FIELD: textile and paper.SUBSTANCE: invention relates to methods to assess drapability of leather and fur semi-finished products. Method involves fixation of sample on holder with possibility of vertical movement, determination of parameters of projections of sample, total drapability, drapability in lengthwise and crosswise directions. At that, test sample is taken skin without point of sample, on which is determined by longitudinal and transverse direction. Method involves putting sample on holder; determination of parameters of projection drapability, which is estimated drapability coefficient (Dlc), as well as drapability in lengthwise and crosswise directions, which is estimated coefficients (Dlc.γ and Dlc.β) calculated by formulas: Dlc.γ=((180-γ)/180)*100, Dlc.β=((180-β)/180)*100, Dlc=(Dlc.γ+Dlc.β)/2; where γ is angle, sides of which are projection of sides of sample in longitudinal direction, β is angle sides of which are projection of sides of specimen in crosswise direction.EFFECT: this method allows reducing material consumption and increases accuracy and information value of obtained characteristics.1 cl, 5 dwg, 1 tbl, 1 ex |
