Abstract
Process and apparatus for producing a crimped continuous multifilament yarn by the sequential steps of air-jet texturizing to form multiple random filamentary loops, immediately pulling out metastable loops formed in the yarn without heating and without stretching or deforming the yarn filaments, next shrinking and heat setting the yarn at a temperature of about 150.degree.-245.degree. C., and then winding the yarn onto a spool at a predetermined yarn tension. The resulting spooled texturized yarn has valuable properties and characteristics in subsequent processing and textile operations.
