하이파일직물 등의 단차파일직물에 적합한 아크릴섬유 및 그 섬유를 포함하는 방적사와, 동 방적사를 사용한 파일직물을 제공한다. 아크릴섬유는 단섬유섬도가 1∼7dtex이며, 수축율이 20∼40%, 수축 후의 부풂성이 0.19∼0.30㎣/g인 고수축성 아크릴섬유이며, 또는 단섬유섬도가 2∼7dtex이며, 신도가 50∼70%, 부풂성이 0.19∼0.30㎣/g인 아크릴섬유이다. Provided are an acrylic fiber suitable for a step pile fabric such as a high-pile textile, a spun yarn containing said fiber, and a pile fabric in which said spun yarn is used. In the present invention, the acrylic fiber is a high-shrinkage acrylic fiber having a single-filament fineness of 1-7 dtex, a shrinkage of 20-40%, and post-shrinking bulkiness of 0.19×101-0.30×101 mm3/g; or an acrylic fiber having a single-filament fineness of 2-7 dtex, elongation of 50-70%, and bulkiness of 0.19×101-0.30×101 mm3/g.
