Regenerated Fiber vs. Synthetic Fiber: A Comprehensive Comparison of Environmental Impact, Durability, and Cost

The "Red and Black List" of Synthetic Fibers

Polyester (Polyester Fiber)
Innovation: Coolmax modification technology enhances breathability, increasing the drying speed of sport T-shirts by 50%.
Avoid: 100% polyester summer clothing = "portable sauna." Opt for blends ≤30% (cotton-polyester ratio 7:3).

Nylon (Polyamide Fiber)
Advantage: 5x more abrasion-resistant than cotton, the top choice for outdoor wear tear resistance.
Limitation: Poor moisture absorption; sportswear should blend with spandex for better breathability.

Spandex (Elastane)
Application: Just 5-10% blending significantly improves elasticity, with yoga pants achieving >90% rebound rate.

II. Regenerated Fibers: Eco-Friendly ≠ Low Quality
Tencel (Lyocell):
Made from eucalyptus fibers, 100% biodegradable, with 50% higher moisture absorption than cotton.

Acetate Fiber:
Drape rivals silk, but breathability is only 1/5 of cotton—use cautiously in summer.

III. The "Three Questions" on Functional Fabrics
How to choose sun-protective clothing?
Look for UPF50+ labels; retested UV protection must remain >40 after 10 washes to qualify.

Are antimicrobial fabrics effective?
Silver-ion coatings offer >99% antibacterial rates, but efficacy declines after 30 washes. Opt for physical antimicrobial methods (e.g., bamboo fiber) for lasting effects.

Is cooling fiber a gimmick?
Jade-particle-coated fabrics reduce temperature by 2.3°C in tests, but loose cuts are needed to maximize the effect.
