Natural fiber crystal variation modified liquid medium filling and recovery system and method based on paralleled multiple buses and multiple modified kettles

Abstract

The invention provides a natural fiber crystal variation modified liquid medium filling and recovery system based on paralleled multiple buses and multiple modified kettles. The natural fiber crystal variation modified liquid medium filling and recovery system based on the paralleled multiple buses and multiple modified kettles comprises a liquid medium low-pressure mass flow liquid-filling bus, a liquid medium high-pressure small flow liquid-filling bus, a liquid medium low-pressure mass flow liquid-return bus, a liquid medium low-pressure small flow liquid-filling bus, a gas phase balance bus, and n modified kettles which are in parallel connection on the buses, and n >=1. The invention further provides a natural fiber crystal variation modified liquid medium filling and recovery method based on the paralleled multiple buses and multiple modified kettles. The liquid-filling process comprises mass flow balance liquid filling and small flow pressure boosting liquid filling, and the liquid return process comprises mass flow pressure relief liquid return, mass flow balance liquid return, small flow balance liquid return, and cage shift liquid exhaustion. The natural fiber crystal variation modified liquid medium filling and recovery system and the method based on paralleled multiple buses and multiple modified kettles are good in modified effect, small in system energy consumption, and high in production efficiency.

Description

Technical field [0001] The invention relates to a natural fiber crystal change modified liquid medium filling and recovery system and method, in particular to a natural fiber crystal change modified liquid medium filling and recovery system and method based on multiple buses and multiple modification kettles in parallel , Belongs to the field of high-end textile equipment. Background technique [0002] Natural fiber is an important textile material. It has superior characteristics such as moisture absorption and heat dissipation, anti-bacteria and insect resistance, and radiation resistance. However, it also has defects such as hardness, wrinkles, shrinkage, difficulty in spinning, weaving, and dyeing. Using the crystal modification technology to modify the natural fiber, it can not only retain the advantages, but also significantly improve the performance, achieve the effect of easy spinning, easy weaving and easy dyeing, which not only improves the added value of natural fiber,...
