FIELD: textile fabrics; paper.
SUBSTANCE: double-layer shaping meshes are woven according to general repeating weaving pattern that requires at least 8 sheds in loom. Transverse binding pairs of threads follow single combined line of motion, being woven with layer on paper side and layer on machine side with long internal displacement, at least, under four threads of layer on paper side between points of overlapping and interweaving in layer on machine side. Elements of pairs of threads are displaced to the side relative to each other along single combined line of motion. Mesh has complete filling of base after heat shrinkage by at least 100% of layer drainage area on paper side and layer on machine side - between 25% and 50%, and area of central plane drainage between 8% and 20%.
EFFECT: improved resistance to impact drainage in initial part of shaping section.
