How to Identify Polyester Fabric: A Guide for Shoppers

2023-04-24 | Textile Fabric Knowledge

When it comes to purchasing clothing or home textiles, people are often faced with many different fabric choices. One common synthetic fiber is polyester. This fabric has many advantages, such as being durable, easy to clean, and maintaining its shape. However, sometimes it is not easy to distinguish polyester from other fabrics. In this article, we will explore how to identify polyester fabric.


First, we need to understand the characteristics of polyester. Polyester is made from polyester fibers and typically has a certain amount of luster and a soft hand feel. It can imitate natural fibers such as silk, cotton, and wool and is often blended with other fibers to achieve better performance.


However, relying solely on the feel of the fabric cannot determine if it is polyester because other fibers can also have a similar hand feel. Therefore, other methods need to be used to identify polyester. Here are some commonly used methods:


Observe the label: When purchasing fabric, it is important to check the fabric label. If the fabric contains polyester, this information should be noted on the label. Typically, the label will indicate the percentage of fabric composition and the types of fibers contained. If you are unsure, you can look up the chemical name for polyester, "polyester".


Use a burn test: A burn test is a simple yet effective method for identifying polyester fabric. Take a small piece of untreated fabric, ignite one end, and observe the way it burns and the color of the smoke. Polyester smoke is white and has a pungent odor. It will continue to burn after the flame is extinguished, leaving a hard, black, spherical object.


Use a fluorescence test: A fluorescence test is a very common method used to determine the presence of polyester. Shine some ultraviolet light on the fabric. If the fabric emits blue or white fluorescence, it may contain polyester.


In summary, polyester is a common synthetic fiber with many advantages but can be difficult to distinguish from other fabrics. By checking the label, using a burn test, and a fluorescence test, you can identify polyester fabric. When purchasing fabric, try to learn as much as possible about the fabric composition and properties to ensure that your choice meets your needs.
