dc.description.abstract In the early 1980s, widespread claims in the knitting industry suggesting that the use of open-end yarns significantly increased the wear of mechanical components, especially knitting needles. Since then, many studies have attempted to explain this phenomenon and have yielded widely varying results. A study was conducted to compare the yarn properties of open-end yarn to ring-spun yarn. Identical yarns of varying parameters including yarn type, yarn count, and twist multiple were produced from the same raw cotton stock to eliminate variability in raw material. These yarns were tested for abrasiveness on a Lawson-Hemphill CTT (Continuous Tension Transport) tester. The device passes the yarn over a wire and records the length of yarn required to sever the wire. For this study the CTT was encoded to abrade a fixed length of yarn over the wire. The wire was then observed with both a Hitcahi ESEM (Environmental Scanning Electron Microscope) and a digital imaging microscope. The resultant images were examined for attrition and the abrasion values were evaluated using statistical analysis. It was confirmed that an increase in yarn count corresponded to a decrease in abrasion. Twist multiple had a noticeable effect on abrasion although the trends between yarn types, and yarn counts were inconsistent. Open-end yarn abrasion values were only slightly greater than their ring-spun counterparts, contradicting the claims of the knitting industry. en_US
