include for example varying amounts of one or more of lycra coolmax thermax and thermastat in a preferred embodiment the fabric is treated so that the fabric has antimicrobial properties by using circular knit performance fabric the fabric is able to provide elasticity in all four directions this property allows for the sheet to fit extraordinary mattress cushion and bedding shapes as well as providing better fits for traditional rectangular sheets by using performance fabrics the sheet has elastic properties that allow stretching in the directions shown as 30 in addition by using circular knit performance fabric the resulting bedding retains an exceptionally fine tactile quality critical for providing maximum levels of enhanced comfort an alternative to circular knitting is non circular knitting u2014 for example warp knitting this method can achieve widths greater than circular knitting industrial warp knit machines for example can produce tricote warp knit fabrics up to 130 140 inches in width circular knitting however is less expensive as it requires less set up time circular knitting also provides greater multidirectional stretch in order to provide a sheet that exceeds the maximum dimensions of fabric that can be produced by available circular knitting machines flat lock stitching 12 is used to join a plurality of portions resulting in a sheet that is 91 inches wide as shown in an exemplary embodiment piping 11 can be included in close proximity to the stitching the stitching can be the same color as the fabric.
