Hydrophilic Fabric Modifiers

Properly cured Hydrophilic Fabric Modifiers form a crosslinked film on the fiber surface. Durability depends on curing conditions, fiber type, and laundry temperature. Typical results show maintained absorbency after 20 to 30 home launderings at 40 degrees Celsius. For higher wash durability, a binder or crosslinker can be added according to technical recommendations. Pre-testing with the actual fabric and laundry conditions is advised.

Yes. Hydrophilic Fabric Modifiers are compatible with many fluorine-free repellent systems. However, the order of application and pH adjustment must be controlled. In some cases, a two-bath process is preferred to avoid interference with the repellent finish. A compatibility test is recommended before bulk production. The technical service team can advise on specific combinations.

The finishing bath should be maintained between pH 5.5 and 6.5 for optimal stability and performance. If the bath pH exceeds 7.0, the hydrophilic effect may decrease. Acetic acid or a buffering agent can be used for adjustment. Measure pH after all components are added and before application.

Hydrophilic Fabric Modifiers are formulated to have minimal impact on shade and color fastness when applied according to recommended conditions. However, deeply dyed shades and certain reactive dyes should be tested for migration and rub fastness. The product line includes options compatible with dry and wet rubbing fastness enhancers offered by Jiangyin Huanan. Delta E values typically remain below 0.5 for most shades.

Yes. The weakly cationic and non-ionic grades are designed for exhaust application in package dyeing, winch, and jet machines. For package dyeing, a dilution step before addition is advised to prevent local over-concentration. Typical exhaust dosage is 1 to 4 percent owf at 40 to 60 degrees Celsius for 20 to 30 minutes. Ensure good circulation and rinse if required by the subsequent process.

Non-ionic grades offer broader compatibility with other auxiliaries and are less sensitive to pH changes. Weakly cationic grades provide stronger affinity to synthetic fibers and may perform better in exhaust applications on polyester and polyamide. The choice depends on the fiber blend, the presence of anionic dyes or auxiliaries, and the application method. Technical data sheets provide specific guidance for each grade.

Yes, they are compatible with many silicone softeners, including amino-functional and hydrophilic silicone systems. However, the order of addition and pH must be controlled. In some cases, a two-bath process is preferred. Pre-testing is recommended to confirm stability and performance. Jiangyin Huanan offers a range of silicone softeners that can be paired with these modifiers.
