Embodiment Construction
[0013] The present invention will be further described in detail below in conjunction with specific embodiments and accompanying drawings.
[0014] Such as figure 1 As shown, a dyeing and finishing pretreatment process that can reuse wastewater, the process steps are as follows: firstly, the fabric is sent to the open-width scouring machine 2 for scouring, and the pretreatment liquid during scouring uses bugong tea saponin As a pre-treatment aid; the fabric is boiled and rolled out of excess moisture and then enters the padding machine 3 for padding treatment; the fabric is steamed in the steam box 4 after the padding process is completed and the excess moisture is rolled out. In the example, the top of the steam box 4 is provided with an insulating layer that can prevent condensation water from being produced, so as to prevent the top of the steam box 4 from generating condensation water and dripping on the fabric when the steam box 4 is working, because if any condensation w...
