Abstract

The invention discloses a web spreading method for preparation of a filament non-woven fabric through a wet spinning technique. The method comprises steps as follows: (1), preparation of filament fiber bundles; (2), drafting of the filament fiber bundles; (3), forming of uniform flaky fiber bundles; (4), conveying of the uniform flaky fiber bundles; (5), inclination compensation treatment on the uniform flaky fiber bundles; (6), spreading of a filament fiber web. The invention further discloses a web spreading device. A fiber web forming mechanism used for crossing and stacking the uniform flaky fiber bundles which are to fall on a web curtain in the breadth direction of the web curtain is arranged at an output end of a conveying roller, an inclination compensation mechanism used for transversely drafting the uniform flaky fiber bundles in an inclined state back and forth in the direction opposite to the fiber web forming mechanism when the fiber web forming mechanism moves is arranged between the conveying roller and the fiber web forming mechanism. With the adoption of the method and device, the wet fiber bundles can form a uniform flaky fiber web on the web curtain, wet-process web forming is realized, and the quality of the filament non-woven fabric is effectively improved.

Description

technical field

[0001] The invention belongs to the technical field of non-woven fabric production equipment, and in particular relates to a web laying method and device for preparing filament non-woven fabric by wet spinning technology. Background technique

[0002] Filament non-woven fabrics are widely used in medical and health care, agriculture, industry, automobiles and other fields due to their excellent performance. Compared with short-fiber non-woven fabrics, filament non-woven fabrics can make non-woven fabrics thinner and stronger. At present, the preparation of filament non-woven fabrics mainly includes spunbonding and wet spinning. The filament non-woven fabric is prepared by the spunbond method. After the polymer has been extruded and stretched to form continuous filaments, the filaments are laid into a web, and the web is then self-bonded, thermally bonded, and chemically bonded. Or a mechanical reinforcement method to make the web into a non-woven fabric. T...
