Method and device for rinsing and softening fiber bundles

Abstract

The invention relates to a method and a device for rinsing and softening fiber bundles, which is characterized in that a rotatably running mesh pedrail is arranged on a stander, and at an input end of the pedrail, fibers are conveyed forwards through a feed roller along with the pedrail, and are carded through a group of splitting rollers arranged at intervals, sprayed with water through a water spray pipe, soaked in hot water in a hot water tank, and conveyed forwards through the pedrail simultaneously; at an output end of the pedrail, water is squeezed from the fibers by a pair of water squeezing rollers, and then the fibers are sent to a cloth arrangement machine; and the zonary fibers are processed into folded fibers through the cloth arrangement machine to fall into a fiber storage box. The invention can be widely used in the processing of washing, softening, bleaching and the like of various degummed bast fibers, grass fibers, leaf fibers and the like.

Description

technical field [0001] The invention relates to a method and equipment for rinsing fiber bundles, in particular to a method and device for rinsing and softening fiber bundles after degumming treatment. Background technique [0002] The main components of bast fiber, especially hemp fiber, are pectin, hemicellulose, cellulose and lignin. Pectin is a nutrient substance for plants to produce cellulose, hemicellulose and other components. It is composed of a mixed chain containing uronic acid rings. It is an acidic mixed sugar. The main component is pectic acid. ) and its derivatives, as well as many other polysaccharides symbiotic with it. Pectin mainly exists in the intercellular layer, which is the bonding substance between cells; at the same time, it also exists in the cell wall, especially the primary wall. Pectin is divided into soluble pectin and insoluble pectin. Lignin is one of the main components of the plant cell wall, and basically exists in the cell membrane and...

AI Technical Summary

Problems solved by technology

At present, trough rinsing is often used in industry to remove colloids, but the fibers are chaotic and cannot be kept straight, which increases the difficulty of subsequent processing, low fiber production rate, and poor cleaning degree, resulting in relatively high splitting of bast fibers. Low

The traditional bast fiber softening method is mostly batch method. After the bast fiber is processed, it is put into the cooking tank for processing. The cleaning is not clean, the production efficiency is low, and the softness is uneven.
