New Techniques in Cotton Finishing

Abstract

The aim of this study is to investigate the effects of new advanced processes (ultrasound, ozonation, and ultraviolet) on cotton woven fabric's hydrophility and polymerization degrees, breaking strengths, whiteness, and desizing degrees. For this purpose, all trials were realized with water at 63-65°C by the aid of advanced processes. At the end of the experiments, it was noticed that advanced processes can be used in pretreatment of cotton fabrics. Ultrasonic treatment followed by ozonation gives sufficient whiteness degrees and hydrophilily values to the fabric. At the same time, treatment of cotton fabrics with new processes provides savings of thermal energy, water, and chemicals. Moreover, these processes are considered as green processes because they are ecological in certain conditions when compared with conventional processes.

Effects of ultrasonic laundering on the properties of silk fabrics

“…8,9 Over the past 20 years, considerable efforts have been made in introducing ultrasonic energy to different textile wet processing operations, especially in the field of bio-processing of fabrics. Ultrasonic agitation of processing solutions has been found to improve the productivity and/or effects of these treatments, including enzymatic desizing, 10 scouring 11 and bleaching 12,13 of cotton fabrics, enzymatic degumming of silk fabrics, 14 scouring 15,16 and bleaching 17 of raw wool fiber, as well as dyeing [18][19][20][21] and finishing 22 for a variety of fabrics. Ultrasonic extraction procedures show considerable superiority over conventional methods for constituent analysis of the substances or chemicals on fibers or textiles, such as multiple elements on cotton fibers, 23 resinous binders on an historic textile 24 and formaldehyde residue on textiles.…”

Use of Ozone in the Textile Industry

“…Ozone must be generated "in situ" because it is very reactive gas and cannot be stored and transported to anywhere. So, it has to be generated [3]. The basic methods for generating ozone artificially are below [5-7, 9, 12-15]:…”

“…The combination of ozone and ultraviolet processes for high whiteness of the fabric is recommended. However, breaking strengths and hydrophilicity values have to be considered carefully [3].…”

“…Ecological problems are commonly related with water contamination in the textile dyeing and finishing industry. Wastewater of the textile industry is hot, has strong odor, and colored by dyestuffs, which are used as a part of dyeing and/or printing process [2][3][4].…”

A Research of Applicability of Ozone Bleaching Process for the 100% Cotton Fabrics at Jigger Machine

“…Besides, it self-decomposed in an aqueous solution to form hydroxyl free radicals which have stronger oxidizing ability. Therefore, ozone has been widely accepted as a forceful disinfectant and a chemical oxidant [14][15][16][17]21]. It has been used as an eco-friendly alternative process in order to prevent environmental pollution in many To cite this article: Paksoy N, Balcı O, Sancar Beşen B.…”
