Be further, in step C, the pulverizing milled processed process of described rice hull carbon is as described below: first, the rice hull carbon after activation is worn into the particle of particle diameter 50 ~ 100 microns through the mode of mechanical mill, then wear into the particle of particle diameter less than 5 microns through the mode of Gas grinding then.
Further, in step D, the detailed process of rice husk powdered carbon being carried out in an acidic solution surface activation process is as described below: rice husk powdered carbon is put into successively the aqueous sulfuric acid of 30% and the aqueous hydrochloric acid of 30% carries out surface activation process.
Be further, in step e, the concrete steps of described interface processing are as described below: be dipped in spirituous solution by rice husk powdered carbon, and add a certain amount of Trimethoxy silane interfacial agents, soak after 24 hours, again with deionized water immersion, Off water, after unreacted Trimethoxy silane is removed.
Further, in step F, after when the rice husk powdered carbon after interface processing being toasted in the environment of 180 DEG C one section, obtain through comminution by gas stream comminution by gas stream the rice husk powdered carbon that particle diameter is less than 100 nanometers.
Further, in step G, described rice hull carbon powder weight ratio is the weight ratio of 15%, PET or nylon or PP is 85%.
Further, in step G, under the hot environment of 250 DEG C, utilize singe screw to cross after PET or nylon or PP being mixed with rice husk powdered carbon and be pumped into functional polyester grain.
Beneficial effect of the present invention: utilize the plastics that the preparation method of these rice hull carbon plastics is worth, because rice hull carbon is originally vesicular structure, and there is high adsorption and dissociation power, therefore, by obtained rice hull carbon plastic spinning and cut cotton, spin into and spin, and make clothes with it, this clothes has very strong adsorb peculiar smell molecule ability, and there is the effect of decomposing peculiar smell, therefore, this clothes has high dehumidifying, adsorb peculiar smell function, in addition, the far-infrared engergy of rice hull carbon itself increases cellular elements hunting speed, therefore can also blood circulation of human body be improved with the clothes that rice hull carbon plastics are made, there is nourishing function.
