the origin of US dollar note

US dollar note is made of cotton fiber and hemp. Long cotton fiber makes paper not easy to break, good ink absorption, not easy to fade. Hemp fiber is strong and tenacious, which makes the paper stiff, rable and fluffy. It has certain resistance to water, oil and some chemical substances

There is no whitening agent in the paper, which is white and non reflective under the purple light. Since 1880, there have been red and blue fibers in American banknote paper, which were mixed with pulp in papermaking. Therefore, some fibers are sandwiched in the paper, some float on the surface, and can be picked out with the tip of a needle

Before 1928, red and blue filaments were distributed in the middle of banknotes, a narrow strip from top to bottom. In 1928 and later editions, the full edition of fiber diffuse cloth. Since 1990, a safety line made of polyester polymer material called "Myra" has been added to the dollar paper (on the left side of the portrait). There are dollar symbols and denomination numbers on the safety line, which can be seen clearly under the light. The ink on the front of the dollar is black, slightly dark, slightly gray, and the back is green

after 1934, magnetic material was added to the ink in various editions, and the real US dollar bill with magnetism was specially made with special ink such as fluorescent ink and magnetic ink, so the green badge and green number on the right side of the front of the US dollar bill can leave "green mark" on the paper after being wiped on the white paper

some U.S. dollars issued after 1996 will show black and green with different light angles. The main patterns of US dollar are engraving, gravure printing, library printing and serial number printing. After the 1990 edition, miniature characters were added around the portrait window below
