Abstract
A suede-like micro-fibril finish is imparted to fibrillatable cellulosic materials by open width hydraulic treatment. Additional enhancement of the fabric finish is obtained by post hydraulic enzyme and wet processing treatments. Fluid treated fabrics of the invention are characterized by substantially uniform fibrillation of fibers within the fabric body and surface areas.
Claims35
A method for finishing textile fabric including fibrillatable cellulosic fibers, the method comprising the steps of:
- supporting the fabric on an open width support member, and
- uniformly and continuously impacting at least one side of the fabric with a continuous curtain of fluid with a sufficient energy to fibrillate fibers in the fabric.
A method for finishing textile fabric including fibrillatable cellulosic fibers, the method comprising the steps of:
- supporting the fabric on an open width non-porous support member, and
- uniformly and continuously impacting at least one side of the fabric with a continuous curtain of fluid with a sufficient energy to fibrillate fibers in the fabric.
