filaments experimentation has found that as shown in fig3 conventional fibers of twisted filaments have much less area on the perimeter for charged metallic nanoparticles or ionic metal nanoparticles to occupy however it was found that the very small gaps descending into microfiber yarn forming the microfiber material 16 fig1 which render it soft to the touch also provide an exceptionably large surface area compared to yarns forming other fabric material such as cotton as shown in fig3 it is in this narrow but plentiful surface area between filaments or descending into the filaments forming the microfiber yarns formed to the microfiber material 16 fig1 where metal nanoparticles 20 are imparted and stay frictionally engaged until dislodged or until they encounter a pathogen further in these narrow passages depending into the yarn forming the microfiber material pathogens are drawn and can mix and be dispatched in an encounter with the nanoparticles such as in fig4 as can be discerned the surface area and descending areas of each of 30 filaments forming a 15 denier yarn of microfiber such as in fig4 significantly exceeds the surface area of each of 3 to 4 filaments twisted to form nylon stocking yarn or cotton yarn such as in fig3 further the spaces between the twisted filaments of the microfiber yarn form gaps descending therein which are particularly well sized and suited to frictionally engage metal nano particles therein as such the employment of.
