A comparative analysis with knitted fabrics from conventional ring-spun, siro-spun and compact yarns has also been made to assess its suitability. It is observed that polyester and cotton fabrics made from Eli-Twist yarn show very good permeability and moisture management characteristics.

The effect of different loop lengths and the impact of oxygen plasma treatment on the moisture management properties of the fabric has also been studied. The moisture management properties are better for the plasma-treated fabric and also for the fabric having highest loop length. The moisture management properties of the fabric have been improved with the oxygen plasma treatment.

PTFE coated and without coated media. The materials have been assessed using flyash aerosol under varying time intervals (6, 9 and 12 min) at different inlet dust densities (50, 90 and 150 g/m3). The flyash particles are charged prior to their deposition over the filter media using a three phase parallel plate box pre-charger at two different levels of pre-charge, viz. 4 kV and 8 kV along with 0 kV. Results reveal that the filtration performance for PTFE coated material is better under all conditions. However, an enhanced filtration performance in terms of particle emission and pressure drop is noted at increased pre-charge level and higher cyclic interval. It may also be noted that the level of improvement in filtration behavior for both the materials has been better at initial level of pre-charge from 0 kV to 4 kV. However, the cumulative behavior of all the factors is also found significant.

Fabric dimension (lengthwise and widthwise), fabric areal density and fabric tension decay are taken as response variables. The findings establish that the optimum heat-setting parameters are 190℃ temperature, 75s process time and 13.5% width extension. It is necessary to optimise the heat-setting parameters to achieve better fabric dimensional stability, as overheating damages and deteriorates some of the elastane filaments, resulting in reduced recovery properties after a certain temperature point.
