Abstract: The possibility of feeding false-twist textured yarn in air-jet texturing to obtain a yarn with higher bulk has been studied. Use of a modified false-twist textured feed yarn for air-jet texturing results in a yarn of higher bulk, instability and tenacity but of lower elongation, initial modulus and linear density, as compared to air-jet textured yarns produced from flat feed yarns. The level of bulk can be further enhanced by post heat-setting the air-jet textured yarns made from modified false twist textured yarns, but the resultant yarns have higher instability and inferior tensile properties. Low interfilament friction, low skein shrinkage and higher bulk retraction are desirable in the modified false-twist textured yarn meant for air-jet texturing process.
