JSF08 high-precision short fiber morphology and mechanical properties tester

How to choose a textile material tensile tester？

• No textile instrument can be used to measure the tensile properties of all textile materials. Different textile materials are suitable for different stretching instruments.
• The stretching measurement of textile materials can be carried out in three directions, which are mainly distinguished by direction: 1) stretching and compression in one direction, such as a single fiber tensile tester; 2) Stretching and compressing in two directions, such as biaxial stretching instruments; 3) Stretching and compressing in two directions and bursting in a third direction; For example, a three-dimensional mechanical measuring instrument.
• According to the force value of material fracture strength, measuring instruments are divided into: micro force stretching devices, such as instruments used to measure quasi nanometer level fibers (Dalian University of Technology's nanofiber stretching and compression bending instrument); General force stretching devices, such as single fiber strength testers; High strength stretching device, such as three-dimensional mechanical stretching device (Beijing Bamboo and Vine Network Center).
• Different instruments can also be selected based on the type of chuck: single fiber tensile tester with pneumatic chuck used for ordinary natural fibers; Instruments with special card slots suitable for fibers with relatively high strength in artificial fibers (such as the bamboo and wood short fiber stretching device at Beijing Bamboo and Vine Center and the carbon nanotube fiber stretching device at Tianjin University; manual stretching instruments suitable for short and brittle quasi nano scale fibers (Dalian University of Technology); Pneumatic chuck suitable for bundling fibers; A stretching device for clamps suitable for high-strength fabrics (Beijing Bamboo and Vine Center);
• Depending on the observation system, different instruments can also be selected: 1) Single fiber tensile apparatus without observation system; 2) A quasi nanofiber tensile tester with a lens for local observation; 3) A short fiber stretching instrument with two lenses for local and panoramic observation; 4) A 3D mechanical stretching device equipped with high-speed cameras (Beijing Bamboo and Vine Network Center).
• According to the speed of the stretching device, it can be divided into: slow stretching instrument (nanofiber quasi stretching device); Rapid tensile tester (3D mechanical testing device).
• In short, according to different materials, different products can be selected, different clamps, digital observation systems, stretching speed and accuracy can be chosen, and suitable instruments can also be selected based on different collected force values. Our company can process textile material tensile testers that meet your needs according to different standards.

Fiber measuring instrumentUsed to measure the mechanical properties (modulus, fracture energy, fracture elongation, etc.) and appearance (fiber morphology, diameter, length, fracture morphology, and fracture process) of single fibers under different experimental parameters (such as tensile speed, spacing), characterize the characteristics of fiber materials through the measurement of these parameters, and provide guidance and reference indicators for the application and trade process of fiber materials.

JSF08 high-precision short fiber morphology and mechanical properties tester:

There are widely used experimental instruments for measuring the strength of conventional fibers. However, for materials such as bamboo and wood fibers, which have small fineness, high strength, short length, and are brittle and easy to break, the preparation of samples in experiments is a major problem. At the same time, corresponding stretching devices are also required for this special material experiment. This stretching device was developed in this context, using a special precision chuck to clamp the sample, ensuring the fiber is straightened and does not slip during the stretching process. This instrument observes the surface morphology of fibers and captures the stretching process of fibers through a horizontal optical measurement system, and accurately positions bamboo fiber samples on the chuck through a vertical optical system.

The specific parameters are as follows:
Magnification of lens: Horizontal optical system: 12 pixels/micrometer Vertical optical system: 0.7~4.5X
Range and accuracy of 2 forces: 4.903N and 980.7mN, with a force reading accuracy of one ten thousandth of the range.
4 guide rails: precision linear ball guide rail, stroke 25mm
5 screws: pitch 0.25mm
6 Precision Drive Motor/Frequency Divider Control Card: The smallest step is 0.1125 degrees, and the highest single step calculation has a physical accuracy of 0.068 micrometers
7 Short fiber stretching fixtures, fiber spacing distance: 0.8mm. 8 Two sets of precision three position adjustment systems, one set of two-dimensional adjustment system Capable of monitoring both horizontal and vertical directions

1. Use special clamps to measure the tensile properties of short fibers (such as bamboo and wood short fibers).
2. The stretching speed, spacing, and maximum range of motion of the fibers can be adjusted.
3. By using a digital optical system with two directions, the sample can be observed through local magnification and panoramic magnification.
