Advances in polyolefin-based spunbond and binder fibres

Abstract This chapter discusses recent advances in soft and abrasion resistant spunbond fabrics made from polyethylene and polypropylene resins. Advances in polyethylene resin design via blending polyolefin plastomers for broadening bonding window and improving abrasion resistance of spunbond fabrics are described. Advances in propylene based spunbond fabrics using blends with propylene based plastomers and elastomers for improved softness and drapeability are also presented. Properties of bi-component spunbond fabrics made from polypropylene core and polyethylene sheath, combining tensile strength and spinnability of polypropylene, and softness and drapeability of polyethylene are discussed. Finally, properties of bonded air-laid pads produced from cellulose and bi-component binder fibres having polyester cores and a blend of polyethylene and MAH-g-HDPE in the sheaths are described.
