Since
decades
Denimist
has
developed
know-‐how
in
denim
finishing
prior
to

garment
manufacturing
and
also
in
jeans
washing.
Our
customers
derive

benefit
from
this
experience.For
the
fabric
production
we
offer
finishing

chemicals
which
provide
the
demanded
fabric
properties
such
as
good

sewability,
stiffness,elasticity
and
handle.
The
other
field
of
our
activity
is
the

recommendation
of
laundring
Procedures
for
ready-‐made
clothing
such
as

trousers,
jackets
or
skirts,
shirts.

In
doing
so
we
have
learned
that
many
errors
may
occur
in
this
complicated

production
process.
The
laundry,
the
last
step
in
the
sequence
of

producers,
is

faced
to
difficulties
which
are
caused
by
previous
inaccuracies.
Therefore,
a

good
cooperation
among
the
steps
of
jeans
manufacturing
is
required
to
avoid

problems.
Fabric
producer,
garment
manufacturer
and
laundries
have
to
work

together
to
obtain
the
desired
end
result.
By
means
of
our
contacts
on
both

sides
of
the
production
process
we
are
able
to
make
our
contribution.

The
technical
stuff
of
Denimist

is
always
ready
to
help
our
customers
with

eventual
problems
and
to
modify
production
procedures
according
to
the

respective
requirements.
Through
our
numerous
contacts
which
we
have
got

with
denim
producers,
garment
manufacturers
and
laundries
during
the
years

we
support
the
team
work
among
all
sections
of
the
jeans
chain
and
make
our

know-‐how

available
to
all
of
the
parties
concerned

Deﬁnition

Coating
means
:

one-‐sided,
plane
application
of
textile
auxiliaries

Limits:

•  Textile
printing

•  Nip-‐padding

•  Spray-‐application

•  Lamination

DB
DENIM B O O K

•  Special
machines
necessary
for
coating

•  Modular
systems
are
most
common

•  Coating
station

•  Diﬀerent
knife
systems

•  We
coat:

•  Pastes
with
high
viscosity

•  Foams

•  Hot
melts

•  After
coating
we
need
a
stenter
or
dryer

•  Drying
and
condensation,
in
the
majority
of
cases
in
one
step

•  Crush-‐cylinder
and
calander
are
useful
additional
machinery

•  Printing
screens
can
be
used
to
apply
coating
pastes
and
foam

DB
DENIM B O O K

•  Air
knife

•  Coating
is
aﬀected
by:

•  Rigidity/Elasticity
(of
fabric)

•  Absorbency
of
the
fabric

•  Surface
condition
(roughness)

•  Viscosity
of
the
paste

•  Solid
content
of
the
paste

•  Knife
proﬁle

DB
DENIM B O O K

Roller
knife

•  Often
used
with
a
gap

(between
fabric
and
knife)

•  Add-‐on’s
from
50
g/m²
to
6,000
g/m²
(wet)
possible

•  Very
high
viscosities
can
be
handled

3,000
mPas

to
120,000
mPas
possible

•  Very
slick
fabrics
are
coatable

•  Commonly
used
for
application
of
stable
foams

DB
DENIM B O O K

Sharp
profiles

•  Low
penetration
in
the
fabric

•  Less
dry-‐add-‐on

•  Soft
handle

•  Strong
inter-‐dependence
with

the
surface
of
the
fabric

Round
profiles

•  Good
adhesion

•  Higher
stiffness

•  More
dry-‐add-‐on

Paste
coating

Pastes

•  Add
thickener
to
adjust
viscosity
from

6,000
mPas
to
20,000
mPas

•  Good
mixer
is
essential

•  Defoaming
not
only
for
preparation

but
also
for
running
on
the
fabric

Paste
coating

•  Closed
surface
after
coating

•  Compaction
of
the
fabric

•  Bad
permeability
to
air

•  Good
water-‐proof
performance
Glossy
surface

No
foam
or
particles

DB
DENIM B O O K

Coating
systems
(application)

Foam
coating

•  Air
for
dilution

•  Less
energy
costs
(less
water
to
vaporize)

•  Soft
handle

stitches
are
not
bonded
together

•  Breathability
with
normal
(
cheaper)
polymers

(application)

Instable
foam

Instable
foam
does
not
destruct
under
normal
conditions

Instable
means

•  Foam
destructs
in
heat

•  Foam
destructs
under
the
knife

•  Preserves
the
porosity
of
the
fabric

•  No
closed
ﬁlm

•  In
use
for:

•  Sealing
of
the
surface

•  Wash-‐out
eﬀects

•  Double-‐side
coloration

Instable
foam

Coating
systems
(application)

Stable
Foam

•  After

drying
it‘s
still
a
foam

•  Foam
stabilizers
necessary

•  Application
with
roller
knife
and
gap

•  Drying
at
max.
100
°C

•  Instantly
grout
after
drying

•  Don’t
roll
it
up
without
grouting!

•  Condensation,
embossing
and
calandering
in
second
step

•  Calandering
increases
the
adhesion
