Read this: The era of manufactured fibers began with the development of rayon in France in the 1890s. Rayon is derived from a natural cellulose and cannot be considered synthetic, but requires extensive processing in a manufacturing process, and led the less expensive replacement of more naturally derived materials. A succession of new synthetic fibers were introduced by the chemicals industry in the following decades. Acetate in fiber form was developed in 1924. Nylon, the first fiber synthesized entirely from petrochemicals, was introduced as a sewing thread by DuPont in 1936, followed by DuPont's acrylic in 1944. Some garments were created from fabrics based on these fibers, such as women's hosiery from nylon, but it was not until the introduction of polyester into the fiber marketplace in the early 1950s that the market for cotton came under threat. The rapid uptake of polyester garments in the 1960s caused economic hardship in cotton-exporting economies, especially in Central American countries, such as Nicaragua, where cotton production had boomed tenfold between 1950 and 1965 with the advent of cheap chemical pesticides. Cotton production recovered in the 1970s, but crashed to pre-1960 levels in the early 1990s.

Läs detta: Den tid då tillverkade fibrer började med utvecklingen av rayon i Frankrike på 1890-talet. Rayon härleds från en naturlig cellulosa och kan inte betraktas som syntetiskt, utan kräver omfattande bearbetning i en tillverkningsprocess, och ledde till det billigare utbytet av mer naturligt framställda material. En rad nya syntetiska fibrer introducerades av den kemiska industrin under de följande årtiondena. Acetat i fiberform utvecklades 1924. Nylon, den första fiber som syntetiserats helt från petrokemiska ämnen, introducerades som sytråd av DuPont 1936, följt av DuPonts akryl 1944. En del plagg skapades av tyger baserade på dessa fibrer, till exempel damstrumpor från nylon, men det var inte förrän polyester infördes på fibermarknaden i början av 1950-talet som marknaden för bomull kom under hot. Det snabba utnyttjandet av polyesterplagg på 1960-talet orsakade ekonomiska svårigheter i bomullsexporterande ekonomier, särskilt i centralamerikanska länder, som Nicaragua, där bomullsproduktionen hade blomstrat tiofaldigt mellan 1950 och 1965 i och med tillkomsten av billiga kemiska bekämpningsmedel. Bomullstillverkningen återhämtade sig under 1970-talet, men kraschade till nivåer före 1960-talets början. Vad tillverkades helt av DuPont? Vad är svaret?
