Weaving process

Sieving Methods and Classification Sieving is probably the most frequently used and abused method of analysis because the equipment, an ytical procedure, and basic concepts are deceptively simple. In sieving, the particles are presented to equal-size apertures that constitute a series of go-no-go gauges. Sieve analysis presents three major difficulties (1) with woven-wire sieves, the weaving process produces three-dimensional apertures with considerable tolerances, particularly for fine-woven mesh (2) the mesh is easily damaged in use (3) the particles must be efficiently presented to the sieve apertures.

This same study also determined that the weaving process used to fabricate the carbon cloths plays an important role in the final thickness of the material. 

Water-soluble sizes permit a recycling of the polymer for further weaving processes. Various techniques have been proposed to regenerate sizes released from the fabric. General requirements that have to be considered as fundamentals for possible reuse of sizes are summarized as the following ... 

Basic yarn components along with conventional filaments/yarns constitute the feedstock of the weaving process. Selectively fed into a loom and manipulated through an advanced textile manufacturing process, this feedstock can be woven into a complex variety of designs that result in a structurally sound, environmentally compatible fabric that provides electrical and mechanical functionality. Electronic circuits can be formed from the selective interconnection of fibre components during the weaving process. 

Sieve cloth is woven from wire and the cloth is soldered and clamped to the bottom of cylindrical containers [10,13]. Although the apertures are described as square, they deviate from this shape due to the three-dimensional structure of the weave. In the weaving process, the weft wires are crimped on to the warp wires for added strength vigorous cleaning, for example with a wire brush, can separate the wires leading to oversize apertures. Fine sieves are usually woven with phosphor bronze wire, medium with brass, and coarse with mild steel. 

Solid fats, like tallow, are sometimes used as lubricants on sized warp yarns in shuttle looms. Without such lubricants, warp yarns can unravel and break as a result of the abrasion of the size by the shuttle and the heddle. This would introduce defects in the fabric and will also affect the efficiency of the weaving process. In knitting, the lubrication of the yams is also important. Lack of lubrication results in nonuniform yam movements that affect the quality of the fabric. 

In the weaving process what strands to use of course will depend on a teacher s individual interests, the subject, the particular group of students, and the general cultural climate. On the other hand. Doc felt one strand so important that provision should be made always for at least one teacher of a technical subject to weave it into the professional education of a chemical engineer at some point in the enterprise. This strand is history.
