Abstract

1,261,205. Carbon filaments. MORGANITE RESEARCH & DEVELOPMENT Ltd. 30 Jan., 1969 [2 Feb, 1968], No. 5354/68. Heading C1A. Carbon filaments are produced by a process comprising heat-treating a filamentary material capable of carbonization whilst maintaining its filamentary structure, wherein the said material is a multifilament tow provided with a predetermined amount of twist, and the twisted tow is heated at up to 900‹ C. to remove volatile constituents thereof leaving substantially kinkfree filaments. Typically, a tow of 10,000 filaments has one twist per every 6-24 inches. After' the heat-treatment the filaments may be further processed by the process of Specification 1,256,072.
