In order to obtain textile materials with potential utility in the development of cosmetic textiles, this study examined the deposition by padding of rose and sage microcapsules on woven textile structures, with different fiber compositions (100% cotton and 50% cotton/50% polyester). Cationization of the textile materials was performed to enhance the degree of uptake the pf the microcapsules on the fabrics’ surface. A commercially acrylate-based binder was used to fix the microcapsules to the textile substrate and to improve the durability against external factors. The finished textile materials were characterized in terms of their physical-mechanical characteristics. The distribution of microcapsules on the fabrics surface before and after five washing cycles and 1000 abrasion cycles was investigated by scanning electron microscopy. The biocompatibility in terms of cell viability, cell membrane integrity and inflammation status of the functionalized fabrics was evaluated on CCD-1070Sk normal human dermal fibroblasts. The cell morphology was evaluated by F-actin staining using fluorescence microscopy and no significant changes were noticed after the incubation in the presence of fabrics compared with control. The in vitro biocompatibility evaluation on human skin cells confirmed the absence of cytotoxicity after the short-term exposure, supporting further in vivo use of these innovative textiles with improved properties.

In order to obtain the textile materials with potential for use in the treatment of inflammatory skin conditions, this study approached the laboratory experiments related to depositing by padding of oil-in-water emulsions type based on chitosan-propolis-cinnamon essential oil. In this regard, seven experimental variants of emulsions were prepared and then characterized by specific methods from physical-chemical and stability point of view. The chitosan-propolis- cinnamon essential oil-based emulsions were then immobilized on a knitted textile structure from 100% organic cotton. The functionalized textile materials were characterized from morphological and antibacterial activity point of view. pH values obtained for the synthesized polymeric systems were in the range 4.67–4.88 and electrical conductivity of the emulsions increases with the concentration of the hydrophilic phase in the system, the highest values were registered for the emulsion code R4CSP developed with the smallest volume fraction of water. The stability index over a period of 10 days indicated that emulsions are stable, not showing the presence of one of the flocculation, creaming / sedimentation, coalescence or Ostwald ripening phenomena. The highest values of emulsifying activity index were obtained for the R7CSP, emulsion developed with the smallest volume fraction of water. The highest value of viscosity was obtained for the experimental variant R4CSP in which the highest volume fraction of chitosan and the smallest volume fraction of water were used. The textile materials treated with synthesized emulsions based on chitosan- propolis-cinnamon essential oil have antibacterial effect against the S. aureus test strain, with inhibition zones between 1.5 mm (R2CSP and R7CSP) and 4 mm (R6CSP).

The objective of this study was to develop a naturally dyeing process of 70% wool /30% Angora mohair blended yarns by using bio-mordants as an environmentally friendly alternative for the conventional metallic salts. Bio-mordanting operation was achieved by using of condensed tannin extract from quebracho bark trees. Conventional mordanting has been performed using the conventional mordants like copper sulphate and tin chloride. Another specific objective of this study was to investigate the possibility of application of pre-irradiation treatment in natural dyeing in order to improve the tinctorial affinity of blended yarns. Prior to natural dyeing the blended yarns were subjected to irradiation treatments using an industrial gamma irradiator of type SVST Co-60/B, the minimum irradiation doses accumulated by the blended yarns were about 18 kGy and 28 kGy. To show the influence of gamma pre-irradiation on natural dyeing behavior of blended yarns the spectrophotometric measurements were performed by evaluating the color difference attributes and color strength. Color fastness to washing, light, acid and alkaline perspiration were evaluated in order to establish the effectiveness of gamma treatments and mordanting operation (conventional mordanting or bio-mordanting) on natural dyeing. The blended yarns were also analyzed in terms of their main physicalmechanical and physical-chemical characteristics. Scanning electron microscopy and Infrared spectroscopy were used to monitor surface modifications, chemical and conformational changes in proteinic fibers induced by the applied treatments.

This study presents a strategy to obtain textile materials with hydrophobic/oleophobic effect by applying hybrid coatings based on a mixture of flower-like ZnO nanoparticles and organically modified SiO2 nanoparticles (ORMOSIL). The obtained dispersions based on both types of nanoparticles are stable, with unimodal distribution of smaller quasi spherical shape and average size of 158 nm for SiO2 nanoparticles and respectively, with bimodal distribution with a broad distribution of particle size and average size of 144 nm and 435 nm for ZnO flower-like nanoparticles. The ZnO/SiO2 NPs based dispersions were then applied on 100% cotton fabrics on a laboratory scale by padding method in two successive phases. The functionalized cotton fabrics were evaluated in terms of surface morphology changes, whiteness degree and water and oils repellent properties. The developed textile materials exhibited a low wetting capacity, with high values of water absorption time (>15 minutes) and a water-repellent degree of 75 (AATCC photographic scale) and 2.5 respectively (ISO scale) showing an acceptable hydrophobic effect. The functionalization treatment based on mixture of ZnO/SiO2 nanoparticles led to obtaining an efficient cotton substrate for the rejection and protection against the oily substances which exhibit an oil repellency degree of 6. Also, the functionalization treatments did not significantly change the surface morphology of the fibres, suggesting that the bulk properties of the cotton fibres remained undamaged.
