Process for producing acrylic fiber

Image Number 4 for United States Patent #4347203.

An acrylic fiber having linen- or cotton-like feeling, dry feeling, a high hygroscopicity and a high water retentivity, which is characterized in that said fiber is covered on the outside with creases running along the fiber axis, adjacent creases being 0.1 to apart on the average; has in any of its cross-sections two or more macrovoids, or more in major diameter, which extend in the direction of fiber axis; and said fiber has 30 to 150 microcrimps per 25 mm of fiber length. A method for producing such a fiber is also disclosed.
