Resumo(s)
Encapsulation imparts new properties and added value to
conventional fabrics. Most of the commercially
available microcapsules for textile applications are made of
melamine-formaldehyde, urea-formaldehyde or phenolformaldehyde
resins, which have significant negative health
and environmental effects. Recently, there has been a growing
interest in the replacement of these resins with safe and
environmentally benign materials.
The process of fixing the microcapsules onto textile substrates
is critical in ensuring their durability and effectiveness. The
commonly known industrial methods used for this involve the
use of two main groups of binders; polymeric resins, and
polyfunctional crosslinking agents. Polymeric resins are
reported to partially inhibit the release of fragrance from the
microcapsules. The chemical cross-linkers are subdivided into
formaldehyde based, e.g., formaldehyde and glutaraldehyde,
and non-formaldehyde based, such as polycarboxylic acids.
This work aimed at conferring fragrant and antibacterial
properties to cotton fabrics employing new methodologies
utilizing non-toxic and environmentally friendly materials.
