Abstract

The invention discloses a dyeing technology of a cotton linen blend yarn. The dyeing technology comprises the following steps of: preparing; releasing a cylinder; scouring and bleaching; dyeing; fixing color; washing; dewatering; drying; spooling; and packing. The scouring prescription is changed in the dyeing technology of the cotton / linen blend yarn disclosed by the invention, so that the dye-uptake of the cotton / linen blend yarn can be improved; the step of fixing color is increased in the process of dyeing, so that the cotton / linen blend yarn is more stable in color; after the dyeing technology disclosed by the invention is adopted, the dye-uptake can be improved, the color is more stable, the market competitiveness of products can be preferably improved, and the economic benefit can be improved.

Description

technical field [0001] The invention relates to a dyeing process, in particular to a dyeing process of cotton and linen blended yarn. Background technique [0002] At present, hemp products are favored by consumers because of their natural health effects. The fabric woven from high-tech, high-value-added hemp / cotton blended yarn has the characteristics of fullness, thickness, clear texture, good hygroscopicity, mildew and moth resistance, and durability. However, most of the flax / cotton blended yarns on the market are difficult to color and have the disadvantages of poor color stability. Contents of the invention [0003] Purpose of the invention: the purpose of the invention is to overcome the deficiencies in the prior art and provide a dyeing process for hemp / cotton blended yarns with high color uptake and stable color. [0004] Technical solution: In order to solve the above technical problems, a dyeing process of cotton and linen blended yarn according to the present...
