A fabric tensile testing machine, also known as a fabric strength testing machine, is a specialized textile laboratory instrument used to evaluate the force a fabric can withstand before breaking. These strength machines are mostly used to test stretching, tearing, peeling strength, set elongation, seam slippage, and elasticity of various materials.
What Is Tensile Strength
Tensile strength is a stress measure, expressed as force per unit area. This strength shows that a material can support without being torn apart. Nowadays, multifunctional fabric tensile testing machines are designed on the basic principles of general strength machines and measure the tensile strength, elongation at break, stiffness, and tear strength of your testing specimen.
Instrumentation Of Fabric Tensile Testing Machine
This textile instrument has several electronic, mechanical, and software essentials that work together to calculate tensile strength and elongation factor of the targeted material. Thisis mainly composed of:
Two clamps (jaws)- upper fixed and lower movable clamp designed to hold the fabric without slippage.
Servo motor- controls the lower clamp by ensuring a precise and constant rate of extension (CRE principle).
Load cells- this sensitive device is attached between the frame and clamp to measure the exerted force precisely.
Computer software- modern tester equipped with a computerized system to monitor the real-time data analysis and record information.
How Does A Fabric Tensile Testing Machine Work?
The Fabric Tensile Testing Machine works simply by clamping the targeted fabric between the two grips and pulling it apart at a controlled speed until it breaks. Imported sensors that are attached to determine the force and rate of extension record the precise force measurements.
There are two modes of tensile testing machines, which include:
- Constant rate of extension (CRE) principle: distance between the two clamps increases at a constant speed while the stretching force to the fabric is continuously measured.
- Constant rate of load (CRL) principle: Here, the force (load) applied to the fabric increases at a constant rate while the extension is being recorded.
CRE is considered the most reliable and well-grounded of the two above because of its precise, repeatable results and compatibility with ASTM and ISO textile standards.
CRE principleThis testing principle works by clamping the fabric between the moving (at a constant rate) and a fixed jaw. As the fabric extends, the sensors measure the force, extension, and stress- strain behavior. This ends when the fabric breaks.
Over the years, tensile testers have evolved from simple to highly precise and reliable systems, with the use of digital and automated controls, which are among the characteristics of DaRong fabric tensile tester. These tester, unlike the old ones, provides you with the microprocessor-controlled system with a fixed speed that gives high repeatability factors with low variation in consistency.
Why Do We Need A Tensile Tester?
The testing of tearing strength and peeling strength is required to determine the fabric´s ability to hold up the bonded layers. Measuring the tear strength will help the engineers to predict with the real-world stressors that cause tears and abrasions. In the same way, peeling strength testing is essential for understanding the adhesion quality and long-term stability of the layered fabric.
These tests use the modernized and precise load cells with a constant rate extension system to record accurate data and give the most reliable results.
ISO, AATCC, ASTM, JIS, GB/T, DIN, and all other testing organizations are compatible with these testing machines, and results are reliable.
What Does The Fabric Tensile Testing Machine Do?
This specialized textile machine accurately measures:
Tensile strength: the maximum force the fabric can withstand before tearing apart.
Elongation: how much the fabric is elongated before breaking.
Tearing strength: the strength required to make a tear in the fabric.
Peeling test: It determines the force required to separate the two bonded layers of a textile material.
