Sheath(PP) / Core(PET) Low Melting Fiber
OPT, which is produced by bicomponent spinning technology with polyprophylene(Sheath) and polyester(Core), has more adhesive characteristics than PP fiber and used for multifunctional materials to get hydrophilic or hydrophobic properties and high lofted soft non-woven.
Good Heat Sealing Property
The low melting point PP in sheath part give the fiber good heat sealing property.
Excellent Soft Touch with High Loft
OPT is softer than normal polyester LMF because of Olefin(PP)`s low modulus.
Safe for Human Body
Using OPT, Resins toxic to human body are not needed.
As occasion demands, hydrophilic or hydrophobic properties can be selected and provided.
Better Chemical Resistance
OPT has better chemical resistance than regular polyester.
