Zusammenfassung: | The invention discloses a method for producing high-water-absorbability twin-spun non-woven fabric by adding SAP on a twin-spun production line, raw materials comprise wood pulp fibers, melt-blown PP, hydrophilic master batches and an SAP material, and the method specifically comprises the steps of raw material standby application, heating melting, spinning forming, embossing and reeling. According to the invention, the SAP material and the wood pulp are jetted on the condensation net curtain during spinning forming by adjusting the process parameters such as the die head angle parameter and the main suction parameter, so that the SAP can be directly and stably added on line, the SAP can be added layer by layer, the added SAP falls into the core layer of the product, and the blanking is balanced and stable, is uniformly distributed and is tightly wrapped. The SAP has excellent water absorption and water retention performance, the hydrophilic master batch can endow the non-woven fabric with efficient hydrophil |
