moisture content for commercial weights.
1.2 These test methods cover procedures for the following fiber types:
1.2.1 Natural Fibers:
188.8.131.52 Cellulose-Base Fibers:
184.108.40.206 Protein-Base Fibers:
Animal hairs (other than wool)
1.2.2 Man-Made Fibers:
220.127.116.11 Cellulose-Base Fibers:
Rayon, viscose or cuprammonium
18.104.22.168 Synthetic-Base Fibers:
Nylon 6, Nylon 6-6, others
1.3 These test methods include the following sections and tables:
1.4 The analytical procedures described in the test methods are applicable to the fibers listed in . The test methods are not satisfactory for the separation of mixtures containing fibers that fall within the same generic class but differ somewhat, either physically or chemically, from each other. These test methods are not satisfactory for the determination of bicomponent fibers.
