[0021] The content of the present invention will be described in further detail below with reference to the accompanying drawings.
[0022] A preparation method of a flax-coated spandex elastic denim fabric, the steps are as follows:
[0023] S1. Flax treatment: select the raw hemp with a splitting index greater than or equal to 250, and beat the raw hemp into hemp; spray the hemp with an aqueous solution containing a wetting agent for humidification; The roving is spun into rovings on a drawing frame; the rovings are sequentially subjected to compound enzyme degumming treatment, storage, acid washing, sub-bleaching, alkali washing, oxygen bleaching, and water washing; the rovings are twisted by a spinning frame to make spun yarns; the flax Spinning yarn for drying and winding; moisturizing for 18-36 hours; a total of 5 draw frames; four enzymes, pectinase, lipase, xylanase, and virilase, are compounded in a ratio of 3:2:1:1 Then, through tertiary fermentation, a degumming en...
