STUDIES ON RABBIT FIBRES

(XIV) RELATION BETWEEN THICKNESS OF ANGORA RABBIT FIBRES AND CARROTTING

Abstract

The mechanical properties of the untreated and carroted fibres of varying cross-sectional area were tested and the following results were obtained.
1. The 30%-extension work per unit volume increases as the fibre becomes thick in the case of the non-medullated one, whose cross-sectional area is smaller than 200μ², but it is independent of the thickness of the medullated fibre, whose sectional area is larger than 200μ². The relation holds similarly for the untreated and the carroted fibres.
2. The recovery work of the carroted fibre shows the same behavior, while that of the untreated one is independent of the sectional area for the range of 100_??_1500μ².
3. The resilience of the carroted fibre is almost constant, but that of the untreated fibre decresesa as the sectional area increases.
4. The hysteresis of the untreated and carroted fibres increases similarly till the sectional area increases to some 500μ² and thereafter remains constant.
