METHODS FOR MAKING FASTENERS

摘要

There is provided a fastener for engaging with a loop fabric, comprising a base having a front surface with a multiplicity of engaging projections. At least some of the engaging projections having a top surface end and an attached end. The at least some engaging projections top surface ends form an edge angle surrounding the projections. A mantle surface extending from the top surface end edge to the attached end. Generally at least one contour line of a side view of the mantle surface is convex. There is also provided a first method for forming a fastener, comprising: dispersing polymer particle into a contact release surface; transforming the polymer particles into an at least semiliquid state of a suitable viscosity for a time sufficient to transform into preform projections having contact edges; contacting and fixing the front surface of the base with the terminal ends of at least some of the preform projections; removing the base, thereby separating the preform projections, from the release surface; forming engaging projections projecting from the front surface of the base.
