T/NTTIC 030-2024 Filling lycra ultra-short fiber for filling

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 lyocell ultra-short fibers used for filling. This standard applies to lyocell ultra-short fibers with a nominal linear density of 0.8 dtex to 4.5 dtex used for filling. Other types of lyocell ultra-short fibers can be used as reference. Main technical content: Lyocell ultra-short fibers for filling are made from dissolving pulp and produced by spinning using the NMMO dissolving pulp method. The cut length is 2mm to 20mm, with silicon, and a moisture content of 11%. They are used as cellulose short fibers for filling. Infant and toddler products: Products for infants and toddlers under 36 months of age, used for wearing or use by infants and toddlers. Products without direct skin contact: Products that do not directly contact the skin or only have small parts in direct contact with the human skin during wearing or use. Silicon-treated fibers: During the finishing process, the fibers are treated with silicone finishing agents. 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 single samples exceeding 15% shall not be shipped out. Products with a moisture content below 8% shall only be shipped out with the consent of the user. The moisture content at the time of shipment should be controlled around 11% to ensure that the filling material has comfortable warm-keeping performance.
