20230090987 · 2023-03-23 ·

A method for decolorizing a polyester fabric is provided, which includes: providing a dyed polyester fabric, in which a material of the dyed polyester fabric contains a dye and a water repellent; providing a composite solvent, in which the composite solvent includes propylene glycol methyl ether (PM) and acetic acid that are mixed together; and performing an extraction process, which includes using the composite solvent to wet the dyed polyester fabric and remove the dye and the water repellent from the material of the polyester fabric by extraction, so as to obtain a reduced polyester fabric.

System and method for treating textile material with ozone

A system and a method for treating a textile material with ozone gas. The system includes: an ozone gas supply system, a hollow chamber fillable with ozone provided by said gas supply system, a textile-feeding port connected to said chamber and comprising a first liquid fillable tank, a textile-discharging port connected to said chamber and comprising a second liquid fillable tank, guide rollers, driving rollers, at least one tension compensator located inside the hollow chamber. The system is adapted for implementing the method, the latter including: using the system and providing liquid to said first and second tanks, providing ozone gas to said hollow chamber, driving the textile material to pass tensed through the system while controlling its tension using the tension compensators. The use of the tension compensators prevents the formation of ozone induced defects on the textile material.

ELECTROCHEMICAL REACTOR AND ITS CLEANING OR REGENERATION

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.

Dyeing and Finishing Method for Linen Cotton Textile Fabric with High-shrinkage

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.

Rinsing station for spray dyeing system

A rinsing station for removing residual materials from a fabric being dyed or bleached. The rinsing station includes a first pair of rinse spray nozzles. One of the first pair directed to spray a rinse fluid downwardly onto incoming dyed fabric. The other of the first pair directed to spray the rinse fluid upwardly onto the incoming dyed fabric. The rinsing station also includes a pair of nip rollers downstream for the first pair of rinse spray nozzles for extracting the rinse fluid.
