Major factors affecting fixation of PVP onto cotton fabrics were studied. These include APS as well as PVP concentrations, time, and temperature. Furthermore, PVP was incorporated in the easy care finishing of cotton fabrics with DMDHEU utilizing APS to serve as catalyst in both the fixation of PVP as well as finishing of cotton fabrics. Results indicated that cotton fabrics treated with 6% PVP and 1.5% APS followed by heating at 90°C for 30 minutes were partially crosslinked with better performance properties and dyeability. Additionally, the post-treating of PVP-finished fabrics with silver nitrate aqueous solution imparts antibacterial activity. Increasing the PVP and/or resin concentrations enhance the antibacterial properties of the treated fabrics. Furthermore, characterization of crosslinked PVP was performed by investigating the infrared, thermal gravimetric analysis, and scanning electron microscope of treated cotton fabrics.

The results show that Non—woven insulating materials exhibit high thermal resistance in dry contact method under moderate wind velocity, whereas the thermal resistance values measured under wet conditions is significantly lower. The effect of air layer thickness, permeability and other important parameters, such as porosity, surface area have also been considered and correlated to assess the overall performance of protective clothing ensemble.

The purified adduct has a melting point of 67°C, and its FTIR spectrum was investigated. An aqueous emulsion containing the adduct (105 g/kg), stearic acid (45 g/kg), and TEA (24 g/kg) acquired 100% cotton fabric water/oil repellency when padded in a bath containing different concentration (20—50 g/L) of the emulsion and dried at 100°C per 3 minutes. Raising drying temperature (100—180°C) enhanced water/oil repellency. The so-treated fabric lost water/oil repellency after five washes. Addition of DMDHEU to the padding bath relatively improved water/oil repellency up to the 10th wash, but it was completely lost after the 25th wash. It was concluded that the adduct is mechanically entrapped within the crosslinker/fabric network and it escapes this entrapment during repeated laundering.

Wetting, wicking, and moisture vapor transmission (MVT) properties are the critical aspects for evaluating the comfort performance of textiles. In this study, the effect of stitch length and knit structure on comfort characteristics of moisture management finished knitted fabric that includes wicking, wetting, water absorbency, MVT, and air permeability have been analyzed.

With increase in number of coatings, the resistivity of the fabric decreases. The plain woven fabric gives higher surface resistivity than twill and satin weaves. Shear rigidity of twill and satin fabrics are lower than that of plain woven fabrics.
