One-bath dyeing process and device for viscose/cotton knitted fabric

Abstract

The invention relates to the technical field of one-bath dyeing and discloses a one-bath dyeing device for viscose / cotton knitted fabric. The one-bath dyeing device comprises an external dyeing barrel, the bottom center of the external dyeing barrel is fixedly connected with the shaft end face of the output shaft of a motor, an internal dyeing barrel is mounted in the cavity center of the externaldyeing barrel, a first expansion pipe and a second expansion pipe are respectively mounted on the right wall and the left wall of the axial bottom of the external dyeing barrel, a first mercury thermometer and a second mercury thermometer are respectively mounted in the first expansion pipe and the second expansion pipe, and a cylindrical cavity and an annular cavity between the outside of the internal dyeing barrel and the inside of the external dyeing barrel are respectively provided with a first heating resistor and a second heating resistor. The invention further discloses a one-bath dyeing process for the viscose / cotton knitted fabric. The problem that a one-bath dyeing solution cannot be heated and maintained at constant temperature efficiently simultaneously when the viscose / cottonknitted fabric is dyed by the one-bath method is solved.

Description

technical field [0001] The invention relates to the technical field of one-bath dyeing, in particular to a one-bath dyeing process and equipment for brocade blended fabrics. Background technique [0002] Nylon brocade blended knitted fabrics are widely used as elastic clothing fabrics. In the past, this type of blended fabric was generally dyed by two-bath two-step method, that is, first dyeing viscose fiber with reactive dyes, and then dyeing nylon fibers with acid dyes. Therefore, many dyeing and finishing workers at home and abroad have been committed to the research and production practice of the one-bath one-step dyeing process. [0003] However, when the brocade blended fabric is dyed by the one-bath method, there is a problem that the one-bath method dyeing solution cannot be efficiently heated and efficiently kept at the same time, and there is a problem that the one-bath method dyeing solution cannot be efficiently heated and heated. The problems of high efficienc...
