<p>There is disclosed a high-shrinkage acrylic fiber made of an acrylonitrile polymer comprising acrylonitrile in no less than 50% by weight, wherein a shrinkage rare after dry heating at 130° C. for 10 min without load is 25 to 35% and a difference between the maximum and the minimum of a shrinkage rate after dry heating within a temperature range of 120 to 140° C. for 10 min without load is 8% or less. There also provided a pile composition comprising the high-shrinkage acrylic in 20 to 80% by weight, and a pile fabric prepared from the pile composition.</p> |
