摘要： A composite spunbond nonwoven and a laminate using the same are provided. The composite spunbond nonwoven is formed of a composite fiber including a low melting point component and a high melting point component. The composite fiber is partially thermal compression bonded to each other, and thermal compression bonded portions have fine folded structures formed by repeating convex portions and concave portions in a CD (cross direction in nonwoven manufacturing). An average of distances between adjacent convex portions of the folded structures is in a range of 100 μm-400 μm. The composite spunbond nonwoven exhibits an elongation property by unfolding the fine folded structures. When the composite spunbond nonwoven is elongated by 5%, a CD strength is less than or equal to 0.1 N/5 cm width, and a MD/CD strength ratio is greater than or equal to 200. MD is longitudinal direction in nonwoven manufacturing.

摘要： A composite material as a sheet material is described, being relatively cheap, most useful as a raw material of a sanitary product or the like, such as underwear, dust-proof mask or dispensable paper diaper, etc., and good in processability, stretchability, gas-permeability, softness, and touch. The composite material is formed by laminating a stretchable layer and a conjugate spunbonded nonwoven fabric including conjugate fibers including a low-melting-point component and a high-melting-point component. The conjugate fibers are partially bonded to each other by thermocompression, wherein each bonded portion has fine folded structures including alternate hill and valley regions in the CD, and the distance between neighboring hills is 100-400 μm in average. The conjugate spunbonded nonwoven fabric exhibits stretchability through the spread of the fine folded structures, and has, at 5% elongation, a CD-strength of 0.1 N/5 cm or less and an MD/CD strength ratio of 200 or more.
