摘要： Modified cross-section fibers for artificial hair having an improved bulkiness and a soft feeling as compared with conventional fibers for the artificial hair, comprising synthetic fibers, the synthetic fiber having a cross-section comprising one central connecting portion and projections extended in three directions from the central connecting portions, wherein at least one of the three projections is most narrowed at a portion where it is nearer from a top edge of the projection than 1/2 of a length R from a center of the central connecting portion to the top edge of the projection, a ratio of W1/W2 wherein W1 is a width of the widest portion in a portion where it is nearer from the top edge than the most narrowed portion, and W2 is a width of the most narrowed portion is 1.05 to 2.0, and a ratio of R/W1 wherein R and W1 are the same as defined above is from 1.10 to 5.0.

摘要： Fiber for artificial hair having an excellent bulkiness and also a soft feeling like the human hair, as compared with conventional fibers, are provided. The fiber comprise synthetic fibers, wherein an apparent bulk specific gravity of the fiber before crimping is within a range of from 0.1 to 0.2, an apparent bulk specific gravity of the fiber after crimping is within a range of from 0.02 to 0.05, a cross-section of the fiber is a modified cross-sectional shape comprising one central connecting portion, and projections extended in at least three directions from the central connecting portion, part of a surface or the entire surface of the fiber is open in the longitudinal direction of the fiber, and the fiber has a single yarn fineness of from 25 to 75 denier.
