Specifications

Critical annealing temperature

{'zh': '80', 'en': '80'} °C

Advantages

Temperature-tunable crystallization

Annealing temperature determines the crystallization mechanism: below 80 °C secondary crystallization forms thicker lamellae, while above 80 °C spontaneous crystallization forms thinner lamellae, enabling tunable crystallinity and mechanical properties.

Clear mechanistic transition

Gaussian fitting revealed that the two crystallization mechanisms occur simultaneously with rates dependent on annealing temperature, providing a theoretical basis for process optimization.

Applications

• Polymer Fibers and Non-wovens：Tailor mechanical properties of filtration and packaging non-wovens via annealing.
• Polyolefin Material Modification：Control crystallization mechanism by temperature to optimize crystallinity and strength of polyolefin products.
• Flexible Wearable Textiles：Achieve LDPE fabrics with varying softness and strength for wearable device requirements.
