Editing Modacrylic (section)

==Production==

Modacrylic fibers are modified acrylic fibers made from acrylonitriles, but larger amounts of other polymers are added to make the copolymers.

The modacrylic fibers are produced by polymerizing the components, dissolving the copolymer in [[acetone]], pumping the solution into the column of warm air (dry-spun), and stretching while hot.<ref name="Kadolph" />

Modacrylics are creamy or white and are produced in [[tow (fibre)|tow]] and staple form.  If looked at in cross section views they have an irregular shape.  Modacrylic fibers are also produced in many different lengths, crimp levels, [[Units of textile measurement#Denier|deniers]] and they can have various shrinkage potentials.

Current modacrylic fiber producers include [[Kaneka Corporation]] in Japan.<ref>{{Cite web |url=http://www.kaneka.co.jp/kaneka-e/business/fibers.html |title=Synthetic Fibers {{!}} KANEKA CORPORATION<!-- Bot generated title --> |access-date=2008-03-27 |archive-url=https://web.archive.org/web/20080501211612/http://www.kaneka.co.jp/kaneka-e/business/fibers.html |archive-date=2008-05-01 |url-status=dead }}</ref>
