METHOD OF OBTAINING FABRIC DICE CHECKS Russian patent published in 2018 - IPC D03D23/00 

FIELD: textile and paper.

SUBSTANCE: invention relates to the production of textile materials and refers the webbing fabrics manufacturing belonging to the small-mesh class, produced on looms, equipped with a carriage shedding machine. In the claimed method, on the surface of the fabric obtaining a visual effect of the volumetric diagonally symmetric second-order surfaces by changing the of the individual square checkers dimensions with their unchanged number in the rapport of the initial dice check on both yarn systems. For this, taking a basic dice check, each checker S_ch size and the number of their pairs n_ch in the weave rapport, the threads of one system are lighter, the threads of the other one are more dark; defining the weave rapport: R_o=R_y=R=2S_ch⋅n_ch; after finding of the checkers [n] color change coordinates, a matrix A(R, R) is obtained for both systems of threads, filled with equal to 0 or 1 elements; on the rapport plane, building the original checker pattern model with equilateral checkers, taking into account that the equal to zero matrix element value corresponds to the drawing point coloring into white, and equal to one is into black color; forming the field in coordinates: Sequence numbers of threads (from 1 to R) – Image deformation level (from 0 to 1) with movable markers set along the horizontal midline corresponding to the absence of deformation; moving the markers vertically, performing the fabric checker pattern deformation simulation, taking into account that the marker location above the middle line corresponds to the reduction in the checkers size, below the midline is to increasing; setting the form of the approximating curve for the checkers size changing along the threads of both systems; forming a new matrix A_def.(R, R), by which elements values the new checker pattern model is obtained; building rapport off the deformed dice check.

EFFECT: result is an expansion of the fabrics range by obtaining a visual effect of volumetric diagonally symmetric surfaces of the second order on their surface.
