Mold in Textiles
In the present day world most of us are very conscious
about our hygiene and cleanliness. Now a days Textile
materials facing commonly mold problem during in
store, in packed garment or in shipment container are
not only related to microorganisms such as pathogenic
bacteria, odour generating bacteria and mould fungi,
but also good media for growth of microorganisms.
Mold, mildew, fungus, yeast, and bacteria
(microorganisms) are part of our surrounding
environment and also everyday lives.
Mold (or mould) is a term used to refer to fungi
that grow in the form of multicellular thread-like
structures called hyphae. European Textile Chemical

Mold in Textiles
Mildew is a form of fungus. Mildew is a surface
fungi that can easily be identified as a patch of gray
or even white fungus that is lying on the surface of a
moist area.
Fungus (fungi) is any member of the group of
eukaryotic organisms that includes microorganisms
such as yeasts and molds.
Yeasts are eukaryotic, single-celled microorganisms
classified as members of the fungus kingdom.
Bacteria (bacterium) are very small organisms. They
are prokaryotic microorganisms. Typically a few
micrometres in length, bacteria have a number of
shapes, ranging from spheres to rods and spirals.

Ideal Conditions For mold Growth
Warm temperature
Moisture (Humidity 70-80%, Spills)
Receptive surface (skin, fabric)
Sources of mold
In the air we breathe
In the soil
In our skin and bodies & Everywhere
Synthetic fibres are not totally immune to microorganisms,
for example; polyurethane fibres and coatings can be
damaged.
Wool is more likely to suffer bacterial attack than cotton, and
cotton is more likely than wool to be attacked by fungi.
Mold in Textiles

Reasons of mold in textile
Available starch in various fabrics.
Courser and compact fabric has a
greater tendency to form mold rather
than finer fabric.
Especially indigo dyed garment has a
tendency to grow Fungus.

Precaution for mold
Precaution
Keep fabric or garment in dry condition
Try to avoid moisture
Avoid humidal moisture
Control temperature
Check time to time humidity available in
various fabrics.
Mold and Fungi cause multiple problems to textiles including
discoloration, coloured stains, and fibre damage.
Bacteria are not as damaging to fibres, but can produce
some fibre damage,
unpleasant odours and a slick, slimy feel.
Corporation

Treatment to avoid mold formulation
Putting up ultraviolet light to kill the
fungus
Maintain the temperature of the
room or area
Control of the humidity of the place
or area
Put to the pack garment into a air
proof plastic bag avoid humidity
during packing area

Latest technology to control anti mold
or fungi
Anti Mold Finish (EUROSOFT AOAM )
It is a chemical finish have been used to
produce fibers, textiles or garments with
demonstrable anti mold properties. The
chemical is specially developed anti-
microbial organic hydrophilic softener to
prevent malodor from packed garments,
developed due to microbial growth. A
treatment with EUROSOFT AOAM protect
the substrate from developing mal-odor
while storage and transport. European Textile Chemical
Corporation

Applying technique of Anti Mold
Finishing
Treated at yarn stage
Treated at fabric stage
Treated after garment processing
Standard moisture content of
fabric supposed to be 8-10%. If
moisture content increases need
more dose of biological softener.
Corporation
