Abstract

The invention discloses an active one-bath dyeing process of wool-flax blended yarns, wherein the process includes the following steps: step 1, yarn pretreatment; step two, yarn dying: firstly, addinganhydrous sodium sulfate and a leveling agent, then dyeing, next adding sodium carbonate with equal amount and equal time, and fixing a color; step three, yarn soaping including water washing, acid and alkali neutralization and soaping; and step four, yarn posttreatment including water washing and drying treatment. According to the active one-bath dyeing process of the wool-flax blended yarns, through the simple pretreatment process, the yarns obtain good affinity moistening effects and the cost of water and electric energy consumption is reduced; in the dyeing process of the yarns, a cottonactive dye is used, neutral salt anhydrous sodium sulfate is used for promoting dyeing, sodium carbonate is used for fixing the color, the amphoteric ion leveling agent is used for improving the isochromatic property of the wool-flax blended product, and the low temperature environment-friendly soaping agent used in the soaping process not only reduces the water and electric energy consumption ofthe whole soaping step, but also makes the whole dyeing process more environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of wool and flax blended yarn dyeing, in particular to a reactive one-bath dyeing process of wool and flax blended yarn. Background technique [0002] Due to the unique appearance, feel and comfort of wool / linen blended yarn, it can be used as an air conditioner in spring and summer, breaking the limitation that wool products are only used in autumn and winter. Research on the same-color dyeing technology for wool and cotton blended products can provide great development prospects for the products. [0003] When wool and linen blended yarn is dyed, the wool in it is partially damaged due to the surface scale layer, the dyeing speed is fast, the dyeing rate is high, and it is easy to dye flowers. Hemp fiber has high crystallinity, good orientation, high degree of polymerization, relatively slow dyeing, and lower exhaustion rate than wool. [0004] Traditional dyeing has its own disadvantages: [0005] Acid...
