PURPOSE:To obtain a dyed product having high fastness excellent in hand and body by homogeneously applying a white slurry of kaolin to a natural fiber product, drying the product, then subjecting the dried product to fixing treatment with an organic acid alumina compound and subsequently dyeing the resultant product according to a conventional method. CONSTITUTION:A white slurry of kaolin after removing iron causing a difficulty in dyeing is homogeneously applied to natural fiber (e.g. cotton, hemp, silk or wool) by dipping, etc., to carry out pretreatment. The pretreated fiber is then dipped in a fixing agent solution composed of an organic acid alumina compound, subjected to steaming treatment and then dyed with an acid dye, direct dye, etc., according to a conventional method. A bright dyed product, good in hand and excellent in fastness is obtained by the above-mentioned method, which is especially suitable for black dyeing. |
