Bi-component compound fiber (for heat-sealing)

Bi-component compound fiber is a compound-spun fiber made from PE and PP, or PE and PET sheath-core. A low-melting-point polymer (PE) acts as the sheath and a high-melting-point polymer (PP or PET) as a core in the making of heat-sealing non-woven fabric. Heat-sealing requires no chemical adhesive due to the low fusion point of the low-melting-point fiber, allowing for an eco-friendly and biologically safe product.
