Beschreibung
Zusammenfassung:	The present invention relates to a laser weldable hook-and-loop fastener containing a laser light transmitting male-type molded hook-and-loop fastener (A) and a laser light absorbing layer (B) formed of a thermoplastic resin, which is integrated on the back surface of the male-type molded hook-and-loop fastener (A), wherein the male-type molded hook-and-loop fastener (A) has a base plate and a large number of male-type engaging elements rising from the surface of the base plate, the male-type engaging elements and the base plate are formed of the same resin selected from a polyester elastomer and a polyamide, the male-type engaging elements are arranged in a row, and the laser light absorbing layer (B) has an infrared absorptance of 85% or more at a wavelength of 980 nm. The laser-weldable hook-and-loop fastener of the present invention is suitable for welding to the back surface of an interior material for automobiles such as a ceiling material or a floor material by using a laser light.
