Kaolin hemostatic gauze is used in emergency, surgical, and tactical medicine settings for rapid bleeding control — kaolin particles help activate the blood clotting process on contact with the wound. Many of these products also include an X-ray detectable (radiopaque) thread woven into the gauze, so surgical teams can confirm none of the material was left inside a wound after treatment. Producing this type of gauze requires equipment that can unwind the base material together with the radiopaque thread, ultrasonically weld the thread in place, then apply and control liquid before drying — all in one continuous, synchronized process.
This guide covers the technical specifications and working principle of the ZXJ YWJ-BFE 50, a kaolin hemostatic gauze folding machine built for this specific product type.
How the Kaolin Hemostatic Gauze Folding Machine Works
The YWJ-BFE 50 runs a fully integrated process: raw non-woven material and the radiopaque thread unwind together, and the thread is bonded to the material first using S-shape ultrasonic welding.
The welded material then passes through a spray station where liquid is applied and circulated, followed by a squeeze station that controls how much liquid the material retains.
From there, the material moves through a vertical drying oven, where a zigzag feed path extends the effective drying length within a compact footprint. After drying, the material reverses direction, is pulled through a traction stage, and is precision cut to length by a servo-controlled system before being Z-folded along its length and conveyed out at an adjustable speed.
Unlike folding machines designed for wider sheet products, this machine folds only in the length direction — the width is not folded, which matches the narrow-strip format typical of packable gauze products.ackable gauze products.
Key Technical Features
- Integrated continuous production: thread welding, liquid application, liquid control, drying, length cutting, folding, and conveying are combined into a single line, reducing intermediate handling steps
- Inline liquid application and control: spray-then-squeeze method keeps liquid content consistent across the material, which supports stable downstream drying and welding
- Vertical zigzag drying: extends the effective drying path length within a compact machine footprint
- S-shape ultrasonic thread welding: bonds the radiopaque thread to the base material in a continuous, stable position
- Servo length control with Z-fold: produces consistent cut lengths and neatly stacked folded output for downstream packaging
- PLC and touchscreen control: centralized parameter settings with visual monitoring of the production process
The exact weight for either product depends on your target market’s price point and durability expectations, and should be confirmed against your specific material supplier’s product line.
