An Experimental Study of an Open-end Disc–spinning Concept
Journal of the Textile Institute, 1992The basic principle of a novel open-end-spinning technique, termed disc spinning, is described. In this technique, the four fundamental actions common to other open-end-spinning methods occur simultaneously but separately, in particular those of fibre collection and twist insertion. Results are given of ‘proof-of-concept’ experiments undertaken.

23—THE SIGNIFICANCE OF YARN TENSION IN OPEN-END SPINNING
Journal of the Textile Institute, 1976The theortical relation between yarn-mass variation and the variation of yarn-spinning tension for open-end rotor-spinnig is derived, and it is shown experimentally that spinning-tension measurement represents a useful means of assessment of yarn irregularity.

43—HIGH-SPEED OPEN-END ROTOR-SPINNING
The Journal of The Textile Institute, 1975High-speed open-end rotor-spinning is discussed in relation to the properties of yams spun in the speed range from 30,000 to 100,000 rev/min. The design of the rotor and its modified driving unit is described in detail. The properties of the yarns with respect to strength and strength variation, extension at break, and short-term yarn evenness are ...

Yarn Evenness in Open-End Spinning
Textile Research Journal, 1974Open-end yarn is said to have a better evenness than ring yarn, but the truth of this statement depends on the error wavelength. It is shown that errors are reduced when the error wavelength in the yarn is less than the circumference of the collecting surface.

Theory of Semi-open-end Ring Spinning
Journal of Fashion Technology & Textile Engineering, 2017In this paper we propose a novel spinning named semi-openend ring spinning. To discuss the theory, an infinitesimal cylinderchained fiber model is established, the differential Equations of the infinitesimal cylinder at different moment are established and revolved by Runge-Kutta integration.

Perforated-Groove, Self-Cleaning, Open-End Spinning Rotors
Textile Research Journal, 1979This progress report describes a new type of self-cleaning, open-end spinning rotor. Rotors were modified by drilling holes of different numbers, sizes, and angles in the rotor groove. Accumulation of rotor dust was significantly less for the perforated than for the control rotors. The perforated rotors removed short fiber as well as dust and produced
