Protein fibers have superior physical properties in comparison to other textile fibers. Despite of their ideal properties, as far as fiber dimensions and morphology are concerned, protein fibers not only are expensive, but also are non-uniform. Scale on the surface of wool as the most renowned protein fiber adversely affect various wool processing operations. In contrast to silk or wool, fibers re-generated from soya beans benefits from uniform dimensions. Considering the rising cost of chemical fibers as the direct result of soaring crude oil prices in recent years, due to low cost of soya fiber, the use of this fiber has been rapidly increased. In addition to general defined physical properties, soya fibers have other unique properties such as brightness, natural smoothness and good dyeability. Fabrics and apparels made from soya fiber exhibit excellent drape and comfort. On the other hand the cream natural colour which hindrances dyeing of light shades, reduced tensile strength in wet condition, and sensitivity during bleaching process is the undesirable disadvantages associated with soya fibers. These draw back can hinder full commercial exploitation of soya fibers. In this research soya fibers were processed, using novel and conventional exhaustion and pad-steam bleaching. The novel bleaching process comprised pad-ozone, pad-microwave irradiation and pad-UV irradiation methods. The novel methods employed for the first time in this research, unlike conventional bleaching methods not only are more environmental friendly, but also are more economical as far as water consumption or post process pollution treatment is concerned. Acquired data of the novel methods were compared with those obtained from conventional bleaching method. It was found that, while reduction in yellowness index, using exhaustion and pad-steam were 31% and 26% respectively, sample bleached by ozone yielded 57% reduction in yellowness index. Bleaching using pad-ozone method increased the whiteness index of commercially available soya fibers bleached by 76%. The results indicate that there is direct relation between pH, exposure time to ozone and obtained whiteness index. The achieved whiteness index using pad-UV irradiation and pad-microwave irradiation was not tangible 21% and 12% reduction in yellowness index, respectively. Apparels in addition to manifested properties such as aesthetic and comfort, nowadays must have self cleaning, flame retardant, anti odor and antimicrobial abilities. Extensive researches have been conducted on imparting anti microbial property to textile fabrics using silver nano particles. However, incorporation of nano silver is thought to be hazardous to human.
