Designs in Sunken Effects
Fig. 1 is an illustration of a pattern where the sunken effect is well distributed. This pattern also shows the operation of two sets of figure threads brought up alternately. Both warps are buried to allow the back filling to appear in relief. This indicates the wide scope of design possible on a single shuttle, which is almost unlimited.
Fig. 2 illustrates a double shuttle design which has a sunken warp effect in connection with a silk figure. It also serves to illustrate the effect of skein dyed silk for decorative purposes. Fig. 3 shows still another type of double shuttle design, in which a parti-colored face warp lends an entirely different effect to a design. Fig. 4 is an example of three shuttle work where one shuttle is used for the ground, and two shuttles for the silk figure.
It would be easy materially to enlarge on the various types of design possible in jacquard weaving of elastic webs but this is not necessary. If a straight tie-up is used the scope of design is almost unlimited. The custom generally adopted is to operate the back, rubber and gut from chain or cam harness, as the same movement of all these threads is maintained continuously, and to operate the face and binder from the jacquard. Fig. 5 is an illustration of a fully rigged jacquard suspender loom, having two machines mounted on it, and with the back and rubber harness operated by the fancy head.
