2.78dtex*51mm Loi 38%~42% Raw Pink FR Flame Retardant Modacrylic Fibre
1. Introduce
Acrylic fiber is a synthetic fiber that closely resembles wool in its character. According to the definition of the ISO (International Standards Organization) and BISFA (International Synthetic Fiber Standardization Office), fibers which contain a minimum of 85% acrylonitrile in their chemical structure are called "Acrylic Fibers".
Acrylic fiber is composed of acrylonitrile and a comonomer. The comonomer is added to improve dyeability and the textile processability of the acrylic fiber. Acrylic fiber is produced with two different systems: wet spinning and dry spinning. Acrylic fiber can be supplied as producer-dyed either by pigmentation of the dope or with jel dyeing systems. It can be used 100% alone, or in blends with other natural and synthetic fibers.
Generally, LOi ＞ 28% is called flame retardant acylic fiber, while LOi is in the range of 38%~42%. The excellent flame retardant performance under heating conditions is called modacrylic fiber.
