Cotton and flax

Cotton fibre consists mainly of cellulose and some other components, as shown below:

Cotton production may use chemicals such as pesticides, herbicides and defoliants and these may remain as a residue on raw cotton fibres that reach the textile mill. However, this is of little concern for the textile industry (the problem is rather with the growers). In fact, tests of cotton samples from around the world, performed from 1991 to 1993, reported levels of pesticides below the threshold values for foodstuffs [11, US EPA, 1995].

Other sources ([207, UK, 2001]) report that a few years ago, bails of cotton were found to be contaminated with pentachlorophenol from its use not only as a defoliant, but also as a fungicide applied on the bales of cotton during transport.
