LIQUID FIBER PRODUCT FEATURES
Multiple color production
• Depending on the manufacturing set-up, several
injection points can be added to enable multiple
color production at the same time on a single
extruder
Batch size flexibility
• Fiber producers can manufacture anything from
a few kilograms to hundreds of tons using the
same simple process
Rapid color changes
• No extruder contamination and easy color-on,
color-off operation increases color change speed
Waste reduction
• Rapid color changes, precise metering and
the ability to adjust color in-line reduces waste
during color changeovers
Continuous metering & long spin pack life
• High pigment and dye concentrations mean
fewer pack changes are required
• Where color is running low for larger volume
runs, low level metering sensors alert operators
and packs can be changed without disrupting
production
In-line IV adjustment
• Specialist additives are available to adjust
Intrinsic Viscosity (IV) in-line for rPET applications
• These additives are available as single products,
or can be combined with color
to create a multi-functional formulation
Color design service
• ColorMatrix offers a dedicated color design
service to help shorten product development
cycles and enhance market agility
Liquid color processing
• Formulations are stable at temperatures up
to 60°C and retain good flow properties at
temperatures as low as 10°C
• These formulations can help lower yarn friction
and abrasion, and there is no fuming
or evaporation during production
