Among the various man-made regenerated cellulosic fibres, modal has achieved a prominent place. Fabrics woven from viscose fibres have always been a fashion designer's delight, due to their excellent drape, lustre, softness, absorbency and colour brilliance. But the technology for chemical processing of modal-based fabrics is not well established at the shop floor. In our preliminary study of the processing of modal fabrics by conventional techniques, including the tapela process as well as the long-tube soft-flow process, we found that, as modal fibres swell to a higher extent, the fabric movement in rope form as well as package form was difficult, The crease marks were predominant and uneven shrinkage was to the extent of 8 to 11 %. Therefore, in the present study, process was optimised on a jigger in open-width form. Dimensional stability of modal fabrics in terms of residual shrinkage was 3.1 % and 2.8%, warp as weft-wise, respectively. Source

Barrier fabrics are required to be resistant to penetration by liquids and, with the appropriate fabric construction and finishing, can be made resistant to penetration by microbes. The barrier fabrics developed in this study were constructed with a compact structure. The fabrics were finished to impart antibacterial property. The developed fabrics were tested for antibacterial properties, water-vapour permeability, water repellency and air permeability. These fabrics have barrier properties as well as the necessary comfort level for barrier fabrics (bed sheets, mattresses, etc). Source
