WAYS OF OBTAINING WAFFLE WEAVE FABRICS WITH DIFFERENTLY DIRECTED SQUARE DIAGONALLY SPACED RELIEF ELEMENTS Russian patent published in 2017 - IPC D03D23/00 

FIELD: textile, paper.

SUBSTANCE: way for producing waffle weave fabrics with differently directed square diagonally spaced relief elements, consists of forming parallel diagonals from single main floats, between which, one float from the diagonals, the main deckings of variable length are placed, which create repeating square relief elements from the main deckings with a slope. A second perpendicularly directed rectangular relief element is formed having a common or separate diagonal with the first element, for which a basic filling twill of the principal class with an odd rapport R_b is accepted, the number of m_m main deckings of maximum length in the rapport of the relief element within 2…R_b, one of the systems of threads as active, the second as passive; rapiers of wafer weave for the passive R_passive and active R_active and thread systems are determined; the vertex of the diagonals of the first relief element at the intersection R_b of the passive system thread (x₁=R_b) with the first thread of the active system (y₁=1) is put, a short diagonal of the relief element is obtained as a filling twill of the principal class with negative shift; long diagonals with the number of main deckings are placed perpendicularly to the short, equal to I_m=R_b+m_m-1; deviating one float from diagonals, the main deckings of variable length are placed, m_m of which have a maximum length equal to l_d=2R_b-5 of floats, obtaining in the rapport the first rectangular relief element; the coordinates of the vertex of the second relief element from the main deckings along the passive x₂ and by active y₂ systems of threads are determined; the first part of the second relief element from the main deckings of variable length is formed, varying from 1 to l_d with a pitch equal to two floats, then a second part of the second relief element is obtained, successively shifting m_m-1 of main deckings of l_d floats along the active system by one strand of the passive system to the left with the active system of weft threads or downwards with the active system of warp yarns, after which a third part of the main deckings element of variable length is formed, varying from l_d-2 to 1 in increments of two floats; then the resulting second relief element from the main deckings is framed by short main floats; retreating from the element one float; during the entire construction, the main floats that go beyond rapports on the active or passive filament systems are placed within their limits.

EFFECT: invention extends the range of waffle weave fabrics by a new arrangement of square relief elements from the maindeckings and floats of variable length.
