    Abstract: PROBLEM TO BE SOLVED: To provide a polyamide fiber structure having excellent see-through preventing properties, and excellent yellowing resistance, fastness against transition of dyeing and washing fastness even in a fabric dyed to a light color such as whitish color, skin color, yellow, pink or cream-color, and a method for manufacturing the same. SOLUTION: The yellowing-proof polyamide fiber structure is a knitted fabric of an elastic yarn and a core-sheath type conjugate yarn whose core part contains a white pigment. The knitted fabric is treated with an aqueous medium containing an acid anhydride, dyed and treated for finishing. The resultant fiber structure has a yellowing factor with vanillin ΔYI of =40.

    Abstract: PROBLEM TO BE SOLVED: To provide a method for dyeing and finishing fibers capable of dyeing and finishing the fibers in high quality with reducing quantity of water to be used and quantity of waste water. SOLUTION: This method for dyeing and finishing fibers is, in the dyeing and finishing process carried out by dissolving or dispersing a fiber-treating agent in a solvent, to use a regenerated solvent obtained by regenerating a used solvent generated in the dyeing and finishing process in at least 40% of the solvent and the regenerated solvent has
