Wholesale Channel Fabric (Puffer Fabrics)

Channel fabrics, the ones typically used in down jackets, make use of lightweight yet durable fibers, such as nylon or polyester. This type of fabric is primarily produced in China since the country is one of the biggest manufacturers of both nylon and polyester fibers.

What is channel fabric (aka. puffer jacket fabric, down jacket fabric)?

The channel fabric is named as such because it features several “channels” that can be filled with some sort of filling. This type of fabric is typically used in jackets, especially puffer jackets, since they require an extra layer of heat insulation.

The outer layer of the channel fabric typically uses two kinds of fibers: nylon and polyester. Nylon is a popular fiber of choice for many products, especially outdoor gear — this is because it’s quite strong, but at the same time, it’s also lightweight. However, nylon doesn’t breathe well, so it can take on a lot of moisture, making it unsuitable for humid climates. 

On the other hand, polyester is more breathable and durable than nylon, but it doesn’t tend to do well when it gets wet. Oftentimes, nylon and polyester are blended together to get the best of both worlds — the fabric will now be stronger and breathable at the same time. 

Another textile that’s sometimes used in channel fabric is fleece. Fleece inherently has warming capabilities, so it works well as a casual channel fabric. That said, it also doesn’t perform well when wet, and that’s why it’s usually overlooked in favor of the nylon-polyester blend. 

What materials are used to stuff the channels in a channel fabric?

There are different materials as stuffing for channel fabrics. The first is called a down fill — this is a lightweight stuffing that is able to loft open up and create pockets of air trapped in between the feathers. Because of this, the fabric creates heat and can warm up the wearer. Down fill is preferred if the channel fabric is used to produce hiking jackets.

The second type of stuffing is synthetic fill. This kind of fill doesn’t compress and can start to lose the ability to trap body heat. Synthetic fill is perfect for humidity.

What is channel fabric used for?

Channel fabrics are primarily used in down jackets or puffer jackets. The air pockets in this type of fabric allow designers to stuff filling inside to make the jackets perfect for cold weather.
