Abstract

955,903. Stretching nylon filaments. MONSANTO CHEMICAL CO. March 26, 1962 [April 10, 1961], No. 11464/62. Heading B5B. Nylon filaments capable of being molecularly oriented are fed to a first stretch zone at a predetermined rate, withdrawn from the zone at a predetermined increased rate, the movement of the filaments through the zone being snubbed so that there is a tendency for the point of the necking down of the filaments to be localized. The filaments are then passed through a second stretch zone maintained at 130‹ to 220 ‹ C. and withdrawn therefrom at a predetermined increased rate, whereby the filaments are stretched a second time, the movement of the filaments through the second zone being snubbed and the filaments being heated at the same time, the overall draw ratio employed being 2.5-5.5 and the draw ratio employed in the second stretch zone being 1.2-1.9. Finally the filaments are heated under low tension permitting them to shrink 6-10%, and are then taken up in an orderly manner by conventional means. The filaments may be snubbed in the first zone at 20-85‹ C. The draw ratio employed in the second stretch zone may be 1.4-1.7. The nylon may be nylon-6 or nylon-66.
