Embodiment Construction

[0020] With reference to the accompanying drawings, figure 1 The textile material dyeing machine of embodiment 1 is shown, and its whole is designated by numeral 10 . In particular, the type of dyeing machine known as "vertical" (generally extending vertically and with doors closing above) is designed to dye such materials wound on bobbins or cones. The materials may be, for example, yarns, pre-yarn ribbons, filler threads, and the like. Conical bobbins can be rigid or compressive.

[0021] The dyeing machine comprises a pressurized container 11 intended to be filled to level 12 with a specific liquid constituting the dyeing liquor. In the container there is a material holder or bracket 13 (liftable and removable) for supporting the textile material immersed in the dye liquor. In this embodiment, the bracket comprises a base 14 from which vertically protruding rods 15 (for example arranged in a circle) serve to axially support the textile material wound on a bobbin 16 . A ...

Abstract

A dyeing machine for textile materials such as yarn, sliver, loose fibers and the like which are not fabrics, said dyeing machine comprising a sealed container (11, 111, 211 , 311, 411), there is a material bracket (13, 113, 213, 413) in the container that can be used to support the textile material immersed in the dye liquor, and the dye liquor circulation device (17, 117, 217 , 317, 417) make the dye liquor flow through the textile material in the material bracket, and it is characterized in that: the dyeing machine also includes another external circulation device (19, 119, 219, 319, 321, 419) , this additional external circulation means creates an additional movement of the liquor in the sealed container, in the part of the liquor outside the textile material on the carriage.

Description

technical field [0001] The invention relates to a dyeing machine, which is used for dyeing textile materials before weaving, and the forms of said textile materials include cheeses, skeins, loose fibers, combed tops, filling threads, tows and the like. Background technique [0002] In the prior art, dyeing machines for these materials are known, which comprise a sealed container for filling the dye liquor, in which there is a carriage for supporting the textile material immersed in the dye liquor. Material. The dye liquor is circulated through a circulating pump, causing the dye liquor to flow through the textile material on the carriage. [0003] For example, in the case of textile material wound on bobbins, which are stacked on rods, the hollow center of the bobbins forms a conduit for distributing the dye liquor, which flows radially through the bobbins. [0004] Dyeing or treatment cycles require thermal cycling (raising or lowering the temperature of the dyebath), whi...
