Example Embodiment
[0016] Example 1
[0017] S1: The fine fiber polymer includes low melting point chemical fiber, carpenter fiber and wood pulp. Low melting point chemical fiber: wood pulp fiber: carpenter = 5:3:1. The mixture of fine fiber polymer and binder fiber is made of a large screw High temperature melt extrusion, heating temperature is 260℃, to obtain polymer A in molten state;
[0018] S2: The polymer A is spun at a pressure of 4.8MPa through an extruder, and the spun yarn is stretched through the stretcher to form a fiber drawing B, which is guided to the soaking liquid for soaking for 4h, and then directed to air-laid On the machine, the composition of the soaking liquid is 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 B is laminated on the web forming machine, guide the laminate to the hot rolling mill for hot rolling. During the hot rolling, the surface of the fib...

[0021] Example 2
[0022] S1: The fine fiber polymer includes low melting point chemical fiber, carpenter fiber and wood pulp. Low melting point chemical fiber: wood pulp fiber: carpenter = 5:3:1. The mixture of fine fiber polymer and binder fiber is made of a large screw High temperature melt extrusion, heating temperature of 280℃, to obtain polymer A in molten state;
[0023] S2: The polymer A is spun at a pressure of 5.3 MPa through an extruder, and the spun is stretched through the stretcher to form a fiber drawing B, which is guided to the soaking liquid for soaking for 8 hours, and then directed to air-laid On the machine, the components of the soaking liquid are as follows: 40 parts of astragalus extract, 40 parts of acrylate, 0.02 parts of triclosan, and 40 parts of ethylene glycol;
[0024] S3: When the four-layer fiber drawing B is laminated on the web forming machine, guide the laminate to the hot rolling mill for hot rolling. During the hot rolling, the surface of the fi...
