  • structure and thermal properties of bamboo viscose tencel and conventional viscose fiber
    Journal of Thermal Analysis and Calorimetry, 2007
    Co-Authors: Ying Xu, Z Lu, R. Tang
    Abstract:

    Comparative investigations of new regenerated cellulosic fibers, bamboo viscose fiber and Tencel, together with conventional viscose fibers have been carried out to explain the similarity and difference in their molecular and fine structure. The analyses jointly using SEM, XRD and IR reveal that all the three fibers belong to cellulose II. Tencel consists of longer molecules and has a greater degree of Crystallinity, while bamboo viscose fiber has a lower degree of crystallinty. TG-DTG-DSC study shows three fibers resemble in thermal behavior with a two-step decomposition mode. The first step is associated to water desorption, suggesting that bamboo viscose fiber holds better water retention and release ability, the second a depolymerization and decomposition of regenerated cellulose, indicating that Tencel is more thermally stable in this process than bamboo and conventional viscose fiber.

  • polyethylene keratin fiber composites with varying polyethylene Crystallinity
    Composites Part A-applied Science and Manufacturing, 2005
    Co-Authors: Justin R. Barone
    Abstract:

    Short-fiber reinforced composites are made from keratin fibers obtained from poultry feathers and polyethylenes of varying Crystallinity. The chemical nature of the polymer and fiber is kept constant and the molecular architecture of the polymer is varied. It is found that low Crystallinity polyethylenes are reinforced by keratin fibers but high Crystallinity polyethylenes are not. The keratin fibers inhibit Crystallinity in low Crystallinity polyethylenes but enhance Crystallinity in high Crystallinity polyethylenes. Microscopy shows increased adhesion between the fibers and the polymer for the more amorphous polyethylenes. A model is presented that describes composite properties as a function of fiber properties and matrix Crystallinity.

  • In vivo evaluation of plasma sprayed hydroxyapatite coatings having different Crystallinity.
    Biomaterials, 2004
    Co-Authors: Weichang Xue, Xuebin Zheng, Shunyan Tao, Xuanyong Liu, Chuanxian Ding
    Abstract:

    In this paper, hydroxyapatite (HA) coatings having the crystallinities of 56% and 98% were deposited by the plasma spraying and vapor-flame treatment process. The phase composition and Crystallinity of the coatings were investigated by X-ray diffraction and infrared spectra. The dissolution behavior of the coatings in tris-buffer solutions was examined. The results obtained indicated that the coating having the high Crystallinity showed the lower dissolution as compared to the low Crystallinity coating. The bone bonding ability of HA coatings were observed in vivo by implanted in dog's femur. After 3 months implantation, the high Crystallinity coating showed the higher shear strengths and remained integrated, whereas the separation of the coating fragments was clearly observed in the coating having low Crystallinity.
