26—A NEW HAIRINESS METER FOR YARNS

The Journal of The Textile Institute, 1980
The fundamental principles on which a new electronic digital hairiness meter is based are described; an example is included to show its application to the study of the hairiness of a cotton yarn.

A Process to Control Hairiness in Yarn

Journal of the Textile Institute, 1992
Hairiness is a parameter of interest to the textile technologist. The material and the machines used both influence the fuzziness of yarn. This paper reports the results of a preliminary investigation in which fuzziness is reduced by increasing the pressure of air around the point of twisting.

YARN HAIRINESS: THE INFLUENCE OF TWIST

Journal of the Textile Institute Proceedings, 1957
In this paper the various causes which determine yarn hairiness are studied with particular reference to the influence of twist. A theory of the causes of hairiness in cotton, worsted and spun rayon yarns, which is based on the work of Morton and Yen concerning the migration of fibres in yarns, is outlined.

Recent research and developments on yarn hairiness

Textile Research Journal, 2014
Hairiness is an important quality parameter of spun yarns. It not only affects the quality of yarns, but also the weaving and knitting performance of yarns as well as the quality of the resultant fabrics. Various developments regarding yarn hairiness have been reported in the last decade.

NEW CONCEPTS OF YARN HAIRINESS

Journal of the Textile Institute Proceedings, 1956
A study of the distribution of fibres projecting from the core of a yarn along its length shows that these fibres are most numerous at the thickest and least twisted parts of the yarn. The number of projecting fibres per millimetre of yarn length has been used as a new parameter, allowing hairiness to be defined independently of the conditions ...

35—AN INSTRUMENT FOR THE STUDY OF YARN HAIRINESS

Journal of the Textile Institute Transactions, 1964
An instrument is described that enables the number of fibres protruding from a yarn to be counted at different distances from the axis. The data from several yarns may be compared directly or, since the data fit a Γ-type distribution, parameters may be calculated that describe the mean length, in a radial direction, the total radial length of all the ...

Yarn hairiness determination using image processing techniques

ETFA2011, 2011
This paper presents a method to automatically determine yarn hairiness using Image Processing (IP) techniques. After image acquisition, the samples are analyzed and processed by a custom-made application developed in Lab VIEW from National Instruments with the IMAQ Vision toolkit.

25—USE OF A YARN HAIRINESS METER AND RESULTS SHOWING THE EFFECT OF SOME SPINNING CONDITIONS ON YARN HAIRINESS

Journal of the Textile Institute, 1968
An instrument developed for the measurement of yarn hairiness—the Yarn Hairiness Meter—has been in use by the Spinning Technology Department of the Shirley Institute for the past three years, and this paper gives the procedure to be adopted in using the instrument and results showing the effect of some spinning conditions on the hairiness of yarns spun
