Antibacterial Activity and Thermophysiological Comfort Enhancement by Calcium Chloride Solutions of Highly Elastane Polyamide 66 Fabrics

A novel method to enhance antibacterial activity, thermophysiological comfort properties of highly elastane polyamide 66 fabrics by calcium chloride pad-dry-cure method was proposed. For this purpose, three different calcium chloride solutions were prepared and applied by pad-dry-cure method to the polyamide tricot (locknit) warp knitted fabrics. The effects of this method on polyamide fabrics were investigated by antibacterial activity, thermophysiological properties, physical performance tests and characterization analyses, namely, SEM, EDX and FTIR-ATR. Results indicate that calcium chloride agent procedure significantly affected antibacterial activity and thermal comfort properties. The calcium chloride agent procedure was found to be favorable for polyamide/elastane fabrics since it provided antibacterial activity and thermophysiological effect under mild conditions with good stiffness, handle and whiteness properties by means of calcium chloride ionic bonds onto polyamide/elastane fabrics. Most notably, calcium chloride treated fabrics were evaluated as good antibacterial, extremely breathable and comfortable at a higher level of activity.

Automated summary

A novel method using calcium chloride treatment was proposed to enhance antibacterial activity and thermophysiological comfort properties of highly elastane polyamide 66 fabrics. The results showed that this method significantly improved the antibacterial activity and thermal comfort properties of the fabrics, while maintaining good stiffness, handle and whiteness properties.
