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...
