Preferably, the proportion of units derived from hexamethylene-diammonium terephthalate in the ternary copolyamide is 10 to 15%. The diamine constituent of the third component of the ternary copolyamide may be hexamethylene diamine, 3-aminomethyl-3,5,5-trimethylcyclohexylamine - 1, di(4 - aminocyclohexyl) methane or 2,2-bis-(4-aminocyclohexyl)- propane. The dicarboxylic acid constituent of the third component of the ternary copolyamide may be adipic, sebacic or dodecanedioic acid subject to the proviso that if the diamine constituent of the third component is hexamethylenediamine, the dicarboxylic acid is not adipic acid.

The yarn so made is stretched at ambient temperature at a ratio of 4 : 12 by passage over a snubbing pin, and crimp is developed by immersing the yarn in tensionfree state in boiling water. Drawing temperatures up to 70 C. are used in other examples.
