Knit candle wicks provide a stable, higher yield yet similar burn rate or flame height as compared to lower yield braided candle wicks by providing improved capillary flow as well as an increase in the functional surface area. In addition, candle burning safety is improved as the wicks of this invention provide a self-trimming wick that creates a more stable flame height and uniform wax pool diameter as the candle burns. In preferred forms, the knit wicks of this invention are a warp knit construction in which the interlocking loops run lengthwise in the direction of the wick material. In addition, the various warp knit constructions can comprise both interlocking loop or warp ends as well as weft or laid-in yarns. The wicks of the present invention thus advantageously provide for a stable wick construction that meets the performance and process requirements desired of wicks generally, including flame height, stable wax pool, uniform diameter wax pool, is self-trimming and/or self-supporting, while at the same time providing a higher yield wick with improved capillary flow and enhanced safety features when compared to conventional candle wick constructions.
