PLS regression analysis for length-diameter blended yarns


PLSregression analysis for length-diameter blended yarns

Uniformfibers were determined to produce highly tenacious yarns. Thisbehavior is in agreement with the results of El Mogahzy (1988) whichpostulate that skein factor increases as the length and uniformity ofthe fiber increases, but decreases as the fiber fineness and Rdincrease(ElMogahzy 1988,p. 395).Some researchers argue that the nature of elongation of the fibersthat make up the yarn plays a significant role in influencing theextension of ring-spun yarns. The level of stretching of yarn iscritical in determining the weaving efficiency.

Thetenacity of the yarn helps in evaluating the weaving performance(Guha, Chattopadhyay, &amp Jayadeva 2001, p.139 ).The variation in hairiness of the yarn is as a result of changes inthe length and uniformity of the fiber. The results obtained supportthe findings by other researchers that the rise in the length of thefiber lessens the hairiness of the yarn. According to Viswanathan et al. (1989),the hairiness of the yarn is mostly affected by the fineness of thefiber.

Yarnsshould have at least some hairiness to enhance coverage and comfortin fabrics, as well as increase the rate of insertion of wefts whenweaving, particularly due to the friction between the air surface andyarns (Konda, Okamura, &amp Merati, 1996). Nevertheless, when thelevel of hairiness exceeds a certain degree, the appearance, andtension on yarns are affected. This, in turn, has an impact on theproperties of the fabric. According to Adanur and Jing (2008), anincrease in hairiness from 1750 1750to 2500 cnt/1000m in the course of 3/1 leads to increase in thefilling tension on the yarn by 53 percent and 145 percent for 35 andsingle picks respectively.

Thechanges that were determined in filling tension were as a result ofhairiness, count, and a twist of the yarn interacting in a complexmanner, and this suggests that when the hairiness of the yarnincreases, the performance of the yarn and quality of resultantfabric reduces. Nevertheless, the variations in hairiness of the yarnwere not predicted well using the changes in characteristics of thefiber for the samples that were analyzed.
