Abstract (en)
[origin: EP1967621A2] The present invention relates to an abrasive backing and abrasive cloth and more particularly, to an abrasive backing including an upper weave layer and a lower weave layer which are comprised with warps (11-20) and wefts (a-j), and a binding yarn (70) which connects the upper weave layer and the lower weave layer, wherein the abrasive backing is woven by using the wefts of the upper weave layer (b,d,f,h,j) having a different thickness from those of the lower weave layer (a,c,e,g,i). When the weft of the upper weave layer and that of the lower weave layer have a different thickness, the upper weave layer and the lower weave layer may have uneven surfaces having different details and abrasive coat materials having different grain sizes.
