The strength of rotor-spun yarns is usually lower than that of ring-spun yarns. One of the
major factors which affect the strength is the fiber morphology. Better understanding of the …

One of the most important operations in rotor spinning is the transportation of separated
fibers from the feed to the rotor chamber through the transport channel. Any disturbance in …

The effects of rotor speed (417 to 1000 rev/s) on yarn quality were investigated. The
following parameters were also varied: rotor diameter and configuration, card type, cotton …

Rotor spinning is an open-end spinning method that uses air as the medium to transform the
fibers into yarn. Nowadays, the properties of its final product—yarn—such as yarn strength …

Open-end rotor-spun yarns, unlike ring-spun yarns, are basically of a three-part construction:
a tensely packed core of (straight) fibres substantially aligned with the yarn axis, more …

This paper is the first part of a series investigating yarn twist propagation in rotor spinning
and methods to produce modified rotor spun yarns. Here. an integrated mechan ical …

The impact of rotor and opening roller speeds on the configuration of fibre in yarn has been
studied using the tracer fibre technique. An increase in opening roller speed first increases …

To interpret why rotor-spun yarns have fewer straight fibers, numerical simulations are
performed to explore the fiber dynamics and morphological evolution during its conveyance …

An intensive study has been carried out to define the structure of rotor-spun yarns objectively
and to find out the contribution of structural parameters to yarn properties. It is observed that …

By analyzing yarn motion and yam dynamics in rotor spinning, this paper provides an
analytical model to determine the twist level at the peeling point in rotor spinning. The model …
