iHeir-666 water-based water repellent agent provides excellent waterproof, oil-proof, and stain-proof (three-proof) finishing for fabrics

iHeir-666 Water-Based Water Repellent Agent

Product Overview

iHeir-666 is an environmentally friendly fluoropolymer emulsion specifically designed to provide excellent water, oil, and stain repellency (three-proof finishing) for fabrics such as polyester, nylon, and polyester/cotton blends. This product is a non-flammable water-based emulsion, free of APEO, with extremely low PFOS content (PFOA < 1ppm), meeting modern environmental requirements. Treated fabrics maintain their natural hand feel, appearance, and breathability while gaining durable and reliable protection.

Product Features

• Environmentally friendly & safe: Free of APEO, extremely low PFOS and PFOA content (PFOA < 1ppm), environmentally friendly.

• Economical & efficient: Low usage on synthetic fabrics, high cost-performance ratio.

• Wide process adaptability: Insensitive to bath pH, good stability, can be used with various textile auxiliaries.

• Flexible application methods: Suitable for spraying, foaming, knife coating, padding, exhaustion, and other processes.

• Maintains fabric characteristics: Does not alter the hand feel, appearance, or breathability of the fabric after treatment.

Physical Properties

Application Methods

1. Fabric Preparation

• Residual wetting agents, dyeing auxiliaries, sizes, softeners, etc., must be removed from the pre-treated fabric.

• Fabric lint shedding rate ≤ 1.5%, alkali content ≤ 0.05%, fabric should be weakly acidic.

2. Bath Preparation

• Add the required amount of iHeir-666 to the mixing tank, then slowly add tap water. Finally, stir at low speed for 5–10 minutes until uniform, avoiding excessive foam.

• When using together with crosslinkers, penetrants, etc., pre-test compatibility and dilute each component separately before mixing.

3. Recommended Dosage (g/L)

4. Padding Process

• Padding method: one dip one nip (laboratory recommendation: three dips one nip)

• Pre-drying: 110–130°C

• Curing: 170°C (fabric surface temperature), 60 seconds (tenter frame)

5. Precautions

• Perform compatibility tests before using with other auxiliaries.

• Stir slowly during preparation to avoid excessive foam.

• Fluorine-based water repellents may cause a darkening effect; pre-check color change.

• Curing must be thorough, otherwise repellency performance will be affected.

• Use the treatment bath within 12 hours.

• Avoid using roller drying to prevent resin residue adhesion.

Performance Data Examples

Polyester (320T Spring Filling)

Nylon (228T Taslon)

Water repellency reaches 100 points at a dosage of 5 g/L (pH≈6 or 4).

Polyester/Cotton Blend

At a dosage of 30 g/L, water repellency is 100 points, oil repellency is grade 6.5.
