    Abstract: PROBLEM TO BE SOLVED: To solve a problem that it is necessary to suppress the radical polymerization of monomers that is a competitive reaction when a graft chain suitable as an adsorption film is formed to a porous film.SOLUTION: The method which introduces a graft chain to a porous substrate including a polymer, includes: an immersion step in which the porous substrate is immersed in a solution including a radically polymerizable monomer; and an irradiation grafting step in which the porous substrate is irradiated in an immersed state, the radically polymerizable monomer is performed with graft polymerization to the porous substrate, and the graft chain is formed to the porous substrate, wherein the solution including the radically polymerizable monomer includes a solvent containing 40-70 vol% of a primary or secondary univalent lower alcohol.

    Abstract: PROBLEM TO BE SOLVED: To provide a fiber material exhibiting a high removing effect for aging odor, particularly a high removing effect for unsaturated aldehydes such as nonenal and octenal, and maintaining the effect, and to provide a method for producing the same.SOLUTION: There is provided a fiber assembly for countermeasure for aging odor. The fiber assembly comprises a fiber composed of a polymeric base material into which a side chain having an amino group as well as a linear alkyl group or an alkanol group having 4 to 20 carbon atoms is introduced . Since the side chain is covalently bonded to the base material by the radiation graft polymerization method, the side chain do not fall out. In addition, the functional group introduced into the side chain is designed for effectively adsorbing an unsaturated aldehyde or an organic acid odor which are representative components of the aging odor, thereby maintaining the initial effect for a long period of time.
