Strategies for Removing Chemical Finishes from Post-Consumer Outdoor Fabrics

Contaminants Removal From Acrylic Fabrics

In particular, the following finishes Proposed mechanism of bond cleavage by acid hydrolysis
were removed:

Proposed mechanism of bond cleav-
age by photolytic degradation of fluo-
Proposed mechanism of bond cleavage by alkaline hydrolysis
rocarbon resin
Preliminary laboratory experiments
have shown that the combination of
the three chemical processes, support-
ed by the photoirradiation of fabrics,
is responsible for over 90%* removal
of the applied finishing “A”.

Proposed mechanism of bond cleavage by photolytic deg-
radation of fluorocarbon resin

Waterproof coating
Preliminary laboratory experiments have shown
that the combination of the three chemical pro-
cesses, supported by the photoirradiation of
fabrics, is responsible for over 90%* removal of
the applied finishing “B”.
