Standard Terminology for Cotton Fibers

SCOPE
1.1 This standard is the compilation of all terminology developed by Subcommittee D-13.11 on Cotton Fibers.
1.2 This terminology is unique to the Cotton Fibers industry. Meanings of the same terms used outside the industry can be found in other compilations or in dictionaries of general usage.
1.3 In addition to being a specialized dictionary, D 7139 is also a tool for managing the Subcommittees terminology. This includes finding, eliminating, and preventing redundancies, that is, where two or more terms relating to the same concept are defined in different words.
1.4 Terms listed are under the jurisdiction of Subcommittee D13.11.
1.5 For definitions of other textile terms see Terminology D 123.
