The story
The first president of the company was Edward Freshl.
In October 1928 the corporation was sued by Gotham Hosiery, which charged Holeproof with a patent infringement. At the time Gotham Hosiery controlled the Pointex patents for manufacture of pointed heel hosiery by virtue of the company's purchase of Onyx Hosiery, some years earlier.
Holeproof Hosiery began making nylon hosiery in January 1940, starting production on 8 of its 230 machines. The hose were made of a synthetic yarn composed of derivatives of coal and iron manufactured by Du Pont. As a competitive move Holeproof Hosiery reduced prices on its nylons by up to 15% in December 1956.
Holeproof Hosiery was made a division of Julius Kayser & Company after it was acquired for $13 million in August 1955. Kayser manufactured ladies gloves, lingerie, and hosiery. Holeproof's fixed assets were absorbed by Kayser during a five-year period concluding on June 30, 1960.
