processes for spinning and drawing polyamide filaments are known for example from u s pat nos 3 414 646 3 761 556 and 4 396 570 hereby incorporated by reference polyamides are well known under the generic term 34 nylon 34 and are long chain synthetic polymeric amides nylons are identified by the number of atoms in the diamine and dibasic acid for example nylon 6 6 which stands for a polymer formed by the condensation of hexamethylene diamine and adipic acid other nylons are formed from only one reactive species such as an aminoacid or a lactam polyaminocaproic acid is produced by the polymerization of caprolactam and is known as 34 nylon 6 34 commercially available and useful for the purpose of this invention are all linear melt spinnable polyamides preferred for the purpose of this invention are nylon 6 nylon 66 nylon 6 10 nylon 6 12 nylon 11 nylon 12 nylon 66t nylon 6i6t copolymers thereof or mixtures thereof and especially preferred is nylon 6 in step a the polyamide is melted in an extruder and spun through a spinnerette to form filaments these filaments are quenched in step b with a flowing quench medium such as air in step c a yarn.
