Basket and process for dyeing textile materials

Abstract

Dyeing basket comprising a substantially cylindrical storage body ( 1 ) having a preset height, with an upper base (U) and a lower base (L), within which the material ( 2 ) to be dyed is disposed, the body ( 1 ) being perforated, characterized in that, close to the upper base of body ( 1 ), at a preset distance (da) from the longitudinal axis (x-x) of the latter, provision is made for two opposite journals ( 30 ) intended for supporting a reel or drum ( 4 ), rotating freely about the common axis (y-y) of said journals, the said journals ( 30 ) being at a preset distance (ds) from the upper base (U) of body ( 1 ), so that the whole surface of drum ( 4 ) will result below the same base (S).

1 ) dyeing basket comprising a substantially cylindrical storage body ( 1 ) having a preset height, with an upper base (U) and a lower base (1), within which the material ( 2 ) to be dyed is disposed, the body ( 1 ) being perforated, characterized in that, close to the upper base of body ( 1 ), at a preset distance (da) from the longitudinal axis (x-x) of the latter, provision is made for two opposite journals ( 30 ) intended for supporting a reel or drum ( 4 ), rotating freely about the common axis (y-y) of said journals, the said journals ( 30 ) being at a preset distance (ds) from the upper base (U) of body ( 1 ), so that the whole surface of drum ( 4 ) will result below the same base (U).  
     
     
         2 ) Basket according to  claim 1 , characterized in that it comprises a sheet ( 5 ), fastened to the inner side surface of body ( 1 ), which sheet allows keeping suitably spaced apart the edges of the material ( 2 ) closer to the drum ( 4 ).  
     
     
         3 ) Basket according to  claim 1 , characterized in that the material ( 2 ) to be dyed is ring-like closed by a temporary sewing, performed by an operator, over the cylinder ( 4 ).  
     
     
         4 ) Basket according to  claim 1 , characterized in that said drum ( 4 ) has a plurality of surface reliefs, both in correspondence of the central body and in correspondence of the right and left frusto conical bases ( 40 ), to allow the movement thereof about said axis (y-y) as a consequence of the jet of-liquid dye delivered from a nozzle ( 6 ) located thereabove.  
     
     
         5 ) Basket according to claims  1  and  4  characterized in that the said nozzle ( 6 ) is a triple nozzle.  
     
     
         6 ) Basket according to  claim 1 , characterized in that it can be positioned inside a tank ( 7 ) provided with a lid ( 70 ) connected with the upper base of the tank, by a hinge ( 71 ) having horizontal axis, and engaged with an actuator ( 72 ) which drives it into rotation about the axis of said hinge, in the opening direction to allow the introduction of the basket within the tank, and in the closing direction to start the dyeing process inside the tank, said actuator ( 72 ) being connected with the lid ( 70 ) by means of a fork structure comprising two parallel arms ( 73 ) which, at one end, are hinged on the body of tank ( 7 ) by a hinge ( 79 ) and, at the opposite end, are joined with each other by a crosspiece ( 74 ), at a point below the crosspiece ( 74 ) the said arms ( 73 ) being connected with the lid ( 70 ) by a lever ( 75 ) which, on one side, is connected with the arms ( 73 ) by a hinge having horizontal axis ( 76 ) and, on the other, is connected with an appendix ( 77 ) of lid ( 70 ) by a further hinge link ( 78 ), the axes of said hinges ( 71 ,  79 ,  76 ,  78 ) being all parallel to each other.  
     
     
         7 ) Basket according to  claim 1 , characterized in that it comprises a funnel element ( 80 ) located below said drum or reel ( 4 ) and into which a jet of colouring liquid is fed through a corresponding conduit ( 8 ).  
     
     
         8 ) Basket according to  claim 1 , characterized in that it comprises a funnel element ( 80 ) located below said drum or reel ( 4 ) and into which a jet of compressed air is delivered.  
     
     
         9 ) Basket according to  claim 1 , characterized in that it comprises means for driving the reel or drum ( 4 ) into rotation about its axis longitudinal (y-y) and about the longitudinal axis (x-x) of basket ( 1 ) at the same time.  
     
     
         10 ) Basket according to  claim 1 , characterized in that it comprises a grip appendix ( 11 ) to allows for the engagement and movement thereof by automatic drive means.  
     
     
         11 ) Operating process for carrying out the dyeing of textile materials, characterized in that it includes loading the materials to be treated into perforated baskets, that is, baskets which are permeable to the bath, prior to dispose the baskets inside the tank containing the bath, the baskets with the material to be treated being stationed at known and preset points of a parking structure and each of them being removed therefrom to be introduced within a dyeing tank, upon completion of the dyeing, each basket being withdrawn from the tank where it was introduced, to be positioned in correspondence of the starting point or other point of the plant where the discharge, that is, the removal of the textile material from each basket, will take place.  
     
     
         12 ) Process according to  claim 10  characterized in that, while the various tanks of the system operate the treatment of the material held in the baskets previously introduced therein, the various baskets located in the parking area can be loaded with other material to be treated or, if they contain material already treated, can be unloaded, that is, emptied out of their relevant content.  
     
     
         13 ) Process according to one or more preceding claims, characterized in that the material held in the baskets is ring-like closed over an element ( 5 ) able to suitably space apart opposite edges of materials under treatment and passing through an element ( 50 ) for the guiding and centering thereof with respect to a drum or reel ( 4 ) idly supported inside the baskets.
