Abstract

Two long staple cottons, differing in fiber bundle break elongation but having other pertinent fiber properties substantially equal, were blended in different percentages to permit a study of the effects of break-elongation on yarn properties and spinning etbciency.

Yarn strength and elongation were affected by fiber elongation, with fibers having the highest fiber elongation exerting the greatest influence. Furthermore, nep formation increased linearly as the percentage of higher elongation cotton increased in the blend, indicating that neps are directly influenced by average fiber stiffness.

It was also found that yarn toughness index correlated closely with yarn impact data, thus suggesting its possible substitution for yarn impact data.

The inconsistency of end breakage of the warp and hlling yarns during spinning offered no conclusive evidence as to the relative spinnability of the cottbns and cotton blends investigated.
