Abstract

1,206,904. Stretching polyamide filaments. FARBENFABRIKEN BAYER A.G. 9 May, 1969 [1 June, 1968], No. 23709/69. Heading B5B. Melt-spun polyamide monofils are stretched at a ratio of 1: 4À5 to 1: 6À5 within a time of 3-10 seconds while the monofils are in contact with a temperature 25-35‹ C. below the crystallite melting point of the unstretched polyamide as measured by differential thermoanalysis with a heating rate of 4‹ C./min., to obtain a product in which the monofils have a diameter below 1À5 mm. Examples and/or working temperatures are given for polycaprolactam and nylon 11, 12, 6-6, 6-11 and 6-11-12. The products have high linear and knot strength.
