Polypropylene Fiber: Uses, Types, and How to Source from China
As global demand for durable and cost-effective synthetic fibers grows, polypropylene fiber has emerged as a versatile solution across multiple industries. This lightweight yet strong material offers unique advantages for textile, construction, and industrial applications.
How to Find Reliable Polypropylene Fiber from China in 2025
China remains the world's leading producer of polypropylene fiber, offering competitive pricing and advanced manufacturing capabilities. When sourcing:
- Verify supplier certifications (ISO, SGS)
- Request product samples for quality testing
- Check production capacity and lead times
- Review export experience to your target market
Top manufacturing hubs include Zhejiang, Guangdong, and Jiangsu provinces, where most specialized factories maintain strict quality control standards.
What Buyers Should Know Before Buying Polypropylene Fiber from China
Key considerations when importing:
- MOQ requirements (typically 1-5 tons for standard products)
- Shipping methods and associated costs
- Customs clearance documentation
- Payment terms (30% deposit is common)
Case Study: A U.S. textile manufacturer reduced material costs by 22% after switching to a verified Chinese supplier, maintaining identical quality specifications.
Types of Polypropylene Fiber
Major variants include:
- Staple fiber: 3-120mm length for nonwovens and fillings
- Continuous filament: For high-strength textiles
- Microfiber: Ultra-fine denier for specialized filtration
- Hollow fiber: Thermal insulation applications
Functions and features of Polypropylene Fiber
Key advantages:
- Moisture resistance (0% water absorption)
- Chemical inertness (pH 2-12 tolerance)
- Lightweight (0.91g/cm³ density)
- High tensile strength (3-8g/denier)
Scenarios of Polypropylene Fiber
Common applications:
- Geotextiles (35% of global usage)
- Medical nonwovens (growing 7% annually)
- Automotive interiors (replacing traditional materials)
- PPE manufacturing (masks, protective suits)
How to Choose Polypropylene Fiber
Selection criteria:
- Determine required denier (1-15 typical range)
- Verify UV stability for outdoor use
- Check thermal bonding capability
- Assess colorfastness if dyed
Polypropylene Fiber Q & A
Q: What's the price range per ton?
A: $1,200-$2,500 depending on specifications and order volume.
Q: How does it compare to polyester fiber?
A: More chemical resistant but less heat stable (melts at 160°C vs 250°C).
Q: Can it be recycled?
A: Yes, with proper collection systems - increasingly important for eco-conscious buyers.
Q: Minimum order quantities?
A: Most Chinese suppliers require 1 ton for standard products.
Q: Lead time for production?
A: Typically 15-30 days after deposit confirmation.
