The earliest type of loom, and still the most commonly used in the production of fine fabrics, is the shuttle loom, so named because the weft yarns are woven into the warp yarn sheet by being carried across the width of the fabric on a shuttle. Other means of weft insertion include the...
Figure 5.5(b) shows the passage of warp yarn through various parts of a loom fitted with a negative tappet shedding mechanism.7 The shedding cams (tappets) get their rotary motion through the bottom shaft on which they are fitted. When the tappets rotate, they depress ‘followers’ (called...

Independent movement of the heald shaft (1) is carried out by the grooved tappet (7) with the help of rigid connecting rods (constraints) (2, 3, 4, 5, 6). The fabric structure can contain up to 10 various interlacings of warp threads. Each heald shaft requires its own tappet. A ...
Fig. 6. The schematic diagrams of (a) weft knitting and (b) warp knitting. In the conventional hand knitting, loops are obtained by pulling through a yarn form a row of stitches to another. As in the machine knitting, each needle is responsible for its own stitch, pulling the yarn thro...
Silk has played an important role in the development of loom and weaving technology. Traces of primitive looms and woven fabrics have been found in excavations in Egypt, China, India, and Peru, but these tribal 2-bar bamboo devices, including later improved shaft looms – horizontal and verti...
It created a huge mass market for sophisticated fabrics that previously had been available only to the very wealthy. As Fig. 1.2 shows, a fabric consists of threads in both x, known as the weft thread, and the warp thread in y. The loom's shuttle moves the warp thread back and forth...
Shuttle looms can weave silk fabrics efficiently, and a high speed machine ensures a high-quality warp and weft. The number of knots, cleanness, and cohesion are also important. In recent years, silk weaving has seen drastic changes both in the use of sophisticated looms and weaving ...
