Abstract:

In order to discuss the influence of different micro-dissolve methods and activation for the tensile properties of hemp/cotton blended fabric,treated fabrics and hemp fibers with pretreatment and LiCl/DMAc micro-dissolution .LiCl/DMAc is a kind of stable and green dissolve system, the design of the micro-dissolution was LiCl/DMAc solvent with 10% percent and temperature was 65℃. Fibers were analyzed with FT-IR and XRD methods,tensile properties of fabrics were tested by Instron.The result shows that the main groups have no obvious changes in fibers,cellulose derivative reaction has not be found during micro-dissolution.Tensile property increases in different degrees with different micro-dissolve processing system. After alkali activation and LiCl/DMAc micro-dissolution , the breaking strength are improved most by 44.5%.
