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.

An ultra-low liquor ratio fabric dyeing machine includes an assisting heat exchanger and a direct temperature rise/lowering device. The assisting heat exchanger or multiple ones of the assisting heat exchanger are additionally included in the dyeing machine. The assisting heat exchanger includes an external pipe that is mounted to a pump pipe of a pump at an inlet port, an outlet port, or both inlet and outlet ports thereof and is mounted with inlet and outlet openings for steam and cooling water in order to serve as an external casing that houses the pump pipe, while the pump pipe serves as a heat exchange pipe of the heat exchanger. The direct temperature rise/lowering device is mounted to a dyeing bath of the dyeing machine to directly introduce steam or cold water therein for quickly increasing or decreasing the temperature of the dyeing bath.

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.

An energy-saving dyeing machine includes a body, a liquid dyes supply device, a liquid dyes heating device having a direct-heating heat exchanger, and a cooling unit connecting to the direct-heating heat exchanger by a series connection. When heating up the liquid dyes, the liquid dyes enters the direct-heating heat exchanger from the liquid dyes supply device via a supply tube, saving several heating procedures and unnecessary energy wastes. Additionally, an outer wall is surrounding the body to form a surrounding space for the heated exhaust gas from the direct-heating heat exchanger to enter and reheat the liquid dyes in the body again, making a better use of the heat energy.
