Provided herein is a method for decolorizing textile materials under hydrothermal conditions using dye adsorbent materials. The process is non-toxic and environmentally friendly, and the adsorbent materials can be repeatedly used. The textile materials are textile materials dyeable with disperse dyes. Further provided is a system for decolorizing textile materials. The decolorization system is designed to allow the adsorbent materials to react with the textile materials in a contact manner and a non-contact manner.

A method of forming an active agent infused linear material includes passing a substantially linear polymeric substrate through a linear substrate infusion chamber in a first direction, flowing a liquid infusion solution through the linear substrate infusion chamber in a second direction, and contacting the linear substrate with the liquid infusion solution at an infusion temperature and for an infusion time effective to infuse the one or more active molecules into or onto a surface of the linear substrate, thereby forming an active agent infused linear material. The liquid infusion solution includes one or more active molecules. The second direction is substantially opposite or substantially parallel to the first direction. A linear substrate infusion system and a polymeric linear substrate are also disclosed.

A method for dyeing artificial fibers comprises preparing an artificial fiber, and adding a dyestuff, a crosslinking agent, and an appropriate amount of water into a tank for mixture. Then, the artificial fiber is immersed in the tank to obtain a dyed artificial fiber, and the dyed artificial fiber is pressed by a roller set. Finally, the dyed artificial fiber is dried out.

The invention discloses a wool raw wool washing device for chemical fiber production, which includes a washing machine. The washing machine is provided with a working cavity. A front end wall of the working cavity is provided with a storage cavity with an upward opening. The wool raw wool is installed in the washing machine. Two dispersing mechanisms are symmetrically arranged in the working cavity in the storage cavity, and the dispersing mechanism includes a connecting shaft rotatably connected to the rear wall of the working cavity. A rotating wheel is fixed at the front end of the connecting shaft. The connecting shaft is provided with a collar that can slide back and forth, and the rotating wheel is provided with a slidable dispersing rod. The rotation of the connecting shaft can drive the rotating wheel to rotate, and the device can disperse the raw wool in the lump. After washing into small balls, it has a high washing efficiency, and by dispersing into small balls, it helps to discharge the stones and branches in the wool, and has a good washing effect. The overall mechanical linkage of the device is relatively good, High, more energy efficient.
