In this project, the possibility of replacement of chlorination with potassium permanganate was investigated. As a new method KmnO 4 was applied in saturated sodium chloride solution in order to limit the process effects to the fiber surface. In the first step, the optimum concentration of the potassium permanganate and sodium bisulphite were obtained. In the recent decades,using of irradiation treatments specially for surface modification of textiles has been investigated because the replacement of wet-finishing with low or zero-effluent processes is now a priority for the textile industry. Therefore, in this work,using of microwave irradiation in the shrinkproofing treatmrnt of wool fabrics was also studied. Subsequently, fabrics were padded in the potassium permanganate and sodium chloride solution and then were exposed in the domestic microwave oven. Furthermore, Dry treatments being clearly more enviromental friendly. Therefore, the possible fiber surface oxidation with KmnO 4 powder under microwave irradiation was considered. In addition, the combination of Siroflash method with microwave irradiation and replacement of hydrogen peroxide with KmnO 4 in this method was investigated. Another shrinkproofing technique was applied using UV irradiation without oxidative agents. By these methods the resistence of wool fabric to felting is %79.5 better than untreated fabric. Also the reduction of tensile strength is lower than %20 respect to the untreated fabric which is similar to the amount of soluability in alkaline solution. Whiteness and yellowness index and wettability of wool fabrics were better than untreated sample. In conclusion, results showed that by use of these methods, the shrinkage of fabric was desirable while the amount of damage of wool fabrics was acceptable. The other fiber which was investigated is polypropyene. This fiber is one of the polyolefins. This type of polymers exhibit the twin benefit of ease of processing and also possess excellent physical and chemical properties. However they have inert surfaces and so surface modification generally recommended to combine the effects of both the original bulk property with the newly designed surface property. Therefore, in this study The oxidation of polypropylene fabrics in an aqueous solution in the presence of potassium permanganate was carried out using microwave irradiation. The oxidation was investigated at intervals times of 30, 60 and 120 s. Data available from the ATR spectroscopy showed the vinilyc, carbonyl and unsaturated groups due to oxidation on the surface of polypropylene fabrics. Furthermore, anti-static tests and moisture regain measurements confirmed that the anti static propensity of oxidized fabrics has been increased and the hydrophilic tendency of them has been improved, too.
