Preparation and Application of Polymer-Composited Yarn and Knit Containing CNT/Ceramic

Abstract

The properties and light-heating function of a knit prepared by the composite spinning of carbon nanotubes (CNTs) and an inorganic ceramic were examined. The CNTs and ceramic were mixed and polymerized in a master batch (MB) and the MB chip was then melt spun to prepare the CNT/ ceramic-composite yarn (LH-Yn) and single-jersey knits (LH-Knit). The properties of the LH-Yn and LH-Knit were compared with those of the regular polyester yarn (PET-Yn) and polyester knit (PET-Knit). The contents of carbon in the CNTs by energy dispersive X-ray spectrometer, scanning electron microscopy, tensile and tear performance, thermal insulation, air permeability (AP), water vapor permeability (WVP), and far-infrared (FIR) emissivity were analyzed. The result showed that the surface temperature of the LH-Knit was much higher than that of the PET-Knit. The measured WVP, AP, and FIR emissivity were also slightly higher in the LH-Knit, but the difference was not significant.

As the distinction between active sportswear and daily casual wear is difficult to verify, the multifunctionality of clothing is becoming an important factor in purchasing products (You & Park, 2007). In order for consumers to accept with the least resistance new clothing technology that will make their lives more convenient, wearable clothing should be manufactured in connection with nanotechnology (NT), which is a high-precision technology. Carbon nanotubes (CNTs) were discovered incidentally by Ijima of Japan in 1991, while he was analyzing a lump of carbon formed on a carbon cathode through an electric discharge process (Iijima, 1991). In the two decades since, CNTs have been studied extensively; one report on CNTs is published each day on average. On the other hand, the level of research about CNTs is still in the

The Influence of Fiber Cross-Section on Fabric Far-Infrared Properties

“…Currently, the normal technology for realizing far-infrared textiles is to introduce ceramic powders, including magnesium oxide, silicon oxide, zirconium carbide, and germanium compounds [19,20,21,22,23], in the textile through coating, spraying, laminating, impregnating, covering, and dipping processes [11]. In general, melt-spinning and after-treatment methods are primary approaches used in commercialized FIR textile products.…”

Obtaining of a PET/SiC hybrid multifilament: Non-isothermal crystallization studies

“…The pursuit of the increase of thermal and mechanical properties of polymeric fibres through composite materials has been an important target in the field of high performance textiles. Optically active particles to produce modulatedemissive fabrics for thermal responsive textiles (Pooley et al, 2016;Shin & Park, 2018) or biomimetic particles for developing reinforced textile-based tissue engineered scaffolds (Xue et al, 2019), are some of those examples.…”

Multiscale Finite Element Modeling of the Viscoelastic Behavior of Sportswear Under Periodic Load

“…Also, viscoelastic property is one of the significant properties of fabrics which plays an important role in the fatigue and failure of the fabric under dynamic loads (Asayesh et al, 2009;Gao et al, 2011). There are some investigations on the viscoelastic properties of the woven fabrics and textile composites (Courtois et al, 2019;Doustar et al, 2010;Shin & Park, 2017;Upadhyaya & Upadhyay, 2011;Wilson & Laing, 2019;Zhang et al, 2000). However, the literature does not exist on the viscoelastic properties of knitted fabrics and modeling of the stress relaxation of the knitted fabrics under dynamic load.…”
