In this guide, I’ll break down everything you need to know about leather jacket lining crafted from polyester fabric. From how it’s made to how it’s used. Stick around, and you’ll walk away with a clear, simple understanding.
Polyester Fabric History

Invented by British chemists in 1941, polyester was brought to the United States by the DuPont Corporation and became a popular choice for manufacturing apparel by the 1970s. Today, polyester is the most popular fiber worldwide, surpassing cotton and making up over half of all global fiber production. Due to its durability and shape retention, polyester is a base component for numerous industrial, commercial, and household products.
Different Types of Polyester Fabric?
To learn more about polyester fabric, you should study more about the three main varieties of this fabric:

1. Ethylene Polyethylene
PET, or ethylene polyester, is the most common form of polyester sold today. In most cases, "polyester" and "PET" mean the same thing, even if there are various kinds of polyester.
2. Polyester Made from Plants
The best thing about plant-based polyester is that it breaks down in nature. Plant-based polyester, on the other hand, costs more to create and may not last as long as PET or PCDT textiles.
3. Polyester PCDT
PCDT polyester isn't as well-known as PET polyester, but it's more flexible, which makes it great for some uses. People often choose PCDT polyester for heavy-duty jobs like drapes and upholstery because it lasts longer than PET polyester.
What Is Polyester Made Of?

You might think, Is polyester a synthetic fiber? Yes, polyester is a synthetic fiber made by mixing ethylene glycol and terephthalic acid. The technical name for polyester is polyethylene terephthalate (PET). It’s man-made, not something that comes naturally from animals like wool or from plants like cotton. To keep it simple, polyester starts life as plastic. Specifically, it’s a type of plastic called polyethylene terephthalate (PET), the same stuff used in water bottles. The magic happens when this plastic is melted down and spun into fibers. Those fibers become fabric. That’s your jacket polyester fabric in a nutshell.
What Does 100% Polyester Leather Jacket Mean?

Fabrics made entirely of polyester fibers are labeled 100% polyester. Polyester fibers can also be blended with other materials; for example, poly-nylon is a blend of polyester and nylon. Blending combines the desirable properties of both fibers.
Why Is Polyester Everywhere in Leather Jackets?

So, why do brands use it? Well, for one, polyester fabric for jackets makes things lighter, smoother, and cheaper. You’ll usually find it in the lining. It helps the jacket slide on easily and adds a bit of structure without making things bulky.
Now, if we’re talking about a 100% polyester leather jacket, chances are it’s not real leather. Its faux leather looks like the real thing but is made from synthetic materials (often coated polyester). These leather jackets are budget-friendly, easy to care for, and durable. But, they won’t age or patina like real leather does.
Is Polyester Breathable?

People ask this a lot: is polyester breathable? Honestly, not really. It doesn’t breathe the way cotton or linen does. If you’ve worn a polyester jacket material on a hot day, you’ve probably noticed it feels a bit sticky. It traps heat and doesn’t let moisture escape all that well. But for cooler weather, or as a lining, it does its job just fine.
How Long Do Polyesters Last in Leather Jackets?

Wondering how long do polyester leather jackets last? They’re pretty durable. Polyester doesn’t rip or stretch easily. Faux leather jackets made from polyester won’t fade or peel quickly if you treat them right.
Expect a good 3-5 years of solid wear, sometimes more. They hold up for casual, everyday use. But no, they won’t turn into heirloom pieces like a well-loved real leather jacket might.
What Does Polyester Fabric Feel Like?

If you’re trying to picture it, polyester fabric usually feels smooth, sometimes a little shiny, depending on how it’s made. Think windbreakers, gym clothes, or lining inside jackets. It’s light, holds its shape, and feels cool to the touch. For linings, it works. It helps jackets go on easier and keeps things comfy inside.
Is Polyester Good for Leather Jackets?

Simple answer is yes? Polyester is affordable, holds up well, and keeps its color. It won’t shrink in the wash. It doesn’t wrinkle. For brands making leather jackets at every price point, it just makes sense. Whether it’s the shell of a 100% polyester leather jacket or just part of the lining, polyester is everywhere because it’s practical.
Is Polyester Right for You?

If you want something affordable, lightweight, and easy to care for, polyester works. If you’re looking for breathability, long-term durability, or natural materials… maybe look elsewhere. It really depends on your style and how you plan to wear it.
