A polypropylene based nonwoven fabric is excellent in surface appearance and stretch properties and exhibits a small residual strain and excellent adhesiveness to polyolefins. The nonwoven fabric is obtained by forming a polypropylene resin composition comprising 1 to 40 weight parts of (i) an isotactic polypropylene, and 60 to 99 weight parts of (ii) a propylene/ethylene/α-olefin copolymer obtained by copolymerizing 45 to 89 mole % of propylene, 10 to 25 mole % of ethylene and the balance of α-olefin having 4 to 20 carbon atoms (with the proviso that the copolymerized amount of the α-olefin having 4 to 20 carbon atoms does not exceed 30 mole %), characterized by a small residual strain after stretching at a stretch ratio of 150%. The nonwoven fabric can be effectively used as sanitary materials or the like by virtue of its characteristics including stretch properties.

A nonwoven fabric laminate possesses excellent elasticity, softness, water resistance, fuzz resistance and curl resistance, and has less stickiness. The nonwoven fabric laminate includes at least one meltblown nonwoven fabric layer and mixed-fiber spunbonded nonwoven fabric layers on both surfaces of the at least one meltblown nonwoven fabric layer, the mixed-fiber spunbonded nonwoven fabric layers each comprising mixed fibers including 10 to 90 wt % of continuous fibers of a thermoplastic elastomer (A) and 90 to 10 wt % of continuous fibers of a thermoplastic resin (B) other than the thermoplastic elastomer (A) ((A)+(B)=100 wt %).

IPC Classes  ?

  • B32B 5/26 - Layered products characterised by the non-homogeneity or physical structure of a layer characterised by the presence of two or more layers which comprise fibres, filaments, granules, or powder, or are foamed or specifically porous one layer being a fibrous or filamentary layer another layer also being fibrous or filamentary
  • D04H 1/00 - Non-woven fabrics formed wholly or mainly of staple fibres or like relatively short fibres
  • D04H 1/56 - Non-woven fabrics formed wholly or mainly of staple fibres or like relatively short fibres from fleeces or layers composed of fibres without existing or potential cohesive properties by welding together the fibres, e.g. by partially melting or dissolving in association with fibre formation, e.g. immediately following extrusion of staple fibres

Abstract

A nonwoven web is provided. The nonwoven web contains a side-by-side composite fiber having crimps. The composite fiber contains first and second propylene polymers. The nonwoven web contains a bonded portion that contains a bonding pattern containing zigzag unit patterns. The zigzag unit patterns are continuous and substantially parallel with a first direction and are disposed in a second direction at predetermined intervals. A triangle formed by adjacent three contact points of a first diagonal line and a second diagonal line of the unit pattern contains a part of the unit pattern that is adjacent to the triangle in the second direction.
