- On February 28th 1935, Dr. Gerard Berchet, a member of Carothers' team, heated together hexamethylene diamine (1,6 diaminohexane, H2N (CH2)6 NH2) with adipic acid (Hexane 1,6 dioic acid, HOOC (CH2)4 COOH) and meta cresol at 215 water distilled off, then the temperature was raised to 255 260 to distil off the cresol in vacuo. He had made Nylon 6,6. By that autumn, the first nylon threads had been spun. With synthetic fibres, chemists could tailor substances with particular properties.
