The development of composites using carbon fibers as the reinforcement requires surface activated carbon fibers with a durable surface composition. In this work, sized polyacrylonitrile (PAN)-based carbon bers were modi ed by Oxy- Plasma treatment, Oxy- fluorination, and Nitric acid treatment in order to improve the interaction between carbon ber surface and matrix. The effect of different surface treatments was observed by means of contact angle, surface free energy measurement. Surface roughness were seen by the help of Scanning electron microscopy (SEM).The lower contact angle proved the...

Achieving finishing parameters/targets given by the buyers is the most important task of a knitter and dyer of a knitting dyeing industry. All the functions of a knit dyeing industry is centered to achieve the target. If the finishing target is not gained, it is not possible to ship out the goods the destination, as a result a huge loss is supposed to be happened.Practical sound experience is necessary of all the important personnel of a knit dyeing industry. In this book, it has been tried to find out how to achieve the finishing parameters of knit fabrics demanded by buyers. All the steps...
