The Janesville Cotton Manufacturing Company was established in 1874 in Janesville, Wisconsin. The production of fabric occurred in a three story building with 125 mill hands and 200 looms and was the only factory of its kind in the western U.S.

A group of investors from Cincinnati, Ohio purchased the company and changed its name to Janesville Cotton Mills Company. New fiber lines were installed to produce batting for automobiles and furniture.

Janesville Acoustics launched its first Aerotex TM Underbody Panel in Columbus, MS on the Chrysler LX program. Aerotex is a lightweight, acoustical, temperature resistant, structural fiber alternative to plastic.
