Original Levi's did not contain rivets. A tailor by the name of Jacob Davis invented riveted pants at the request of a miner who complained that regular pants were not rugged enough to hold his mining tools. Davis subsequently granted Strauss the use of his rivet idea, which was patented on May 20, 1873. Few other changes were made over the next century. Zippers replaced button flies in 1920 (although later button flies had a resurgence of popularity) and in 1937 the rivets on the back pockets were moved inside in response to complaints from school boards that the jeans students wore were damaging chairs and from cowboys that their jeans were damaging their saddles. In the 1960s, they were removed entirely from the back pockets.
Selvage denim (also called selvedge denim) is a type of denim which forms a clean natural edge that does not unravel. It is commonly presented in the unwashed or raw state. Typically, the selvage edges will be located along the outseam of the pants, making it visible when cuffs are worn. Although selvage denim is not completely synonymous with unwashed denim, the presence of selvage typically implies that the denim used is a higher quality
Blue jeans started becoming popular among young people in the 1950s. In the year 1957, 150 million pairs were sold worldwide. This growing trend continued until 1981 and jeans manufacturers were virtually guaranteed annual sales increases. In the United States, 200 million pairs of jeans were sold in 1967, 500 million in 1977, with a peak of 520 million in 1981. When jeans first caught on, apologists reasoned that their low price determined their huge success. During the 1970s, however, the price of blue jeans doubled, yet demand always exceeded supply. Sometimes manufacturers met the demand by providing stores with irregulars; that is, slightly defective merchandise that would not normally be sold.
Shuttle looms weave a more narrow piece of fabric, and thus a longer piece of fabric is required to make a pair of jeans (approximately 3 yards). To maximize yield, traditional jean makers use the fabric all the way to the selvage edge. When the cuff is turned up the two selvage edges, where the denim is sewn together, can be seen. The selvage edge is usually stiched with colored thread: green, white, brown, yellow, and red (red is the most common). Fabric mills used these colors to differentiate between fabrics. Most selvage jeans today are dyed with synthetic indigo, but natural is available in smaller niche denim labels. Loop dying machines feed a rope of cotton yarn through vats of indigo dye and then back out. The dye is allowed to oxidize before the next dip. Multiple dips create a deep dark indigo blue.
Although the demand for jeans actually decreased in the 1980s, a brief surge occurred with the introduction of designer jeans to the market. Despite the apparent success of designer jeans, however, they did not capture the majority of the market; jeans have not returned to the height of popularity they achieved in the seventies. Manufacturers must therefore constantly seek ways to keep the demand for blue jeans high. Believing that the decrease in demand reflects the changing needs of an aging population, jeans manufacturers have begun to cater to the mature customer by providing roomier, more comfortable jeans. Sally Fox, an entomologist, has developed cottons that naturally come in beige, brown, and green. The Levi Strauss Company now markets multicolored jeans as well. The company hopes to ride the popular wave of environmentalism, even advertising their new product on recycled denim.
In response to increased demand for jeans in the 1950's, American denim manufacturers replaced the old shuttle style looms with modern projectile looms. The new looms produced fabric faster and wider (60-inches or wider), yet lighter and less durable. Synthetic dyeing techniques along with post-dye treatments were introduced to control shrink and twist.
Although blue jeans have remained basically the same since they were first designed, they have always been versatile enough to meet market demands. Since futuristic, yet familiar, "Levi's" appeared in the movie Star Trek V, it can be surmised that manufacturers as well as the public, expect blue jeans to be around indefinitely.
