Easy Preserves
Bio-degradable fibers as an effective way of reducing the impact
textiles have on the environment. Bio-degradation of fibers occurs when
their constituent polymers are depolymerised, usually by the action of
enzymes secreted by microorganisms. These enzymes act by hydrolyzing or
oxidizing the polymer, and can work on the ends of the chains or
randomly along their length. To do its work, the enzyme has to be able
to bond to the fiber and gain access to sites capable of being oxidized
or hydrolyzed.
The most bio-degradable fibers therefore tend to be
hydrophilic, and made up of short, flexible chains with low levels of
crystallization. They will often have chain backbones with oxygen or
nitrogen links and/or pendant groups containing oxygen or nitrogen
atoms. This description clearly fits most natural fibers and fibers made
of natural polymers.
