Ozone, composed of three atoms oxygen, can be used to oxidize many inorganic and organic impurities. Because its high oxidizing capacity, the opportunities parameters ozone gas use in bleaching cotton fabrics were researched this study. It was found that a very short time bleached if water content cotton-woven fabric 60% pH impregnated 7. Moreover, ozonation at room temperature shown more efficient than medium temperatures.

Abstract Because the waste production is inevitable in almost all industries, elimination of these wastes a requirement terms environmental regulations and welfare creatures future. In this study, use pumice stones denim washing mill intended to eliminate pollutant by material obtain economic benefits converting it adsorbent. The pollutants effluents obtained from three different localisations water treatment system same factory were removed through adsorption. experimental studies carried...

The aim of this study is to investigate the effects new advanced processes (ultrasound, ozonation, and ultraviolet) on cotton woven fabric's hydrophility polymerization degrees, breaking strengths, whiteness, desizing degrees. For purpose, all trials were realized with water at 63-65°C by aid processes. At end experiments, it was noticed that can be used in pretreatment fabrics. Ultrasonic treatment followed ozonation gives sufficient whiteness degrees hydrophilily values fabric. same time,...

Abstract The aim of this study was to investigate the effects novel treatment techniques (ozone and ultrasound) on dyeability Angora rabbit fiber. For purpose, ozonation time fiber moisture during dyeing properties were researched. Also, performed conventionally with use ultrasound after ozonation; these compared in terms color yields. Consequently, it found that process power improved significantly. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci,

It is well known that ozone can be used as a bleaching agent for cellulosic textile materials. In the context of this study, investigations were undertaken to optimize linen fabrics using Box-Behnken Experimental Design. The process involved two distinct steps where ozonated under different treatment times then latter in subsequent step subjected hydrogen peroxide variety conditions. As result three optimum recipes achieved and pretreatment with 15 min before supplies time chemical savings.

This article is about bleaching of soybean fibers. Although the studies related to dyeing fibers have been found in literature, little has reported on effect bleaching. The natural color protein pale yellow or cream, and it therefore usually necessary bleach them improve their whiteness. Different treatments combined with ozonation were performed order establish whiteness, yellowness, lightness, wettability, hydrophility, moisture sorption, fiber damage properties knitted fabric. As a result...

This paper provides a general framework for studying the yellowing tendency of ozonated cotton fabric. Yellowing fabric and ways to prevent this situation was examined extensively. For purpose, five different treatments (hot/cold rinsing, washing, reductive catalase treatment) were performed after ozonation. It found that performing any kind treatment significantly important preventing during storage.

In this study, ozonation as an environmentally friendly bleaching method was studied for decolorization of leather products. The effect time (3, 5, 10, 15 and 30 min) water pick-up value (WPV) (0%, 20%, 40%, 60%, 80% 100%) were investigated on effect. For aim, the color measurement tensile strength tests performed, also structural changes determined by scanning electron microscope (SEM) Fourier transform infrared spectroscopy (FTIR) after process. results measurements showed that min 60% WPV...

Carpets are widely used in living spaces for beautiful appearance, heat, and sound insulation. Cleaning carpets is essential both their lifespan health hygiene. Washing operations carried out at regular intervals carpet-washing factories. Industrial carpet washing must be done consciously because a significant amount of water time consumed during these processes. In addition, problems such as discoloration strength losses may encountered delicate carpets. this study, stained were washed...

The bleaching of greige soybean knitted fabric using ultraviolet (UV) irradiation on hydrogen peroxide impregnated samples was studied. effect many variables the samples’ whiteness, lightness, wettability, hydrophilic properties, cystine content, surface examination, and Fourier transform infrared (FTIR) properties investigated. UV/H2O2 process optimized a Box-Behnken experimental design three optimal recipes were achieved. A novel for fabric, which consists sample impregnation in various...
