wherein Y is the dye amount of the interweaving points, owf J For the dye usage amount ρ of the warp yarn where the interweaving point is located J Is the warp density of the woven fabric, S J Owf for warp yarn branch of the color W For the dye usage, ρ, of the weft yarn where the interweaving point is located W Is the weft density of the woven fabric, S W Weft yarn of the colorYarn supporting;
the method for judging the color depth of the woven fabric according to the quantity ratio of each interweaving point and the dye consumption comprises the following steps:
classifying various interleaving points according to dark interleaving points, medium interleaving points and light interleaving points;
and counting the quantity proportion of the deep color interweaving points, the medium color interweaving points and the light color interweaving points in the woven fabric.
5. The method for detecting woven fabric according to claim 4, wherein the woven fabric is composed of a plurality of cyclic pattern units, and the color depth of the whole woven fabric is determined by obtaining the number ratio of each interweaving point in one cyclic pattern unit and the dye consumption.
6. The method for detecting woven fabric according to claim 4, wherein the number of the interlacing points is calculated according to formula (one),
P x =(M Jx /M j Total )×(M Wx /M W total ) X 100% formula (one),
in formula (one), P x For the number of the interweaving points of a certain class, M Jx For the number of warp yarns corresponding to the interweaving points, M J Total M is the number of all warp yarns Wx For the number of weft yarns corresponding to the interweaving points, M W total The number of all weft yarns.
7. The method according to claim 4, wherein the interlacing points with a dye amount of 1% or less are classified as light interlacing points, the interlacing points with a dye amount of 1% or more and 3% or less are classified as medium-color interlacing points, and the interlacing points with a dye amount of 3% or more are classified as dark interlacing points.
8. The method according to claim 7, wherein when the number ratio of one or more of the dark color interlacing points, the medium color interlacing points, and the light color interlacing points in the woven fabric reaches a prescribed value, the woven fabric is detected using the corresponding one or more detection criteria.
9. The method of detecting woven fabric according to claim 8, wherein the predetermined value is 10%.
