Elastic functional textile fabric and dyeing and finishing method thereof

Abstract

This invention relates to an elastic functional textile fabric and dyeing and finishing method thereof. The fabric provided mainly comprises at least one elastic yarn. An ironing machine is used to process the fabric to maintain warp-wise smoothness and flatness. After ironing, a sanforizing machine is used to sanforize the fabric, and then the fabric undergoes a scutching procedure. Then, a setting machine is used to preset the scutched fabric, the fabric undergoes a dyeing procedure to form an elastic fabric. Then, the elastic fabric undergoes a second scutching procedure and a second setting procedure to form the finished product as the elastic functional textile fabric according to this invention. Through the production method disclosed above, problematic situations like insufficient weft weight, unsmooth fabric surface, pitting surface, uneven dyeing, side shading, poor fastness, chromatic aberration, dyelot chromatism, insufficient elasticity, as well as spray burns, etc can be dramatically reduced.
