摘要： This invention relates to a yarn, and a process for making the yarn, the yarn comprising a plurality of spun filaments having a distinct, continuous, uniform-density sheath of a first polymer surrounding a distinct, continuous core of a second polymer; the first polymer further having a thermal decomposition temperature at least 50 degrees Celsius lower than the thermal decomposition temperature of the second polymer.
