Abstract
The present invention aims to provide a low tecmperture adhesive fiber, and nonwovens made of the fiber having high strength and soft feeling in spite of produced by heat treatment at a low temperature and a high-speed, and having strong adhesion with a hot melt adhesive, and an article having water absorption properties and being made of the nonwovens. A low-temperature adhesive fiber, characterized in that a textile oil of 0.1-2.0% by weight per fiber, which comprises the following surfactant composition of 5-15% by weight of the following component (A), 5-45 % by weight of the following component (B) and 40-90% by weight of the following component (C), is adhered to a conjugate fiber of polyolefins having a core component of polypropylene and a sheath component of a bipolymer or terpolymer of olefins principally containing propylene: PA1 (A) at least one alkali metal alkyl sulfonate, PA1 (B) at least one compound selected from polyol esters and fatty acid alkanol amides, PA1 (C) at least one compound selected from dibasic acid esters and polyethylene glycol esters.
