Description

Technical Field

[0001] This application relates to the field of textile printing and dyeing finishing technology, and more specifically, to equipment and operating method for impregnating and finishing high wear-resistant, stain-resistant, and water-repellent seat fabrics. Background Technology

[0002] As people's demands for quality of life increase, seat fabrics (especially car seat and sofa fabrics) not only require a comfortable feel and beautiful color, but also emphasize functionality, such as water repellency, stain resistance and abrasion resistance. At present, the industry's common practice is to use a padding process to treat the fabric with functional additives. A search revealed an existing patent (publication number: CN112760863B) that discloses a fabric padding and dyeing device, comprising a tank, a guide wheel rotatably disposed within the tank, and a heating wire disposed at the bottom of the tank. The guide wheel is rotatably connected to the side wall of the tank for guiding the fabric to be processed. A oscillating padding box is disposed in the middle of the tank, capable of swinging up and down to agitate the impregnation liquid and padding the fabric through the reaction of the impregnation liquid. This allows for multiple impregnations of the fabric simultaneously in the impregnation liquid while only lightly agitating it. In the process of developing this application, the inventors discovered the following problems with the prior art: Existing padding and finishing equipment and processes are prone to floating or failing to fully penetrate high-density seat fabrics, resulting in auxiliaries only adhering to the surface and the internal fibers not being treated, affecting washability and durable abrasion resistance. Furthermore, auxiliaries in traditional impregnation tanks tend to settle or form skins after prolonged periods of stillness, and excess auxiliaries cannot be effectively recycled, causing waste and environmental pollution. Therefore, in response to the aforementioned technical issues, a high-wear-resistant, stain-resistant, and water-repellent seat fabric impregnation and finishing equipment and operating method are proposed.

10. An operating method for a high abrasion-resistant, stain-resistant, and water-repellent seat fabric impregnation and finishing equipment, employing the high abrasion-resistant, stain-resistant, and water-repellent seat fabric impregnation and finishing equipment as described in any one of claims 1-9, characterized in that: The operation method includes the following steps: Step 1: Mix the fluorinated water repellent, nano antifouling particles, and wear-resistant resin in a specific ratio, dilute with water and stir evenly, then add to the recycling filter box (34), the pre-impregnation box (3), and the secondary impregnation box (41); Step 2: Place the fabric onto the unwinding roller (11) and use the pre-tensioning swing frame (2) to eliminate the internal stress of the fabric, so that the fabric can be smoothly introduced into the pre-impregnation box (3) under the guidance of the ceramic guide roller (311). Step 3: The fabric enters the pre-impregnation tank (3) for initial impregnation, and when it leaves the pre-impregnation tank (3), the air bubbles inside the fabric are discharged under the action of the ultrasonic vibration roller (33), which promotes the penetration of the additives, and enters the secondary impregnation tank (41) for secondary impregnation under the guidance of the ceramic guide roller (311). Step 4: Complete the secondary impregnation. The fabric is subjected to the action of the upper roller (42) and the lower roller (43) to remove excess surface additives; Step 5: After the impregnation process is completed, the fabric is put into the vacuum water absorption box (5) to perform micro-water absorption treatment on the reverse side of the fabric to prevent the migration of the additives. Then it is put into the drying and shaping box (6) for drying and shaping, and then rolled onto the take-up roller (71).
