“…The imparted anti-UV functionality is governed by the type of substrate, e.g. fabric structure, weight, thickness, open pores [5,35,36], and extent of crosslinking as well as loading of TiO 2 -NPs onto/within the fabric structure. The results in Table 1 signify that the outstanding improvement in UV-shielding capability follows the decreasing order: C/W >V/W, keeping other parameters constant.…”

A green facile nano-finishing route was developed to impart high antibacterial efficacy, UV-protection, self-cleaning and anti-wrinkle functions to cotton/wool and viscose/wool blends using TiO2, and/or Ag-NPs, as active ingredients, along with citric acid and/or succinic acid/ SHP as ester-crosslinking/fixing systems. The data so obtained demonstrated that outstanding durable functional properties can be achieved using the following formulation: TiO2/Ag-NPs (20 g/L each), citric acid/SHP (50 g/L/30 g/L) and the pad- dry microwave fixation at 1300 W for 5 min. SEM and EDX analysis for selected samples as well mode of interactions among the nominated finishing ingredients and the treated substrates were also investigated.

Chitosan and its derivatives can be called environmental purification functional materials as they can effectively control the growth and reproduction of hazardous bacteria and also control toxic pollutants. From the basic science to the latest developments and innovations, starting with the history of the material, this chapter presents a facile way to understand the antibacterial activity of the chitosan, together with other materials, to the reader. This chapter also summarizes the general developments in the study of antimicrobial applications. In the light of the current situation of the research and the progress in the related fields, this chapter discusses the differences among influencing factors in detail and compares the antimicrobial activity between different physical states of chitosan. Also, this chaper discusses the more recent processes and applications.

“…For a given set of finishing conditions, it is clear that: i) among the aforementioned used catalysts, CuSO 4 imparts antimicrobial properties to the finished sample as well as UV-protection properties and these properties are enhanced remarkably in presence of PVP, most probably due to the chelation of the Cu 2+ cations by PVP, ii) the extent of the improvement in these properties follows the descending order: Cu 2+ > Mg 2+ , iii) incorporation of TiO 2 nano particles in the DMDHEU finishing bath, in absence of PVP, enhances the antibacterial and UV blocking properties of the treated fabrics. Incorporation of PVP in the finishing bath enhances the extents of the aforementioned properties which can be explained by the ability of PVP to bind these nano particles via coordination bonds, iv) the differences in the magnitudes of the aforementioned functional properties of treated fabrics are governed by the differences between the aforementioned cations or nano particles in the molecular weight, particle size, location, fixation and extent of distribution, and ability to bind to specific sites in the DNA (19)(20)(21)(22)(23) in the bacterial cells thereby inactivating and killing bacteria as well as in UVblocking and absorbing capacity (24)(25)(26)(27) and v) the inactivation efficiency of E. coli (G -Ve bacteria) was lower than that of S.…”

O IMPROVE the resiliency as well as to functionalize linen ……..fabric to resist S. aureus and E. coli bacteria and block UV-B radiation, PVP was incorporated into easy care finishing formulations to chelate the TiO 2 nano-particles and Cupper sulphate as a catalyst. Factors affecting the crosslinking process were studied. The obtained results indicate that:• the easy care finishing of linen fabric using DMDHEU, 50-75 g/l, as a crosslinker enhances the nitrogen content, resiliency and yellowness along with decreasing the tensile strength as well as the wettability of the treated fabrics, • incorporation of 4% PVP in the easy care finishing formulation of linen fabrics in presence of 50 g/l DMDHEU, enhances the nitrogen content, tensile strength and yellowness along with a decrease in the resiliency as well as the wettability of the treated fabrics, • esterification of linen fabrics with CA or BTCA in presence of 4% PVP is accompanied by an enhancement in the nitrogen content as well as tensile strength along with a decrease in the resiliency, wettability and yellowness of the treated fabrics, • incorporation of CuSO 4 as a catalyst or TiO 2 nano particles in the DMDHEU finishing baths in the presence of PVP enhances the extents of the antibacterial as well as the UV blocking properties of the treated fabrics, • the functionalized linen fabric samples are durable up to 10 washing cycles with little drops in their functionalities.Flax is used to produce woven and knitted fabrics with exceptional health, hygienic and aesthetic qualities. The principal physical characteristics of flax which are related to its application as textiles are rapid absorption and desorption of moisture, good conducting of heat leading to the cool handling and un-collection for the electrostatic charges, that is to say linen is beneficial for the human health as it provides comfort (1,2) .Besides, the high crystallinity of the cellulosic component of the flax fiber results in high creasability of linen fabrics, low extensibility of flax yarns, high
