Abstract
Anhydrous dyeing method for textile, including the steps of: using a pure dye as a plating material and a textile fabric as a substrate, and depositing the dye onto a surface of the textile fabric by using a physical vapor deposition technique. The color of plated textile fabric is fixed through steaming, heat setting or other post-processing methods. The invention achieves the purpose of dyeing textile fabric by depositing dye onto the surface of the textile fabric uniformly and densely using a physical vapor deposition technology, and fixing the color in a finishing step. The process is simple and convenient, produces no waste water discharge, has a high utilization rate of dye, and is operable and feasible for mass production.
Claims5
An anhydrous dyeing method for textile, comprising the steps of:
- (a) suspending substantially uniformly dried particles of a dye in a closed space with a predetermined degree of vacuum at a predetermined temperature;
- (b) passing a fabric to be dyed through the closed space to allow the dried dye particles adhere directly from a suspension state in the air to the surface of the fabric to achieve a dyeing effect, wherein the enclosed space does not contain supercritical carbon dioxide.
