结合了含氟聚合物短纤维的纱线
摘要：
由短纤维制成的纱线，所述短纤维包括平均卡尺直径为至少15微米的多根含氟聚合物短纤维和多根非含氟聚合物短纤维，其中，纱线中含氟聚合物短纤维与非含氟聚合物短纤维的平均卡尺直径的比率为1.2或更大。还教导了由短纤维制成的纱线，其包含具有矩形横截面且平均卡尺直径至多500微米的多根含氟聚合物短纤维和平均卡尺直径至多40微米的多根非含氟聚合物短纤维。
摘要（英）：

Yarns made from staple fibers comprising a plurality of fluoropolymer staple fibers with an average caliper diameter of at least 15 micron and a plurality of non-fluoropolymer staple fibers, wherein the ratio of the average caliper diameter of the fluoropolymer staple fibers to the non-fluoropolymer staple fibers in the yarn is 1.2 or greater. Also taught are yarns made from staple fibers with a plurality of fluoropolymer staple fibers having a rectangular cross-section and with an average caliper diameter up to 500 micron, and a plurality of non-fluoropolymer staple fibers with an average caliper diameter up to 40 micron.
