Embodiment 1
[0047] The preparation process of 77dtex / 24f skin-core porous anti-mosquito antibacterial polyester fiber is as follows:
[0048] (1) Preparation of sheath-core bicomponent polyester fiber
[0049] The graphene powder is dissolved and mixed uniformly with a coupling agent solution to form an inorganic powder, which is pre-mixed with a dispersant and dried polymer slices in a high-speed mixer, and melt-extruded to obtain a graphene masterbatch.
[0050] Blend 10wt% graphene masterbatch (SE1231 conductive and thermally conductive graphene, particle size is 30mm), 25wt% calcium carbonate masterbatch and polyester chip according to the mass ratio of 1:20:79, as A component; anti-mosquito The masterbatch (the active ingredient is 25wt% polycyclic aromatic ester) and the polyester chip are blended according to the mass ratio of 4:96, as the B component. After the components A and B are dried in a vacuum drum drying oven, the two-component composite spinning technology is adopted, i...
