Flour nonwoven fabric production process, the mixing process is actually a process of different components intermolecular chain interdiffusion, restricted interaction between the molecular chains. Intermolecular interaction of chain size, solubility parameter can be used to represent. Symbol solubility parameter of &, his value is the square root of the cohesive energy density per unit volume degrees. In the non-woven flour production process, which is an important value must refer to. The quality of the nonwoven fabric flour compatibility between different components, it can be used directly to measure the difference between the solubility parameter, & closer, he better compatibility. Components of different molecular weight, for closeness & requirements are different, and the closeness between them has a direct impact on the size of the non-woven flour quality is good or bad.
