more specific aspects of the present invention will be appreciated in view of the following specific examples . a level loop nylon carpet made from dupont nylon fibers was obtained in a semi - finished form , that is , the fibers were locked in a primary backing but no additional latex or other backing materials had been applied to the underside of the carpet . a rubber latex available under the trade name vulcanol 5023 was obtained . to 65 parts of the rubber latex there was added 15 parts of advastat 50 , 15 parts of dowanol eph and 5 parts of a surfactant , aerosol o . t . 75 . the underside of a 28 inch × 30 inch sample of the nylon carpet weighing 491 . 2 grams was coated with 594 . 5 grams of the foregoing composition . the sample was dried in an oven at 275 ° f for 25 minutes . the total dried weight of the carpet plus the backing layer was 840 . 5 grams . the weight of the antistatic agent was 10 . 6 % of the total weight of the finished product . the volume resistivity of the treated carpet was measured at 2 . 4 × 10 9 as compared with 2 . 8 × 10 11 for the untreated carpet . the carpet was then subjected to a &# 34 ; stroll test &# 34 ; ( aatcc test method 134 - 1969 ) to determine the static level in volts for the untreated and treated samples . the threshold volume of 3 , 000 volts was used as the guideline to determine whether the carpet sample was antistatic , since , as described above , 3 , 000 volts is the point at which humans are sensitive to shock from the discharge of accumulated static electricity . the untreated sample showed a voltage of 13 , 200 whereas the voltage on the treated sample was 1600 volts , far below the threshold level . the treated carpet was shampooed under commercial conditions and re - tested . after drying to 20 % relative humidity , the volume resistivity was found to be 100 volts . the treated carpet was then placed in a hallway and subjected to normal use . the number of persons walking across the carpet was counted . after 16 , 000 cycles ( 1 cycle equals one person walking across the carpet ) the carpet was re - tested and showed a static level of 5 , 200 volts , above the threshold level . upon shampooing the carpet and re - testing it was found that the static level had returned to 1 , 200 volts , well within acceptable limits . exposure to 16 , 000 cycles is roughly equivalent to two years of normal residential use . the exact explanation for this result is not fully understood . apparently the buildup of soil during normal usage impairs the effectiveness of the antistatic material in the fibers . upon removal of the soil by shampooing and perhaps the removal of some of the antistatic agent in the same process , the antistatic characteristics are fully restored . the ability of the carpet to recover its high antistatic level is believed to be attributable to continued migration of material from the layer applied to the backing up through the fibers and to the accelerated migration attributable to the use of a carrier in the composition . the process as generally described in example 1 was repeated except for the changes indicated in table 1 . in those instances in which a carrier is employed , the presence of the carrier in the composition resulted in improvement in the antistatic properties of the carpet . table 1__________________________________________________________________________ex . no . carpet fiber antistat coating base carrier__________________________________________________________________________2 nylon ( bigelow ) ethoquad c / 12 letol l - 9960 none3 &# 34 ;
