In spite of oil shortages in the 1970s, consumption of nylon textiles continued to grow by 7.5 per cent per annum between the 1960s and 1980s.[43] Overall production of synthetic fibers, however, dropped from 63% of the worlds textile production in 1965, to 45% of the world's textile production in early 1970s.[43] The appeal of "new" technologies wore off, and nylon fabric "was going out of style in the 1970s".[2] Also, consumers became concerned about environmental costs throughout the production cycle: obtaining the raw materials (oil), energy use during production, waste produced during creation of the fiber, and eventual waste disposal of materials that were not biodegradable.[43] Synthetic fibers have not dominated the market since the 1950s and 1960s.
