Laser weldable hook-and-loop fastener

Abstract

This laser weldable hook-and-loop fastener includes a laser-light-transmissive male molded hook-and-loop fastener (A) and a laser light absorption layer (B) that comprises a thermoplastic resin and that is integrated with the reverse of the male molded hook-and-loop fastener (A), wherein: the male molded hook-and-loop fastener (A) has a substrate and a large number of male engagement elements standing upright from the obverse of the substrate; the male engagement elements and the substrate are formed from the same resin selected from polyester elastomers and polyamides; the male engagement elements are arrayed in a row; and the absorption rate of infrared light with a wavelength of 980 nm is not less than 85% for the laser light absorption layer (B). The laser weldable hook-and-loop fastener is suitable for performing welding, by using laser light, on the reverse of an automobile interior material such as a ceiling material and a floor material.

Description

technical field [0001] The present invention relates to a laser weldable molded surface fixing material suitable for fixing automotive interior parts such as ceiling materials and floor materials to a vehicle body. On the back side of the male shaped surface holder, the integrated laser absorbing layer is melted by laser. The convex molding surface fastener can be firmly welded to the rear surface of an automotive interior part without damage to the shape or performance of the convex molding surface fastener due to the heat of the laser absorbing layer and via the melted laser absorbing layer. Background technique [0002] In the past, as one of the mounting members for mounting other objects on the surface of the object, a male surface fixing member having a hook-shaped engaging part was used to fix the surface of any one of the two objects, and a loop was used. A method in which the female surface fixing part of the type engaging part is fixed on the other surface, and th...

Problems solved by technology

[0018] However, in general, fasteners refer to sliding fasteners in many cases, and there are almost no cases of surface fasteners.

In addition, since there is no description about the surface fastener in Patent Document 5, it is impossible to think of the convex-shaped surface fastener as the object of the present invention from the description of the surface fastener alone.
