Excerpt: ...more probable that a point has been reached at which the art of textile design attains to a leading place; but this art, nevertheless, may be most conveniently based upon the foregoing more or less scientific conditions. Certainly the following particulars, along with those already given, will prove most useful to the practical designer. A recognised method of research is to go to extremes, and this method may be well applied here. The cloths so far considered have been formed with both components--warp and weft--bending equally; now the two extreme types--viz., those in which weft only bends, the warp being perfectly straight, and those in which the warp only bends, the weft being perfectly straight--must be considered. The first are termed weft-rib structures, because the ribbed surface is formed by the weft; and the second warp-rib structures, because the ribbed structure is formed by the warp. Weft-rib-Structures.--'I'he conditions of weft-rib structures are shown in Fig. 41, drawn in a similar manner to Fig. 39, but with all the warp-thread sections d, d in a straight line, the weft e, e doing all the bending. It is at once obvious that the condition is more or less unnatural, for unless (I) the threads d, d are much thicker than the picks e, e, causing them to bend, or (2) the threads d, d are pulled straight in the finishing operation, it is evident that this structure is impractical and simply a result obtained on paper. But suppose the result is possible, what is the distance apart of the warp threads? for this, to the designer, is the main question. Now, it is evident that the threads may be any distance apart greater than the diameter of the weft, but if a weft angle of 60 with the warp is considered suitable, then the...
