Abstract:
The present disclosure is directed to a process and apparatus for the heat-treatment of textile materials, particularly those materials which are only slightly or not permeable to air when in a wet condition. More particularly, the present disclosure is directed to a process and apparatus for producing a steam cushion at the surface of the material being treated, said material being conveyed on the surface of sieve drum means.
Abstract:
The damage to the selvage of a textile fabric and distortion of this fabric when subjected to a thermosetting or thermosoling process is avoided by passing hot air or other inert gas onto and through the fabric while it is supported on a perforated drum which is covered with a fine meshed sieve fabric.
