Nylon boasts excellent elasticity, making it a favored material in various applications. When it comes to dyeing, the process is remarkably versatile, achievable at relatively low temperatures, starting from 100 degrees Celsius, using neutral or acidic dyes. While nylon may not match polyester's heat resistance, its superior strength and resistance to pilling set it apart in performance.
The dyeing procedure typically involves a high-temperature and high-pressure environment, with temperatures reaching 130 degrees Celsius. Subsequently, the heat-setting process is conducted at temperatures below 200 degrees Celsius, ensuring the fabric's stability and integrity.
On the other hand, polyester, known for its stability, introduces wrinkle resistance and enhanced flexibility when added in small amounts to clothing. However, it is not without its drawbacks, as polyester fabrics can generate static electricity and are prone to pilling. It's worth noting that continuous advancements in polyester technology have successfully addressed and improved these concerns.
Explore the dynamic characteristics of nylon and polyester, discovering the unique benefits each brings to the table. Whether you prioritize elasticity, dyeing versatility, or resistance to wrinkles, understanding the distinctive qualities of these synthetic fibers empowers you to make informed choices for your diverse textile needs.

Physical Property
In the realm of bag manufacturing, nylon Oxford fabric takes center stage for its widespread usage. The tactile distinction between the two primary materials, polyester, and nylon, is notable – polyester tends to have a coarser feel, whereas nylon offers a smoother touch. An intriguing method for identifying these fabrics involves a simple fingernail test: visible marks often indicate polyester, while nylon tends to show less conspicuous signs. However, for a more definitive assessment, the burn test remains a reliable choice.
Delve into the world of fabric selection for bags, exploring the nuanced textures and subtle differences that can influence your preference. Whether you prioritize the robustness of polyester or the sleek feel of nylon, understanding these characteristics enhances your ability to make informed choices in the realm of bag design and manufacturing. Join us on a journey through the tactile world of fabrics, where touch and texture play a pivotal role in crafting the perfect bag.
Chemical Properties:
The simplest way to differentiate between nylon and polyester is through the burn test. Polyester produces a vigorous black smoke when burned, while nylon emits white smoke. Additionally, the residue after burning differs from polyester residue and crumbles when pinched, while nylon residue forms a plastic-like substance. In terms of price, nylon is twice as expensive as polyester. Nylon, when exposed to flame, quickly shrinks and melts into a white, gel-like substance. It melts and drips in the flame, producing no visible flame itself. It is challenging to sustain combustion once removed from the flame. Nylon emits a celery-like odor, and the cooled molten material appears as a light brown substance that is not easily crumbled. Polyester, on the other hand, is easily ignited and melts upon exposure to flame. During combustion, it melts, emitting black smoke and a yellow flame. It releases a fragrant aroma and leaves behind ash in the form of a black-brown solid block that can be easily crushed with fingers.
Performance Differences:
In simple terms, nylon outperforms polyester in terms of various properties, but it comes with a higher cost compared to polyester. Nylon products generally exhibit superior wear resistance, strength, color fastness, and glossiness, and are less prone to developing permanent wrinkles compared to polyester products.
The main differences between fabrics made of polyester and nylon are:
Price: Nylon is approximately twice as expensive as polyester.
Texture: Nylon has a smoother and softer feel compared to polyester.
Abrasion Resistance: The difference in abrasion resistance is negligible.
Elasticity: Nylon has a slight elasticity, while polyester lacks elasticity.
Dyeing Difficulty: Nylon is more challenging to dye compared to polyester.
Material-related Metrics
D: Denier, a unit used to measure the density of textile fibers, representing the weight in grams of the fiber per 9,000 meters (lower denier indicates finer fibers). The formula is D = G/L * 9000, where G is the fiber weight and L is the fiber length. Commonly used for material strength indicators in backpack fabrics, such as 450D and 500D. Materials with a denier higher than 500D are generally used in areas prone to abrasion, like the bottom of backpacks.
T: Tex, abbreviated as "T", a unit used to measure the density of textile fibers. It represents the weight in grams of fiber or yarn over a length of 1000 meters at a specified moisture regain. The formula is T = G/L * 1000, where G is the fiber weight and L is the fiber length.
