1、Designation: D 4466 02 (Reapproved 2007)Standard Terminology forMulticomponent Textile Fibers1This standard is issued under the fixed designation D 4466; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A
2、number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 Man-made polymers can be combined during manufac-ture, or natural polymers can be formed during growth, toproduce multicomponent fiber
3、s having special properties suchas cross dyeability, differential shrinkage, or bulk. This stan-dard contains terms which can be used to describe the physicalarrangement of components of such fibers. The schematicdiagram in Annex A1 provides a guide for interpreting theterminology used in describing
4、 two- and three-componentfibers, but is not intended to be limiting. Some examples ofusage are given in Annex A2, and a bibliography of relatedliterature is given in Appendix X1.1.2 For definitions of other textile terms, refer to Terminol-ogy D 123.2.

Terminologygeneric class, nas used with textile fibers, a grouping havingsimilar chemical compositions or specific chemical charac-teristics.DISCUSSIONIn the United States, the generic names and definitionsof man-made fibers, such as nylon, polyester, a

7、 same ordifferent chemical ponent, nas used with textile fiber polymers, a polymerwith distinguishable properties.bicomponent fiber, na fiber consisting of two polymerswhich are chemically different or physically different, orboth.biconstituent fiber, ndeprecated term. Use the preferredterm bicompon
8、ent bigeneric fiber.DISCUSSIONAs used in the Federal Trade Commissions “Rules andRegulations Under the Textile Fiber Products Identification Act,”“biconstituent fiber” is “essentially a physical combination or mixtureof two or more chemically distinct constituents or components com-bined at or prior
9、 to the time of extrusion, which if separately extruded,would fall within different .” generic classes. In the preferred ASTMterminology, a biconstituent fiber is a bicomponent bigeneric fiber. It isnot clear from the “Rules” whether a biconstituent fiber has asheath-core, bilateral, or matrix confi
