Description
Technical Field
The invention relates to the technical field of synthetic leather, in particular to a manufacturing method of superfine fiber clothing leather.
Background
The sea-island type superfine fiber is a main stream material of superfine fiber clothing leather because the single filament number is far smaller than that of common fiber, and toluene is usually used as an extraction solvent in extraction because the sea component of the sea-island type superfine fiber is Low Density Polyethylene (LDPE) and the characteristic that polyethylene can be dissolved in hot toluene and cotton fiber is insoluble is utilized. Regarding toluene extraction, patent document 1 (CN 112626758 a) discloses a toluene extractor for microfiber base cloth, which realizes extrusion of base cloth by arranging a large extrusion roller in cooperation with a plurality of small steel rollers when toluene extraction is performed on microfiber base cloth, and a plurality of slots are formed in the inner side of the large extrusion roller, so that extruded PE solution can be stored in the slots, and then PE solution is discharged from the center of the large extrusion roller from slot joints, so that the usage amount of toluene can be reduced. However, the toluene extraction mechanism has more compression rollers which pass through, and the melted polyethylene is extruded out by a mechanical compression rolling mode when the base cloth is compressed and rolled, and meanwhile, the base cloth is excessively stretched in the warp direction by the transmission mode of the base cloth, so that the production of superfine fiber clothing leather is not facilitated; in addition, patent document 2 (CN 100487190C) discloses a method and a device for extracting resin from sea-island fiber, which considers the problem of overlarge radial stretching of the base cloth caused by friction force, and is provided with a negative pressure extraction roller with a negative pressure area, and by arranging a plurality of through holes on the surface of the roller and arranging a negative pressure suction pump inside the roller, the base cloth is adsorbed on the negative pressure extraction roller, further, the relative sliding of the base cloth is prevented, the problem of overlarge radial stretching of the base cloth is avoided, meanwhile, toluene is promoted to pass through the base cloth in a negative pressure mode, and the dissolved resin is taken away from the sea-island fiber, but the solvent is mainly acted by the negative pressure, compared with the extrusion times required by mechanical extrusion, and meanwhile, the extracted solvent is not acted by the negative pressure to improve the efficiency and effect of resin extraction, in addition, because the base cloth is adsorbed on the extraction roller, the base cloth at the same place always passes through the through holes, so that the base cloth is not fully processed, and in addition, the base cloth needs to be transited when being switched between a free state and a negative pressure adsorption state, if the base cloth is required to be pulled, and the base cloth is possibly damaged if the state is suddenly switched; finally, the applicant has also applied for a clothing leather production process, such as patent document 3 (CN 102965967 a), and the superfine fiber synthetic leather is obtained by multilayer compounding and then peeling operation, but in the process of extracting the base cloth, the existing toluene extraction device is still used, the extraction efficiency is low, more toluene is used, and the obtained synthetic leather is greatly affected by the extraction process.
In view of the foregoing, in the prior art, there is a strong need for an improved toluene extraction process for manufacturing ultrafine fiber clothing leather, in which the toluene extraction process related to the prior art is a method of performing roller extrusion in toluene solution or polyethylene extrusion using negative pressure, which can reduce the use of equipment and improve the efficiency of the extraction equipment compared with the general toluene extraction equipment, but there is no manufacturing method of improving the polyethylene removal efficiency by using negative pressure and mechanical roller extrusion together, and in addition, there is no manufacturing method of manufacturing ultrafine fiber clothing leather capable of spraying toluene solution combined with mechanical extrusion and backflow onto the outer surface of a base fabric and combining with negative pressure to adsorb the inner surface of the base fabric and performing ethylene removal on the whole aspect of the base fabric.
