When choosing winter outerwear, bedding, or upholstered furniture, consumers often face a variety of synthetic fillers. The most well-known among them are syntepon and hollowfiber. Both materials are made from polyester fibers but differ significantly in fiber structure, applications, and longevity. Sumykamvol Factory, a leading manufacturer of non-woven materials, explains the differences.
What is Syntepon?
Classic syntepon in rolls is a non-woven fabric consisting of parallel layers of polyester fibers. It can be thermal-bonded (thermofixed under high temperature) or needle-punched. Thermofixed siliconized syntepon is softer, safer, and retains its shape much better during washing.
What is Hollowfiber?
Hollowfiber (often processed into siliconized fiber balls or synthetic down) consists of hollow, spiral-shaped polyester fibers that act like miniature springs. These fibers are arranged randomly or vertically. Due to this structure, the material bounces back to its original shape faster after compression.
Main Differences: Syntepon vs Hollowfiber
- Shape Retention: Hollowfiber has superior resilience, making it the perfect choice for filling pillows and cushions. Syntepon, while great for quilted garments, may settle slightly over time.
- Thermal Insulation: Since hollowfiber traps more air within its hollow spirals, it is slightly warmer than classic syntepon of the same weight.
- Washing and Care: A common question is: how do you wash a syntepon jacket without clumping? It is recommended to wash both materials at temperatures up to 30-40°C on a delicate cycle without intensive spinning. Siliconized fibers withstand machine washing far better without clumping.
Temperature Guidelines: Which Syntepon Density to Choose?
The density of non-woven fabrics is measured in grams per square meter (g/m²). This indicator determines the suitable temperature range for garments:
| Density (g/m²) | Temperature Range | Season |
|---|---|---|
| 80 – 100 g/m² | from +10°C to +5°C | Mid-season (Spring / Autumn) |
| 150 g/m² | from +5°C to -3°C | Late Autumn / Mild Winter |
| 200 g/m² | from -3°C to -10°C | Cold Winter |
| 300 g/m² | from -10°C to -20°C | Extreme Winter |
If you are looking for bulk supply for clothing manufacturing or upholstery, you can buy wholesale syntepon from the manufacturer directly. Explore our full range under the Non-Woven Materials section.
