The Stoddard board said it had been unable to secure funding to ensure the continuing operation of the company.
The Kilmarnock-based operation had employed over 500 people, but lost more than £6m in 2003, the last year for which figures are available.
The firm made carpets for the film Titanic and the red carpet used on the Queen's wedding day in 1947.

"Our first task is to determine whether it is possible to continue trading for sufficient time to identify and conclude a sale to a suitable buyer."
Shares in the company fell from 8p in 2002 to 0.87p before they were suspended on Thursday.
