Process and Dyeing Equipment for Dyeing Wool Yarn with Reactive Dyes

Abstract

The invention provides a process for dyeing wool yarn with reactive dyes and dyeing equipment thereof, belonging to the technical field of dyeing. The method solves the technical problems of low efficiency and high cost of dyeing equipment in the existing process of dyeing wool yarn. The process for dyeing wool yarn with reactive dyes includes a, preparing raw yarn; b, preparing dye solution; c, preparing nonionic active agent; d, dyeing; e, de-drying; f, reclaiming nonionic active agent; g, drying; h, inspection; i, packaging. The dyeing equipment includes a frame, a dye vat and a dehydrator. There is a circulating pump in the dye vat, a heating pipe is fixed on the inner wall of the dye vat, and a ph value adjustment port is provided in the dye vat. A valve and a second valve, a third valve is provided at the ph value adjustment port, the other end of the third valve is connected with the regulating device, and the other end of the second valve is connected with the recovery device. The invention has the advantages of high production efficiency, low cost and the like.

Description

technical field [0001] The invention belongs to the technical field of dyeing, and relates to a process for dyeing wool yarn with reactive dyes, in particular to a process for dyeing wool yarn with reactive dyes and a dyeing device thereof. Background technique [0002] At present, there are segment dyeing process and spray dyeing process on the market to dye wool yarn with different colors. The segment dyeing process or spray dyeing process has the following disadvantages: 1. Both the segment dyeing process and the spray dyeing process require Special equipment is used, the liquid retention rate is high, the excess dye needs to be washed with a large amount of water, and the chroma and COD of the wastewater are high, resulting in very high production costs; 2. The dyeing process is long, the efficiency is low, and the industrialization cost is high; 3. The fabrics made of yarns dyed by the segment dyeing process and the spray dyeing process all have regular color arrangemen...

Problems solved by technology

[0002] At present, there are segment dyeing process and spray dyeing process on the market to dye wool yarn with different colors. The segment dyeing process or spray dyeing process has the following disadvantages: 1. Both the segment dyeing process and the spray dyeing process require Special equipment is used, the liquid retention rate is high, the excess dye needs to be washed with a large amount of water, and the chroma and COD of the wastewater are high, resulting in very high production costs; 2. The dyeing process is long, the efficiency is low, and the industrialization cost is high; 3. The fabrics made of yarns dyed by the segment dyeing process and the spray dyeing process are all arranged in regular colors, resulting in a dull shape

[0004] Although the dyeing equipment disclosed in this patent can make the core of the dyed product to be colored at the same time, so that the color adhesion is stronger, but the dyeing equipment does not have a recovery device, and the non-ionic active agent cannot be recovered, and the resource utilization rate is low. Therefore, , it is necessary to design a dyeing equipment
