SUBSTANCE: in the claimed method on the surface of the fabric the visual effect of volume combs is obtained due to formation in the repeat of the weave of transverse and longitudinal light bands by gradual increasing and then decreasing the number of warp (or weft) overlaps without repetition, with uniform or non-uniform repetition of repeats of the basic weave in steps of light transitions. Voluminosity of the combs is produced due to the presence of the reverse light transition on both systems of filaments.

SUBSTANCE: method of obtaining tissues of longitudinal zigzag shadow weaves lies in the gradual transition along the weft, or along the warp from the basic weaves of the main class with a lighter main effect to weaves of the main class with a darker main effect, or vice versa. This is due to the gradual increase in single interlacing in steps, performed along the warp upwards or along the weft to the right, according to the invention, the longitudinal zigzag weaving is formed on the base of the initial shadow weave carrying positive or negative rapport shift of the initial shadow weave on the value of one step. In each tooth the direction of the slope of light stripes is changed to the opposite after a predetermined number Kw of warp yarns. Fullness of stripes and the teeth is obtained by forming the inverse light transition of the initial shadow weave with a number of steps equal to the number of steps of the direct light transition, to its mirror image. The pattern consists of the teeth located on the ascending or descending line formed by the sloping volumetric light stripes that change their width and direction on the width of the fabric.

EFFECT: diversification of fabric by obtaining on its surface of render effect of volumetric longitudinal zigzag pattern.

SUBSTANCE: in rapport of weaving the sloping volume light stripes are formed, extending in different directions, for which previously the original shadow weave is produced, taking one of the threads systems as active, and the second as passive. The original shadow weave is formed along the passive threads system, gradually passing from basic weaves of the main class with a lighter weft effect to weaves of the main class with a darker basic effect, or vice versa, due to gradual increase in the single interlacing in steps, made along the warp up or along the weft to the right; copying in inversed manner the direct light transition, the reverse light transition is obtained; the initial shadow weave is shifted along the threads of the passive system in a positive or negative side by the amount of shift, which is equal to the rapport of the basic weave. Then a break of sloping light stripes is carried out on warp and weft after Kwarp of warp and Kweft of weft threads.

EFFECT: diversification of tissues by obtaining on their surface of the effect of visualisation of volume lozenges formed by sloping light stripes extending in different directions.

SUBSTANCE: method of obtaining tissue with transverse shadow weave is claimed. The method consists in the gradual transition along the warp from the basic weave of the main class with a lighter weft effect to the weave of the main class with a darker warp effect and back or vice versa. This is due to the gradual increase in the single interlacing in stages carried out along the warp up or along the weft to the right. The weave of several transverse volume light stripes of different widths is formed in rapport, for which a number 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 Rb is taken: weft or warp.

EFFECT: diversification of tissue by obtaining on its surface of the effect of visualisation of several transverse volume light strips different in width.

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 Rb 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 Rb-1. The k() of sequences of repetitions of the rapports in the j-th stage of the i-th longitudinal light stripe nij 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 Rd.i and reverse Rrev.i light transitions. The rapport Rw of the weft is defined as equal to the rapport Rb 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.

SUBSTANCE: method of obtaining tissues of transverse broken shadow weaves is declared. It consists in the gradual transition along the weft or along the warp from the basic weaves of the main class with a lighter weft effect to the weaves of the main class with a darker warp effect, or vice versa. This is due to the gradual increase in the single overlaps in steps made along the warp up or along the weft to the right according to the invention, the direction of the inclination of light stripes is changed to the contrary, after the specified number of Kw weft threads. The transverse broken weave is formed based on the original shadow weave, carrying out a positive or a negative shift of the rapport of the original shadow weave on the value of one step. The voluminosity of transverse broken light strips changing their direction along the length of fabric, is obtained by forming the reverse light transition of the original shadow weave, with a number of steps equal to the number of steps of the forward light transition, by its mirror image.

EFFECT: diversification of tissues by obtaining on their surface of the effect of visualisation of volumetric transverse broken lighting strips, changing their direction along the length of tissue in the method of obtaining the tissues of transverse broken shadow weaves.

SUBSTANCE: in rapport of the weave the volumetric light strips inclined to the right or left are formed, for which previously the original shadow weave is produced, taking one of the systems of threads as the active, and the second - as the passive. Original shadow weave is formed along the passive system of threads with the rapport Ractive on the active system, equal to the amount of threads of the active system in the forward Rfor and reverse Rrev light transitions, and the rapport Rpassive on the passive system of threads, equal to rapport of the basic weave: gradually moving along the weft or along the warp of the basic weaves of the main class with a lighter weft effect to the weaves of the main class with a darker warp effect, or vice versa, due to the gradual increase in the single overlaps in steps, made along the warp up or along the weft to the right, copying mirror-like the direct light transition, the reverse light transition is obtained. The original shadow weave is then shifted along the threads of the passive system to the positive or negative side on the shift amount equal to the rapport of the basic weave.
