    Digital Elmendorf Tearing Tester

     

    Digital Elmendorf Tearing Tester is a precision instrument used to measure the tear strength of materials like woven fabrics, paper, plastic films, and nonwovens. It determines how much force is required to continue tearing a pre-slit sample.

    Key Functions of Digital Elmendorf Tearing Tester:

    – Measures propagation tear resistance, not initial tear.

    – Uses a pendulum to apply force; the energy lost during tearing is calculated to determine tear strength.

    – Equipped with a digital display for direct reading of results in grams or millinewtons.

    Core Components:

    – Pendulum Arm: Applies tearing force.

    – Clamps: Secure the sample before and after the tear.

    – Cutting Blade: Creates a precise slit at the start of the test.

    – Digital Display Unit: Shows the tearing force result clearly and instantly.

    – Counterweights: Optional weights for increasing test range (for stronger materials).

     

    Applications of Digital Elmendorf Tearing Tester:

    – Testing tear resistance of:

    – Textile fabrics (especially woven)

    – Paper and cardboard

    – Plastic films

    – Nonwovens

    – Packaging materials

    Benefits of Digital Elmendorf Tearing Tester:

    1. Accurate Tear Strength Measurement – Provides precise data on tear resistance, critical for quality control and product performance.
    2. Digital Readout – Easy-to-read display gives instant, reliable results without manual calculations.
    3. High Reproducibility – Ensures consistent test outcomes due to controlled tearing angle and speed.

     

    1. Fast Testing Process – Simple loading and quick test cycle increase lab efficiency.
    2. Suitable for Various Materials – Tests a wide range of flexible materials like textiles, paper, plastic, and packaging.
    3. Customizable Range – Use of optional weights extends the test range for low to high tear strength materials.
    4. Low Sample Waste – Requires small fabric or material samples, reducing waste during testing.
    5. Standards Compliance – Meets international testing standards (e.g., ASTM D1424, ISO 13937) for credibility and uniformity.

    Features of Digital Elmendorf Tearing Tester:

    Digital Display – Provides accurate and direct reading of tear strength in grams, mN, or cN. Pendulum Mechanism – Uses a swinging pendulum to simulate tear propagation with consistent force. Adjustable Test Range – Includes interchangeable pendulum weights to test various material strengths.

    1. Precision Sample Clamp – Securely holds samples in place to ensure accurate tear initiation.
    2. Pre-Cutting Blade – Integrated knife creates a precise initial slit in the sample before tearing.
    3. User-Friendly Interface – Simple buttons and screen navigation for ease of operation.
    4. Standard Test Compliance – Compatible with ASTM D1424, ISO 1974, ISO 13937, and other tear strength standards.
    1. Sturdy Construction – Made with durable materials for long-lasting performance and stable operation.
    2. Compact Design – Space-efficient footprint ideal for laboratory environments.
    3. Data Output Options- Some models offer USB or printer connectivity for result documentation.

    How to Use a Digital Elmendorf Tearing Tester:

    1. Prepare the Sample – Cut the material (fabric, paper, film, etc.) to standard size (typically 100 × 63 mm for textiles) and slit it with the pre-cutter as required.
    2. Select Pendulum Weight – Choose the appropriate pendulum or add counterweights based on expected tear strength.
    1. Calibrate the Machine – Set the pendulum to its starting position and zero the display.
    2. Clamp the Sample – Fix one half of the sample in the stationary clamp and the other in the moving clamp.
    3. Cut the Initial Slit – Use the integrated blade to make a precise cut at the marked slit area (usually 20 mm).
    1. Release the Pendulum – Trigger the pendulum to swing and tear the sample through the pre-slit.
    2. Read the Result – The digital display will show the tearing force automatically (in g, mN, or cN).
    3. Record or Export Data – Save or print the result if your model supports USB or printer connection.
    4. Reset for Next Test – Reposition the pendulum and prepare a new sample for the next cycle.

    Safety Tip: – Always ensure your hands are clear before releasing the pendulum.

      Fastness Rotary Friction Tester

        A Fastness Rotary Friction Tester, also known as a Rotary Crock meter, is a specialized instrument used to evaluate the color fastness of textiles and materials when subjected to rotational rubbing. This test simulates the wear and friction that fabrics experience during use, helping manufacturers assess the durability of dyes and finishes. Purpose of Fastness Rotary Friction Tester The primary function of the Fastness Rotary Friction Tester is to determine how well a fabric's color withstands rubbing, both in dry and wet conditions. This is crucial for ensuring the longevity and appearance of textiles in real-world applications, such as clothing, upholstery, and footwear.   Working Principle of Fastness Rotary Friction Tester The tester operates by applying a specified pressure to a fabric sample using a standardized rubbing finger covered with a test cloth. The rubbing finger performs a set number of rotational movements (typically 1.125 turns clockwise followed by 1.125 turns counterclockwise) over the fabric surface. After the test, the degree of color transfer to the test cloth and any changes in the fabric's appearance are evaluated against standardized gray scales.   Common Testing Standards - AATCC 116: Colorfastness to Crocking: Rotary Vertical Crock meter Method. ISO 105 X16: Textiles—Tests for color fastness—Part X16: Color fastness to rubbing—small areas. - SATRA TM8: Color fastness to rubbing.   Key Specifications of Fastness Rotary Friction Tester - Rubbing Head Diameter: Typically 16 mm. - Applied Pressure: Approximately 1134 grams (11.1 N). - Rotation: 1.125 turns clockwise followed by 1.125 turns counterclockwise. - Sample Size: Commonly 60 mm × 60 mm. - Test Cloth: Standardized white cotton cloth, either dry or wetted depending on the test condition.   Benefits of Fastness Rotary Friction Tester - Realistic Simulation: Mimics the actual wear and friction fabrics undergo during use. - Versatility: Applicable to a wide range of materials, including textiles, leather, and printed fabrics. - Quality Assurance: Ensures products meet industry standards for color durability. - Standard Compliance: Aligns with international testing standards, facilitating global trade and quality benchmarks.   Applications Fastness Rotary Friction Tester - Textile Industry: Assessing the color durability of garments, upholstery, and other fabric products. - Footwear Manufacturing: Testing the colorfastness of shoe uppers and linings. - Automotive Interiors: Evaluating the wear resistance of seat covers and other interior fabrics. Quality Control Laboratories: Routine testing to ensure product consistency and compliance with standards.   Benefits of Fastness Rotary Friction Tester:
