METHOD OF MANUFACTURING MULTILAYER CONTOUR-PROFILED TISSUE Russian patent published in 2012 - IPC D03D11/00 

FIELD: textiles and paper.

SUBSTANCE: method of manufacturing a multilayer contour-profiled hollow tissue includes weaving of weft threads and several systems of warp threads. One of which is used to create folds with upper and lower flaps, the others for binding the folds on flaps and stitching the folds at different levels of the thickness of the tissue. On transition of weft threads from the lower fabric to the upper fabric they are weaved with the warp threads of the corresponding layers preserving the weaving pattern in the fabrics; reaching-in of warp threads in reed with a decrease in the number of threads in the edge areas of fabrics; a stepped entering line of the machine; one-part centre harness ties in harness board of the weaving loom, and when repeating ties of the right half of the harness board each subsequent even short row of lifting string is swapped with each previous even short row of lifting string, in the transition of the weft threads from the upper fabric of the multilayer contour-profiled hollow tissue into the lower fabric the weft threads are fixed in the zone of relative stitch using selvage motion, and in the weaving pattern, when fixing the upper flaps of the folds of the multilayer contour-profiled hollow tissue of one of the main systems, continuous serge diagonal lines are formed both on the outer surfaces, and at a given depth of the upper and lower fabrics of the multilayer contour-profiled hollow tissue providing the effect of spiral volumetric guides on the surface of the multilayer contour-profiled hollow tissue.

EFFECT: elimination of deformation.
