This short article shows the world market growth of yarn spinning industry based on the following information: spinning machinery shipments in 2011, yarn output in Q1/2012, and cotton yarn sales volume during 2007-2016.  In addition, new spinning and texturing technology is also included.




ITMF (the International Textile Manufacturers Federation) has published a report showing the amount of spinning machinery shipments in 2011 as follows.  In 2011, world shipments of short-staple spindles increased 15% to a total amount of 14.33 million spindles.  94% of these shipments or 13.46 million spindles went to Asia, in which China shared for 8.90 million spindles (62%), India 2.49 million spindles (17%), Bangladesh 639,000 spindles (4.5%), Turkey 628,000 spindles (4.4%), and Indonesia 517,000 spindles (3.6%).  For shipments of long-staple (wool) spindles, the report shows that shipments in 2011 increased 35% to an amount of 113,250 spindles.  47% of these shipments or 53,750 spindles were sent to Europe and 43% or 49,000 spindles were sent to Asia.  America and Africa shared for 7.7% and 1.8%, respectively.  In terms of investments in open-end rotors, the report says that the shipments in 2011 increased 27% to an amount of 572,250 rotors.  81% of these shipments or 463,250 rotors went to Asia, in which China shared for 388,250 rotors (68%), India 37,750 rotors (6.6%), Turkey 35,250 rotors (6.2%), and Brazil 30,250 rotors (5.3%).


For shipments of draw-texturing spindles, the report shows that shipments of single heater draw-texturing spindles (for polyamide filaments) in 2011 dropped 86% to an amount of 1,824 spindles while shipments of double heater draw-texturing spindles (for polyester filament) increased 45% to an amount of 826,500 spindles.




Another report recently published by ITMF shows that world yarn output in Q1/2012 decreased 7.7%, compared to the last quarter.  But for year-on-year comparison, the output was up by 12%.  In terms of cotton yarn sales volume, a report by Bharatbook.com shows that during 2007-2011 the sales increased 14.4% from 12.2 million tons to 14 million tons.  Among all cotton yarn producers, China has made the biggest sales volume, followed by India and Pakistan.  In 2007, these three countries shared for 60.3% of total sales while in 2011 the share was increased to 62.8%.  The BusinesStat has forecasted that during 2012-2016, sales of cotton yarn will increase 2.1% annually and the volume will reach 15.6 million tons in 2016.


For spinning technology, Rieter introduces its new E80 comber featuring fully automated lap change and ROBOlap piecing system.  Compared with its predecessor model, the E80 has a 45% greater combing area and up to 20% imperfections (IPI values) can be reduced.  In addition, Rieter also introduces the new G32 ring spinning machine and the R60 rotor spinning machine.  Both machines provide high productivity with low energy consumption.  OerlikonSchlafhorst recommends its new Autocoro 8 rotor spinning machine with a rotor speed of 200,000 rpm, while OerlikonBarmag recommends the FDY take-up winding machine WINGS.  Machinery from the Oerlikon Textile group also show high productivity as well as energy saving.


Recently a new water jet texturing method has been introduced for texturing of polyester filament yarn.  This new texturing method was originally researched at the University of Manchester, UK.  The texturing trial conditions for polyester filament are as follows: speeds 800-2,000 m/min, water pressure 50-120 bar, draw ratio 1.63, and steam temperature 230°C and 260°C according to the speed used.  With this texturing method, yarns with better bulk and dyeing properties are obtained.  However, morphology study of textured yarns using SEM (scanning electron microscope) technique shows some cracks (due to twist) and damages (due to yarn friction) on fiber surface which can lead to lowering the yarn tenacity.
