PURPOSE:To obtain the title article suitable as paper, etc., by making conjugate yarn of plural resins having different melting points into web, integrating central part treated into hydrophilic nature with both end parts processed into hydrophobic nature and uniformly forming uneven parts at the central part. CONSTITUTION:Resins such as polyethylene terephthalate and polyethylene having preferably >=30 deg.C difference in melting point, for example, are made into conjugate yarn of sheath core type. The conjugate yarn is subjected to surface treatment with a hydrophilic surfactant such as metal salt of an alkyl sulfate and processed into a beltlike web, which is then sprayed with air and unevenness is formed on the surface to give central part. On the other hand, the conjugate yarn subjected to surface treatment with a hydrophobic surfactant such as silicone is made into beltlike webs, arranged at both sides of the central part, the parts are heat-treated and the low-melting component is thermally melted to give the objective nonwoven fabric 10 having the central parts 11 with protruded parts 11A and dented parts 11B and both the end parts 12. |
