摘要： An object of the present invention is to provide a method for producing an ultrafine fiber-containing sheet with suppressed yellowing. The present invention provides a method for producing an ultrafine fiber-containing sheet, comprising (a) introducing a substituent having electrostatic and/or steric functionality to a fiber raw material to obtain substituent-introduced fiber; (b) machine-processing the substituent-introduced fiber obtained in the step (a) to obtain substituent-introduced ultrafine fiber; (c) preparing a sheet from the substituent-introduced ultrafine fiber obtained in the step (b); and (d) eliminating at least a portion of introduced substituents from the sheet obtained in the step (c). In a preferred aspect, the substituent having electrostatic and/or steric functionality is a phosphoric acid-derived group, and the method may further comprise, after the step (a) and before the step (c), the step of (e) changing the degree of neutralization of the substituent-introduced fiber or the substituent-introduced ultrafine fiber.

摘要： Ground chitin is rendered dispersible in aqueous medium to form stable dispersions on mild shearing, by pretreating the chitin with an aqueous oxidizing bleach solution. the dispersions, and paper-like structures prepared from them by papermaking techniques, are useful for treating and binding wounds.Operable bleaches include peroxygen bleaches and labile halogen bleaches. Peroxygen bleaches include hydrogen and alkali metal peroxide, alkaline earth and alkali metal perborate, percarbonate, peroxymonosulfate, and bromate. The labile halogen bleaches include alkali metal and alkaline earth hypohalites, and dihalo-s-triazinetriones.
