Lyocell Fiber

Regenerated cellulose fiber is the most widely-used and most variety of cellulose fiber. Five categories and ten kinds of fibers such as lyocell fiber, modal fiber, bamboo pulp fiber, sheng-bast fiber, Outlast viscose fiber were chosen as the research object. The strength property and elasticity of fibers in dry and wet state were tested and analysis. The comprehensive performances of fabrics were studied and mechanical properties of the fibers were listed in the order from good to bad by grey clustering analysis. The results show lyocell G100 and lyocell LF have better comprehensive mechanical properties ,while other new regenerated cellulose fibers’ comprehensive mechanical properties are general. Among these fibers modal fiber’s comprehensive mechanical properties are slightly better than sheng-bast fibers’ and bamboo pulp fibers’. Modal fiber, sheng-bast fiber and Bamboo pulp fiber have no significantly poor single parameter and all of them have better comprehensive mechanical properties than various viscose fibers. Outlast viscose in which has been added phase change materials sensitive to temperature by Microcapsule techniques fundamentally keeps similar comprehensive mechanical properties with other regenerated cellulose fibers,but its properties decline slightly .

Polyaniline (PANI) nanotubes were synthesized separately using amino acetic acid (AA), ethylenediamine tetraacetic acid (EDTA), oxalic acid (OA) as dopant and ammonium persulfate (APS) as oxidant by a self-assembly method. SEM, TEM,FTIR and X-ray diffraction (XRD) and applying the 4 probes method characterized the morphology, structure and property of the product. It was found that nanotubes morphology were synthesized when the [Aci/[A ratio is 1:2.The room template conductivity of the products were studied.

Abstract To prepare antibacterial fabrics with simple approach, wood pulp/viscose fibers and amino-capped silver nanoparticles (Ag NPs) solution were utilized to form Ag Nps-coated wetlace nonwove fabric. Characterization of the Ag Nps and prepared wetlace nonwoven fabric was performed in virtue of TEM, UV-vis, XRD, ICP-AES, FESEM, EDS mapping and antibacterial test. FESEM and EDS characterizations demonstrated the hierarchical and uniform coating of high-density Ag NPs on wood pulp fibers, and antibacterial test indicated the excellent antibacterial activity of prepared wetlace nonwoven fabric.

Bamboo Pulp Fabric

Bamboo pulp fibers, made of fast grown bamboo, were the recycled and environment-friendly natural raw materials in the textile industry which particularly today was paid more attention to its good performance due to energy and environment crisis. Hyper branched polymer was attracted more study because of the vast potential application in the future. In this study, the fabrics were modified with the amino-terminated hyper branched polymer (HBP-NH2) by dipping method and anti-UV and anti-bacterial properties of the treated bamboo pulp fabric were investigated. The results showed that the treated bamboo fabric had good antibacterial properties, the bacteria reduction of S.aureus and E.coli were as high as 89% or more, and also remained at around 88% after 20 times washing. The UPF values were increased from 8.16 to 18.18 which improved the anti-UV property of bamboo fabric.

The structure and property of Ce-doped Ba0.2Sr0.8TiO3 (BST) were investigated as a function of Ce content. The density experiment results confirmed that increasing the Ce doping ratio caused the decrease in shrinkage factor of BST in the sintering procedure. Additionally, both Scanning Electron Microscope (SEM) and X-ray diffraction (XRD) analysis showed that the grain size of Ce-doped BST was dependent on the Ce content. Further more, the dielectric constant and dielectric loss had a curve relationship with increasing Ce content. The improvement of the electrical properties of Ce doping BST may be related to the decrease in the concentration of oxygen vacancies. According to the research, the diameter of grain, the dielectric constant and loss factor of the 1mol% Ce-doped Ba0.2Sr0.8TiO3 were 500nm, 365.8 and 0.0063, respectively.

The PbO2 film electrodes have been prepared by different electrodeposition process onto aluminum substrate.The electrochemical activity of the electrode for oxygen evolution reaction in 50g•L-1Zn2++150g•L-1H2SO4 solutions have been studied. The results show that the best activity of the electrodes obtained A1/conductive coating was electrodepositing PbO2 in alkaline lead solutions firstly, then plating PbO2 in acidic lead nitrate solutions. This can be attributed to the conductivity of the substrate, the crystal phase structure and property of PbO2. SEM-EDX analysis shows the beta-form, deposited from acidic solutions of Pb(II), has a distorted rutite structure, and the alpha-form, deposited from alkaline solutions, has the spherical cell. The high non- stoichiometry of PbO2 was obtained in alkaline lead solutions.
