AI Technical Summary
Existing medical nonwoven fabrics are prone to adsorption and touch the skin or wounds when the patient's blood splashes, resulting in an increase in surgical infection rate.
A medical breathable non-woven fabric is designed, including a sequentially stacked non-woven fabric layer, a filter cotton, an antibacterial layer and a waterproof layer. The filter cotton forms breathable holes from cotton threads that interlaced horizontally and longitudinally, and the composite fabric is extruded into molding through a preparation device.
When the fabric adsorbs liquid, the waterproof layer blocks most of the liquid, and the antibacterial layer and filter cotton absorb a small amount of liquid, reducing contact with the skin or wound, reducing the risk of infection, and improving the breathability and comfort of the fabric.
