lightbulbQuick Answer
Engineering high-strain dynamic performance activewear—such as elite compression leggings, sprinting tights, gymnastics wear, and high-impact sports bras—demands synthetic fibers that combine high elastic recovery, low moisture regain, high tensile modulus, and bio-based sustainability. Textile materials engineers routinely compare GRS-Certified Recycled Nylon 6,6 (rN6,6) against 70% Bio-Based Polyamide 4,10 (PA 4,10) synthesized from castor bean plant oil derivatives.
For additional material science comparisons of advanced bio-polyamides, consult our technical guides on Recycled Nylon 6,6 vs Bio-Based Polyamide 6,10, Recycled Nylon 6,6 vs Bio-Based Polyamide 12, and Recycled Nylon 6,6 vs Bio-Based Polyamide 6,12.
1. Molecular Structure & Elastic Recovery Mechanics
The chemical structure of Polyamide 4,10 grants distinct physical advantages over conventional post-industrial or post-consumer Recycled Nylon 6,6:
- Recycled Nylon 6,6 (rN6,6): Formed from hexamethylenediamine and adipic acid, Nylon 6,6 exhibits a dense hydrogen-bonded crystal lattice yielding high tensile tenacity (8.2 g/d) and burst resistance. However, its 4.0% moisture regain rate causes fiber swelling under heavy perspiration, leading to temporary fabric elongation and loss of compression pressure.
- Bio-Based Polyamide 4,10 (PA 4,10): Synthesized by reacting tetramethyldiamine with plant-derived sebacic acid, PA 4,10 achieves a 70% bio-based carbon ratio. The unique 4-carbon / 10-carbon repeating monomer units produce high crystalline symmetry with low moisture regain (1.4%). In high-strain dynamic athletic apparel, PA 4,10 resists sweat-induced sagging and maintains uniform muscle compression throughout intense workouts.

The table below summarizes mechanical testing parameters for 220 GSM 4-Way Stretch warp knits (80% Polyamide + 20% Elastane):
| Material Property / Benchmark | Recycled Nylon 6,6 (80%) + Elastane (20%) | Bio-Based Polyamide 4,10 (80%) + Elastane (20%) |
|---|---|---|
| Bio-Based Renewable Carbon Ratio | 0% (100% GRS Post-Industrial Recycled) | 70% Bio-Based (Castor seed derived) |
| Moisture Regain Rate (ISO 62) | 4.0% (Risk of compression loss in wet state) | 1.4% (Ultra-low regain & quick dry performance) |
| Density / Specific Gravity | 1.14 g/cm³ | 1.07 g/cm³ (6.1% Lighter garment weight) |
| Elastic Memory Retention (10,000 Cycles @ 100% Extension) | 94.5% Retention (Slight hysteresis stretch residual) | 99.2% Retention (Superior shape recovery) |
| Melting Point (DSC ISO 11357) | 265°C | 250°C (Excellent thermal stability during heat setting) |
| Primary Activewear Application | Heavy-contact athletic shorts & high-abrasion gear | Elite compression tights, sprinting skinsuits, sports bras |
3. Selection Strategy for Dynamic Sportswear
Choosing between Recycled Nylon 6,6 and Bio-Based Polyamide 4,10 depends on garment function and environmental exposure:
- Choose Recycled Nylon 6,6 for: Outerwear subjected to direct physical abrasion (e.g., rugger shorts, climbing pants) where maximum tenacity (8.2 g/d) is required.
- Choose Bio-Based Polyamide 4,10 for: Elite compression tights, sprinting suits, and eco-conscious athletic apparel where 70% bio-content, 1.4% ultra-low moisture regain, 6.1% lighter garment weight, and 99.2% elastic memory yield unmatched performance.

Frequently Asked Questions
What is the bio-based content percentage of Bio-Based Polyamide 4,10?
Polyamide 4,10 features approximately 70% renewable bio-based carbon derived from castor bean oil sebacic acid monomers.
Why is 1.4% ultra-low moisture regain beneficial for compression tights?
Ultra-low moisture regain prevents sweat absorption inside the fiber core, ensuring compression tights remain tight, lightweight, and dry during intense athletic exertion.
How does the weight of PA 4,10 compare to standard Nylon 6,6?
With a density of 1.07 g/cm³ compared to 1.14 g/cm³ for Nylon 6,6, PA 4,10 produces activewear garments that are approximately 6.1% lighter.
Is Bio-PA 4,10 suitable for high-temperature sublimation heat transfer printing?
Yes, with a melting temperature of 250°C, PA 4,10 handles standard dye-sublimation transfer printing temperatures (190°C–205°C) without fiber degradation.
