Feel properties, thermal stability and colour combination compatibility of nano-LDH on cotton

Abstract

Abstract In our prior study, we investigated how reactive dyeing of cotton with Mg-Al Layered Double Hydroxide (LDH) nanoparticles improved the fabric's mechanical, UV protection, and flame retardancy capabilities. Low concentration ranges allow for a safer application for wearables, according to characterization and cytotoxic data. To establish industrial applications, it is necessary to look at their objective testing on feel and comfort qualities, thermal stability, and color combination compatibility. In the current inquiry, we experimented with a fabric touch tester (FTT) for the objective evaluation of feel, and then we used a simultaneous thermal analyzer (STA) to examine the thermal stability of treated cotton. In order to ensure commercial use, three sets of Ultra RGB dyes and their mixing were also used, and their dye absorbing capabilities to provide a broad color spectrum were explored. From CIE chromaticity study, it was discovered that they can be used in place of common dyes with a reliable color forecast for dye combinations. The FTT results show that with the addition of LDH nanoparticles to cotton, the fabric's smoothness, softness, and overall PSI steadily decline, but that smoothness is the only significant aspect of overall feel or PSI. LDH was included into the fiber matrix, which boosted thermal stability.
