PURPOSE: To obtain the subject crimped yarn which has excellent stretch elongation rate and stretch modulus and can give the woven or knitted fabrics having excellent stretchability, bulkiness and draping properties by crimping aramide fibers through false-twisting above the decomposition-starting temperature and heat-treating under relaxation.

CONSTITUTION: Aramide fibers are false-twisted over the temperature of its thermal decomposition-starting point (over 390°C in m-met-aramide fibers) and heat-treated under relaxation. The aramide crimped yarn of more than 20%, preferably more than 50% stretch elongation and more than 80%, preferably more than 90% stretch modulus is obtained. Non-contact type heaters are used because crimping is performed at a high temperature.
