Abstract
This study examines properties of the cotton/polyamide plain plated commercial socks (CO 81%/PA 19%) and pure polyamide fabric subjected to the multifunctional treatment by a sol-gel coating technique where tetraethyl-orthosilicate (TEOS) and zinc acetate dihydrate (ZAD) were used as precursors. Commercially available sock is produced on a single cylinder sock knitting machine which results in two surfaces (cotton and polyamide), with dissimilar characteristics thus leading to necessity of their separate studies. Experimental part examines surface structural clarification and compound identification using infrared spectroscopy. To assess the impact of modification such properties as air permeability must be tested and analysed. Pilot tests of antibacterial activity against Bacillus subtilis mscL 1141 and Staphylococcus aureus mscL 334 where carried out. Due to the modification consolidation treatment temperature below the destruction of material and the chemical compounds vibrational modes overlap, but in regions 1170–1650 cm−1 and 3200–3395 cm−1 show the presence of bounds corresponding to sol-gel coating presence on the surface.
Highlights
Sock products today must be provided with a range of comfort features such as sweat-absorption, breathability, quick drying, they must be eco and skin-friendly, comfortable, antibacterial and multi-applicable
This study investigates possibilities to evaluate functional coating presence and intensity on the cotton/polyamide plain plated commercial socks subjected to the multifunctional treatment by a sol-gel coating technique via FT-IR ATR spectra and functional properties of modified sock samples
One hundred percent polyamide fabric was exposed to the modification to investigate the effects of the coating on the neat PA excluding the presence of cotton
Summary
Sock products today must be provided with a range of comfort features such as sweat-absorption, breathability, quick drying, they must be eco and skin-friendly, comfortable, antibacterial and multi-applicable. If different types of yarn are used in sock manufacturing, it should ensure comfort and performance.[1] Performing functional modifications in practical applications often address more complex issues. Treating textile fibres and yarns with hybrid organic-inorganic precursors can open possibilities to improve and complement functional and protective properties.[2] As shown in experiments and field research, after such treatments as hydrothermal processing and bleaching, as well as functionalization sock products tend to change their dimensional stability leading to changes in dimensional and comfort properties, that must be considered when designing a new product and its technology.[3]
