Spun Bonded Nonwoven Fabric And Sheath Core Type Composite Fiber
Abstract: The present invention addresses the problem of providing a spun-bonded nonwoven fabric which has excellent flexibility, excellent texture, uniform formation, strength that is sufficient for practical use, and excellent productivity. The present invention provides a spun-bonded nonwoven fabric which is formed of a sheath-core type composite fiber that is mainly composed of a polyethylene resin, and which has a fused part and a non-fused part. With respect to this spun-bonded nonwoven fabric, the ratio of the orientation parameter Ofs of the sheath component of the sheath-core type composite fiber in the non-fused part to the orientation parameter Ofc of the core component of the sheath-core type composite fiber in the non-fused part, namely Ofs/Ofc is 0.10 to 0.90.
