3 Terms and Definitions
Terms and definitions defined in GB/T 3291.1, GB/T 3291.3, GB/T 4146 (all parts) apply to this document.
4 Product identification
4.1 The product specification is expressed by the nominal linear density and nominal length of the fiber. The unit of linear density is decitex (dtex); the unit of cut length is millimeter
(mm). For example. 1.33dtex×38mm, where 1.33dtex represents the nominal linear density and 38mm represents the nominal cutting length.
4.2 Product identification should include. product specifications, gloss, product name or batch number and other information, which can be effectively distinguished.
