2016Co-Authors: Jia-horng Lin, Corresponding Jia-horng LinAbstract:In this research, bamboo charcoal/spandex (BC/S) complex Yarn was fabricated using spandex as the Core Yarn, which was then wrapped with bamboo charcoal nylon textured Yarn. The Core Yarn was first expanded and then wrapped with the wrapping Yarn on a ro-tor twister machine at speeds of 4000, 6000, 8000, 10000, and 12000 r.p.m. The wrapping amount of the BC/S complex Yarns were 2, 3, and 4 turns/cm. In order to evaluate the physical properties of the BC/S complex Yarn, the maximum breaking strength, elongation, and elas-tic recovery rate were tested. We fabricated BC/S fabrics using circular knitting based on optimal manufacturing parameters. The BC/S complex Yarn had an optimum elastic recov-ery rate of 98.89 % when the rotor speed was 10000 r.p.m and the wrap number 4 turns/cm. The optimum tenacity of the Yarn containing 44.0 dtex spandex was 4.22 cN/dtex when the rotor speed was 4000 r.p.m. and the wrap number 2 turns/cm. The anion density of the BC/S fabric increased with the wrap number; in particular, the fabric containing 76.9 dtex spandex displayed an optimum anion density of 54 anions/cc

Proceedings of the 2015 International Conference on Materials Environmental and Biological Engineering, 2015Co-Authors: Jianfei Zhang, Ching-wen Lou, Jia-horng LinAbstract:There are derivative many problems from electromagnetic (EM) wave radiation with the development of communication technique. To protect the human body from the EM radiation, in this study, the antibacterial nylon (AN)/ bamboo charcoal polyester (BC-PET)/ stainless steel wire (SSW) metal composite Yarns was produced on a hollow spindling spindle machine. In this study, we used the SSW as the Core Yarn, the AN and BC-PET as the outer and inner wrapped material, respectively. The wrapped amounts were varied from 6.5-11 turns/cm. Then, the AN/BC-PET/SSW metal composite Yarns were woven into knitted fabrics on a circular knitting machine. Moreover, we also investigated the electromagnetic shielding effectiveness (EMSE) and water evaporation rate of the fabricated metal composite knitted fabrics. Optimum EMSE –30dB was obtained at the incident frequency of 0.54GHz.

Journal of Reinforced Plastics and Composites, 2008Co-Authors: H C Chen, Jia-horng Lin, K C LeeAbstract:Copper wire and polyamide filament were used as the Core Yarn, and stainless steel wire was used as the wrapping Yarn to fabricate the loop Yarns for knitting structure. The nonwoven selvedge served as the Core Yarn, and the conducting wire was used as the wrapping Yarn, to fabricate the weft-inlaid Yarn. The rotor twister successfully fabricated a series of conductive hybrid Yarns (CHYs). The co-woven-knitted machine successfully fabricated the conductive co-woven-knitted fabrics (CWKFs) with various CHYs. The conducting materials of the hybrid Yarn were copper wire and stainless steel wire, taken as the wrapping and Core Yarn, respectively. The conductive co-woven-knitted fabrics were laminated with various angles in four and six layers and then heat pressed to 2 and 3 mm in thickness. This study investigated the surface resistivity, electromagnetic shielding effectiveness (EMSE) and electrostatic discharge (ESD) attenuation percentage of the co-woven-knitted fabrics and CWKFs reinforced composites.

parametric design of Yarn based piezoresistive sensors for smart textiles
Sensors and Actuators A-physical, 2008Co-Authors: Chingtang Huang, Chienfa Tang, Shuohung ChangAbstract:In our previous paper, the Yarn-based sensors are shown capable of measuring the respiration signals. In comparing with fabric-based sensors, the Yarn-based sensor is more comfortable in wearing, and easily fabricated by conventional textile process. In this paper, we aim at the analysis of the design parameters of the Yarn-based sensors that were fabricated by double wrapping the polyester, elastic, and piezoresistive fibers. The performances of the Yarn-based sensor under different compositions have been experimentally evaluated. It is shown that the soft-Core Yarn sensors achieve high gain factors with low linearity. The sensors consisting of high-density piezoresistive fibers achieve high linearity with low gain factor. It was also shown that the nonlinearity of the sensors that is mainly due to the irregular characteristics of the Yarn structure exits at the low strain region. As at the high strain region, the high linearity of the Yarn-based sensors is found regardless of material compositions. To further reduce irregular characteristics of the Yarn structure, to increase the preload and to choose the stiffer Core Yarn and the harder piezoresistive fibers are suggested.

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.

Effects of Core-Yarn overfeed on texturing performance: comparison between air-jet and steam-jet texturing
Journal of The Textile Institute, 2015Co-Authors: G.l.d. Wickramasinghe, Pw FosterAbstract:The objectives of this research work were to investigate the use of high-pressure steam in order to replace air in the production of spun-like textured Yarns and to investigate the optimum level of Core-Yarn overfeed ratio for steam-jet textured Yarn for the application of sewing threads. An existing air-jet texturing machine was modified to supply either air or steam to the texturing nozzle. Using an identical nozzle, both air-jet and steam-jet textured Yarns were manufactured. Loop instability and loop density increased and strength and tenacity decreased when the Core-Yarn overfeed was increased in both air-jet and steam-jet textured Yarns. Steam-jet textured Yarns have lower loop instability, lower loop density and higher tensile properties than that of the air-jet textured Yarns. Sewability results show that for both air-jet and steam-jet textured sewing threads, Core-Yarn overfeed ratios of 5.5 and 8.3% give better sewability.

Investigation of the effect of Core-Yarn wetting on air-jet and steam-jet spun-like texturing performance
Journal of The Textile Institute, 2014Co-Authors: G.l.d. Wickramasinghe, Pw FosterAbstract:The objective of the research work was to investigate the use of steam as an alternative fluid for air in spun-like textured Yarn manufacturing and to investigate the effect of wetting on texturing performance. An existing air-jet texturing machine was modified to supply either air or steam to the texturing nozzle. Both air-jet and steam-jet textured Yarns were made using the same process parameters with and without Core-Yarn wetting. The effect of Core-Yarn wetting on the texturing performance has been studied. Results show that Core-Yarn wetting is critical for air-jet texturing but do not have considerable impact on steam-jet texturing. Therefore, Core-Yarn wetting could be eliminated in steam-jet texturing. Further, steam-jet texturing shows its capability in manufacturing spun-like textured Yarns with better performance than the air-jet. Therefore, it can be concluded that steam can be used as an alternative fluid for air in making spun-like textured Yarns without Core-Yarn wetting.
