Frequently Asked Questions | FAQs

What is breaking extension?

The breaking extension of textile fibers refers to the elongation or extension a fiber undergoes before it breaks under tension. It is a measure of the ability of a fiber to stretch without breaking and is an important property in determining the performance and durability of textiles.
When a tensile force is applied to a fiber, it starts to elongate until it reaches its breaking point, at which it fractures. The breaking extension is the percentage increase in length that occurs just before the fiber breaks. It is expressed as a percentage of the original length.
Different fibers have varying breaking extensions, which can be influenced by factors such as fiber composition, molecular structure, and processing techniques. Natural fibers like cotton and wool generally have lower breaking extensions compared to synthetic fibers like polyester and nylon. However, the specific breaking extension values can vary depending on the particular fiber type and its manufacturing process.
Understanding the breaking extension of textile fibers is essential in designing and producing textiles that can withstand various forms of stress during their use, such as stretching, pulling, or bending. Fibers with higher breaking extensions are typically more flexible and can withstand greater strain before failure, making them suitable for applications where durability and resilience are important, such as in sportswear or technical textiles.
