  • Continuous pressure decatising of fabrics and setting of staple fibre assemblies
    Patent number: 6381883
    Abstract: A method and apparatus for continuously pressure decatising a fabric include a rotatable drum (12) around which an endless belt (15) is arranged to travel for conveying a fabric (19) (and optionally a moisture laden textile (20)) between the facing surfaces of the belt (15) and the drum (12). The drum (12) is heated and fabric (19) is pressed between the belt and the drum as it is conveyed through the apparatus. The fabric (19) is subjected to pressurized saturated steam, which may be generated by evaporation of the moisture in textile (20) when it contacts the heated drum, as it is pressed. Various options other than use of a moisture laden textile (20) for supplying the steam are disclosed. The invention involves enclosing the drum in a pressure vessel (14) within which a compressed air atmosphere at ambient temperature is maintained.
