METHOD OF OBTAINING TISSUE WITH LONGITUDINAL SHADOW WEAVE Russian patent published in 2013 - IPC D03D23/00 

FIELD: textiles, paper.

SUBSTANCE: method of obtaining tissue with longitudinal shadow weaves with volume light stripes is claimed. The method consists in gradual transition along the weft from the basic weaves of the main class with a lighter weft effect to the interlacing of to the main class with a darker main effect or vice versa. This is due to the gradual increase of single interlacing in stages made along the warp up or along the weft to the right. In the rapport the weaves of several longitudinal volume light stripes of different width are formed. The number k₍₎ of stripes in the rapport of shadow weave is taken, a kind of initial light effects in the stripes - from light to shadow or from shadow to light, depending on which the basic weave with the rapport R_b is taken. The number of stages of the transition from light to shadow (or from shadow to light) is found in each longitudinal light stripe equal to R_b-1. The k₍₎ of sequences of repetitions of the rapports in the j-th stage of the i-th longitudinal light stripe n_ij is taken. The rapport R₍₎ of weave on the warp is determined as the amount of threads in the first longitudinal stripes, which are in turn the sum of the warp threads in the direct R_d.i and reverse R_rev.i light transitions. The rapport R_w of the weft is defined as equal to the rapport R_b of the basic weave on certain formulas.

EFFECT: diversification of tissues by obtaining on its surface of the visual effect of several longitudinal volume light strips different in width.
