“…In a steady-state twisting operation, if a fibre joins the twisting strand at a fixed point, it will be twisted to the same twist as other fibres In the strand, and, at the exit of the twisting zone, it cannot become a wrapping fibre [8] .…”

“…Atkinson and Henshaw [8] showed that, if a fibre does not converge with the main twisting strand at a fixed position but instead joins at a point that travels along the strand, it will receive less or more twist than the main bundle, depending on the direction of movement of the convergence point. This paper reports an investigation in which the Murata twin-twister principle was studied experimentally by comparing the results obtained with those for yarns spun on the more conventional Du Pont single-jet spinning system.…”

A comparison of the yams spun on three different arrangements of air-Jets shows that the Murata-type twin-Jet arrangement produces well-wrapped, strong yams.For the production of a high level of fasclatlon, it Is necessary that the distance between the front roller nip and the position at which the edge flhres contact the aain strand should he as long aa possible.If the edge fibres contact the strand close to the roller nip, they will either not produce wrapping fibres or at best produce very short wraps.An analysis of the wrapping-fibre formation Indicates that the Hurata principle Is advantageous ln creating long and effective wrapping fibres. Some of the spinning condltions are 1 nvestigated, and the reaults are interpreted In accordance with the above mechanism.

A new mathematical approach is presented to explain the structure of a jet-spun staple yarn. The mechanism of how edge fibers wrap around the yarn core is explained, and the effects of the main parameters that determine the wrapping twist are inves tigated. The important factors are the position of the edge fiber when contacting the yam core, the length of the edge fiber, and the twis level of the core upstream from the twisting element. The twisting configuration al g a single wrapping fiber is con sidered, as well as the resulting average twist of multiple edge fibers. The effect of the edge fiber length on its wrapping efficiency is also determined.
