Investigations on Moisture Transmission Characteristics of Blended Single Jersey Fabrics

摘要

Moisture transmission properties of some combinations of polyester and viscose blended single jersey fabrics were studied in an effort to understand the physical basis of clothing comfort. In addition to this an attempt has also been made to investigate the influence of enzyme treatment on moisture transmission characteristics of P/V blended single jersey fabrics. Polyester and viscose staple fibers of different deniers were ring spun with various blend proportions, which were knitted into single jersey fabrics. These fabrics were dyed and then treated with Lipase enzymes. Commercially available enzymes and enzymes cultured in the laboratory were compared for their activity of surface modification of polyester fibers. The fabrics were tested for their Liquid Moisture Transmission characteristic, expressed in terms of its wickability and Moisture Vapour Transmission which is expressed in terms of Relative Water Vapour Permeability % in grey, dyed and enzyme treated stages. From the results, it can be observed that the liquid moisture transmission of P/V-80/20 combinations has been improved well. The results indicate that the liquid moisture transmission is strongly influenced by the enzymatic treatments. This is mainly due to molecular re-orientation in the surface characteristics of polyester fiber component in the fabrics. A slight improvement in terms of moisture vapor transmission has been observed in all the fibre denier combinations, blend proportions and enzyme treated fabrics.
