VORTEX SPUN YARN VS. AIR-JET SPUN YARN Dr.N.Ramakrishnan MTech CText ATI (UK)PhD(Cal.‚USA) Abstract Vortex spinning can be viewed as a refinement of jet spinning‚ or a natural development in fasciated yarn technology. As in all other fasciated yarns‚ the structure of vortex yarn consists of a core of parallel fibres held together by wrapper fibres. This has been revealed by examining an untwisted vortex yarn sample under the Scanning Electron Microscope. Subsequently‚ the physical properties

Alpaca fiber is one of the world’s best materials to make yarn. Alpaca fiber is stronger than wool and softer than cashmere. Alpaca yarn is hypoallergenic and doesn’t have the itchiness like other yarns. The alpaca yarn making process is simple with the right steps and the right equipment. First‚ the fleece of the animal arrives at the yarn processing mill and must be washed. As the fleece is put into the washing machine label the different orders so they don’t get mixed up. Normally a natural

directly. So they are first converted into yarns which are longer‚ thicker and stronger. We then use these yarns to make fabrics. The process of making yarns from fibres is called spinning. Here the fibres are not only twisted but also pulled out or drawn. The spinning process helps to hold the fibres together and makes the yarns strong‚ smooth and fine. Then the yarns are now strong enough to make fabric. The whole process of interlacing two sets of yarns at right angles to make a fabric is calledweaving
