Abstract

The invention discloses a dyeing and finishing process of a soft and comfortable all-cotton mechanical four-side spandex yarn-dyed fabric. The dyeing and finishing process sequentially comprises a tube loosening process, a dyeing process, a warping process, a sizing process, a weaving process and an after-finishing process, and the after-finishing process sequentially comprises a singeing process, a loose desizing process, a loose mercerizing process, a super-shrinkage pre-shrinking process, a shaping process, an air softening finishing process and a pre-shrinking process. Under the condition that spandex is not added, the fabric is endowed with warp and weft two-way elasticity, the elastic elongation can reach 10-15%, and meanwhile the recovery rate can reach 75% or above.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to a dyeing and finishing process of a soft and comfortable all-cotton mechanical four-way stretch yarn-dyed fabric. Background technique [0002] Natural comfort is the main goal people pursue for clothing. Natural harmony and unconstraint are important elements of comfort. However, the comfort that people pursue has long been beyond the scope of current clothing ergonomics research. The elastic fabric can adapt to the movement of the human body, stretches and shrinks, is light and comfortable, and can also maintain the beautiful appearance of the clothing, and the knees, elbows and other parts of the clothing will not be deformed and bulged due to long wearing time. Spandex elastic yarn is usually used to give the fabric a certain degree of elasticity. The elastic fabric containing spandex yarn can be divided into warp elastic, weft elastic and warp and weft t...
