We use a material that is a part of a design to turn patients in bed so they don’t develop pressure ulcers.
The material allows easy movement from side to side (x direction) to “turn” them onto fabric covered wedges. But the fabric prevents the patient from sliding down the bed (y direction). Patients slide down because the torso is inclined at 30 degrees to prevent pneumonia.
I believe the fabric is a polyester typically used for lint brushes.
