Abstract

1. Touch-and-Close Fastener Part and Method for Producing a Touch-and-Close Fastener Part

2. A touch-and-close fastener part (32) comprising:

• • a functional layer which fixes a backing surface, formed from a thread system with at least two line elements (12a-12d, 14a-14c) which form meshes (16a-16b″, 20a-20a″) and which are connected to one another,
  • at least one further individual functional layer which has formed and/or formable connecting elements (30, 30″), which layer is formed from a further thread system which is incorporated at least in individual sections into the thread system,
  • is characterized in that 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.
