Abstract
533,777. Rubber thread. SHEPHERD, T. L. July 18, 1939, No. 20822. [Class 70] Rubber thread which has a high modulus of elasticity and can be easily woven or knitted is prepared by stretching, drying and vulcanizing a rubber thread at a temperature below the annealing temperature, i.e. below 100‹C. The drying is done at about 65‹C., and the vulcanization at room temperature, being effected by the use of ultra acceleration. The treated thread undergoes a small retraction if heated to annealing temperature after vulcanization. The thread may be formed by extrusion or otherwise of latex into a coagulant or by cutting a sheet formed from latex or slightly masticated rubber. In an example, latex containing sulphur, sodium isopropyl xanthate, diethylammonium diethyldithiocarbamate, zinc oxide, antioxidant and stabilizer is spun into aqueous acetic acid. The coagulated thread is stretched 1000 per cent. and dried at 65‹ C. or 830 per cent. and dried at 80‹C. The dried and stretched thread is wound on bobbins and vulcanized by storage at 20‹C. for three weeks. Specifications 423,997 and 520,095, [Group IX] are referred to.
