Textile Tensile Testing Machine

Testing Applications of Textile Material Tensile Testing Machine

Yarn Testing

• Breaking Strength Testing: This measures the maximum force that a yarn can withstand until it breaks during stretching. It is a crucial indicator for evaluating the strength of the yarn and directly affects the durability of the fabric.
• Elongation at Break Testing: This reflects the elongation ability of the yarn before breaking. For some fabrics that require elasticity, such as stretch fabrics, the elongation at break of the yarn is a key parameter.
• Relationship between Twist and Strength Testing: This studies the influence of yarn twist on its strength. By adjusting the twist and testing the corresponding strength, it provides a reference for the yarn production process.

Fabric Testing

• Tensile Strength Testing: This assesses the fabric's ability to resist tensile failure. For clothing fabrics, home textile fabrics, etc., the tensile strength determines their durability during use.
• Tear Strength Testing: This simulates the tearing situation of the fabric when it is affected by sharp objects in actual use, and tests the fabric's ability to resist tearing. For fabrics that often need to withstand friction and tearing, such as denim, the tear strength is an important performance indicator.
• Bursting Strength Testing: By applying pressure perpendicular to the fabric plane, this tests the fabric's ability to resist bursting. It is commonly used to evaluate the performance of knitted fabrics, non - woven fabrics, etc.

The maximum range varies among different models of textile material tensile testing machines. Common ranges include 500N, 1000N, 5000N, etc. You can select a testing machine with an appropriate range according to the maximum expected tensile force of the textile material to be tested. Generally, it is recommended that the test force value be within 20% - 80% of the range to ensure measurement accuracy.

For high - quality textile material tensile testing machines, the force measurement accuracy can usually reach within 1%. Some high - precision devices can even achieve 0.5%. High - precision force measurement ensures an accurate evaluation of the tensile properties of textile materials and provides reliable data for product quality control.

Absolutely. The textile material tensile testing machine is equipped with various fixtures suitable for different yarns. Whether they are natural fiber yarns (such as cotton yarn, wool yarn) or chemical fiber yarns (such as polyester fiber yarn, nylon yarn), tests such as breaking strength and elongation at break can be carried out. You just need to select the appropriate fixtures and test parameters according to the thickness, material and other characteristics of the yarn.

The fixtures of the testing machine are usually designed with adjustable structures. For fabrics of different widths, the clamping width of the fixture can be adjusted according to the actual situation. For fabrics of different thicknesses, adaptation can be achieved by replacing clamping blocks of different thicknesses or adjusting the clamping force of the fixture, ensuring that the fabric can be firmly clamped and the force is evenly distributed during the test.

What is the adjustment range? The stretching speed can be adjusted. Generally, the adjustment range is between 0.01mm/min - 500mm/min. Different textile materials and test standards have different requirements for the stretching speed. For example, when testing elastic fabrics, a slower stretching speed may be required, while for ordinary fabrics, the test speed can be relatively faster. Users can flexibly set the speed within the specified range according to actual needs.

The testing machine is equipped with a professional data collection and processing system. It can collect data such as force values and displacements in real - time and automatically draw force - elongation curves, which is convenient for visually displaying the stretching process of the material. At the same time, the system can automatically calculate various tensile performance indicators, such as breaking strength, elongation at break, tensile strength, etc., and can generate standardized test reports according to different standards. It also supports data storage and querying, which is convenient for subsequent analysis and comparison.

The equipment is relatively easy to operate, equipped with an intuitive operation interface and detailed operation instructions. However, for first - time users, professional training is recommended to ensure that they can correctly set test parameters, operate the equipment, and handle possible problems. The training content usually includes the basic principles of the equipment, operation procedures, maintenance points, etc. After training, operators can quickly get started and use the equipment proficiently.

Daily maintenance mainly includes regularly cleaning the equipment to prevent dust and debris from entering the interior of the equipment and affecting its performance; checking the wear of the fixtures and replacing them in time if necessary; regularly calibrating the force sensor and displacement sensor to ensure measurement accuracy; lubricating the transmission components (such as lead screws, guide rails) to ensure smooth operation of the equipment; in addition, attention should also be paid to the storage environment of the equipment to avoid damage to the equipment caused by adverse environments such as humidity and high temperature.

When a fault occurs in the testing machine, first check the error message of the equipment and conduct a preliminary inspection according to the prompt. Common faults and solutions are as follows: If the force value display is abnormal, it may be a problem with the force sensor or loose connection lines, and the sensor and lines need to be checked; if the stretching process is not smooth, it may be due to insufficient lubrication of the transmission components or blockage by foreign objects, and lubrication and cleaning are required; if the equipment cannot start normally, check whether the power connection and control system are normal. If you encounter problems that cannot be solved by yourself, you should contact the after - sales technical support personnel of the manufacturer in time.

The manufacturer provides comprehensive after - sales services. This includes a one - year warranty period. During the warranty period, if there are quality problems with the equipment, free repair or replacement of parts is provided. Technical consultation and remote guidance services are offered to help users solve problems encountered during the use process. Regular follow - up visits are made to users to understand the equipment usage situation and collect feedback. In addition, equipment upgrade services can also be provided to meet the ever - changing testing needs of users.
