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

FIELD: textile, paper.

SUBSTANCE: method for producing waffle weave fabrics with rectangular diagonally arranged relief elements, consisting in the formation of parallel diagonals from single main overlaps, between which, one diagonal overlapping from the diagonals, the base decks of variable length are staggered, which create repeating rectangular relief elements from the main deck with a slope. Repeating rectangular relief elements with a tilt to the right or to the left, which in the first instance take the basic weft twill with the repeating pattern R_b Number m_o main decking maximum length in rapport relief element within 2…2R_b, One of the threads in the system as active and the second as passive; with the specified number of additional threads of active and passive systems N_active and N_passove in the repeat of the relief element. In this case: is N_active - any integer within -2…+2, N_passive. are taken equal to -1 or +1 with the odd m_o, equal to -2, 0 or +2 if the number is m_o; the repeating pattern of the waffle weave is defined as R_Passive passive system threads; shift S_Active is specified as peaks of the relief element active system threads within -R_passive/2…+R_passive/2 as an even number, including zero, with an even number of strands N_active+R_Passive or as an odd number, non-zero with the odd number of strands N_active+ N_passive; Find the number of repetitions of the relief element n repeat, repeat the element R_e and repeat the waffle weave R Active according to the active system of threads; Place the first vertex of a rectangular diagonally placed relief element at the intersection of the first thread of the active system with R_b the thread of the passive system; The short diagonals of the relief element are obtained as the weft twill of the main class with negative shift and the long diagonals with the number of principal overlaps equal to l_o=R_b+M_o-1; Repeat the pattern of the original rectangular diagonally positioned relief element from the warp effect of variable length, m_o of which have a maximum length equal to l_n=2R_b-5 main overlaps; The subsequent repetitions of the relief elements are obtained by copying the original relief element, each time with the vertex of the rectangular diagonally disposed relief element shifted along the passive thread system to R_e threads of the active system and along the active yarn system on ±S_active. threads of the passive system; When non-closed rectangular diagonally arranged elements are placed on the weft effect, additional diagonals are set up between the relief elements of the warp effect along the passive or active systems of the filaments; the location of additional diagonals is taken from the condition of obtaining the maximum possible area of relief elements from the weft deck; To obtain waffle interlaces with rectangular relief elements with the slope of the elements from the basic decking to the left, the pattern of the weave is mirrored by the active system of threads.

EFFECT: invention extends the range of waffle fabrics by changing the area of rectangular diagonally placed raised elements, of varying number and location in the repeat pattern.
