Centrifugal dyeing apparatus for treating wound fabrics

Abstract

An apparatus to treat wound sheet forms, especially textile sheets, with fluids is provided. The treatment includes the bleaching, the dyeing, and the washing of knitted and woven textile and fleece. Such sheet forms may include any of cellulosic, animal, and synthetic fabric and their compositions. The sheet forms wound onto a perforated dyeing beam are treated with the fluids by means of centrifugal force in such a way that a regular treatment with the least use of water, chemicals, and energy is possible. A centrifugal dyeing apparatus includes a closable container, a pump to circulate a treating fluid, a driven dyeing beam, which is rotatably supported in the container, arranged to hold a lap made of a textile sheet form and having a tube with a perforation, wherein support sustainers are provided, wherein the support sustainers radially support the lap, and wherein the support sustainers (6) are attached to the dyeing beam.

1 . A centrifugal dyeing apparatus comprising
 a closable container;   a pump to circulate a treating fluid; and   a driven dyeing beam rotatably supported in said container and arranged to hold a lap made of a textile sheet form and comprising a tube with a perforation;   wherein support sustainers are provide;   wherein said support sustainers radially support said lap; and   wherein said support sustainers are attached to said dyeing beam.   
     
     
         2 . A centrifugal dyeing apparatus according to  claim 1 , wherein said support sustainers are arranged to be coaxial to said dyeing beam. 
     
     
         3 . A centrifugal dyeing apparatus according to  claim 1 , wherein said support sustainers are formed as closed hollow profiles. 
     
     
         4 . A centrifugal dyeing apparatus according to  claim 1 , wherein said support sustainers are adjustable so as to fit to the thickness of said lap. 
     
     
         5 . A centrifugal dyeing apparatus according to  claim 1 , wherein said support sustainers are arranged alongside the entire width of said lap. 
     
     
         6 . A centrifugal dyeing apparatus according to  claim 1 , wherein perforated support sheets are attached to said support sustainers and wherein said perforated support sheets fit said lap. 
     
     
         7 . A centrifugal dyeing apparatus according to  claim 6 , wherein said perforated support sheets cover at least 10% of the circumference of said lap and the entire width of said lap. 
     
     
         8 . A centrifugal dyeing apparatus according to  claim 6 , wherein each said support sustainers forms a unit together with said perforated support sheets. 
     
     
         9 . A centrifugal dyeing apparatus according to  claim 1 , wherein said support sustainers are attached to said dyeing beam at an unperforated region of said tube by support sustainer fixtures. 
     
     
         10 . A centrifugal dyeing apparatus according to  claim 1 , wherein said support sustainers are attached to said dyeing beam at an unperforated region of said tube by screws. 
     
     
         11 . A centrifugal dyeing apparatus according to  claim 1 , wherein said dyeing beam comprises side plates attached to said tube. 
     
     
         12 . A centrifugal dyeing apparatus according to  claim 11 , wherein said support sustainers are attached to said side plates of said dyeing beam by support sustainer fixtures that are attached turnably around close-tolerance screws to said side plates, and the position of said support sustainer fixtures can be locked by spring bolts, or wherein said support sustainers are attached to said side plates of said dyeing beam by screws and screw nuts. 
     
     
         13 . A centrifugal dyeing apparatus according to wherein at least one strap is applied around said support sustainer and said lap and wherein said at least one strap is adjustable in its length. 
     
     
         14 . A centrifugal dyeing apparatus according to  claim 1 , wherein said container is constructed as a pressure vessel and wherein said dyeing beam is removable from said container and wherein a spraying tube arranged concentrically to the dyeing beam is provided. 
     
     
         15 . A centrifugal dyeing apparatus according to  claim 1 , wherein watery solutions including at least one of a solvent and CO 2  in a supercritical state is used as said treating fluid.
