| Product Size | 2.5 x 3.0 (mm) | Dosage | 6% |
| Heat Resistance | 280 °C | Carrier Resin | PP / PE |
| Performance | Absorbing time of 45° angle: ≤ 5s | Absorbing Capacity | ≥ 3–8 times of original weight |
Application Field
PP Filament Yarn, PP Staple Fiber, PP BCF for Carpet, PP Nonwoven Fabric
Application Notes
It's designed for direct addition on the production of PP synthetic fiber or nonwoven fabric. Please use drying machinery or 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 shouldn't be too much at one time to avoid bonding and blockage in the feeding port and uneven mixing.
💧
Once the fabric is ready, a water spray device can be added to activate the hydrophilic group fastest and achieve the hydrophilic effect immediately. If no such device is available, place the nonwoven fabric in the air for 24–36 hours to allow it to cool to a certain moisture level, activating the hydrophilic effect before testing.
✅
It can be applied for PP or PE Casting Film, achieving excellent water-loving properties. Designed with characteristics of excellent water-loving property, permanent water-loving, and repetitive scrubbing performance.
Frequently Asked Questions (FAQ)
Q
What is the recommended dosage for the Water-loving Masterbatch (RPSH-04)?
The recommended dosage is 6.0%. This ratio ensures optimal hydrophilic performance when blended with PP or PE base materials.
Q
What carrier resins are compatible with this masterbatch?
The masterbatch is compatible with PP (Polypropylene) and PE (Polyethylene) carrier resins, making it suitable for a wide range of fiber and film applications.
Q
How long does the mixing process need to be before entering the feeding port?
The hydrophilic masterbatch and PP material must be mixed for more than 20 minutes before entering the feeding port to ensure uniform distribution and avoid blockage.
Q
How can I activate the hydrophilic effect after the fabric is produced?
You can use a water spray device to immediately activate the hydrophilic groups. If unavailable, simply place the nonwoven fabric in open air for 24–36 hours to allow natural moisture absorption and activate the hydrophilic effect before testing.
Q
What applications is this 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 permanent hydrophilic performance.
Q
Does the hydrophilic property remain after repeated washing or scrubbing?
Yes. The masterbatch is specifically engineered for permanent water-loving performance and repetitive scrubbing resistance, ensuring the hydrophilic effect is maintained even after multiple washes or mechanical abrasion.
