T/NTTIC 032-2024 Filler with ultra-short fibers made of viscose

Scope

Scope: This standard specifies the terms and definitions, classification and labeling, technical requirements, test methods, inspection rules and marking, packaging, transportation, and storage requirements for viscose ultra-short fibers used for filling products. This standard applies to viscose ultra-short fibers with a nominal linear density of 0.8 dtex to 4.5 dtex used for filling, high-wet-modulus viscose ultra-short fibers (modal), and other types of viscose ultra-short fibers, which can be used as reference. Main technical content: Viscose short cut fibers for filling are made from dissolving pulp and produced by the viscose process. The cut length is 2mm to 20mm, with silicone and a moisture content of 11%. They are used for filling cellulose short fibers. Infant and toddler products are products worn or used by infants and toddlers under 36 months. Non-direct skin contact products are products that do not directly contact the skin or only have small parts in direct contact with human skin during wearing or use. Silicone fibers are processed with silicone finishing agents during post-treatment. The standard moisture content is 13%, and the product moisture content should be controlled between 8% and 11%. Products with an average value exceeding 14% or individual samples exceeding 15% shall not be shipped. Products with a moisture content below 8% shall only be shipped with the user's consent. The outgoing moisture content should be controlled around 11% to ensure that the filling material has comfortable warm-keeping performance.
