Plasma treatment, a dry, pollution-free, effective and low cost treatment process, can be used to minimise pilling for wool and cashmere knitwears. By modifying the surface structure of fibres with argon plasma, the pilling grade is significantly improved. An industrial-scale plasma treatment system.....

A new technology for measuring liquid crystal (LC) cell properties is invented. Optical properties and characteristics of LC cells including cell gap, twist angle and rubbing directions of a liquid crystal cell can therefore be measured. They are important parameters for the operation of a liquid .....
