Description

Technical Field

[0001] The invention relates to the field of textile coating processing, and in particular to an air-spinning process coating processing device and a coating method. Background Art

[0002] Air-jet spinning is a spinning technology that uses air flow to condense and twist fibers in a high-speed rotating spinning cup to output them into yarn. Air-jet spun yarn is generally coarse and suitable for making denim fabrics, etc. Textile coating is a layer or layers of film formed on the surface of the fabric through bonding, which can not only improve the appearance and style of the fabric, but also increase the function of the fabric, making the fabric have special functions such as waterproof, water pressure resistance, breathable and moisture permeable, flame retardant and anti-fouling, as well as light-shielding and reflective.

[0003] Since air-spun fabrics are usually thicker and stronger, the coated fabrics are usually collected by winding them around a reel during the coating process. Since the air-spun fabrics themselves have a certain elasticity, when the reel length is greater than the fabric width and there are no limits at both ends, the air-spun fabrics are easily offset during the winding process, resulting in the fabric being unable to form a complete roll, which can easily lead to messy winding and inconvenience in collecting the coated fabrics.
