Abstract

The invention relates to a dyeing and finishing technology of real silk / T400 fabric employing a one-bath one-step process. According to the provided technology, degumming of real silk can be finished in a high-temperature dyeing process. The technology has the characteristics that the technological process is short; the real silk is slightly stained or not stained and is not damaged. According to the technical scheme, the dyeing and finishing technology of the real silk / T400 fabric employing the one-bath one-step process sequentially comprises the following steps: (1) pretreatment; (2) degumming of the real silk, dyeing in one bath, and dyeing formula; (3) soaping or reductive cleaning; (4) washing; (5) drying; and (6) thermoforming.

Description

technical field [0001] The invention relates to a novel elastic fabric dyeing and finishing process, in particular to a one-bath one-step dyeing and finishing process (that is, degumming and dyeing in the same bath) of a latitudinal elastic fabric formed by interweaving real silk and T400. Background technique [0002] Silk is a natural protein fiber, known as the "fiber queen" and "the second skin of the human body". It not only has a soft and elegant appearance, but also has the inner quality of skin care and health care, and has advantages that other fibers cannot match. [0003] Clothes containing elastic fibers not only fit the body shape, but also show beautiful natural curves and increase the aesthetic feeling; they will not restrict the activities of the human body and meet people's requirements for comfort. T400 is a new type of composite elastic fiber, which is made of parallel composite spinning of PET and PTT. It has permanent spiral crimp, excellent bulk, elasti...
