An analysis of the air-jet yarn texturing process. Part 7, The effects of processing parameters on yarn properties

The properties of the supply yam and the processing parameters together determine the final properties of air-jet-textured yams. An investigation is reported on how variations in overfeed, air-pressure, and texturing speed, wet or dry processing, and the use of an impact element each affect the properties of the yam textured . The test plan and the test methods are described, prior to a report of the test results. It is concluded that the test results agree with the predictions made from the postulated mechanism of loop formation.
