- the production method of the present invention it is preferable to irradiate the surface of the fiber material with atmospheric pressure and low-temperature plasma while moving the fiber material with the inorganic material attached to the surface via an air flow.
- preferred examples of the inorganic material include titania, alumina, and ceramics.
- natural fiber or synthetic fiber can be used as the fiber material, and among them, powder or fine fiber made from feathers and straw, silk thread, wool, cotton, hemp, pulp Alternatively, synthetic fibers, particularly feathers can be preferably used.
- the surface-modified fiber material of the present invention is characterized by being manufactured by the above-described manufacturing method of the present invention.
- titania is used as the inorganic material that adheres to the surface of the fiber material by a sol-gel reaction.
- a sol-gel reaction of the titanium compound while moving the fiber material through an air flow will be specifically described.
- the titania is adhered to the surface of the fiber material while moving the fiber material through an air flow, so that the entire fiber material can be uniformly treated, and in the fiber material, particularly natural fibers. Since surface modification can be performed while maintaining the original shape and characteristics of the material, it is possible to obtain a high-quality surface-modified fiber material. Therefore, by using the surface modified fiber material obtained by this embodiment as a raw material, it is possible to realize a surface modified fiber product having high added value utilizing its functionality.
- the adhesion treatment of titania (TiO 2 , molecular weight 79.87) to the fiber material surface in this embodiment is specifically, for example, titanium tetraisopropoxide (TTIP, molecular weight 284.22) as a titanium compound. And can be carried out according to the following sol-gel reaction. Ti ⁇ OCH (CH 3 ) 2 ⁇ 4 + 2H 2 O (water vapor) ⁇ TiO 2 +4 (CH 3 ) 2 CHOH

- the titania produced by the sol-gel reaction can be adhered to the surface of the sol-gel.
- the titania attached to the fiber material surface can be more firmly fixed to the fiber material surface, and the titania can be more reliably prevented from peeling off during handling after the surface modification.
- the functionality imparted to the natural fiber can be maintained for a long time.
- the atmospheric pressure low temperature plasma is a plasma generated under atmospheric pressure and at a room temperature of about 40 ° C. or less.
- atmospheric pressure low temperature plasma is used for processing the fiber material, it is possible to reduce the equipment cost and processing cost because no pressure reduction is required, and it is possible to perform processing at room temperature. Therefore, the shape and characteristics of the fiber material that is the object to be processed are not impaired.
