Embodiment 1
[0021] The present invention proposes a hydrophilic and lipophilic medical sheath-core fiber nonwoven fabric. The medical sheath-core fiber nonwoven fabric is prepared by processing sheath-core fiber through a spunlace process. The sheath-core fiber It includes a core layer and a skin layer, the core layer is modified polyester fiber, and the skin layer is modified polylactic acid fiber.
Embodiment 2
[0023] The present invention proposes a hydrophilic and lipophilic medical sheath-core fiber nonwoven fabric. The medical sheath-core fiber nonwoven fabric is prepared by processing sheath-core fiber through a spunlace process. The sheath-core fiber It includes a core layer and a skin layer, the core layer is a modified polyester fiber, and the skin layer is a modified polylactic acid fiber;
[0024] Wherein, the preparation of sheath-core fiber is as follows:
[0025] S1, core layer material modification: dry polyethylene terephthalate polyester chips, then add montmorillonite, carbon nanotubes, silane coupling agent to it and mix, the polyester chips, montmorillonite, The weight ratio of carbon nanotubes and silane coupling agent is 100:12:1:2, adding them into a twin-screw extruder, melt blending, extruding and granulating to obtain modified polyester chips;
[0026] S2. Melt preparation: Dry polylactic acid chips and modified polyester chips separately, dry polylactic aci...
