Method of making a structured surface and article therefrom

摘要

A method of making a structured surface and a mechanical fastener precursor are disclosed. The method includes providing a thermoplastic backing with spaced-apart, upstanding posts with base portions attached to the thermoplastic backing and distal tips; deforming the distal tips to form caps on at least some of the spaced-apart, upstanding posts to provide capped posts, wherein at least some caps upon forming touch at least one adjacent cap; and separating the capped posts. Typically, the at least some caps upon forming are shaped at least partially by the at least one adjacent cap. The mechanical fastener precursor includes a thermoplastic backing and upstanding male fastening elements with bases attached to the thermoplastic backing and distal caps larger in area than the cross-sectional area of the bases, wherein the bases of the male fastening elements are spaced apart, wherein at least some of the distal caps touch at least one adjacent distal cap.

1. A method of making a structured surface, the method comprising:
providing a thermoplastic backing with spaced-apart, upstanding posts comprising base portions attached to the thermoplastic backing and distal tips; deforming the distal tips to form caps on at least some of the spaced-apart, upstanding posts to provide capped posts, wherein at least some caps touch at least one adjacent cap and are shaped at least partially by the at least one adjacent cap, and wherein the capped posts retain spaced-apart base portions; and separating the capped posts such that the at least some caps no longer touch the at least one adjacent cap.
