精梳棉、长绒棉和棉短绒3种棉浆的打浆性能研究
Study on the Refining Performance of Combed Cotton,Long Staple Cotton,and Cotton Linter Pulp
摘要
Abstract
This study investigated the refining performance of three types of cotton pulps,namely combed cotton,long-staple cotton,and cotton linters,and analyzed the refining process,examines changes in fiber morphology and surface characteristics during refining,evaluated the impact of refining degree on specific surface area,and compared the physical properties of paper sheets made from these pulps.The results showed that the beating degree of the three types of cotton pulp increase with the number of refining revolutions.To achieve a target beating degree of 60 °SR,the required refining revolutions for combed cotton,long-staple cotton,and cotton linters were 30 000,33 000 and 23 000 r respectively.When the pulping speed was the same,long-staple cotton exhibited the lowest beating degree and water retention value,the longest fiber length,and the smallest specific surface area,indicating lower levels of hydration,fibrillation,and lateral cutting compared to combed cotton and cotton linters.When the beating degrees of combed cotton,cotton linters,and long-staple cotton were 56.6,60.2,and 59.1 °SR,the tensile index of long-sta-ple cotton(36.2 N·m/g)was about 34%higher than that of cotton linters,the burst index(2.60 kPa·m2/g)was 24%and 65%higher than that of combed cotton and cotton linters,respectively,while the tear index(15.0 mN·m2/g)was 1.9 and 2.4 times greater than those of combed cotton and cotton linters,respectively.关键词
