3. Manufacturing Process: Ensuring Medical-Grade Quality
The production of polyester spunbond nonwoven fabric for medical protective suits requires precision, cleanliness, and adherence to strict protocols. WINIW’s manufacturing process is designed to meet these requirements, combining advanced technology with rigorous quality control:
3.1 Raw Material Preparation and Melting
The process begins with the careful handling of 100% new slice polyester chips. These chips are inspected for purity and uniformity before being fed into a hopper. From there, they are transported to an extruder, where they are melted at temperatures between 250–270°C. This precise temperature control ensures the polymer flows smoothly without degradation, which could compromise the fabric’s strength or introduce harmful byproducts.
3.2 Filament Extrusion and Drawing
The molten polyester is forced through a spinneret—a metal plate with thousands of tiny holes (0.2–0.4mm in diameter). As the polymer exits the spinneret, it forms continuous filaments, which are immediately cooled by a stream of filtered air to solidify them. The solidified filaments are then stretched (drawn) by a series of rollers at varying speeds, aligning the polymer molecules to enhance tensile strength. This drawing process reduces the filament diameter to 15–30 micrometers—ideal for creating a fine, uniform fabric with excellent barrier properties.
3.3 Web Formation and Thermal Bonding
The drawn filaments are spread into a uniform web using high-pressure air jets, ensuring even distribution across the full width of the fabric (up to 3400cm). This web is then passed through heated calender rollers, which apply heat (180–200°C) and pressure to bond the filaments together at their contact points. Thermal bonding eliminates the need for adhesives, which could introduce contaminants or degrade in medical environments. The roller pattern is carefully chosen to balance barrier efficiency (small, dense bonds) and breathability (controlled porosity).
3.4 Post-Treatment and Sterilization Readiness
After bonding, the fabric undergoes optional post-treatments to enhance its performance for medical applications:
- Antistatic Treatment: Reduces static electricity, preventing the fabric from attracting lint or particles that could compromise sterile environments.
- Hydrophilic Treatment: Improves moisture wicking, enhancing comfort by drawing sweat away from the skin during extended wear.
- UV Stabilization: Protects the fabric from degradation during gamma radiation sterilization.
The fabric is then trimmed to the desired width, wound onto clean, sanitized cores, and packaged in sealed, moisture-resistant bags to maintain sterility until use.
3.5 Quality Control and Testing
Every stage of production is monitored by automated sensors and manual inspections. Key tests performed on finished fabric include:
- Tensile strength and elongation (ASTM D5035)
- Air permeability (ASTM D737)
- Hydrostatic pressure resistance (AATCC 127) – measures barrier against liquid penetration
- Linting (ASTM F51-13) – critical for sterile environments
- Bacterial filtration efficiency (BFE) and viral filtration efficiency (VFE) testing
Only fabric that meets all medical standards proceeds to shipping, with each roll accompanied by a certificate of analysis (COA) documenting its test results.
