A Study on the Spinnability of the Acrylic Fiber

This investigation aims to evaluate the quality of high bulky domestic acrylic tops by comparison of spinnability and mechanical properties of the yarn with which of foreign acrylic tops. The results are: 1. Domestic acrylic tops are acceptable in breaking strength, uneveness, count variation of the yarn but it shows higher shrinkage variation than foreign products more or less. 2. The adquate spinning limit of 3 denier 8 inch staple is considered 60 in metric count. 3. No significant friction on coefficient difference between domestic and foreign products were found and sharp increase in hydrodynamic friction is shown at the speeds of about 10 m/min.
