Standard Terminology for Cotton Fibers
SCOPE
1.1 This standard is the compilation of all terminology developed by Subcommittee D13.11 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, D7139 is also a tool for managing the Subcommittee’s 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 D123.
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
