Background
The scouring and bleaching of the flax rove is the most critical processing procedure in the flax fiber processing process, and the quality of the scouring and bleaching effect directly influences the quality of spun flax yarns. The traditional flax roving boiling and bleaching method mainly adopts a mode of combining boiling, chlorine bleaching and oxygen bleaching to degrade non-cellulose colloid components among fibers, weakens the connection among fibers in fiber bundles, splits the fiber bundles into finer fibers so as to reduce fiber damage, increase fiber whiteness and spin the flax spun yarns. However, the traditional boiling and bleaching method has the problems of long process flow, high water and energy consumption, serious environmental pollution and the like, and severely restricts the sustainable development of the hemp industry.
Supercritical CO has been used at present 2 And boiling and bleaching the flax rove by using carbon instead of water resources. Supercritical CO 2 The fluid has the dual characteristics of a liquid phase and a gas phase, and is between the liquid and the gas. The low viscosity and high diffusion properties of the fluid enable the fluid to have faster mass transfer and extraction speed, and can effectively penetrate through a solid phase sample for extraction separation. At the same time, in the supercritical state, small changes of pressure and temperature can lead to obvious difference of fluid density, and by controlling the density change of the fluid, the required solvent strength can be obtained, thereby leading to supercritical CO 2 The fluid can change the solvent strength arbitrarily to adapt to different solutes. By supercritical CO 2 As a medium, the whiteness of the flax rove is improved by setting the boiling and bleaching process conditions, but after the boiling and bleaching kettle is used for a plurality of times, a certain amount of residues are attached to the inner wall, and along with the increase of boiling and bleaching times, the residues are gradually increased, and the residues on the inner wall can influence the boiling and bleaching effect of the flax rove.
