What is drop-stitch fabric?

Drop-stitch fabric is two layers of coated base cloth joined by tens of thousands of internal threads of equal length. Inflated, those threads hold the two faces parallel, turning the fabric into a rigid panel with defined thickness.

How is drop-stitch fabric made?

The two faces and the connecting threads are woven or knitted together on a specialised machine, then coated with PVC or TPU. The thread structure is created during weaving and cannot be added afterwards.

What thickness of drop-stitch fabric is available?

Commercially available chamber depth runs roughly five to thirty centimetres, covering paddleboards, boat decks, gym mats and most shelter walls. Anything outside that band should be confirmed with the mill before you design around it.

Is TPU better than PVC for drop-stitch?

TPU stays flexible in cold, ages better under UV and is lighter for the same strength; PVC costs less, welds faster and offers a wider colour range. For temperate seasonal use PVC is usually the right commercial answer.

Pvc Coated Fabric

PVC 涂层布

Single-layer technical fabric with a PVC coating, used for inflatable products and covers.

PVC coated fabric — product view on a plain background — 产品图

PVC coated fabric deployed on site, in use — 现场使用

典型场景

Outer skin for inflatable products
Tarpaulins and covers
Surface layer for water products
Cost-sensitive volume production

为什么选充气结构

Cheaper than TPU with a mature process
Welds readily by high frequency
Wide range of colours and weights

不适合什么

Low-temperature flexibility and ageing resistance are inferior to TPU. Cold-climate and high-UV applications should be assessed or specified in TPU instead.
