Automatic production process for preparing fibers by combining ramie finishing

Abstract

The invention discloses an automatic production process for preparing fibers by combining ramie finishing. The process comprises the following steps of: (a) feeding a ramie raw material into a softening machine, removing partial impurities by mechanical kneading, and then coiling the strip-like ramie raw material into a dipping barrel; (b) pushing the dipping barrel into a bast fiber pretreatmentmachine, performing vacuum pretreatment, pushing out the ramie raw material and storing the ramie raw material for 2 to 3 hours to finish dipping treatment of the ramie raw material; and (c) and sequentially performing degumming and fiber opening, impurity removal and fiber opening, washing and fiber opening, bleaching, rinsing, oil supply softening and trembling on the dipped ramie raw material by using a degumming and fiber opening machine, an impurity removal and fiber opening machine, a washing and fiber opening machine, a bleaching machine, a rinsing machine, an oil supply softening machine and a trembling machine respectively. By the process, continuous mechanical production of the whole degumming process can be realized, and the purposes of saving energy, reducing emission, reducing consumption and improving the quality of the fibers are fulfilled.

Description

technical field [0001] The invention relates to a bast fiber production process, in particular to an automated production process of ramie scouring and fiber-making. 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, chemical degumming of ramie uses more than a dozen processes including strong acid, strong alkali, high temperature, and high pressure to produce fibers, and these processes are independent of each other. Semi-finished products need manual and semi-mechanical loading and handling, which is labor-intensive. , more labor, poor production environment, serious environmental pollution, and great damage to the fiber surface structure, it is difficult to improve product quality. Though t...

Problems solved by technology

However, the current two types of biological degumming technology, whether using self-selected degumming strains and degumming bacteria, or directly using biological enzyme degumming agent production technology, have high requirements for personnel quality, technology, and environmental conditions, and the consumption of electricity and coal is large. Degumming system The permanent production cost is relatively high, and most of the processes still use the traditional chemical degumming production process, and continuous production has not been realized

Although some enterprises can use the degumming bacteria process to carry out the large-scale production of ramie biological degumming at present, and its product quality is also relatively stable, but in addition to the above-mentioned common deficiencies, there are also increased degumming bacteria breeding, cultivation, storage, A complete set of equipment such as purification and step-by-step expansion of cultivation requires a large investment in equipment, and the cultivation process of degumming bacteria is complex and long-term, and there are still problems such as discontinuity between the entire degumming production process. The removal rate of pectin is generally 70-80%. , there is still a large amount of colloid remaining, and chemical refining is still needed

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.
