Backpacks are a common item in everyone’s lives, whether children go to school or go on outdoor hiking adventures. So have you ever considered what material your backpack is made of? Among the many materials available, 600D polyester stands out as a reliable and versatile choice. In this guide, we will give you a detailed analysis of the uses and advantages of 600D polyester fiber material in backpacks.
What is 600D polyester?
First, we need to know what polyester is. Polyester is a synthetic fabric known for its durability, abrasion and tear resistance. What is “600D”? The name “600D” refers to the density of the fabric. Many people may think that D is the density, but this is not true. “D” stands for denier, a unit of measurement that indicates the thickness of a single thread. If a thread weighs 9000 m/g, we call it denier. The lower the D, the lower the density and the thinner the line. For example, 210D polyester has thin threads and is suitable for the interior of bags. 900D or 1000D thread is thicker, harder and more durable, and can be used to make the bottom of the bag.

Advantages of 600D polyester
Strength and Durability
One of the most notable features of 600D polyester is its excellent strength-to-weight ratio. It has good durability despite its light weight and can withstand various harsh challenges, making it the backpack of choice for many outdoor adventures. It can provide reliable protection for the items in the backpack.
Easy Maintenance
The 600D polyester fiber itself is resistant to mold, mildew, and UV radiation, ensuring your backpack remains in top condition even after extended use. Cleaning is simple and usually only requires mild soap and water to remove dirt and stains.
Affordable Price
While 600D polyester offers so many benefits, it also comes at an affordable price, making it suitable for backpackers of all budgets. FEIMA is a Chinese factory that mass-customizes bags. We can control costs at a relatively low level, so our customers can buy at a lower price and ensure good quality.
Disadvantages of 600D polyester
Limited Waterproofing
Although 600D polyester fiber is waterproof, it does not provide complete waterproofing. If it is exposed to heavy rain or long-term humid conditions, water will penetrate into the fabric and soak the contents of the backpack.
Limited Breathability
Polyester fabrics, including 600D polyester, don’t breathe as well as natural fiber materials like cotton or wool. Wearing it in a hot or humid environment may hinder perspiration.
Easily Prone to Static Electricity
Polyester is prone to static electricity when it rubs against other items. Especially in winter when the climate is dry, it is easy to get electrostatic shock.
What are the differences between 210D, 600D and 1000D polyester?
210D polyester fiber is lightweight, soft and thin. It is not as durable and tear-resistant as 600D polyester. It is often used as the lining of foldable backpacks or backpacks.
600D polyester is less durable than 1000D polyester but is lighter, striking a balance between weight and durability, making it a versatile choice for a variety of applications, including backpacks and school bags.
1000D polyester has the best abrasion resistance, but it is also the heaviest. Perfect for military gear, tactical backpacks and duffel bags..
