High inertia, it is therefore desirable to its surface be handled to improve fiber surface activity.At present carbon fiber surface treatment method compared with
It is more, especially with solution oxides such as anodic oxidations using in the majority, meeting residual solution after surface oxidation treatment, thus washed
Processing removes fiber surface residual solvent, washing and drying is then carried out, in order to subsequent sizing technique.
The most commonly used method of carbon fiber surface washing and drying is that processing, such as Publication No. is dried in blowing-type drying oven
It is real by heated-air drying mode that the Chinese invention patent document of CN102645091A discloses drying device etc. after carbon fiber is washed
Existing fiber surface drying.But for high-strength high-modules carbon fibre, since high brittleness is presented in fiber, in process of production by
It is easily formed surface lousiness in reasons such as tension drafts, if washing and drying easily causes fiber surface using heated-air drying mode
Lousiness aggravates, and then influences the mechanical property of fiber.
It is done for the washing of carbon fiber in addition, the Chinese invention patent document of Publication No. CN107385735A is disclosed
The system of dry, starching and dryness finalization, using hot-rolling contact furnace drying method, although this method can fast implement carbon fiber baking
It is dry, but since fiber surface is thermally contacted with hot-rolling, cause the active group of carbon fiber surface generation after surface treatment to be sent out
Raw damage, fiber surface activity decline so that surface treatment loses meaning.
Carbon fiber product UV curing disclosed in the Chinese utility model patent document of Publication No. CN201122045Y
It is proposed to utilize ultraviolet light or infrared light mode of heating in equipment, but its there are following two points essence is different from the present invention：First, answering
With field difference, patent be dried using infrared lamp and quartz burner for carbon fiber product it is ultraviolet on product
Line coating, the present invention are happened in carbon fiber production process, are dried for fiber washing；Second, apparatus structure is totally different, energy consumption is poor
