Drop-Stitch Fabric | High-performance Inflatable Material | Wonpoong

What is “Drop-Stitch Fabric”?

Drop-stitch fabric is made of two adhesive fabric layers, interconnected by thousands of fine yarns. This structure allows the material to be inflated to high pressure, forming a rigid and stable shape while remaining lightweight. It is widely used in inflatable boats, paddle boards, air mattresses, and various marine products.

Wonpoong Technology

Wonpoong has installed a state-of-the-art manufacturing line, specializing in drop-stitch fabric production. Our advanced coating and laminating systems ensure exceptional bonding strength, durability, and consistent quality.

Okcheon Factory

Our Okcheon factory is a dedicated manufacturing facility for industrial and marine fabrics. Equipped with high-precision machinery, it enables mass production of premium-quality drop-stitch materials with stable performance and reliability.

Why We Are Different

Unlike traditional manufacturing processes, which involve uncontrollable human factors, Simul Technology is meticulously designed and precisely controlled at every stage. Through this highly engineered process, drop-stitch fabric is manufactured as a fully integrated structure, ensuring consistent quality and structural reliability. Simul Technology further optimizes the weight-to-stiffness ratio, enabling the production of materials that are easy to fabricate, lightweight, flexible, yet exceptionally strong, stable, and highly durable, making them suitable for a wide range of demanding applications.

Key Technical Features of Drop-Stitch Fabric

High-Tensile Thread Core

We provide a high-tensile thread core that is lightweight and has excellent flexibility. Our thread core is highly structured to form a rigid yet smooth surface.

High-Density Adhesive Layers

Under controlled conditions, we machine-laminate and heat-press adhesive layers at once. Our high-density adhesive layers are airtight and durable.

High-Performance Surface Treatment

Our treatments are designed to stiffen and strengthen the fabric surface, prevent distortion and bending, improve airtight adhesion, and extend UV resistance.
