AB  - Commercial P25 TiO2 nanoparticles are widely exploited as an efficient photocatalyst. In the textile domain, these nanoparticles are used for the production of self-cleaning, highly UV protective textiles, with an antimicrobial activity. The disposed textile products may end up in a landfill where they are subjected to the biodegradation process. Considering the importance of the later, this study discusses the biodegradation behaviour of cotton fabric impregnated with commercial P25 TiO2 nanoparticles. Photocatalytic activity of TiO2 nanoparticles immobilized on cotton fabric was proved by the photodegradation of dyes C. I. Acid Orange 7 and methylene blue in aqueous solution. Biodegradation of fabrics was assessed by soil burial test in periods of 3, 9 and 18 days. Chemical and morphological changes induced by biodegradation were analyzed by FTIR, SEM and EDS. A colour of the samples gradually changed from white to yellow/brown due to rotting. SEM analysis revealed a severe destruction of the control and impregnated cotton fibres after 18 days of soil burial which was in line with visual appearance of completely damaged fabrics. The results confirmed that biodegradation behaviour of both the control and impregnated sample was equivalent, indicating that P25 TiO2 nanoparticles did not inhibit the biodegradation process of cellulose.

AB  - This study discusses the effect of corona pre-treatment at atmospheric pressure and subsequent loading of colloidal TiO2 nanoparticles on the biodegradation behavior of cotton fabric. Biodegradation performance of the control and finished samples was evaluated by standard soil burial tests in predetermined periods of 3, 9 and 18 days. Color and breaking strength measurements were utilized for assessment of biodegradation progress. Morphological and chemical changes induced by biodegradation were analysed by SEM and FT-IR analyses, respectively. Colorimetric, morphological and chemical changes induced by the biodegradation process were slightly less prominent on corona pre-treated cotton fabric impregnated with TiO2 nanoparticles compared to corona treated and control cotton fabric. Although the breaking strength of all samples significantly decreased after 18 days of soil burial, this decline was the least evident on the sample impregnated with TiO2 nanoparticles. However, taking into account the extent of these differences, the influence of TiO2 nanoparticles on biodegradation rate of cotton fabric, which underwent a combined treatment corona/impregnation with TiO2 nanoparticles, could be considered as insignificant. These results confirm that chemical modification of cotton fabrics with plasma and subsequent loading of TiO2 still maintained sustainability of cellulose fibres.

AB  - In this paper, the temperature responsiveness (swelling/de-swelling) of the poly-NiPAAm/chitosan (PNCS) microgel applied to a PBS fabric in combination with two different matrixes, i.e., 1,2,3,4-butanetetracarboxylic acid (BTCA) or vinyltrimethoxysilane (VTMS) with hydrophilic fumed-silica nanoparticles (SiO2) was studied. While a BTCA-based matrix enables chemical bonding of the PNCS microgel particles, resulting in a formation of a rigid surface-modified system, a VTMS/SiO2 polysiloxane matrix has the ability to physically entrap the PNCS microgel particles and stimulate, due to its elasticity, a formation of a more flexible coating on the surface of PES fibres. Morphological and chemical properties of differently finished samples were studied with the SEM and XPS analyses. To determine the swelling/de-swelling ability of the PNCS microgel, the moisture contents of the samples, before and after five repetitive washings, were obtained for the samples conditioned at two different temperatures, i.e., at 25 degrees C and 40 degrees C, when the PNCS hydrogel was in its swollen or collapsed phase. The results showed that the rigid structure of the BTCA-based matrix restricted the swelling ability of the microgel particles, resulting in a 12 % lower moisture content of the corresponding sample in comparison to the moisture content determined for the sample with the PNCS microgel particles physically entrapped within the polysiloxane matrix. Due to its elasticity, the polysiloxane matrix enables the microgel particles to fully expand, which is the consequence of a partial removal of the PNCS microparticles during the washing procedure.

AB  - An innovative strategy for functional finishing of cotton involves application of stimuli-responsive surface modifying system based on temperature- and pH-responsive poly-NiPAAm/chitosan microgel. The stimuli-responsiveness implied to cotton is the consequence of swelling/collapse of the microgel particles incorporated to the fibre surface, which produces an active liquid management system. The performance of functionalized cotton fabric in terms of liquid management properties was assessed by choosing appropriate techniques (water uptake; thin-layer wicking; water retention capacity; and drying capability) and discussion of the results was based on the types of water that are expected to be present in hydrated cotton and stimuli-responsive microgel.

AB  - The possibility of incorporating a stimuli-responsive microgel into a silica matrix by the sol-gel method was studied. This method allows the preparation of a novel class of functional finishes for textile material modification, which is aimed at the creation of simultaneous stimulus-responsive behaviour and functional protective properties. Using a pad-dry-cure method, a thermo-and pH-responsive microgel (PNCS) based on poly-(N-isopropylacrylamide) (poly-NiPAAm) and chitosan was embedded into a silica matrix on a previously activated polyester (PES) fabric. The matrix was composed of a model sol-gel precursor, vinyltrimethoxysilane (VTMS), in combination with hydrophilic fumed silica nanoparticles (SiO2). Functionalized PES fabric samples were characterised by determining the morphological and chemical properties using scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR) and X-ray photoelectron spectroscopy (XPS). The stimuli (temperature and pH) responsiveness of the functionalized PES fabric was established by measuring its porosity, wicking ability, moisture content, drying rate, water vapour transmission rate and water uptake. In order to assess the washing fastness of the surface modifying systems, the tests were done before and after five consecutive washings. The results showed that sol-gel technology is an appropriate method for the incorporation of PNCS microgel on PES fibre surface. Because of the elasticity of the sol-gel matrix, the VTMS/SiO2 polysiloxane film had no adverse influence on the swelling/deswelling effect of the PNCS microgel, thus retaining and even enhancing its stimulus response.
