■ Introduction

● Polyimide Fiber: Combines warmth, skin-friendliness, health care, flame retardancy, and weather resistance. Recognized for broad application prospects as both structural and functional material.

■ Technological Advancement

● R&D Efforts: Significant advancements have been made to transition from industrial to civilian applications, leading to the development of "polyimide silk" textile fiber material, a high-performance native energy fiber.

■ Molecular Structure

● Unique Composition: Bannor advanced materials’ polyimide fiber has a unique molecular structure and elemental composition that absorb body and environmental heat.

● Far-Infrared Rays: Emits beneficial far-infrared rays that enhance microcirculation without the addition of ceramic powder, ensuring long-lasting infrared effects even after washing and wearing.

■ Performance Parameters

● Thermal Conductivity: Lower than common fibers, making it difficult for body heat to conduct outward.

● Moisture Regain Rate: Suitable for close contact with the skin.

● Ecological Textile Certification: Antibacterial sensitivity index and more.

■ Native Far-Infrared

● Wavelength Range: Emits far-infrared wavelengths within 4-16μm range.

● Emissivity and Absorption Rate: 88%.

● Irradiation Heating Rate: 0.129°C/s.

● Microcirculation Perfusion Index: 114.23%.

● Durability: Properties do not degrade after 50 washes.

■ Baby-Grade Skin-Friendliness

● Smoothness: Smoother than cashmere, comfortable to wear, hypoallergenic.

● Certifications: Passed Swiss textile testing institute's oeko-tex baby-grade ecological confidence textile certification and GSG sensitive skin tests.

● Suitable For: Baby-grade underwear.

■ Health and Safety

● EU Tests: Passed tests for 161 highly concerned substances in textiles with no detections, exceeding EU import requirements for textiles.

■ Antibacterial Properties

● Efficacy: >99.99% against Escherichia coli ATCC 25922, Staphylococcus aureus ATCC 6538, and Candida albicans ATCC 10231.

● Natural Color: Golden or black without dyeing.

■ High-Performance Insulation

● Thermal Conductivity: Lower than common fibers.

● Far-Infrared Energy: Inherent far-infrared energy enhances fabric’s heat retention.

● Humidity and Wet Conditions: Maintains insulation.

■ High-Performance Flame Retardance

● Limiting Oxygen Index: 38, non-flammable.

● High-Temperature Performance: Almost shapeless at high temperatures, self-extinguishing upon removal from fire.

● Strength at 300℃: Good strength, does not shrink or break strongly.

● Flexibility at -269℃: Remains flexible in liquid nitrogen.

● Applications: Excellent material for home fire prevention and special environment industrial clothing.
