Abstract
A touch-and-close fastener part (32) includes a functional layer forming a backing surface and formed from a thread system with at least two line elements (12a-12d, 14a-14c) forming meshes (16a-16b″, 20a-20a″) and connected to one another. At least one further individual functional layer, formed and/or formable with connecting elements (30, 30″), is formed from a further thread system incorporated at least in individual sections into the thread system. The thread systems are connected to one another with the formation of passage sites (24a-24d) whose free cross-sectional area takes up more than 20% of the corresponding backing area.
Claims15
A touch-and-close fastener part, comprising:
- a first functional layer forming a backing surface formed from a first thread system having at least first and second line elements forming meshes and being connected to one another, said first thread system including a series arrangement of said first and second line elements that are adjacent to one another and that extend in a longitudinal direction, each of said first and second line elements forming a sequence of essentially identical meshes facing in a transverse direction without offsets relative to one another in the longitudinal direction, said meshes of at least one said first and second line elements extending at least one of through or around said meshes of an adjacent one of said first and second line elements, said meshes of adjacent ones of said first and second line elements having essentially same extensions in the longitudinal direction and in the transverse direction, said first thread system forming a pattern repeating at regular intervals in the longitudinal and transverse directions and being composed of identically arranged line elements;
- and
- a second individual functional layer having connecting elements formed from a second thread system incorporated at least in individual sections of said first thread system, said first and second thread systems being connected to one another and having passage openings therethrough, said passage openings having free-cross-sectional areas making up more than twenty percent of an area of said backing surface.
A method for producing a touch-and-close fastener part, comprising the steps of:
- forming a first functional layer forming a backing surface formed from a first thread system having at least first and second line elements forming meshes and being connected to one another, said thread system including a series arrangement of said first and second line elements that are adjacent to one another and extend in a longitudinal direction, each of said line elements forming a sequence of essentially identical meshes facing in a transverse direction without offsets relative to one another in the longitudinal direction, said meshes of at least one of said first and second line elements extending at least one of through or around said meshes of an adjacent one of said first and second line elements, said meshes of adjacent ones of said first and second line elements having essentially same extensions in the longitudinal direction and in the transverse direction, said first thread system forming a pattern repeating at regular intervals in the longitudinal and transverse directions and being composed of identically arranged line elements;
- and
- forming a second individual functional layer having connecting elements formed from a second thread system incorporated at least in individual sections of said first thread system, said first and second thread systems being connected to one another with passage openings therethrough, said passage openings having free-cross-sectional areas making up more than twenty percent of an area of said backing surface.
