Research of the Relationship between Hemp Fiber Disintegration Degree and its Chemical Composition

In order to solve the problem of degumming and short yarn of the hemp fiber, this paper mainly research the relationship between hemp fiber disintegration degree and its chemical composition. Then discuss how the contents of pectin, hemicellulose, cellulose and lignin in hemp fiber could affect the hemp fiber disintegration degree. Calculate and analysis the four factors’ affection degree by Grey Relational Analysis, and build four mathematical models between hemp fiber disintegration degree and each of its content at last. This paper makes a contribution to provide the theoretical basis to the degumming process of hemp fiber and the selection of spinning material.
