    Application Field
    🧵 PP Filament Yarn, PP Staple Fiber, PP BCF for Carpet, PP Nonwoven Fabric
    Application Notes
    ⚠️ Designed for direct addition during production of PP synthetic fiber or nonwoven fabric. Please use drying machinery or a high-speed mixer to dry the masterbatch before application. The recommended add dosage is 6.0%.

    The hydrophilic masterbatch and PP material must be fully mixed before entering the feeding port (mixed time should be more than 20 min). At the same time, the hydrophilic masterbatch and PP material in the feeding funnel should not be added too much at one time, to avoid bonding and blockage in the feeding port and uneven mixing.

    Once the fabric is ready, the factory can add a water spray device which can activate the hydrophilic groups most quickly and achieve the hydrophilic effect immediately. If no such device is available, please place the nonwoven fabric in open air for 24–36 hours to allow the fabric to cool and absorb a certain level of moisture, activating the hydrophilic effect, and then proceed with testing.

    It can be applied for PP or PE Casting Film, achieving excellent water-loving properties. It is designed with characteristics of excellent water-loving property, permanent water-loving, and repetitive scrubbing.

    Frequently Asked Questions (FAQ)
    ❓ What is the recommended dosage for the Water-loving Masterbatch (RPSH-04)?
    ✅ The recommended dosage is 6.0%. This ratio ensures optimal hydrophilic performance without compromising the structural integrity of the final fiber or nonwoven fabric.
    ❓ What carrier resins are compatible with this masterbatch?
    ✅ This masterbatch is compatible with both PP (Polypropylene) and PE (Polyethylene) carrier resins, making it versatile for a range of fiber and film production processes.
    ❓ Does the hydrophilic effect of this masterbatch last permanently?
    ✅ Yes. RPSH-04 is engineered for permanent hydrophilicity. The water-loving property is retained even after repetitive washing or scrubbing, unlike surface-coated alternatives.
    ❓ How should the masterbatch be prepared before use?
    ✅ Before application, the masterbatch must be dried using drying machinery or a high-speed mixer. It should also be thoroughly mixed with PP material for at least 20 minutes before feeding into the production line.
    ❓ How can I activate the hydrophilic effect after fabric production?
    ✅ The fastest method is to use a water spray device immediately after production. If unavailable, place the nonwoven fabric in open air for 24–36 hours to allow natural moisture absorption, which will activate the hydrophilic groups.
    ❓ What applications is the Water-loving Masterbatch suitable for?
    ✅ It is suitable for PP Filament Yarn, PP Staple Fiber, PP BCF for Carpet, PP Nonwoven Fabric, and also applicable for PP or PE Casting Film, delivering excellent and durable water-loving performance across all these applications.
