NylonIn 1938, DuPont began commercial production of nylon toothbrush bristles for the so-called "Miracle Tuft Toothbrush." Before 1938, the world relied on toothbrush bristles of neck hairs from wild swine from Siberia, Poland and China. When DuPont created nylon it was the toothbrush which was the first item to benefit from the use of nylon. There were many advantages in this new brush including a dramatic reduction in production costs and the ability to control bristle texture. Wheareas, whereas bristles made with wild boar hairs fell out, wouldn't dry very well or became full of bacteria. At first, the consumers were not entirely satisfied because the early nylon bristles were very stiff and hurt the gums. By 1950, Du Pont produced softer nylon bristles. |
