The introduction of the polyether group also increases the antistatic property and easy-to-clean property of the finished fiber or fiber rope.
The shuttle group modified silicone oil refers to polydimethylsiloxane containing a shuttle group in a side chain or a terminal group. The modified silicone oil can improve durability, and particularly has better effect when being used together with amino silicone oil.

For example, the umbrella rope can be treated by preparing a silicone oil microcapsule emulsion with a shell layer of silicon dioxide, and preparing the emulsion with a binder, a penetrating agent and water into an anti-burning agent according to a certain proportion. Silicone oil/silicon dioxide microcapsules are adhered to the surface of the treated rope fiber; for example, polyurea coated dimethicone nanocapsules can be prepared as the silicone oil component of the antipyrotic; for example, calcium alginate coats silicone microcapsules as the silicone oil component of the antipyrotic.
As an alternative embodiment, the modified silicone oil can be prepared into a microcapsule form for use.
In an alternative embodiment, the particle size of the microcapsules is set to 50 to 150 nm. Further as an optional embodiment, the nano-microcapsule with the particle size of 100-150 nm is selected.
Further, as an alternative embodiment, a proper amount of nano carbon material, such as at least one of nano modified graphite, nano carbon black or graphene, can be added into the anti-burning agent, so that the heat conduction and the electric conduction performance of the fiber rope are increased, the surface friction resistance of the fiber rope is reduced, static electricity is prevented, the anti-burning performance and the durability of the fiber rope are improved, and the service life is prolonged. In an alternative embodiment, the amount of the nanocarbon material is set to 3 to 8% by mass.
As an alternative embodiment, anionic penetrants may be chosen as penetrants, e.g. RCOO-, -SO3ˉ、-OSO3ˉ、-PhSO3ˉ、-OPO3-a-component; as an alternative embodiment, a non-ionic surfactant, such as a polyoxyethylene ether surfactant, may be selected.
As an alternative embodiment, ethyl acetate or the like may be selected as the binder.
