A system for the functionalization of polyolefin fiber includes a reactor chamber, a fiber pulley system, and a precursor sprinkler system. The reactor chamber defines an interior reactor space and a plurality of fiber inlet/outlet pairs positioned at opposite ends of respective fiber processing axes. The fiber pulley system is arranged to direct polyolefin fiber through the plurality of fiber inlet/outlet pairs, along a fiber processing path comprising the respective fiber processing axes. The precursor sprinkler system is operable to aerosolize a precursor solution and contact the aerosolized precursor solution with the polyolefin fiber. A method for functionalizing polyolefin fiber includes aerosolizing the precursor solution to form an aerosolized precursor solution, passing polyolefin fiber along the fiber pulley system into the reactor chamber, contacting the polyolefin fiber with the aerosolized precursor solution, and passing functionalized polyolefin fiber out of the interior reactor space of the reactor chamber.

An apparatus for dye application to textile manufactures, exhaustion of the applied dye, and drying of the textile manufacture. The apparatus, in some implementations, includes a dye applicator that applies dye evenly to a textile manufacture of varying length, one or more steam release conduits for heating the textile manufacture with applied dye to exhaust the dye, and a blower system to dry the textile manufacture after application of the applied dye.

A blower for an airflow dyeing machine is provided. Each four nozzles of the airflow dyeing machine shares a blower, the blower being disposed at a central position of the four nozzles; wherein the blower comprises: a motor, a blowing machine, a primary air duct, a secondary air duct, an air inlet and an air outlet, the motor driving the blowing machine to rotate, the blowing machine comprising a blowing machine housing and impellers, the impellers being disposed inside the blowing machine housing, two air outlets of the blowing machine being oppositely arranged and are disposed on two sides of the blowing machine housing which respectively supply air to the two nozzles at the two sides, the air inlet of the blowing machine being on a side opposing the motor, the two air outlets of the blowing machine being respectively coupled to one ends of the two primary air ducts.

A phase-transfer catalytic color fixation processing method for textile includes the following steps: (1) dry-dyeing a textile with disperse reactive dyes in supercritical carbon dioxide fluid under waterless condition; (2) putting the textile in a phase-transfer catalytic fixation device, taking phase-transfer catalyst as the carrier of circulated supercritical carbon dioxide fluid, transporting the ionized fixing catalytic alkaline substance from aqueous phase to hydrophobic supercritical carbon dioxide fluid phase, getting full contact with functional groups on fibers, resulting in the fixing catalytic reaction with disperse reactive dyes.

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.
