Application of ramie softener in flogging procedure of degumming process

Abstract

The invention relates to the use of ramie softener, especially the application in ramie boiling off beating process. The softener takes the place of beater to remove the colloid, crumb, rest alkali adhering on ramie fiber. It can decrease the power consumption and labor intensity, increase yield of the product, decrease noise, improves stability and quality.

Description

technical field [0001] The invention relates to the application of a ramie softening machine, in particular to the application in the process of ramie degumming and kneading. technical background [0002] Ramie is the fiber with the best quality in hemp fiber and is one of the important textile raw materials. As a textile raw material, it must be degummed to remove the ramie glue (including hemicellulose, pectin, wood, fats, waxes and other carbohydrates). The process of ramie degumming is generally tying - soaking - cage - scouring - copying hemp (fiberizing) - bleaching, pickling, washing - dehydration - oiling - deoiling - shaking hemp - drying. The process of copying hemp is one of the important processes after ramie scouring. After the ramie is boiled, most of the colloids have been dissolved, but there are still a considerable part of colloids, debris, residual alkali, etc. attached to the hemp fibers, so that the fibers are still bonded together and cannot be separa...

Problems solved by technology

[0006] The quality of the hemp copying machine depends mostly on the workers' working conditions and operating techniques. It needs to be carefully operated at any time to keep the hemp bundles from being too disordered. Therefore, the quality of ramie is easily restricted by human factors, resulting in unstable quality of ramie; The noise of the hemp machine is high (about 103 decibels when the machine is empty), and the workers have been soaked in cold water for many years. The working environment is harsh and the labor intensity is high, especially in the severe cold season. Although the impurities are removed, there is a lot of fiber loss, and the production rate is reduced. At the same time, the water consumption is very large (the water consumption of each machine is not less than 30 tons per hour), resulting in an increase in product costs; The flanging operation of beating and kneading workers destroys the natural straightening state of ramie fiber, making it a chaotic and tangled hemp sheet, which increases the difficulty of the post-processing process.

[0007] Straight kneading machine is to manually feed the ramie from the hemp feeding curtain, through three groups of hammers and water washing in the forward direction, without artificial turning in the middle, uneven distribution of striking points, less striking times, and beating fibers The degree of looseness is poor. If you manually turn up and down and knock again, the number of workers will increase, which will reduce labor productivity, lengthen the process, and increase the floor space. Therefore, it is not widely used at present.

[0008] The three-layer hydraulic flushing machine has a good effect on saving manpower and reducing labor intensity, but the water consumption is large, and the flushing quality is affected by the water pressure. not commonly used

So far, the ramie softening machine has no other use except for ramie softening
