Quick Answer — High-Temperature Textile Jet Dyeing & Scouring Anti-Foaming

Defoamer M37 and shear-stable textile defoamers are dosed at 0.3 to 0.8 g/L in high-temperature jet dyeing machines to suppress extreme surfactant foam under venturi jet shear (130°C), preventing fabric rope knotting and pump cavitation without causing oil spot defects.

Textile jet dyeing defoaming is the application of shear-stable anti-foaming agents in enclosed pressurized dye vessels to suppress foam without oil separation.

Key Facts

  • •Withstands extreme venturi nozzle shear and temperatures up to 130°C.
  • •Eliminates fabric rope floating, knotting, and circulation pump cavitation.
  • •Guaranteed 100% free of oil spot staining or dye resist defects.
  • •Supplied in 45 kg and 180 kg drums across East Africa by KIKI'S.

Primary Use Cases

High-temperature polyester knit fabric jet dyeingContinuous cotton fabric scouring and peroxide bleachingCommercial denim garment enzyme fading laundry ranges

Technical Process

In high-speed textile wet processing, foam control must withstand extreme mechanical and thermal stresses:

The Jet Dyeing Machine Environment (High Shear & 130°C)

In modern overflow and high-temperature (HT) jet dyeing vessels, fabric rope travels at 200 to 400 m/min driven by high-velocity liquor nozzles. The combination of intense nozzle shear, scouring surfactants, and leveling chemicals creates massive foam volume. If left unmanaged, foam forces the fabric rope to float, causing tangled knots, uneven dye penetration, and pump cavitation that stalls circulation.

The Danger of Oil Spot Staining (Demulsification)

Standard low-grade defoamers break down under jet shear and high temperature (130°C for polyester dyeing). The oil carrier separates from the emulsion, depositing microscopic silicone or mineral oil droplets directly onto hot polyester fibers. These hydrophobic oil spots act as dye resists or pigment attractants, permanently ruining fabric lots. Defoamer M37 is formulated with modified polyether non-ionic emulsifiers that remain 100% shear-stable throughout heating and cooling cycles.

Dosing Protocol in Dyehouse Operations

Operators pre-disperse Defoamer M37 in warm water (1:5 dilution) and inject it into the dye machine expansion tank at 0.3 to 0.8 g/L alongside scouring and leveling chemicals before heating. The defoamer suppresses foam throughout the 45-minute dyeing cycle and washes out cleanly during warm overflow rinsing.

KIKI'S Industrial Chemicals supplies textile wet processing mills with shear-stable Defoamer M37 and dyehouse auxiliaries guaranteed spot-stain free.

Standard Application Process

  1. 1

    Dye Liquor Pre-Dispersion

    Dilute defoamer 1:5 in warm water; inject into jet expansion tank at 0.5 g/L with scouring and leveling auxiliaries.

  2. 2

    High-Velocity Venturi Circulation

    Circulate fabric rope at 300 m/min through jet nozzle; defoamer suppresses foam without nozzle cavitation.

  3. 3

    High-Temperature Dyeing Cycle

    Ramp temperature to 130°C (for polyester) or 95°C (for cotton); emulsion remains 100% shear-stable without oil separation.

  4. 4

    Overflow Rinsing & Inspection

    Wash down and rinse; defoamer emulsifies out cleanly, leaving fabric 100% free from oil spots or color streaks.

COMMERCIAL & TECHNICAL GUIDANCE

FAQs — High-Temperature Textile Jet Dyeing & Scouring Anti-Foaming

Technical and process guidance for high-temperature textile jet dyeing & scouring anti-foaming in Kenya and East Africa.

Oil spots occur when unstable defoamers break down under high jet shear and 130°C heat, releasing free oil droplets that deposit onto the fabric and resist or attract dye.
