2、riness of Polyester/Cotton Blended Ring-Spun Yarns Made from Different Blend RatiosSuat Canoglu1 and S. Kevser Tanir Department of Textile Education, Marmara University, Göztepe, Istanbul 34722, TurkeyHairiness is

3、 one of the important parameters for spinners and for further processing in textiles. Some researchers [1] indicate that for cotton yarns the statistical distribution of the number of protruding ends of different lengths

4、 is expo- nential. On the other hand, due to the hairiness in the yarn, some defects on the fabric may appear. Some examples include warp draw-in and warp yarn tangling during the weaving process and hence warp yarn brea

5、kages, pilling on the knitted and woven fabrics, and some defects on the appearance of fabrics [2]. From the beginning of the 1950s, hairiness became one of the measurable yarn parameters and since then has been used reg

6、ularly in yarn testing. Yarn hairiness is affected several parameters, so is difficult to prevent [3]. It is defined as protruding ends of yarn from the yarn body and the factors that affect it include type of fiber used

7、, production methods, yarn, machine parameters,etc. [4,5]. Some previous studies [6,7] have reported that the cause of hairiness (i.e. short fibers, long fibers, fiber bridges, fiber loops, loose fibers, vertical fibers,

8、 etc.) is due to the positioning within the yarn body, which can be seen from photographs taken with an scanning electron micro- scope (SEM).1In this study, 36 tex polyester/cotton yarns were spun with five blend ratios

9、and with two traveler weights [8]. The changes in yarn hairiness and other yarn properties were investigated during the spinning of yarns using different traveler weights. Then the changes of yarn hairiness varia- tion a

10、nd other yarn parameters were observed from SEMAbstract In this study, 1.4 denier and 32 mm of fiber-length polyester and 30.2 mm fiber-length cotton (4.35 micronaire) rovings of 695 tex (αtex = 10.7) were blended with d

11、ifferent polyester/cotton ratios (i.e. 17/83, 33/67, 50/50, 67/33, and 83/17). The yarns were produced at a spindle speed of 11,000 rev/min with a 42 mm ring diameter, where C-type half round travelers of 85 and 95 mg we

12、re employed in ring frames. The resulting 36 tex (αtex = 37.5) yarns were examined by measuring their tensile strength, elongation, count, twist, even- ness, and hairiness. Then the yarns were knitted into fabrics to obs

13、erve and evaluate pilling per- formance. The observations based on scanning electron microscope (SEM) images were con- cluded both on the hairiness and pilling values, depending on the blend proportions. Among the yarns

14、produced, the best hairiness with the trave- ler of 95 mg weight was obtained from the blend yarn with a polyester/cotton ratio of 33/67 and the best pilling parameter was accrued from the knit- ted fabrics with a polyes
