[0003] Based on the above, the inventors found that there are the following problems:

[0004] The above-mentioned fabric heat stretching device has a relatively good heating effect and can also reduce wrinkles on the fabric before processing. However, firstly, dust and impurities will be generated during the heat stretching process and attached to the fabric, which will affect the output quality of the fabric. Secondly, since the fabric is in a wet state before entering the equipment, due to the different moisture levels of the fabric, it is easy to maintain a uniform transmission speed during the subsequent drying and heating process, resulting in the drying effect not meeting the requirements.
