Embodiment 1
[0017] S1: The fine fiber polymer includes low-melting chemical fiber, carpenter fiber and wood pulp, low-melting chemical fiber: wood pulp fiber: carpenter = 5:3:1, the mixture of fine fiber polymer and binder fiber is made by a large screw High-temperature melt extrusion, the heating temperature is 260 ° C, to obtain polymer A in a molten state;
[0018] S2: Spinning polymer A through an extruder at a pressure of 4.8 MPa, stretching the filaments through a stretcher to form a fiber drawing B, and guiding it into the soaking liquid for 4 hours, and then guiding it to air-laid On the machine, the components of the soaking solution are as follows: 30 parts of astragalus extract, 20 parts of acrylate, 0.01 part of triclosan, and 30 parts of ethylene glycol;
[0019] S3: When the three-layer fiber drawing material B is stacked on the web forming machine, guide the laminate to the hot rolling mill for hot rolling. During hot rolling, the surface of the fiber drawing material is ev...
