生丝抱合与其结构关系的研究

A Study of Reletionship between Raw Silk Cohesion and Structure

通过对生丝结构的测定分析,选择生丝表现空隙率、含胶率、直径和扁平度作为结构参数。研究结果表明:它们与生丝抱合都显著呈线性相关;生丝抱合与结构参数之间建立的多元线性回归方程,拟合密切,具有理论意义;自动缫生丝和立缫生丝的抱合性能存在显著差异,产生差异的主要结构因素是生丝表观空隙率和含胶率。

Through determining and analysing raw silk structure,we choose as structure parameters,itsapparent porosity,sericin content,diameter and flat degree.The results of experiments show thatthese parameters have obvious linear correlation with raw silk cohesion,there are close relationsbetween equations of multivariable linear regression,which are established on the basis of raw silkcohesion and structure parameters,and these equations are of theoretical meaning.There are obvi-ous discriminations between cohesion properties of automatic reeling raw silk and multi-end ree-ling one and the main factors of structure causing the discrimination are raw silk apparentporosity and sericin content.
