Abstract
This paper presents the results of an investigation on the use of short staple cottons for open-end spinning. Several cottons and waste mixings 7/8-in. and less in staple length have been spun on the OE and ring-spinning systems to dif ferent counts, and yarn properties have been determined. Some of these yarn samples have been woven into selected fabrics for comparative study.
It is shown that the percent reduction of OE yarn strength over corresponding ring-yam strength depends both on the properties of the cotton and the count of yarn spun from it. OE-spun fabrics have significantly lower breaking strength, tearing strength, and bursting strength than ring-spun yarn fabrics; however, the breaking elongation, air permeability, and abrasion resistance are not substantially altered. Thus when using OE yarns, one must consider changes in fabric construction to optimize the properties of the yarn used.
