Embodiment 1

[0020] A kind of method of double spinning nonwoven fabric, comprises the steps:

[0021] (1) Preparation of spray-melted superfine fibers:

[0022] Extruding the melt-processable polymer into filaments, and then using high-speed gas jets to pneumatically thin and cut the filaments to obtain spray-melt ultrafine fibers for use;

[0023] (2) slurry preparation:

[0024] The spray-melted superfine fiber, wood pulp and superabsorbent resin prepared in step (1) are mixed together, stirred evenly, and made into a slurry for subsequent use;

[0025] (3) Forming treatment:

[0026] The slurry obtained in step (2) is introduced onto a web-forming conveyor belt to form a continuous forming fiber web for subsequent use;

[0027] (4) Hot pressing treatment:

[0028] The fibrous web obtained in step (3) is subjected to hot-pressing treatment, and finally, it can be wound up.

[0029] The diameter of the spray-melted ultrafine fiber described in step (1) is 1-5 μm.

[0030] The wood ...
