Abstract
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.
