Embodiment Construction

[0009] A flash-explosion hemp degumming technology accompanied by low-temperature treatment is characterized in that the ramie is first soaked at 25°C for 15 hours, and then the ramie soaked in water is put into a tank filled with a percentage concentration of 18% NaOH solution Alkali treatment is carried out in the medium, followed by high-pressure maintenance for ramie, and decompression flash explosion treatment with low-temperature treatment for hemp fibers after high-pressure maintenance.

[0010] The first step: carry out the water treatment process, immerse 30kg of hemp fibers in a tank filled with water, let the water cover the fibers, and soak for 15 hours at a temperature of 25°C. Then remove the fibers from the sink and use a centrifuge to remove excess water.

[0011] Step 2: Alkali treatment is carried out to the fibers soaked in water, and the hemp fibers are put into a tank filled with a percentage concentration of 18% NaOH solution, so that the NaOH solution is...

Abstract

The invention relates to a hemp degumming technology using a steam explosion with a low-temperature treatment and a device. The invention relatest to the hemp degumming technology, in particular to the steam explosion hemp degumming technology, comprising: firstly ramie is marinated for 15 hours in the temperature of 25 deg C; then the ramie which is already marinated by water is put into a groove which contains a solution of NaOH with a concentration of 18 percent to be processed alkali treatment; then the ramie is kept in high pressure; after being kept in high pressure the hemp fiber is processed a decompression steam explosion treatment with the low-temperature treatment. The hemp degumming technology of the invention has the advantages of that a low rate of incomplete glue, light fibre damage, no pollution, reducing cost of degumming, saving degumming time.

Description

technical field [0001] The invention relates to a hemp degumming technology, in particular to a flash explosion hemp degumming technology and device accompanied by low temperature treatment. Background technique [0002] Hemp degumming is a key process for hemp spinning and weaving. Currently, the hemp fibers used in textiles to weave clothing fabrics must be degummed to obtain. Therefore, the degumming process is a key process for hemp spinning, and the quality of the degumming is directly related to the quality of the products in each process in the future. Unlike cotton, wool and chemical fibers that exist in the form of single fibers, the bast fibers of hemp exist in Inside the plant, you want to extract the fiber. The fibers must be separated from the glue-like substances composed of hemicellulose, pectin, lignin, etc., and further separated into single fibers, in order to become excellent spinnable fibers. [0003] At present, the degumming technology commonly used i...
