Abstract

The invention provides a cotton yarn dyeing process, and belongs to the technical field of dyeing treatment. A method for dyeing cotton yarns used for weaving a jean fabric comprises the following steps: a, preparing the cotton yarns; b, performing surface treatment on the cotton yarns; c, rinsing the cotton yarns for the first time; d, rinsing the cotton yarns for the second time; e, dyeing the cotton yarns; f, drying the cotton yarns; and g, rolling up the cotton yarns. The cotton yarn dyeing process disclosed by the invention has the advantage of capability of dyeing the cotton yarns used for weaving the jean fabric more effectively.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a dyeing method, in particular to a cotton yarn dyeing process. Background technique [0002] At present, the existing cotton yarn dyeing process is not perfect, and the dyeing vat has a single structure and a single dyeing operation method, which leads to low dyeing efficiency, poor printing and dyeing uniformity, low dye utilization rate, and poor dyeing effect. . [0003] After searching, for example, Chinese patent literature discloses a double-cylinder dyeing machine [patent number: ZL 201310453352.8; authorized announcement number: CN 103526483A]. This double-cylinder dyeing machine includes a dyeing vat and a yarn hanger arranged in the dyeing vat. The dyeing vat is divided into a left cylinder body and a right cylinder body by a partition. It is characterized in that: the center of the cylinder body is provided with a brake The brake chamber is provided with a hydraulic...
