Simple and rapid mechanical degumming production equipment and technology of ramie

Abstract

The invention discloses simple, quick and mechanical degumming production equipment for ramie. The equipment mainly consists of a ramie softening machine, an immersion device, a degumming fiber opener, an edulcoration fiber opener and a washing fiber opener, wherein the outlet of the ramie softening machine is formed above the immersion device; a feeding roller is arranged between the immersion device and the degumming fiber opener; a transferring roller is arranged between the degumming fiber opener and the edulcoration fiber opener; and a pulling roller and a conveying roller are arranged between the edulcoration fiber opener and the washing fiber opener. The invention also discloses a simple, quick and mechanical degumming production process for ramie. Mechanical degumming, fiber opening and arranging mainly based on a main physical method are performed on ramie raw materials which are subjected to low-bath-ratio impregnation pretreatment through a mechanical outer force and auxiliary treatment, so that energy conservation, emission reduction, consumption reduction and clean production during degumming can be realized.

Description

technical field [0001] The invention relates to the field of ramie fiber production, in particular to a simple and rapid mechanical degumming production equipment for ramie and a process thereof. Background technique [0002] Raw ramie is the bast layer of the plant obtained by stripping and scraping the green after crop harvesting. Its main components are pectin, cellulose, hemicellulose, lignin, ash, etc., which must be removed by biological, chemical, and mechanical means. Glue substance, extract pure ramie fiber. Usually, the traditional ramie production process adopts the chemical method of strong acid, strong alkali, high temperature, and high pressure to remove the colloidal substance and prepare the fiber. The surface structure causes great damage, and it is difficult to improve the fiber quality and the added value of textile products. [0003] Although the disclosed ramie biological degumming technology has greatly reduced the consumption of water and chemical ma...

Problems solved by technology

However, the current two types of biological degumming technologies, no matter whether they use self-selected degumming strains to add bacteria to degumming, or directly use biological enzyme degumming agent production processes, require high personnel quality, technology, and environmental conditions. The consumption of electricity and coal is large, and the degumming is systematic. higher production costs

And for the degumming bacteria process, in addition to the above-mentioned common shortcomings, there is also a whole set of equipment that has increased the degumming bacteria strain selection, cultivation, storage, purification, and step-by-step expansion. The equipment investment is large, and the degumming bacteria cultivation process Complexity, long cycle and other issues to be improved, the removal rate of pectin is generally 70-80%, and a large amount of gum remains, which still needs chemical refining

The biggest feature of the biological enzyme degumming process is that it is easy to operate, but the cost of using a degumming agent is high, the removal rate of pectin is low, and the degumming effect is unstable. Therefore, the biological degumming technology needs to be further improved and perfected. Widely accepted by enterprises
