PROBLEM TO BE SOLVED: To provide a fiber for an airlaid nonwoven fabric which achieves both uniform opening property and sufficient expression of three-dimensional crimp in an airlaid nonwoven fabric manufacturing process. SOLUTION: This is a fiber composed of a single synthetic polymer or a composite fiber in which two kinds of synthetic polymers are compounded in an eccentric sheath-core type or a parallel type, and has a single fiber fineness of 0.5 to 200 decitex. , The fiber length is 3 to 20 mm, and the number of crimps is 0 It has a zigzag plane crimp with 13 peaks / 25 mm and a crimp rate of 0 to 20%, and the number of crimps is 15 by heat treatment at 60 to 200 ° C. It is based on a fiber for airlaid nonwoven fabric having latent crimping ability to develop a three-dimensional crimp of up to 80 peaks / 25 mm and a crimp rate of 25 to 90%. |
