method of producing a polyester viscose core spun yarn containing spandex using a modified Ring Spinning Frame
Textile Research Journal, 2001Co-Authors: Osman BabaarslanAbstract:Core yarns are known as multi-component yarns in which one component, the core material, stays nearly at the center of the yarn while the others cover it. Stretch knitted or woven fabrics can be made from core yarns in which the core is an elastomeric filament such as Dorlastan®, Lycra®, Glospan®, etc., and the coveRing is made from staple fibers. Elastomeric core-spun yarns are usually made on cotton, worsted, or woolen Spinning systems. In this study, we briefly describe a method of producing a polyester/viscose covered Lycra core yarn on a modified short-staple Ring Spinning Frame. We also examine the polyester/viscose staple yarn and the polyester/viscose core-spun yarns produced on the modified system. The experiment and test results show that core positioning has a direct effect on the structure, properties, and performance of these core-spun yarns.

Comparison of Cotton/Polyester Core and Staple Blend Yarns and Fabrics
Textile Research Journal, 2016Co-Authors: George F. Ruppenicker, A.p.s. Sawhney, R.j. Harper, K.q. RobertAbstract:Cotton wrapped polyester core yams produced on a modified Ring Spinning Frame were compared with yams spun from staple fiber blends. The yams contained ap proximately 70% cotton and 30% polyester. Yarns and fabrics made from both regular and high tenaeity polyesters were evaluated. Fabrics produced from the core yams were stronger and more durable than those of the staple blends, and they maintained their superiority in these properties through wet processing and resin .finishing. Other advantages of the core-yam fabrics included better cover and abrasion resistance.

Selected Properties of Predominantly Cotton Staple-Core Knitted Fabrics
Textile Research Journal, 1995Co-Authors: L.b. Kimmel, A.p.s. SawhneyAbstract:This study of single-jersey knit fabrics is the first to examine the basic properties of staple-core knits. Prior studies revealed certain functional and aesthetic advantages of woven staple-core fabrics when compared to 100% cotton or intimate-blend fabrics of the same construction. In this study, nominal 20s count staple-core yams have been spun on a Ring Spinning Frame that incorporates patented modifications. The staple-core yams contain a high tenacity polyester core and a cotton sheath comprising two-thirds of the yam. The fabrics are knitted on a single-feed jersey knitter with a 88.9 mm (3.5-inch) diameter, 20-gauge cylinder. Fabric properties are examined after five home-laundeRing cycles, in the greige state, after scouRing, and after scouRing and heat setting. The staple-core knits are stronger, less permeable, and significantly more abrasion resistant than the cotton controls. They also show less differential shrinkage and look consistently better than the controls after laundeRing. Greater sp...

Improved Method of Producing a Cotton Covered/Polyester Staple-Core Yarn on a Ring Spinning Frame
Textile Research Journal, 1992Co-Authors: A.p.s. Sawhney, K.q. Robert, George F. Ruppenicker, Linda B. KimmelAbstract:A new, better method of producing cotton covered/polyester staple-core yarn on a modified Ring Spinning Frame is described. The method uses the concept of twisting a “sandwich” formed by two drafted strands of cotton (rovings) on the outside and a drafted strand of polyester on the inside, thus using a total of three rovings. The earlier method used only one cotton roving and one polyester roving [10]. The new method is simple and easily adaptable to the existing Spinning Frames; piecing of broken ends is also easy. A 67/33 cotton/high tenacity polyester staple-core yarn produced by the new Spinning system is evaluated. The core of the yarn is almost totally covered with a firm sheath of cotton, giving the an appearance of a 100% cotton spun yarn. Compared with conventional yarns of 100% cotton and 67/33 cotton/polyester intimate blends, the core yarn is significantly stronger than the equivalent 100% cotton yarn and the intimate blend yarn of regular tenacity polyester. These yarns may be useful where a ...

Exploratory Work on the Spinning Condition of the Structure of Staple-core Twin-spun Yarns
Textile Research Journal, 2009Co-Authors: Yo-ichi Matsumoto, Hiroyuki Kanai, Hirokazu Kimura, Kazunari FukushimaAbstract:In order to design and develop novel-spun yarns with good functionality, we investigated how to construct a core-sheath structure adapted from a multilayered structure of triplet-spun yarn and/or made from a twin-spun yarn with core-staple fibers using an experimental Ring-Spinning Frame. The results were follows: (1) staple-core twin-spun yarn, a new yarn, could be made by applying the production method of triplet-spun yarn and/or combining the production methods of core-spun yarn and twin-spun yarn into one twisting process; (2) by adopting three rovings made from fibers of diffeRing length and fineness, the resulting triplet-spun yarn had the core-sheath structure within an adequate Spinning condition; (3) for the construction of core-sheath structure, it is important that there be a difference between Spinning tensions at the center and the two sides of the drafted fiber strands or drafted strand lengths from the front roller nip to the point of yarn formation by controlling the distance of the supply...

Characteristics of Novel Triplet Spun Yarns Made from Fibers of DiffeRing Fineness
Textile Research Journal, 2009Co-Authors: Yo-ichi Matsumoto, Takanori Yamamoto, Hirokazu Kimura, Toshio Matsuoka, Kazunari FukushimaAbstract:In order to reduce the hairiness of Ring spun yarns and to develop novel multilayered spun yarns, we investigated the properties of triplet spun yarns made from the same size of three rovings with different fiber fineness using an experimental Ring Spinning Frame. The results were: (1) different fiber fineness triplet spun yarn, a new yarn made by combination staple fibers of three different fineness into one twisting process; (2) although triplet spun yarn had a side-by-side structure in the cross-section, the central angle made by the assembly of finer fibers was smaller than that of coarser fibers; and (3) in comparison with single yarn, triplet spun yarn had less hairiness and greater strength because of the lower Spinning tension of each strand and the twist propagation in each strand.

Research on performance of twin-core spun yarn and fabric
International Journal of Clothing Science and Technology, 2019Co-Authors: Xuzhong SuAbstract:Purpose As one kind of filament/staple fiber composite yarn, core spun yarn has been widely used, especially on Jeans. However, there is only one filament in the commonly used core spun yarn, such as spandex, and the performance of the one filament often is influenced duRing dyeing and finishing. Therefore, in the paper, twin-core spun yarns with two different filaments feeding simultaneously were spun on Ring Spinning Frame modified by one kind of filament feeding numerical control device. The paper aims to discuss these issues. Design/methodology/approach Four kinds of twin-core spun yarns, cotton/spandex/PBT, cotton/spandex/CM800, cotton/spandex/T400, cotton/spandex/SPH with linear density 36.4tex/40D/50D were spun. For improving the coveRing effect of the two filaments, the filament feeding position, filament pre-drafting multiple, distance between two staple roving, designed twist factor of the core spun yarn were optimized. Findings It is shown that compaRing with the core spun yarn, the breaking strength and elongation of the twin-core spun yarns are improved since the addition of another elastic filament, while the evenness is a little worse. Originality/value By using the twin-core spun yarns, corresponding knitted and woven fabrics are produced. Meanwhile, for simulating the dyeing and finishing process, the knitted fabrics were treated duRing the 150°C high temperature. It is shown that compaRing with the fabrics produced by cotton/spandex yarn, addition of another elastic filament can improve the fabric strength and resistant and has positive effect on worsen prevention for high temperature treated fabric elastic recovery, and on change prevention duRing the dyeing and finishing process for fabric handle properties, and improves the fabric stability.

Study on Spinning triangles in the common Ring Spinning and Super draft Ring Spinning systems
Fibers and Polymers, 2016Co-Authors: Xuzhong SuAbstract:In the paper, one kind of super draft Ring Spinning Frame with four drafting rollers and corresponding three drafting zones were introduced. The yarn qualities spun by the super draft Ring Spinning Frame were analyzed by studying the shape of Spinning triangles. Using the high speed camera system OLYMPUS i-speed3 and one kind of transparent front top roller, the Spinning triangles were captured, and the geometry size of Spinning triangle were measured. Then, according to the theoretical model of fiber tension in the Spinning triangle, fiber tension distributions in the Spinning triangles were presented by using Matlab software. Using the combed roving of 350 tex as raw material, three kinds of cotton yarns, 27.8 tex (21S), 18.2 tex (32S) and 14.6 tex (40S), were spun in the common Ring Spinning Frame with three different suitable spindle speeds, travelers and twist factors. Using the combed roving of 350 tex and 500 tex as raw material, 14.6 tex cotton yarns were spun in the super draft Ring Spinning Frame with three different drafting ratios at back zone. It is shown that with the increasing of spindle speed, a more asymmetric shape of Spinning triangle would be produced, and lead to worsen yarn evenness. With the decreasing of traveler weight, the height and horizontal deviation of the Spinning triangle is decreased, and may lead to better yarn evenness and less long hairiness. By taking suitable large yarn twist factors, the comprehensive qualities can be improved. CompaRing with the common Ring Spinning, the Spinning triangle is larger in the super draft Ring Spinning. That is, in the super draft Ring Spinning, the fibers in the strand in the front roller nip are more dispersed, and not benefit for yarn qualities. Therefore, the compact device was introduced into the super draft Ring Spinning, and the cotton pure yarns and blend yarns were spun, and the yarn qualities were measured and analyzed.
