Abstract
A process is provided for mechanically surface-finishing a textile fabric which comprises continuously feeding said fabric from a source of supply, such that said fabric lies in a single plane, subjecting successive adjacent sections of the fabric to intermittent mechanical impact with an abrasive means across the width of said fabric thereby avoiding substantial sustained contact between the fabric and the abrasive means, the mechanical impact being at a force and frequency sufficient to cause a substantially uniform modification of the surface characteristics of the fabric. Textile fabrics with modified surface which may be made by the above process are also provided. Apparatus for mechanically surface-finishing a textile fabric according to the aforedescribed process is further provided.
Claims5
An apparatus for mechanically achieving a substantially uniform modification of the hand characteristics of a textile fabric having fibrous components which comprises means for continuously feeding said fabric from a source of supply such that said fabric lies in a single plane, at least one rotating abrasive roll;
- at least one intermittent impact means for subjecting successive adjacent sections of said fabric to intermittent mechanical impact with said abrasive roll across the width of said fabric, thereby avoiding substantial sustained contact between said fabric and said abrasive roll;
- said intermittent mechanical impact means being disposed across the fabric width, parallel to the abrasive roll near the reverse side of the fabric from said abrasive roll, thereby causing the portions of the fibrous components exposed to said intermittent mechanical impact with said abrasive roll to be substantially scarred and to be provided with a multiplicity of generally short, rather thick, lamella shaped protrusions extending therefrom.
