  • The Fundamentals of Air-Jet Texturing

    Overfeed is the governing factor in the process of air texturing. The influence of change in overfeed on the final textured yarn properties is greater than that of any other processing parameter or supply yarn parameter. The role of water is to combine filaments, thereby presenting fewer free …
