THE MECHANICS OF RUPTURE OF COTTON-DACRON BLENDED YARNS
Abstract
The tensile behavior of cotton-Dacron blends was studied in a twisted model yarn structure composed of Dacron filament yarns (70 denier, 34 filament) and combed cotton staple yarns (79 cotton content (c.c.)) in blend ratios of 1. 1, 2.2, 11, 22, 33, 44, 56, 67, and 89 percent cotton content. The contribution of the cotton component to the blended structure at all strain levels is the main subject of the study. The report covers the experimental studies on the load extension characteristics of 72 model yarns at elongations of 5 percent through break and the effect of twist (0.55 twist multiple (TM) through 4.4 TM), blend ratio and position of the cotton component in the yarn (cotton core or cotton shell) on the strength of the blended yarn are discussed. These studies extend Machida's theoretical approach to the problem of blended yarn strength to include cotton-Dacron blended yarns in blend ratios of practical significance.
