Upon observing Figure 2, it will be noted that the smooth continuity of the waviness of the moir stripes is interrupted where they encounter the spot areas l4 and I5. The interruption usually manifests itself by a lateral displacement of the stripe, but sometimes the interruption is of a different character and one stripe may seem to merge with the adjacent one, or to vary from its basic waviness in some other manner. This result is directly attributable not only to the fundamental nature of the moir treatment, but also to the spacing and general nature of the original dobby figures.

The ultimate unique ornamental eflect is characterized by the spaced dobby figures, by the spaced wavy moir stripes, by the spaced spot impressions made by the dobby figures, themselves,

It will be understood that my invention is applicable to fabrics in a variety of ways. For example, the present unique ornamentation may extend completely across the full width of the fabric, or it may extend across only a partial width. Sometimes it may be desirable to provide the present ornamentation in spaced areas, and to provide other ornamentation or an absence of ornamentation in the intermediate areas.

Having thus described my invention, and illustrated its use, what I claim as new and desire to secure by Letters Patent is- 1. An ornamental moired textile, comprising the spot impressions thereof.
