    • The present invention provides a method for forming preferably a unitary polymeric hook fastener comprising a flexible backing, and a multiplicity of spaced hook members projecting from the upper surface of the unitary backing wherein each hook member comprises a multiplicity of hook head elements projecting in substantially the same direction. The hook members each comprise a stem portion attached at one end to the backing, and a head portion at the end of the stem portion opposite the backing. The head portion can also extend from a side of a stem portion or be omitted entirely to form alternative projections which can be other forms than a hook member. The head portion preferably projects past the stem portion on at least one of two opposite sides. At least the hook head portions have two or more hook head elements on at least one of the two opposing sides of the stem. The hook head portions preferably have been heat treated so as to decrease the hook head thickness and thereby reducing or eliminating molecular orientation in at least the hook head in the machine direction.
    • 本发明提供了一种用于形成优选整体聚合物钩紧固件的方法,其包括柔性背衬和从整体式背衬的上表面突出的多个间隔开的钩构件,其中每个钩构件包括多个钩头元件, 同方向 钩构件各自包括在一端附接到背衬的杆部分,以及在杆部分的与背衬相对的端部处的头部。 头部还可以从杆部的侧面延伸,或者完全省略,以形成可以是钩构件以外的其它形式的替代突起。 头部优选地在两个相对侧中的至少一个上突出穿过杆部。 至少钩头部分在杆的两个相对侧中的至少一个上具有两个或更多个钩头元件。 钩头部分优选地经过热处理以减小钩头厚度,从而减少或消除至少钩头在机器方向上的分子取向。
