Non-woven cellulosic fiber fabric with increased water retention and low basis weight

摘要

A nonwoven cellulosic fiber fabric 102 made directly from the lyocell spinning solution 104 is described. Fabric 102 comprises a network of substantially endless fibers 108. The fabric 102 exhibits a water holding capacity of 850% by mass or more. In addition, the fabric 102 comprises a mass per unit area of less than 25 grams per square meter. Further described are methods and apparatus for making such fabrics 102, products or composites comprising such fabrics, and various uses for such fabrics 102.
