The TPNR was prepared by mixing NR （natural rubber） with PE （polyethylene） using 2-roll mills before compressed on cotton fibre spun and vulcanized at 150℃. The mechanical properties and morphology of the membrane were investigated using DMTA （dynamic mechanical thermal analyzer） and SEM （scanning electron microscopy）, respectively. The membrane strength was increased from 10 MPa to 18 MPa after reinforced with cotton fibre spun as well as the increasing of dielectric constant. The membrane was immersed in xylene to remove PE phase before characterization of membrane properties.展开更多

The main product was proved to be BTG. Dyeing substantivity of modified cotton fibre by BTG with disperse dye were improved. The effect of modification conditions, such as the property of alkali and its using amount, curing temperature and time were discussed. Colour yield and resistance to wash fastness were also measured.展开更多
