摘要:
A continuous dyeing device and related processes using indigo and/or other colorants for warp yarn chains and/or for fabrics, equipped with at least a first and a second dyeing compartments containing dyeing baths, the first and second dyeing compartments being enclosed, at least partially, in a hermetically sealed chamber. The device also includes at least one squeezing element interposed between the two dyeing compartments and a plurality of cylinders for heating and/or dehydrating the yarn and or the fabric, thereby increasing the diffusion and the absorption of the colorant. The cylinders are positioned downstream of the first dyeing compartment and squeezing element.

Textile yarn package supporting carriers are disclosed for use in textile dyeing machines to enable the machine to be effectively operated at less than full capacity. Each carrier has a base with multiple upstanding package supporting posts each having a longitudinal package supporting portion extending upwardly from the base and dimensioned to securely support a predetermined maximum number of packages on each post. A cap mounts to the spindle portion of each post for movement therealong into engagement with the outermost package on the post. The cap has a latching arrangement with a latch plate disposed to be selectively movable between a disengaged or release position wherein the latch plate does not impede relatively free sliding movement of the cap along the post and a second engaged position wherein the latch plate is braced against the post to prevent sliding movement of the cap along the post.
摘要:
A horizontal package dyeing machine in which yarn packages are supported in carriers that have a base with tubular posts projecting therefrom for stacking yarn packages thereon and a wall secured to and extending upwardly from the periphery of the base to form an enclosure for confining treating liquid. The base is formed with two liquid distribution chambers, one being an upper chamber communicating with the interior of the posts and the other being a lower chamber communicating with the interior of the enclosure. The distribution chambers have open ends that can communicate with liquid supplying and withdrawing ducts of the machine for circulation of treating liquid within the carrier enclosure. The carriers are dimensioned for positioning two carriers in a vessel with the open ends of the distribution chambers in communication for flow of treating liquid therebetween. The open end of the discharge chambers of a carrier at the opening end of the vessel has its discharge chamber ends blocked by a positioning member on the lid of the vessel. An insert member may be used in place of a second carrier when dyeing a half batch of yarn packages or less, with the insert member having a flow blocking surface disposed against the distribution chamber openings at the adjacent end of the adjacent carrier and having its other end against the positioning member of the lid of the vessel.

In a method of dyeing yarn cheeses stacked on a spindle and pressed to a definite compression degree by flowing a dye liquor through the yarn layers, the dye liquor is flowed while undergoing pulsation in a minimized flow rate and a minimized flow pressure, thereby enabling even permeation of the dye liquor into yarn layers and accordingly, even dyeing.
摘要:
A low-liquor-ratio dyeing apparatus comprising a perforated cylindrical beam rotatably supported within a horizontal vessel for supporting on its periphery materials to be dyed, a liquid flow circulation system for forcing dying liquid through the materials radially outwardly of the beam, a sprinkler chamber mounted on the ceiling of the vessel for spraying the liquid over the upper portion of the beam, the ceiling of the vessel, and inner side walls of the vessel, and a liquid supply bypass pipe branched from the supply side of the circulation system and connected to the sprinkler chamber.

The present invention consist of a method and apparatus for treating texturized yarn to improve its quality whereby a yarn is produced with greater bulk and more uniformity and dyeing which eliminates streaking and produces yarn spools which are more easily handled by the workmen, and which produce fabrics of greater density, flexibility, and greater stretch and rebound qualities.
摘要:
Apparatus for dyeing a body of textile material including a tank lying below floor level for containing a supply of dye solution and having a vertical perforated hollow spindle extending through the body of textile material and extending away from the tank above the floor level. A pump is connected to the tank and to the spindle to circulate the dye solution from the tank to the spindle for passage from the spindle through the body of textile material and then back to the tank. A compressor is connected to the spindle to cause air to pass through the body of textile material, and means is provided to heat the air to assist in the drying of the material.
摘要:
A dyeing apparatus comprises a dyeing vessel adapted to contain a dyeing liquid therein, a rotary shaft rotatably disposed as laterally suspended in the dyeing vessel, an impeller adapted to flow the dyeing liquid in a direction parallel to the rotary shaft, and a reel for permitting an article for dyeing to be rolled up thereon, the impeller and the reel being attached to the rotary shaft. The dyeing of the article rolled up on the reel is effected by causing the dyeing liquid to pass by permeation through the article from the lateral terminal part thereof by the rotation of the impeller. The rotary shaft may be rotated reversibly during the course of the dyeing.
摘要:
Textile yarn package supporting carriers are disclosed for use in both horizontal and vertical textile dyeing machines to enable the machine to be effectively operated at less than full capacity, Each carrier has a base with multiple upstanding package supporting posts each having a longitudinal package supporting portion adjacent the base and a longitudinal threaded spindle portion extending outwardly in alignment therewith, The package supporting portion is dimensioned to securely support a predetermined minimum number of packages on each post and adapters are provided for slidable mounting onto the spindle portions of each post to accommodate additional yarn packages up to the maximum capacity of the carrier. A threaded cap mounts to the spindle portion of each post for movement therealong into engagement with the outermost package on the post.
