FZ/T 52026-2012 Flame-retardant recycled polyester staple fiber
Basic Information
Scope
This standard specifies the classification and labeling, technical requirements, test methods, inspection rules, and marking, packaging, transportation, and storage requirements for recycled flame-retardant polyester staple fibers.
This standard applies to the quality evaluation of recycled flame-retardant polyester staple fibers produced by melt-spun spinning with recycled polyester (PET) as the raw material and flame-retardant masterbatch added, with a linear density of 1.56 dtex to 6.00 dtex for yarn and a linear density of 2.78 dtex to 27.8 dtex for filling. Other types of recycled flame-retardant polyester staple fibers, except for those with surface finishing (spraying or dipping), can be implemented in accordance with this standard.
