Embodiment 1-3 and comparative example 1-2
[0036] Embodiment 1-3 and comparative example 1-2 composite fiber silk layer preparation
[0037] The composite fiber silk layer of the embodiment of the present invention 1-3 and comparative example 1-2 comprises the preparation raw material of following parts by weight, as shown in the table below:
[0038]
[0039]
Embodiment 1-3
[0040] The preparation of embodiment 1-3 composite fiber silk layer is:
[0041] (1) Mix corn bio-based fiber and polycarbodiimide evenly, add it to the preheated Haake torque rheometer RC90 for melt blending, the reaction temperature is 110°C, and the mixer speed is 60r / min , reacted for 25 minutes, and then placed the reaction blended product at 50° C. for 24 hours in vacuum and dried it for later use;
[0042] (2) Mix the reaction blended product obtained in step (1) with polyhydroxyalkanoate and succinic anhydride, place it in a pressure capillary rheometer at 180°C and 7MPa, flow out naturally, cool, and collect filament;
[0043] (3) The filaments prepared in the step (2) are opened, carded, laid, pre-wetted, spunlace, and dried to form a composite fiber layer.
[0044] For the preparation of the composite fiber filament layers of Comparative Examples 1 and 2, refer to the above-mentioned method.
Embodiment 4
[0049] Embodiment 4 preparation of antibacterial fiber non-woven fabric layer
[0050] Using sisal-based antibacterial fiber as raw material, the antibacterial fiber non-woven fabric is made through the acupuncture process. The acupuncture process adopts a continuous working mode. Processed into non-woven fabrics, the needle-punched depth is 12mm, and the density of the non-woven fabric surface is 400g / m 2 , the needling density is 400 pricks / cm 2 .
