The present invention relates to a dynamic scheduling system and method of a dyeing process using a genetic algorithm, and more particularly, to technology which performs an optimized process corresponding to an ordered work command in a dyeing process by using process scheduling based on a genetic algorithm to increase production efficiency.

The embodiments herein discloses a system for dyeing fabrics on-demand, comprising a flatbed mechanism for loading a substrate for dyeing; an ink feeder mechanism, consisting of at least Cyan, Magenta, Yellow and Black (C, M, Y, K) colors and a color combiner mechanism or color mixer to combine the inks and create a composite ink; at least two nozzle heads to deposit the composite ink on both sides of a substrate; an operator console; and a reset mechanism. The nozzle is configured to move across the entire width of a substrate from one side to the other, while the substrate rolls to aid dyeing. The nozzle dyes a single color at any given time.

Provided herein is a method of separating spandex from textile blends using biosolvents. The recovered material is of high purity while the chemical structure and molecular weight remain substantially unaffected by the treatment.

An electrochemical reactor suitable for reducing dye to leucodye, comprises at least four electrolytic cells, wherein the electrolytic cells are provided in the form of at least two stacks of at least two electrolytic cells each such that one stack at a time can be separated for cathode or anode regeneration during suspension preparation.

Another aspect of the invention relates to methods for reducing total water content necessary in industrial treatment of garments. Another aspect of the present invention relates to processes and methods of forming a foam that can be used for textile treatment.

A dyeing and finishing method for linen cotton textile fabric with high-shrinkage is described in the present invention, comprises the steps as below: preprocessing, pickling, dyeing and shaping, which can make the fabric with sufficient shrinkage and provide a qualitative sense of linen cotton. Through the above way, in the dyeing and finishing method for linen cotton textile fabric with high-shrinkage provided by the present invention, washing treatment on the fabric by the preprocessing and the pickling before dyeing makes the colorizing more easy and decreases the color difference and colored spot after dyeing, opening the fiber of the fabric and cooling shrinkage during the dyeing process can obtain the unique product style, with a handle more like the linen cotton effect, and a pellet feeling appeared on the cloth cover and the product fabric more like the woven fabric.

Systems and methods are described whereby a deoxygenated liquid dye material is made by supplying the deoxygenated inert gas to a liquid dye material that is susceptible to oxidation, and mixing the liquid dye material in the presence of the supplied deoxygenated inert gas with water and at least one dye formulation component selected from the group consisting of reducing agents, pH adjusters, foaming agents, wetting agents and auxiliary chemicals to form a deoxygenated aqueous dye composition having an oxygen content of 30 ppm oxygen or less. A supply of inert gas may be provided which is then passed to a gas purifier to reduce oxygen content in the inert gas to, e.g., 1 ppb oxygen or less. The deoxygenated aqueous dye composition that is formed may have an oxygen content of 1 ppm or less.

Particular techniques involve a device for wetting multiple threads with a fluid, and a dosing pump which is connected to the wetting means by multiple conveying lines. The dosing pump has multiple conveying means for generating multiple dosing flows of the fluid and has multiple pump outlets, to which the delivery lines are connected. The conveying means are formed by at least one planetary gear set arranged between housing plates. To achieve, as far as possible, a uniform throughflow without a significant dead space volume, multiple planet gears of the planetary gear set are guided freely by a centering plate between adjacent housing plates. The planet gears of the planetary gear set have in each case one passage opening, which are connected by a channel system to a central pump inlet. It is thus possible to realize close fits and flushing of gaps.

A waterless dyeing device for cone yarn, a waterless dyeing method and a produce are provided; wherein the device comprising: a dye autoclave (1); a dyeing autoclave (2); a recycle autoclave (6); a dyeing circulation system in which the dye autoclave (1), the dyeing autoclave (2) and the recycle autoclave (6) are in fluid communication with; wherein further comprises: a cone yarn inlet formed on the top of the dyeing autoclave (2), which is provided with a sealing cap (7); a cone yarn center shaft (10) vertically disposed at the center inside the dyeing autoclave, which is a perforated outlet tube with fluid discharge holes opened on the side wall; an intake pipe (13) disposed on the bottom of the dying autoclave (2) which is in communication with the cone yarn center shaft (10); a dyeing autoclave outlet (9) disposed on the dying autoclave (2); and a CO2 container (4), a pressure pump, a circulation pump (3) and conduits which are included in the dyeing circulation system. The dyes are disposed in the dye autoclave (1) and the cone yarns are disposed inside the dyeing autoclave (2), CO2 is introduced into the dye autoclave (1) to dissolve the dyes gradually, and the CO2 carrying the dyes to the dyeing autoclave (2) to dye and diffuse. The present invention has the advantages of being high in production efficiency, even in dyeing effect and high in safety, and is suitable for waterless dyeing of polyester cone yarns.

Apparatus for the controlled withdrawal and dispensing of liquids, comprising a structure (S) with a platform (1) housing a first series of containers (2) containing liquid substances and a second series of containers (3) adapted to receive the substances of the containers of the first series, the apparatus further comprising means for withdrawing the liquids from the containers of the first series and dispensing such liquids into the containers of the second series. On each container of the first series is inserted a half-pipette consisting of a barrel (4), a piston (5) devoid of actuation rod, and a needle (6). The withdrawing and dispensing means comprise a unit (9) provided with a vertical rod (95, 96) for actuating the piston of each half-pipette, said unit being constrained to a carriage (10) that can be moved above the platform. The unit (9) is movable vertically from and towards the platform (1).
