The Grey Relation Analysis of Hemp Fiber Fineness and Chemical Composition after Plasma Assisted Degumming

The plasma was used to assist hemp fiber degumming. After degumming, the relationship of the hemp fiber fineness and chemical composition was analyzed through the Grey Relation Analysis. The results indicates that pectin content is bigger than hemicellulose and lignin content on the influence of hemp fiber fineness, and the influence of cellulose content is small. This conclusion is consistent with the actual production and the experience of technical personnel.The pectin, hemicellulose, and lignin are therefore the main content to be removed in the plasma assisted degumming.
