“…Possible reasons were shown as follows: firstly, pectinase dosage used in this experiment contained the same pectinase activities (assayed with ramie pectin as substrate) and pectinases with bigger ratio of pectinase activity contained less pectinase activities (assayed with apple pectin as substrate). So, pectinase dosages used in this experiment were pectinase C, pectinase D, pectinase A, pectinase E, and pectinase B sorted in descending order and there were more pectinases which could not catalyze the hydrolysis of pectin on cotton fabrics in pectinase with less ratio of pectinase (Saravanan et al, 2009). In addition, dosage of pectinases (the part which could not hydrolyze pectin from desized cotton fabrics) in pectinase with less ratio of pectinase took the majority of components and it attached on the cotton fabrics to block the combination of pectinases (the content which hydrolyzed pectin from cotton fabric effectively) and pectin on desized cotton fabrics.…”

Structural characteristics of pectins from cotton fabrics, ramie, and apple were investigated by titration method and ATR-FTIR spectra. Pectin from cotton fabrics and ramie showed similar structure characteristics, both these two pectins showed big structural difference with pectin from apple. The activities of five pectinases were determined by using these three pectins as substrates. These five pectinases showed similar hydrolysis action on pectin from ramie and cotton fabrics, they also showed a great difference in the hydrolysis of pectin from apple and cotton fabrics. Moreover, bioscouring effect with these five pectinases was investigated, the pectinases with stronger hydrolysis action on ramie pectin displayed better bioscouring effect and the pectinase suitable for bioscouring was selected out. The bioscouring effect of the pectinase selected out was studied and showed almost perfect bioscouring effect.

“…Process of bio-polishing is influenced by concentration of cellulases, temperature, pH, and duration of treatment, besides the activity levels of enzymes, method of mechanical agitations and construction features of fabrics. Bio-polishing makes cotton fabrics look brand new, even if you've washed them several times [23,24]. …”

Enzymes have been used for more than 50 years in the detergent, textile, food industries, to name just a few. In these industries enzymes replace chemicals and minimize water, raw material and energy consumption. Natures own technology provides us with environmentally friendly solutions and better products. Enzymes are the natural solution to industrial problems. With enzymes we can maintain the living standards we have today and at the same time preserve the environment for our children. In textile industry, enzymes are used because: they are accelerating the reactions, act only on specific substrates, operate under mild conditions, are safe and easy to control, can replace harsh chemicals and are biologically degradable [1]. In textile manufacturing the use of enzymes has a long tradition. The enzymatic desizing of cotton with α-amylases is state-of-the-art since many decades'. Moreover, cellulases, pectinases, hemicellulases, lipases and catalases are used in different cotton pre-treatment and finishing processes [2]. These studies will overview the whole clean line of cotton fabrics wet processing arrangement avoiding usage of chemicals and substituting it with enzymes.

“…1 Biopolishing is one of the methods to improve the surface properties of cotton fabrics by minimizing fuzz, pilling and improving lustre of the fabric. 2,3 Cellulase comprises of endoglucanases (EnG), exoglucanases (ExG) and β-glycosidase (BG) which acts synergistically to hydrolyze cellulose by degrading of f β- (1,4) 568 SANKARRAJ and NALLATHAMBI linkages and releases glucose as the end product. 4,5 Cellulose is a linear unbranched polymer and it has highly oriented molecular structure with intermolecular chain bonding.…”

Cellulase treatment on cotton fabric is ecofriendly way of biopolishing. In the present work, biopolishing of cotton fabric using free and immobilized cellulase under various treatment conditions have been carried out using Box-Behnken design and the physical properties like pilling grade, abrasion resistance and flexural rigidity were analyzed. The degradation of cotton fabric minimized and similar results were obtained for pilling and abrasion resistance of free and immobilized cellulase treatment. Higher flexural rigidity is the result of immobilized cellulase treated fabric when compared with the free cellulase. The degradation of amorphous region improves the crystallinity index of the treated samples. This shows that the amorphous region were more prone to enzymatic attack than the crystalline regions. The enzymatic treatment increase the accessible surface area of cotton fibre and it can be measured by Methylene blue absorption value. Methylene blue absorption of the fabric was more for free cellulase than the immobilized cellulase treated fabric. The change in hydrogen bond by the treatment was measured and analyzed by the Attenuated Total Reflectance Fourier-Transform Infrared Spectroscopy (ATR-FTIR).
