The present invention relates to an open network structu- re interlooped or interlaced from a multifilament hybrid yarn composed of at least 2 varieties A and B of fila- ments with or without cofilaments C, wherein said fila- ments A are textured and have a melting point above 180°C, preferably above 220°C, in particular above 250°C, said filaments B have a melting point below 220°C, preferably below 200°C, in particular below 180°C, the melting point of said filaments B being at least 20°C, preferably at least 40°C, in particular at least 80°C, below the melting point of said filaments A, and the weight ratio of said filaments A:B being within the range from 20:80 to 80:20, preferably from 40:60 to 60:40, and the multifilament hybrid yarn additionally containing up to 40% by weight of cofilaments C, said open network structure possessing good flatness and a capability to be rolled up and to be three-dimensionally deformed. The network structure of the present invention can be used in various ways for the decorative styling of complicatedly shaped surfaces, in particular for the production of light and vision protectors having a specifically predetermined light transmissivity and as an air-permeable insect resistor material.
