• Material:

  • Spunbond Spunlace Non-Woven Fabric: This type, often made from Polyester or Nylon, is much

  • stronger, more cloth-like, and highly durable when wet. It is used in medical fabrics and premium wipes.

  • Specific Requirement: The fabric must be hydroentangled (spunlaced) for strength and have a high

  • wet tensile strength.

• Breathability & Drainage: The fabric must allow water to flow through it easily during the washing and

•  rinsing process. A very tight weave is not desirable.

• Seam Bonding (The Biggest Challenge): The glue used to create the individual pockets must be

•  waterproof and flexible.

  • Polyurethane (PU) Hot Melt Adhesive: This is a strong candidate. Certain types of PU adhesive remain

  •  flexible and maintain their bond after repeated wet/dry cycles.

  • Ultrasonic Welding: This is the ideal method. It uses high-frequency sound waves to melt the fabric

  • strands together, fusing them into a single piece without any glue. This creates a seam that is as strong

  •  as the fabric itself and completely impervious to water, detergent, and agitation. You must ask your

  •  manufacturer if they have this capability.
