Study on the Impact of Dye - Sublimation Printing on the Effectiveness of Underwear.

Glombikova, Viera; Komarkova, Petra

This study deals with the effect of dye-sublimation printing on the performance of underwear. Two groups of polyester knitted fabrics were analysed. The change of tree selected groups of properties was investigated before and after the application of dye-sublimation printing, namely durability (breaking force and elongation, abrasion resistance and pilling resistance), physiological properties (water vapour permeability, air permeability) and colour-fastness (resistance to rubbing, to domestic and commercial laundering, to perspiration). Further, the structure changes of fabrics (thickness and density) during heat pressing both without application of dyes (without transfer printing on material) and with application of dyes were also studied to analyse the affect extent of printing conditions (particularly pressure and temperature) on total wear comfort printed fabrics. The results show that the tested materials meet requirements in terms of colour-fastness to rubbing, to domestic and commercial laundering and to perspiration to a very high standard (grade 5). In terms of abrasion resistance and pilling resistance the material also showed high resistance. The air permeability for both fabrics decreased by about 40% in comparison with the value obtained before printing and the mechanical properties slightly increased (about 8%). This was due to an increase in the stitch density and a decrease in the thickness, therefore reducing the porosity of the material for printing conditions, mainly due to the influence of the pressure and temperature within the heat press machine.
