Industrial Electrospinning Platform
Changzhou Yijin Intelligent Manufacturing Technology Co., Ltd. focuses on electrospinning industrialization, building high-output, ultra-wide, integrated equipment systems and high-end nanofiber membrane products for new energy, biomedicine, intelligent sensing, catalytic chemistry, fluid filtration, oil-water separation, and energy-saving environmental applications.
Company Positioning
Located in Zhongrui Industrial Park, Xinbei District, Changzhou, Yijin focuses on high-efficiency wide-width electrospun membrane manufacturing. With electrospinning equipment industrialization as its entry point, the team develops T-Flechette electrostatic fiber jet technology and builds process capability for mechanical strength, quality stability, and distributed performance control under wide-width production conditions.
The company has formed three main product directions: waterproof breathable apparel membranes, collagen medical dressings, and polyimide films for electronic skin. It also supports central control units, laboratory platforms, pilot bases, and nanoscale fiber characterization to provide customers with support from materials to equipment.
Main Products
The current product portfolio focuses on waterproof breathable membranes, collagen medical dressings, and polyimide films for electronic skin.
Designed around hydrostatic pressure, moisture vapor transmission, basis weight, and width. Reference data includes 13,498 mmH2O hydrostatic pressure, 220,000 g/24h*m2 moisture permeability, 10-15 g/m2 basis weight, and 1.6 m width.
Uses natural polymer materials such as sodium alginate, natural cellulose, hyaluronic acid, gelatin, collagen, chitin, and derivatives to prepare nanofiber materials through electrospinning.
PI films provide flexibility, thermal resistance, and dielectric stability, with tensile strength up to 200 MPa, thickness of 10-20 um, and operating temperature from -269 to 400°C.
Technology Route
Waterproof breathable membranes compete on pore structure, flux, waterproof pressure, durability, and environmental compliance. The two routes differ in process maturity, structural design space, functional integration, and industrialization control.
Stretched films generally form microporous structures through stretching or phase separation. The route is mature and suitable for stable mass production, with established supply chains, clear lamination processes, and controllable cost models.
Electrospinning directly builds micro-nano fiber networks with high porosity, high specific surface area, and tunable structures, enabling control over fiber diameter, pore distribution, layer thickness, and functional components.
Platform Capability
Yijin builds its electrospinning industrialization base around central control units, laboratory platforms, pilot bases, and nanoscale fiber characterization. External communication focuses on whether materials can be made, samples can be verified, processes can be scaled, and batches can remain stable.
