| description | 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. |
