process to form either a single layer or a multiple layer fabric is continuous that is the process steps are uninterrupted from extrusion of the filaments to form the first layer until the bonded web is wound into a roll the spunmelt nonwoven fabric of the present invention has a preferred basis weight range of 0 50 2 50 osy with a most preferred basis weight range of 1 0 2 0 osy incorporated into the spunmelt polymeric melt of the nonwoven fabric is a reversible thermochromic pigment in the present invention the nonwoven fabric is lavender at room temperature however the color of the fabric can be any one of an array of colors based on the thermochromic pigment used and is not meant to be a limiting factor of the present invention the reversible thermochromic nonwoven fabric has a preferred temperature indicating range of 40 u00b0 c 60 u00b0 c with the most preferred temperature indicating range of 45 u00b0 c 55 u00b0 c the nonwoven fabric of the present invention changes from lavender to white when exposed to temperatures within the fabrics temperature indicating range once the temperature has risen above or below the temperature indicating range of the thermochromic nonwoven fabric the fabric reverts back to the lavender color the reversible thermochromic pigment utilized in the present invention contains particles preferably 3 5 microns in size with a most preferred particle size of 3 microns the chemistry of the reversible thermochromic pigment is a conventional construct consisting of.
