The origin of paper money
Dollar notes are made of cotton fibers and hemp. Long cotton fiber makes paper not easy to break, good ink absorption and not easy to fade. Hemp fiber is tough, which makes the paper stiff for a long time and has certain resistance to water, oil and some chemicals. One-dollar paper is white without whitening agent and does not reflect light under purple light.
Since 1880, there have been red and blue fibers in the paper of dollar bills, which are mixed with pulp when making paper. So some fibers are sandwiched in the paper and some float on the surface, and the fibers can be picked out with the needle tip. Before 1928, red and blue fibers were distributed in the middle of banknotes, and they were long and narrow up and down.
1928 and later versions, full-page transmission of fiber silk. Starting from 1990, a safety thread made of polyester polymer called Myra was added to the dollar paper (as shown in the left). The security line has dollar symbols and denomination figures, which can be seen clearly through perspective. The ink on the front of the dollar is black, slightly dark and slightly gray, and the back is green.
