Applications

Excellent Physical and Mechanical Properties

High Strength and Durability ：After hydroentanglement, the breaking strength of polyimide fibers in both warp and weft directions is significantly improved (for example, the warp breaking strength of 100 g/m² specification reaches 448 N, and the weft breaking strength is 102 N). The flexible entanglement process does not damage the fiber structure itself, maintaining high resilience and tear resistance.

Extreme Temperature Resistance ：It can be used stably in the range of -200°C to 300°C without embrittlement or softening, suitable for high-temperature or low-temperature environments.

Top-Level Flame Retardant Performance

The limiting oxygen index (LOI) is >30%. When encountering fire, there is no melting, no smoldering, and the damage length is <2 mm, far exceeding ordinary flame-retardant materials.

Excellent Chemical Stability

Resistant to strong acids (30% HCl, 40% HNO₃), strong alkalis (20% NaOH), and organic solvents. The mechanical property attenuation rate is <10% after immersion, suitable for chemical protection scenarios.

Comfort and Design Flexibility

Skin-Friendly and Antibacterial ：Plasma treatment can significantly improve surface hydrophilicity (contact angle reduced from 121.5° to 68.5°) and impart antibacterial properties (64.3% inhibition rate against Escherichia coli, 91.6% against Staphylococcus aureus).

Breathable and Moisture-Permeable ：The three-dimensional network structure of the fiber provides high breathability (>1000 L/m²/s) and has moisture-wicking and quick-drying properties.
Customization supported.
Basis weight: 70g, width: 1.5m.
High-end protective equipment
Chemical protective suit ：As a skeleton layer material, used in Class A chemical protective suits, combining flame retardancy, corrosion resistance, and lightweight properties (such as fire fighting and nuclear industry).
Special filter material ：Combined with electrostatic electret technology, it is made into a high-efficiency filter layer for filtering high-temperature flue gas or chemical dust (PM0.3 filtration efficiency >99.9%).
Medical and hygiene materials
Functional dressings and surgical gowns ：Utilizing its antibacterial and hypoallergenic properties, it is used for wound dressings (promoting serine absorption to accelerate healing) and surgical isolation layers.
Microecological balance hygiene products ：Treated with functional auxiliaries such as chitosan/octanoylhydroxamic acid, it can regulate skin flora and is used in high-end sanitary napkins, wet wipes, etc.
Industrial precision field
Aviation/electronic wipes ：High liquid absorbency (penetration increased by 181.9%) and low reverse osmosis characteristics, cleaning precision instruments without leaving residual fibers.
High-temperature sealing and insulation materials ：As a composite reinforcement layer, used in engine heat shields or battery fireproof diaphragms.
Advanced composite materials
Multi-component functional composite ：For example, a three-layer structure of "flame retardant-antibacterial-filtration" (PI flame retardant surface layer, antibacterial double-component fiber in the middle, and electrostatic electret polyester bottom layer) achieves multi-functional integration.
Bionic structural design ：Such as peach-skin-like finishing (brushing + nano PU coating), improving the feel and fit of the garment base fabric.
