  • Patent number: 5858885
    Abstract: A smooth elastic stretch fabric which is plain woven with weft and/or warp yarns that include combination yarns which comprise a partially oriented synthetic crystalline polymer yarn combined with an elastomeric core wherein the smooth fabric (i.e., a non-crepe effect) is the result of a tight weave characterized by the reciprocal of the warp apparent fractional cover (i.e., 1/WaAFC) being in the range between about 1.13 and about 2.06. The fabric is stretched, heat set and finished under particular conditions to provide the resultant fabric with an elastic stretch of more than about 10% and dimensions about equal to the as-woven dimensions.
    Type: Grant

  • Patent number: 5837622
    Abstract: A smooth elastic stretch fabric which is plain, satin or sateen woven with weft and/or warp yarns that include combination yarns which comprise a partially oriented synthetic crystalline polymer yarn combined with an elastomeric core wherein the smooth fabric (i.e., a non-crepe effect) is the results of a tight weave characterized by the sum of the reciprocal of the weft apparent fractional cover and the reciprocal of the warp apparent fractional cover (i.e., 1/WeAFC+1/WaAFC) being in the range between about 2.34 and about 3.11. The fabric is stretched, heat set and finished under particular conditions to provide the resultant fabric with an elastic stretch of more than about 10% and dimensions about equal to the as-woven dimensions.
