Abstract: This article discusses linen roving efficient and short processing boiling and dyeing technology, by testing analysis of roving scouring and bleaching of semi-product quality standard, roving dyeing effect and dyeing fiber spinnability, drawing the conclusion: The color fastness and color indicators consistent with the traditional process, the percentage of short fiber below 50mm is 33.23%, which is 35.4% lower compared with traditional process; the average length of fiber is 77.4mm, which is 11.2mm higher than traditional process, the fiber length and regularity is better for later spinning process. Moreover, the new technology has dropped the drying and packing steps for spinning mills, rewinding and preprocessing steps before dyeing, the transportation, loading and unloading steps from spinning mills to dyeing mills, which has improved productivity, reduced the pressure on water consumption, energy consumption and waste water treatment.

Key words: linen roving, one bath scouring/bleaching, dyeing of roving, colored spun yarn, high-efficiency ang shortened process
