Apparatus for qualification and repair of multi-filament tow are provided herein. In some embodiments, an apparatus in for inspecting and repairing a multi-filament tow includes a first spool having a multi-filament tow wound on the first spool; a first tow tensioner following the first spool to impart a predetermined tension on the multi-filament tow; a de-sizing chamber comprising a heater to heat the multi-filament tow to a first temperature suitable for removing a coating on the multi-filament tow; an inspection chamber configured to inspect the multi-filament tow for defects; a repair chamber configured to repair the defects in the multi-filament tow; a second tow tensioner following the repair chamber to impart a predetermined tension on the multi-filament tow; and a second spool following the second tow tensioner to collect the multi-filament tow.

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 conveyor-driven fabric dyeing machine includes a recovery container and a dye chemical saving structure. One or multiple containers are provided for recovering and storing hot water for use in a next dyeing operation in order to achieve an effect of saving energy and shortening dyeing time. If desired, liquids for dyeing may be directly collected and recovered, such as water with low contamination or alkali liquid for specific treatment, for use in a next dyeing operation in order to achieve an effect of saving water and reducing the amount of chemicals consumed, and also to reduce the amount of dye and chemicals that is consumed due to oxidation and reduction caused by air. The recovery container may be provided therein with a heat exchanger for recovery of heat. A gas filling opening is formed in the machine body for introducing a gas to expel out air.

A dyeing machine with symmetrical double spiral fabric tanks includes a barrel body with a fabric inlet, two spiral fabric tanks arranged side by side with each other in the barrel body and installed on both sides of the fabric inlet respectively, and each spiral fabric tank having a fabric guiding tube, a spiral fabric sliding plate and a receiving tank. The two fabric guiding tubes are disposed proximate to adjacent sides and facing to the front side and arranged symmetrically with respect to the left and right sides. The two spiral fabric sliding plates are coupled to the rear end of the two fabric guiding tubes and configured to be spirally from top to bottom, so that cloths can be dipped and dyed in the two spiral fabric tanks.
