by yarns and isn 39 t necessarily related to any particular weave pattern rather the cover factor is related to how closely the yarns are woven or placed together in any given weave pattern for example in fig5 b it can be seen that the cover factor of all four different weaves without the inclusion of warp set two is the same value of 0 54 for fabric a and 0 50 for fabric b these calculated factors shown in fig5 a and 5b are based on the values calculated and listed in the chart for fabric weight ounces per square yard warp denier tex ends per inch warp cover kw fill denier fill tex fill per inch and fill cover kf anyone skilled in the art would know what these values represent as well as how to calculate them these values may be calculated as follows weave factor for plain weave 0 75 weave factor for 2 2 twill 2 2 basket and 4h satin 0 889 fig5 b shows the additional tightness values and fabric cover values that may be achieved by adding warp set two when looking at fig5 b the values listed under the column u201c tightness factor u201d or u201c fabric cover factor u201d for the rows that include the addition of warp set two it should.
