“…It is necessary to create some functional groups on the polyester polymeric chains. Also, chemical surface modification such as alkali hydrolysis increases the functionality of polyester fibers by introducing hydroxyl and, particularly, carboxylic groups onto the surface of fabric imparting new specifications to the fabric, such as better binding to nano‐TiO 2 particles 40–45…”

Alkali hydrolysis of polyester along with application of nano silver/nano TiO2 to produce hydrolyzed polyester fabric with antibacterial and self‐cleaning properties is a very interesting subject. In this article, a novel idea is introduced to achieve a polyester fabric with self‐cleaning and antibacterial properties with a good feeling handle in one step. The polyester fabric is hydrolyzed in alkali media to enhance the surface activity, improve nanoparticle absorption, and produce ethylene glycol for reducing silver nitrate into nano silver. XRD pattern confirms the presence of nanoparticles with crystal size of 10 nm on the fabric surface and FESEM pictures show the distribution of nanocomposite particles on the fiber surfaces with average size of 54 nm. The degradation of Methylene Blue under daylight irradiation confirms the photoactivity of nano TiO2 on the polyester fabric. Also, very good bactericidal efficiency is obtained against S. aureus and E. coli. Interestingly, the fabric tensile strength improves even with the action of alkali in surface hydrolysis of polyester. © 2013 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013

“…The caustic soda hydrolyzed the polymer chain by generating hydroxyl and carboxyl acid groups. These polar groups attached the nano seeds which are pre-requisite for the growth of nanoparticles [29][30][31]. Due to hydrolysis of chains, oligomers are formed which appear as small particles on the surface of fibers (Figure 2(B)) but no such particles were observed on untreated fabric (Figure 2(A)).…”

In situ deposition of TiO 2 nanoparticles on polyester fabric has been carried out using hydrothermal method by changing the process conditions. The morphology and crystalline structure of as-deposited particles has been studied by using SEM and XRD. The chemical composition of nanoparticles was determined using energy dispersive spectroscopy. The treated sample exhibited photocatalytic solution discoloration and good washing fastness properties. The study of UV protection and moisture management of fabric showed that it had excellent UV protection factor and comfort properties.

“…Fabric used to be treated with high-concentration caustic soda without tension to achieve excellent physical and dyeing properties [11,12]. Mercerisation at high temperature is now a well-established method [13]. e penetration of caustic soda into the bre structure is more rapid [14], which ensures more uniform treatment but less swelling [8].…”

The combined scouring, bleaching and mercerising of single jersey cotton knitted fabrics through the use of high-concentration NaOH was evaluated in this study. The eff ect of that new combined process was compared, contrasted and analysed with pristine scoured, bleached fabric and conventional bleached fabric. Surface morphology, structural analysis and the colour strength of dyed fabrics were examined using a scanning electron microscope (SEM), X-ray diff raction (XRD) and spectrophotometric analysis. The barium activity number and bursting strength of treated fabric was evaluated and analysed in accordance with the relevant AATCC test standards. It was found that a sample treated through combined scouring, bleaching and mercerising demonstrated a higher level of smoothness and lustre than typical scoured and bleached fabric. The treated sample exhibited decreased crystallinity, as well as the transformation of the crystalline phase in a similar manner. The barium activity number, bursting strength and improved K/S value were also in line with the separately mercerised fabric. The above described properties of the combined scoured, bleached and mercerised fabric are sound evidence of the eff ectiveness of the process.
