Technical Field

[0001] The present application relates to the technical field of polyester grey fabric processing, and in particular to a polyester grey fabric surface dust removal device. Background Art

[0002] Polyester greige fabric is a raw, undyed, unfinished fabric woven from polyester fibers. Polyester fibers are strong and can withstand significant tension and abrasion. The resulting polyester greige fabric exhibits excellent wear resistance, wrinkle resistance, and dimensional stability, making it suitable for a variety of durable textiles, such as workwear, outdoor gear, home textiles, and industrial fabrics. During the production process, polyester greige fabric undergoes spinning and weaving to create a uniform, smooth surface. To ensure a clean surface and enhance the quality of the final product, a dust removal device is required to remove dust from the surface of the polyester greige fabric.

[0003] In the related art, the grey cloth in the production and processing of polyester grey cloth is mainly dust-removed by a dust removal device. During operation, the polyester grey cloth is guided and transported into the interior of the device through a cloth guiding device, and then the dust on the grey cloth can be sucked out by a dust suction component provided on the device.
