Evaluation of the Yarn Properties of a High- Strength Interspecies Cotton

Abstract

The reported results compare the yarn properties of a high-strength (11.5 Pressley Index) Interspecies cotton with those of five other cottons having a comparatively wide range of fiber properties. The cottons were processed alike on conventional processing equipment into 18/1, 36/1, and 72/1 carded yarns using a range of twist multipliers from 2.75 to 5.75. The sliver and roving made from each cotton were measured for uniformity and the yarns were tested for uniformity, appearance, and strength. It was found that yarns made front the Interspecies cotton were as strong as those made from the much longer and finer Karnak cotton and stronger than those made from the other cottons. The Interspecies and Karnak yarns were about equal in uniformity with both being more uniform than the other control yarns.

A limited statistical analysis of yarn breaking strength data indicated that fiber strength is more important to yarn strength than either fiber fineness or length.
