Method for dyeing a hook-and-loop fastener strap

Abstract

A method for dyeing a hook-and-loop fastener strap is disclosed. The hook-and-loop fastener strap continuously passes through a basic or neutral dyeing solution in a dyeing device. The dyeing solution attaches itself to the hook-and-loop fastener strap. The dyeing solution has a dye that binds to the hook-and-loop fastener strap only when the dyeing solution is in an acidic state. After passing through the dyeing device, the hook-and-loop fastener strap with the deposited dyeing solution is passed through a damper, causing the dyeing solution to become acidic. The dye adheres to the hook-and-loop fastener strap to dye the hook-and-loop fastener strap. A dyeing system for implementing the method is also disclosed.
