"Chemical Characterization and Thermal Comfort Properties of Cotton Finished With Phase Change Materials and Antimicrobial Agents"

Abstract

The expectations regarding the functional characteristics and performance of textile products have been steadily increasing. In this sense, multifunctional materials with thermoregulatory and antimicrobial properties were developed using different finishing strategies. For this purpose, through finishing processes, the application of microcapsules of phase change materials, mPCM, combined with different antimicrobial agents of natural origin, was carried out. Specifically, zeolites doped with silver, composites of chitosan with zeolites doped with silver, and TiO 2 , in different application combinations, were used. The resulting multifunctional cotton materials were characterized and their performance was evaluated in terms of thermal comfort, stationary properties and moisture management. The statistical analysis of the results has indicated that the thermal properties underwent changes related to the introduction of mPCM in the treated samples, but the antimicrobial finishing also had an effect on the results obtained. As expected, the finishes contributed to a decrease in the permeability of the samples studied, however, without compromising the breathability of the materials. It was concluded that the best combination of finishes was achieved with the application of mPCM combined with the chitosan film with silver doped zeolites.

Effects of Repeated Laundering on Thermal Comfort Properties of Cellulosic Knitted Fabrics

“…A proportional trend may be seen for the thermal resistance of the fabrics, namely, that increasing the number of laundering cycles increased the thickness and decreased the air permeability of fabrics up to a certain value and further increasing the number of launderings decreased the thickness and increased the air permeability, which slightly decreased the thermal resistance of the fabrics, in general. Although there is not a specific study investigating the thermal behaviour of natural and man-made cellulosic fibres upon repeated laundering, in the literature, according to the study of S. Kim et al 17 the thermal insulation properties of polyester filled sportswear fabrics increased by increasing the number of laundering cycles up to 5 cycles and decreased smoothly after this point to 10 cycles. According to Nayak et al, the thermal resistance of aramid fabrics increases by increasing the number of laundering cycles.…”

Thermal and breathability management of microencapsulated phase change material (MPCM) incorporated jute fabric

“…Numerous studies have been conducted on the synthesis, application, and characterization of PCMs treated fabric using different methods to impart thermoregulation properties. Scacchetti and Soares 14 concluded the best combination of MPCM with the chitosan film containing silver doped zeolites. Sanchez et al 15 synthesized polystyrene microcapsules containing paraffin wax.…”
