Abstract

The present invention discloses a Modal interwoven fabric dyeing and finishing method, which comprises: (1) fore-treatment: carrying out mercerizing water washing; (2) pretreatment: carrying out fibersplitting treatment; (3) ultra-fiber cutting: adding a biological enzyme to a sand washing machine, and carrying out ultra-fiber treatment on the pre-treated Modal interwoven fabric in the sand washing machine; (4) dying: adding an active dye to a dyeing device, and dyeing the cut pre-treated Modal interwoven fabric in the dyeing device; and (5) function finishing. According to the present invention, with the Modal interwoven fabric dyeing and finishing method, the obtained fabric has characteristics of soft surface touch feeling, fluff touch feeling, high strength and high color fastness, and the problems of fuzzing and pilling can be avoided.

Description

technical field [0001] The invention relates to the technical field of fabric printing and dyeing, in particular to a method for dyeing and finishing modal interwoven fabrics. Background technique [0002] The raw material of modal fiber comes from beech wood in Europe. It is a pure natural fiber, which is green and environmentally friendly, and has extremely low environmental pollution. Modal has the characteristics of silver-white luster, excellent dyeability and bright color after dyeing. It is mostly used in fashion fabrics, coats, windbreakers, women's skirts or casual wear. Modal can be blended with other fibers, so that it can be woven into various fabrics to improve the appearance of the fabric. [0003] Before the modal fabric is made into clothing, it needs to be dyed and finished to dye it in various colors, so that the surface of the fabric can achieve better performance. The surface of general fabrics has long fluff, rough hand feeling, will fall off after lon...
