DENIM JEAN FABRIC CLOTH AND METHOD FOR MANUFACTURE THEREOF

WIPO Patent Application WO/2021/115353

A1

Provided are a denim jean fabric cloth and a method for manufacture thereof, said manufacturing method comprising the following steps: spinning recycled cotton; or blend-spinning recycled cotton and organic cotton; or blend-spinning recycled cotton, recycled fiber, and coffee grounds; or blend-spinning recycled cotton, organic cotton, recycled fiber, and coffee grounds; obtaining a secondary spin; warping, penetrating, and dyeing the secondary spin in sequence to obtain a dyed secondary spin; interweaving the dyed secondary spin into a fabric by warp and weft means to obtain an initial jean fabric; singeing, pulling diagonally, and pre-shrinking the jean fabric to obtain a denim jean fabric cloth. Four raw materials are selected for the manufacturing method: recycled fiber, coffee grounds, recycled cotton, and organic cotton; thus pollution in the manufacturing process is greatly reduced; further, by means of the scientifically reasoned proportioning of raw materials, the wear properties of the denim fabric, such as tensile breaking strength, tear strength, color fastness in washing, color fastness in dry cleaning, color fastness in rubbing, and color fastness in exposure to sunlight are maintained at a high level.
