Whether in solid or liquid form, our fiber concentrates are developed for use in the more sustainable process of spin-dyeing, or dope-dyeing, which requires no water and less energy than other dyeing methods. Lower-concentration solutions can be developed to meet specific customer needs. Product range • Flame retardants to reduce flammability of fibers and fabrics especially in building and construction applications • Light stabilizers to protect fibers used outdoors or exposed to sunlight against UV light • Antimicrobials to protect hygienic fiber products from bacteria proliferation • Antistatics to reduce electrostatic charges • Antioxidants to reduce polymer oxidation during spinning and protect fabrics during service life • Optical brighteners to provide a brilliant white effect and blueish hue • Electrets to retain electrostatic charge on the polymer surface for a longer period of time in filtration applications • Hydrophobics to impart durable water repellency • Chain extenders for recycled polyester fibers • Others on request Product characteristics • Good spinnability • Fiber-specific QC and protocols • Lot-to-lot consistency • Carriers: PET, PBT, PA 6, PP, and others • Possibility to combine colors and additives into a combination concentrate for convenience • Product guidance from our fiber expert team • Focus on safe and sustainable formulations Applications • Continuous filaments (POY, FDY, HOY, BCF) • Long and short spinning staple fiber • Nonwoven processes (spunbond and meltblown) Cesa™ Fiber Additives MagIQ™ Liquid Fiber Colorants & Additives 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 • Avient 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 Avient’s liquid fiber colorant technology combines advanced liquid color formulations with state-of-the-art, high-pressure metering equipment to enable late-stage injection of liquid color for spun-dyed polymer melt.
