Abstract (en)

[origin: WO2006060826A1] The present invention relates to a method for reducing the amount of die buildup associated with the production of polyolefin based elastic fiber and for improving the unwind or release characteristics of such fiber. In particular the method involves the use of polydimethylsiloxane (PDMSO) in the polyolefin resin.
