Regarding how to design the yarn-cutting process to obviously improve the production efficiency,the article has pointed out the reasonable design schemes based on conventional comparison test and symmetrical analytic method,which directed the direction for the yarn-cutting method of yarn-dyed fabric of symmetrical pattern.

The variation of surface dilatational characteristic parameters with adsorption time for soy 11S globulin adsorption films on air-water interface was measured by the axisymmetric drop-shape analysis,as a function of protein concentration and pH value in the bulk phase.
