  • exemplary gloves can be produced and analyzed.
  • the exemplary gloves can comprise the materials noted in the instant example.
  • Analysis of the exemplary gloves can include an evaluation of tackiness and elasticity. For instance, tackiness can be evaluated on a scale from 1-5, with “5” representing the best degree of tackiness (i.e., not tacky). Further, elasticity can be evaluated on a scale from 1-5, with “5” representing the best degree of elasticity (i.e., very elastic).
