Description

  The present invention relates to a bias fabric manufacturing apparatus, and more particularly, to a seamless bias fabric manufacturing apparatus using a tubular fabric that cuts a fabric woven in a tubular shape so that the bias fabric can be manufactured. It is about.

  FIG. 1 is a diagram showing a general fabric, and FIG. 2 is a diagram showing a bias fabric. A general woven fabric (C; see FIG. 1) has a planar shape by repeated intersection of warp (Wp) and weft (Wt). Simply woven fabric (C) is a warp (Wp) and a weft. (Wt) means a plain weave fabric intersected at an intersecting angle (θ1) of 90 degrees, that is, at a perpendicular angle of 90 degrees.

  On the other hand, the bias fabric (V; see FIG. 2) has an oblique angle other than 90 degrees with respect to the warp (Wp) and the crossing angle (θ2; hereinafter referred to as “bias angle”) of the weft (Wt). It has characteristics that are superior in tension and durability as compared with a normal plain weave fabric (C). Such a bias fabric (V) is mainly used in various fields such as clothing collars, bands, industrial belts (automotive timing belts) and tires.

  A conventional method for manufacturing a bias fabric is briefly described as follows. First, weaving a plain weave fabric, then pulling both ends of the woven plain weave fabric in opposite directions to make a biased fabric so that the crossing angle is changed diagonally, and second, plain weave There is a method of manufacturing a biased fabric by weaving a plain weave fabric diagonally, and finally weaving the biased fabric by weaving the wefts diagonally rather than at right angles to the warp with the loom itself. There was a manufacturing method.
