After dyeing, the fabric is rinsed with clean water. Finally, the fabric needs to be dried using a drying machine. Some fabric drying machines use hot air drying, and the drying temperature can reach 200℃. This process produces a large amount of hot air containing high-temperature steam. The traditional way to handle this hot air containing high-temperature steam is to directly discharge it into the atmosphere. During the cleaning of the sizing agent, the fabric is first rinsed in a pool of 80℃ soap solution and then rinsed with 30℃ clean water.
