Preparation And Properties Of Cellulose Membranes Wrinkle Regeneration

The cellulose pulp were dissolved using LiCl/DMAc system, alkaline system and ionic liquid. The crosslink agent and catalyst were added into the solution. The cellulose membranes were prepared from the cellulose spinning solution. The structure and properties of the cellulose films was characterized by Fourier infrared spectroscopic analysis, tensile strength test and angle of recovery test. The factors affecting the recovery angle and tensile strength were investigated. The result showed that the optimum conditions were as follows:1%BTCA, cured at180℃for3min.The cellulose membranes were prepared from the cellulose spinning solution. The structure and properties of the cellulose films was characterized by Fourier infrared spectroscopic analysis (FT-IR), tensile strength test and angle of recovery test. The result showed that the anti-crease property of cellulose film was improved and the crosslinking reaction was proved by FT-IR. And the recovery angle of cellulose film was significantly improved.
