In recent years, the scientific progress has improved human life quality and changes the concepts of heath and heath care. It has been approved that the bamboo charcoal has various functions, including air cleaning, water purification, deodorization, far infrared radiation rate and anion amount. The bamboo charcoal fiber and bamboo charcoal yarn are applied extensively in the textile industry. In this study, PET fiber was used as warp, and PET fiber, bamboo charcoal nylon fiber and stainless steel fiber employed as weft to weave three groups of warp knitted fabric. The variation of far infrared radiation rate, anion amount concentration, air permeability, water absorption, flexibility of these three groups of fabric were examined. The results indicate that the far infrared radiation rate of these three groups of fabric attained 0.8. The anion amount concentration of bamboo charcoal and bamboo charcoal / stainless steel warp knitted fabrics has reached 490-495. Finally, the air permeability of bamboo charcoal / stainless steel warp knitted fabrics achieved 281 cm3/s/cm2.

As improvement of science and technology, the life quality was significantly promoted. And people are more aware of health care. It has been proved that bamboo charcoal owns special properties including air purification, water refining, deodorization, far-infrared radiation, and anion release, thus it is widely applied on textile industry in form of fiber and yarn after mixing with its power. This study aims to seek for the optimal twist number of bamboo charcoal (BC)/Nylon(NY)/ stainless steel(SS) wrap yarn. And then the one or two wrap yarns were fed into crocheting machine to weave BC/NY/SS elastic warp-knitted fabrics with different structures. Afterwards, the far-infrared radiation, anion amount, air permeability were discussed by changes of number of layers. The result shows that, as increasing layers of BC/NY/SS elastic warp-knitted fabrics, the far-infrared radiation and air permeability both decrease; but all the single-layer warp knitted fabric reaches above 0.8, corresponding with the functional standards.

Concepts Of Health

In recent years, the improvement of scientific techniques has significantly promoted the quality of peoples lives as well as concepts of health care. This study manufactures bamboo charcoal (BC)/stainless steel (SS) covered yarns, which are then made into four types of elastic BC/SS warp-knitted fabrics. The far infrared emissivity, anion amount, and air permeability of the resulting fabrics are then evaluated to determine the influence of the warp-knit structure and amount of layers. The experimental results show that the far infrared emissivity of BC/SS warp-knitted fabrics decreases when the lamination layer number increases. Single-layer BC/SS warp-knitted fabrics all have a far infrared emissivity beyond 0.8.

It is certain that bamboo charcoal has many properties, including water purification, deodorization, anion release and far-infrared ray radiation. This study aims to prepare PET/BC warp-knitted fabric composed of polyester yarn (PET) as warp yarn and bamboo charcoal polyamine yarn (BC) as weft yarn using Velcro Crochet Machine. Afterwards, air permeability, elastic resilience and far-infrared ray emissivity of resulting knitted fabric were discussed by changing weft yarn type. Result shows that, for knitted fabrics, weft yarn type cannot affect the elastic resilience; yet PET weft yarn makes air permeability decreasing.

Far infrared materials have been prepared by precipitation method using natural elbaite powder as raw materials, which belongs to tourmaline group. The chemical formula of elbaite is Na(Al, Li)3Al6B3Si6O27(O, OH, F)4. X-ray powder diffraction (XRD) shows that elbaite and alumina in composite material has good crystal form. In addition, XRD results indicate the formation of alumina crystallites show that alumina powder exists as nano-meter particles on the surface of elbaite powder. It can be calculated the particles diameter of Al2O3 is 47.86nm. The maximum infrared radiation rate of tourmaline/alumina composite materials is 0.89 when the ratio of alumina in elbaite powder is 20%. The infrared radiation rate has been increased by 0.03, compared with single elbaite. It shows that the infrared radiation rate of the composite materials is higher than any of a single component. Two reasons are attributed to the improve of the rate of far infrared radiation: alumina powder exists as nano-meter particles and different materials will increase the absorption peak and the vibration intensity in FTIR spectra.

In this research, the B/A/S composite yarns were fabricated using the stainless steel wires as core yarn, antibacterial nylon and bamboo charcoal polyester filaments as inner wrapped yarn and outer wrapped yarn, respectively. The composite yarns with a wrapping number of 8, 11, 14 turns/cm were fabricated on a hollow spindle spinning machine. Furthermore, the composite fabrics were woven with the B/A/S composite yarns as weft yarns and the PET as the warp yarns. These fabrics were evaluated in terms of far infrared (FIR) emissivity and the air permeability. The presence of the bamboo charcoal was found to increase the FIR emissivity. The highest of the FIR emissivity was obtained when the weft yarns with a wrapping number of 11 turns/cm. The lamination numbers of the woven fabrics varied from 1-5 layers. The far infrared emissivity and air permeability of the woven fabrics was 0.94 and 268 cm3/cm2/s when the lamination numbers was 2 layers and the wrapping number was 11 turns/cm.
