Scope

Scope: This document specifies the terms and definitions, classification and labeling, technical requirements, test methods, inspection rules, marking, packaging, transportation, and storage for cationic regenerated cellulose staple fibers. This document applies to cationic viscose staple fibers, modal staple fibers, and lyocell staple fibers with a nominal linear density range of 0.9dtex to 2.22dtex. Main technical content: - Projects: Excellent, First-Class, and Qualified Products - Dry breaking strength (cN/dtex) ≥ 2.0 for cationic viscose staple fibers, ≥ 1.8 for cationic modal staple fibers, and ≥ 2.5 for cationic lyocell staple fibers. - Dyeability/grade ≥ 43-4. - Item No. Projects Cationic Viscose Staple Fibers Cationic Modal Staple Fibers Cationic Lyocell Staple Fibers 1 Wet modulus [(cN/dtex)/5%] ≥ ——0.440.752 Wet breaking strength (cN/dtex) ≥ 1.051.62.83 Dry breaking elongation (%) M1a ± 2.0 M1 ± 2.0 M1 ± 1.54 Dry breaking strength variation coefficient (CV) (%) ≤ 18.018.015.05 Linear density deviation rate (%) ± 4.0 ± 4.0 ± 4.0 Length deviation rate (%) ± 6.0 ± 6.0 ± 6.0 Superlong fiber rate (%) ≤ 0.51.00.58 Extra-long fiber (mg/100g) ≤ 4.04.04.09 Residual sulfur content (mg/100g) ≤ 12.012.0 ——10 Defect content (mg/100g) ≤ 4.04.05.011 Oil stains and yellow fibers (mg/100g) None None None 12 Whiteness (% M2b ± 3.0 M2 ± 2.0 M2 ± 3.0 a M1 is the center value of dry breaking elongation. The dry breaking elongation of cationic viscose staple fibers shall not be less than 19%, and that of cationic modal staple fibers shall be controlled within 13% to 17%. The dry breaking elongation of cationic lyocell staple fibers shall not be less than 12%. b M2 is the center value of whiteness, which shall not be less than 60%. The specific value shall be determined through consultation between the supplier and the buyer.
