3 Terms and Definitions
The terms and definitions defined in GB/T 4146 (all parts) apply to this document.
4 Product identification
4.1 The product specification is expressed by the nominal linear density of the fiber and the nominal cut length, the unit of linear density is decitex (dtex); the unit of cut length is mm
(mm). For example. 1.67dtex×38mm, where 1.67dtex represents the nominal linear density and 38mm represents the nominal cutting length.
4.2 The product identification should contain information such as product specification, product name, batch number, etc., which can be effectively distinguished.
5 Technical Requirements
5.1 Product classification
The products are divided into two grades. high-quality products and qualified products.
