ower in
power-looms, but the arrangements for both are to a certain extent the
same. A great number of different kinds of power-looms are
manufactured for producing the various classes of textiles in use at
the present time. These looms are distinguished by the name of the
material which they are designed to weave, as the ribbon-loom,
blanket-loom, burlaps- and sacking-loom, plush-loom, double-cloth
loom, rug-loom, fancy cotton-loom, silk-loom, worsted-loom, etc.

Weaving is distinct from knitting, netting, looping, and braiding,
which are operations depending on the interlacing of a single thread,
or single set of threads, while weaving is done with two distinct and
separate sets of threads.

=Classes of Weave.= The character of the weave offers the best basis
for classification of woven goods. Nearly all the varieties of cloth
may be classified from the following weaves:

(1) Plain-weaving,
(2) Twill-weaving,
(3) Satin-weaving,
(4) Figure-weaving,
(5) Double-cloth-weaving,
(6) Pile-weaving,
(7) Gauze-weaving,
(8) Lappet-weaving.

=Plain or Homespun Weave.= Plain cloth is the simplest cloth that can
be woven. In this weave one series of threads (filling) crosses
another series (warp) at right angles, passing over one and under one
in regular order, thus forming a simple interlacement of the threads.
This combination makes a strong and firm cloth, but does not give a
close or a heavy fabric, as the threads do not lie as close and
compact as they do in other weaves. In plain cloth, if not fulled or
shrunk in the finish, the result is a fabric perforated with large or
small openings according to the size or twist of yarn used. If heavy
or coarse threads are used the perforations will be large; if finer
threads, the perforations will be smaller.

This weave is used in the production of sheeting, muslin, lawn,
gingham, broadcloth, taffeta, etc. In plain weaving it is possible to
produce stripes by the use of bands of colored warp, and checks where
both warp and weft are parti-colored. This weave is commonly used when
the cloth is intended to be ornamented with printed patterns. In
weaving cloth of only one color but one shuttle
