    摘要: The method of producing a spunbond nonwoven fabric promotes the bleed out of the additive, which has pleasant texture such as tactile feel and excellent flexibility. The spunbond nonwoven fabric is obtained by this method. Specifically, (1) the method of producing a spunbond nonwoven fabric includes annealing a spunbond nonwoven fabric formed by using a crystalline resin composition (I) containing a low crystalline olefin polymer (a) with an elastic modulus of 10 to 450 MPa in a content of 1 to 50% by mass, a high crystalline olefin polymer (b) with an elastic modulus of 500 to 2,000 MPa, the content of the component (b) being the rest, and an additive (c) in a content of 1 to 20,000 ppm by mass. Furthermore, (2) the method of producing a spunbond nonwoven fabric includes annealing a spunbond nonwoven fabric formed by using a core-sheath composite fiber containing a crystalline resin composition (I) as the sheath component; and a crystalline resin composition (II) as the core component containing a high crystalline olefin polymer (b′) with an elastic modulus of 500 to 2,000 MPa.

    摘要: The nonwoven fabric has excellent secondary fabrication properties, specially, low temperature heat-sealing properties. The textile product is formed by using the nonwoven fabric. More specifically, the nonwoven fabric includes one or more layers, wherein the nonwoven fabric made of one layer, or at least one layer of the nonwoven fabric composed of two layers, or at least one layer of the two outermost layers of the nonwoven fabric of multi-layer consisting of three or more layers is formed by using a crystalline resin composition containing 1 to 99% by mass of a low crystalline olefin polymer satisfying the following expression (a): ΔH≧6×(Tm−140° C.) wherein ΔH represents a melt endotherm, and Tm represents a melting point.
