Abstract

The invention provides an integral method of boiling and dyeing in production of flax, which comprises roving, acid rinsing, chlorite bleaching, oxygen bleaching, rinsing, boiling in poly-sodium acrylate, dyeing by high-efficiency surface tension depressant, penetrant and active dye, finally wet spinning spun yarn. The invention can directly dye in boiling pan after soda boiling and rinsing, and can combine the boiling with the dyeing into a whole. The invention has advantages that after boiling without dying and before spinning into spun yarn, the fibril surface void ratio is big and the gap between fibers is also big, which are convenient for dye molecules to diffuse towards intrafibre, the dyeing time is short, and the rate of dyeing is high; the invention can also save latter cloth dyeing devices.

Description

technical field [0001] The invention relates to a method for flax production, in particular to an integrated method of scouring and dyeing for flax production. Background technique [0002] Flax is an ancient bast fiber crop and oil crop. Flax originated in the Near East and along the Mediterranean coast. As early as the Neolithic Age more than 5,000 years ago, Swiss lake dwellers and ancient Egyptians had cultivated flax and used its fibers to weave clothing. China is mainly distributed in Heilongjiang and Jilin provinces. [0003] The fibers of flax are strong, soft and fine, and have good color and luster. Flax fiber is strong, soft, fine, not easy to rot in water, and has waterproof effect. In addition, it has friction resistance, high temperature resistance, fast heat dissipation, low dust absorption rate, not easy to tear, not easy to burn, no static electricity, acid resistance It has unique advantages such as high alkali and is an important raw material for the l...
