Double-Wall Fabrics: Back to Basics

The construction of double wall fabrics is a new concept. The surfaces of the fabric are connected to each other through vertical pile fibers. Basically, it is tons of fine polyester threads woven into the bottom of the base material to make sure when the threads hit their maximum length, there will be no over-inflation. In this article, we are going to get a deeper insight into double-wall fabrics. Read on to know more.

There are a lot of reasons to use polyester. For instance, it’s durable, strong and features a small degree of stretch. So, the double-wall fabrics may offer great resistance, integrity, and durability. Apart from this, the interstitial construction space may be filled up using foam for providing synergistic support for the vertical piles.

On the other hand, the double-wall fabric is an ideal choice for swimming pools, mattresses, boat bottom, and inflatable SUPs. The reason is that they feature weather resistance performance, anti-aging performance, self-cleaning, great stability, high quality, and high strength.

Types of Raw Material Base Fabric:

Primarily, there are two kinds of base fabrics as far as drop-stitch material is concerned. They are called woven knitting and warp knitting. Below is the description of both the types for your understanding.

Woven vs Warp-Knitting

Warp-knitting type is the most widely used type that covers a wide spectrum of inflatable products. And this type features one thread on one end and then two threads on the second end. Also, the warp-knitting machine is a small setup, costs low and offers high production speed. As a result, manufacturers can enjoy lower costs as far as the raw material is concerned. On the other hand, there are some downsides to this type. One disadvantage is that the weight of the material is quite high.

On the other hand, the woven base fabric is an ideal choice for inflatable products. The reason is that inflatable products can’t stand the test of time if they are not stiff enough. In fact, they should offer superior stiffness for the best performance.

The difference between this type and the other type is that it features just one thread that connects two layers of the base fabric. However, the cost of the base fabric woven setup is a lot higher than the warp-knitting setup. Generally, the cost is 4 to 5 times higher. Besides, the production speed is also slower. So, this is a downside. However, the major advantage of this setup is that the weight of the woven base fabric is 30 to 40 times less than that of warp-knitting.

The Double-Wall Fabric Uses:

There are many uses of double-wall fabric. However, we have listed some of the most common uses below.

• Inflatable dock systems

• Inflatable docks

• Air track

• Water mat

Aside from these, there are many other applications of this fabric type. But these are the most common uses.

So, this is a short description of double-wall fabrics. If you want to find out more, you can consult a professional. This will help you know more about it.
