■ 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.
