Abstract In this study, the wicking properties of ring and compact-siro ring spun staple yarns were compared. The twist level, which is related to the structure of the staple yarns, was found to significantly influence the wicking property of the two kinds of yarn. Polyester staple fibers with 1.33 dtex × 38 mm were selected as the staple fiber material, and the effect of the twist level on the wicking property was investigated using the capillary rise method. The results show that with a decreasing twist coefficient, the wicking height increases with a decrease in yarn compactness. The compact-siro spun yarn showed better wicking properties owing to it special ply yarn structure. Furthermore, the tension property of the yarns decreased significantly with a decrease in the twist coefficient. Compact-siro spinning was carried out to obtain staple yarns with lower twist coefficients, and the yarns showed great improvement in terms of yarn strength, fiber straightness, and wicking properties. Thus, compact-siro spinning is an efficient method to improve the wicking properties of staple yarns.

Spinning Process

The two component filament/staple fiber core-spun yarn is spun on FA506 ring spinning frame with PTT filament as interlaced yarn and Tencel staple fiber as outer sheath. The spinning process and process parameters were analyzed. The morphology, mechanical property and wear-resisting property of two component core-spun yarn were tested. Results indicate that elastic recovery rate of core-spun is up to 90.6%; broken strength is up to 20 cN/tex after boiling water treatment. The core-spun yarn can be used as a new kind of knitting yarn for sweater.

Before And After

An assessment is made of irregularities added in apron drafting through comparisons of variance-length curves of fiber end density before and after drafting. In addition, the drafted products were examined for periodicities through correlograms. The investigations were made on a carded and a combed cotton and a cut staple fiber for a range of drafts. The studies were later extended to obtain relations of thickness irregularity with draft and hank of material fed. The implications of these results are discussed. Further, the effect of apron opening and doubling on yarn quality and a critical comparison of roller and apron drafting in regard to extent of irregularities added are presented.

The role of fiber morphology in a thermal point bonding operation was investigated. Primary objectives were to understand the changes taking place in fiber structure due to applied heat and pressure, and the role of fiber morphology in determining optimum process conditions and properties of the webs. To study fibers with varying morphology, i.e., from partially drawn as in spunbonding to fully drawn as in staple fiber nonwovens, fibers with a wide range of crystallinity and orientation were spun and characterized, from two polypropylene resins. Thermally bonded carded webs were produced, using these fibers, and characterized in order to understand thermal bonding behavior of fibers with different morphology. The fibers with different morphology differed significantly in their bonding behavior. The fibers with higher molecular orientation and crystallinity tended to form a weak and brittle bond due to lack of polymer flow and fibrillation of the fibers in the bonded regions. In general, fibers with lower molecular orientation and lower crystallinity yielded stronger and tougher webs. Fibers with relatively less developed morphology also exhibited lower optimum bonding temperature. Morphological changes in fibers were observed during the thermal bonding process, in bonded as well as unbonded regions of the web. As a final step to see how the observations from staple-fiber study translate to one of the relevant processes during scale-up, spunbond studies were also conducted in a similar way.

In this study, a novel composite siro-spinning method with cyclically migrating filaments was developed as a simple and safe way to enhance filament-staple-fiber coherence. The novel composite siro-spinning method was theoretically demonstrated to produce a yarn with migrated filaments clasping both internal and external fibers. It was predicted that migrated filaments of the novel composite sirospun yarn were not straight enough to resist yarn tensile drawing as the filament parallelism with the yarn axis decreased. However, migrated filaments could clasp the staple fibers firmly to enhance filament-staple-fiber coherence, contributing an excellent frictional resistance of the novel composite yarn. Experiments were then conducted to validate the demonstration. Experimental results proved that the novel composite sirospun yarn had cyclic filament immersion and exposure appearance, resulting in medium hairiness and yarn imperfection after comparison with corefil sirospun and siro corefil yarns. The novel composite sirospun yarn with severe filament migrations had poor filament straightness, but filament deformations that were effective in clamping staple fibers. Therefore, the novel composite sirospun yarn had less strength, but greater frictional resistance than corefil sirospun and siro corefil yarns.
