Abstract

DC60 (13/08/41) A membrane of cellulose fibers with varying densities has been revealed. The membrane consists of at least two ordered and repeating sub-sections, where the first is a high-density sub-section and the second is a low-density sub-section. The high-density sub-section consists of cellulose fibers infused with a fluid latent indigenous polymer (FLIP), such as hemicellulose and lignin. The fibers in this high-density sub-section are held together by FLIP bonds, which are formed by the softening and flowing of the FLIP and subsequent fixation of the FLIP between the high-density fibers. The process for producing this membrane involves steps of FLIP infusion, the use of a single-plane conveyor belt with a membrane-tube surface, membrane formation on the belt, and heating the membrane to a specified temperature to soften and flow the FLIP. This FLIP is located in the first part of the membrane on the membrane-tube surface of the conveyor belt. The process of compressing the membrane surface of the conveyor belt to form a membrane involves the process of immobilizing the FLIP substance and creating FLIP bonds between fibers, thus forming the first fiber of the membrane. A membrane of cellulose fibers with varying densities is exposed. The membrane consists of at least two sub-sections arranged in an orderly and repeating manner, where the first is a high-density section and the second is a low-density section. The high-density section consists of cellulose fibers containing a fluid latent indigenous polymer (FLIP) such as hemicellulose and lignin. These fibers in the high-density region are held together by FLIP bonds, which are formed by the FLIP softening and subsequent FLIP immobilization processes between the high-density fibers. The process for producing this membrane includes the FLIP softening stage, the use of a single-plane conveyor belt with a membrane surface, the membrane formation stage on the belt, and the heating of the membrane to a specified temperature to soften and allow the FLIP to flow. This FLIP is the substance in the first section of the membrane. Located on the membrane surface of the conveyor belt, the process involves compressing the membrane surface to form a sheet. This is followed by a FLIP fixation process that creates FLIP bonds between fibers, forming the first layer of the membrane fibers.
