The present invention pertains to a rayon yarn for use in an airlaid nonwoven fabric and having an average crimp rate of 15-75%, inclusive. This rayon yarn for use in an airlaid nonwoven fabric is produced by using a method for producing a rayon yarn by discharging viscose from a spinning nozzle into a spinning bath, forming a line of yarn by solidifying and regenerating the viscose, and withdrawing, extending, and scouring the line of yarn, wherein the extension is separated into two stages of extension, the rate of extension in the first extension stage is 30-65%, inclusive, and the rate of extension in the second extension stage is 0.3-5.0%, inclusive. The present invention further pertains to an airlaid nonwoven fabric containing the abovementioned rayon yarn for use in an airlaid nonwoven fabric, and a hydrolyzable paper containing the abovementioned airlaid nonwoven fabric. The present invention provides: a rayon yarn to be used in an airlaid nonwoven fabric, suitable for the airlaying process, and exhibiting a high crimp rate; a method for producing the same; an airlaid nonwoven fabric; a method for producing the same; and a hydrolyzable paper. |
