CHALLENGER - AIR ENTANGLED POLYESTER

Air Entangled Threads are made from continuous filaments of polyester that are entangled as they pass through a high pressure air jet. This yarn is then twisted, dyed and wound on cones with lubricant. Air entangled threads are used in everything from quilting mattresses to sewing heavy denim jeans.
