Weaving Machinery and Its Related Technologies

Abstract

Published research work concerning weaving machinery and its related technologies in the period between 1990 and 2005 are surveyed in this review. Air-jet looms have been introduced to a lot of weaving mills widely and rapidly in spite of their uncertainness of weft running. Thus researchers concerned with weaving machines have paid a great interest in air-jet weft insertion technology. Developments of measuring devices, photographic technology, control devices, and personal computers brought active research work in the fields of the air jet weft insertion: especially spreads of personal computers have facilitated to solve almost all types of equations of motion. In consequence, numerical simulations for weaving machines have been easily performed including weft insertion, warp tension, mechanism design for loom and so on.

Braiding, twisting, and weaving microscale fibers with capillary forces

“…However, it may be possible to make weaves that consist of multiple layers with machines that use switches to swap fibers in two-dimensional arrays. Second, we do not yet have a way to rapidly insert weft fibers between multiple warp fibers at once, as is done by the rapier or air-jet mechanisms 26,27 in industrial weaving machines. Such mechanisms may be difficult to replicate in our capillary machines because fluid drag makes it difficult to move carriers at a high speed along the interface.…”

“…26 In some industrial weaving machines, the weft fibers are inserted by fast-moving rapiers or air-jets between sets of raised and lowered warp fibers. 26,27 We can use the mathematics of braids to describe the topologies of these textiles. Braids can be defined by the order of swaps between neighboring fibers.…”

Measuring unsteady axial velocity of fibres and threads

“…are found in the weaving machinery (e.g. [1]) where, for example the thread or fibre weft in a shuttle-less loom is moved axially as it is inserted into the shed formed between the system of warp threads (Fig. 2).…”
