    Gray Scale

     

    The Gray Scale is a visual tool used in the textile and dyeing industry to evaluate and grade the color change or staining of a fabric after testing (e.g., washing, rubbing, and light exposure). It helps assess how much a fabric’s color has altered or transferred during durability or fastness tests.

    Types of Gray Scale:

    1. Gray Scale for Color Change – Compares the original and tested sample to measure color fading or alteration.
    2. Gray Scale for Staining – Compares a white adjacent fabric (before and after testing) to assess color transfer or staining.

    Rating System :

    – Uses a 1 to 5 scale:

    – Grade 5: No change or staining (excellent)

    – Grade 1: Severe change or heavy staining (poor)

    Intermediate grades (like 4–5, 3–4, etc.) are also used for finer evaluation.

     

    Construction :- Each scale includes pairs of gray chips with varying contrast levels to visually match the test results.

    Usage Areas:- Textile testing labs- Dyeing and finishing quality control- Standards like ISO, AATCC, and BIS tests

    3. Easy Visual Comparison – Designed for quick side-by-side assessment of fabric before and after testing.

     

    How to Use :

    Select the Right Gray Scale – Use Color Change scale to check fading, or staining scale to check color transfer.

    1. Place the Samples – Lay the untested (original) and tested fabric side by side (for color change)

    – Or place the adjacent white fabric next to the gray scale (for staining).

    1. Match Against Gray Scale Chips – Visually compare the difference between the samples and find the closest matching gray pair on the scale.

     

    1. Assign a Grade

    – Grade from 1 to 5, where:

    – Grade 5 = no change/staining

    – Grade 1 = severe change/staining

    – Use half-grades like 4–5 if needed.

    1. Record the Result – Note the grade in your test report as per the test method (e.g., ISO 105).
    2. Store Properly – Keep the gray scale away from light and moisture to avoid fading.
    3. Features :
      1. Dual Type Availability – Comes in two types: for Color Change and for Staining.
      2. 5-Point Grading System – Grades from 1 (poor) to 5 (excellent), with half-step intervals like 4–5, 3–4.
      3. Standardized Grey Chips – Includes contrasting grey color pairs to match fabric changes accurately.
      4. Compact Design – Small, portable card or booklet format for easy lab and field use.

     

    Categories:

    1. Gray Scale for Color Change – Used to evaluate the degree of color fading or change in a fabric after testing (e.g., washing, light exposure). – Assesses how much the original color has altered.
    2. Gray Scale for Staining – Used to assess the degree of color transfer from a dyed fabric to an adjacent white fabric during testing (e.g., rubbing, washing).

    – Evaluates staining on undyed fabrics.

     

    These two types are essential tools in color fastness testing across textile labs. Want to know which standard tests use each type?

    2. Weigh the Sample - Place the cut sample on a precision balance or GSM scale to determine weight.
    3. Calculate GSM - Multiply the sample weight (in grams) by 100 to get GSM.
      GSM Formula (Grams per Square Meter): GSM is used to measure the weight of fabric and indicates its thickness and quality. Formula: GSM = (Sample Weight in grams × 10000) / Sample Area in cm² For standard cutters that cut 100 cm² samples: GSM = Sample Weight (in grams) × 100   Example: - If a 100 cm² fabric sample weighs 1.5 grams: GSM = 1.5 × 100 = 150 GSM

    GSM Cutter with Balance

      A GSM Cutter with Balance is a lab toolset used to determine the GSM (Grams per Square Meter) of fabrics, which indicates the fabric's weight and density. The kit includes a GSM round cutter and a precision weighing balance.   Purpose GSM Cutter with Balance: To accurately measure the weight per unit area of textile, paper, or nonwoven samples for quality control and product classification.   How It Works: GSM Cutter: - A circular blade cuts a fixed area (usually 100 cm²) from the fabric. Weighing Balance: - The cut piece is weighed, and the result is multiplied by 100 to get GSM. GSM = Weight (in grams) × 100   Applications of GSM Cutter with Balance: Textile and garment industry Nonwovens and paper manufacturing QC labs and R&D   Benefits of GSM Cutter with Balance: Accurate GSM Measurement - Ensures precise fabric weight analysis for quality control. Quick and Simple Operation - Allows fast sampling and GSM calculation in minutes. No Need for Area Calculation - Cutter gives a fixed area (usually 100 cm²), simplifying the formula. Improves Product Consistency - Helps maintain uniform fabric weight across batches.   Portable and User-Friendly - Compact design makes it ideal for labs and production floors. Cost-Effective Tool - Offers high accuracy without the need for expensive equipment. Versatile Use - Suitable for fabrics, paper, leather, films, and more.   Features of GSM Cutter with Balance: Rotary Blade Cutter - Stainless steel blades for clean and accurate circular cuts. Fixed Sample Area - Typically 100 cm², eliminating the need for area measurement. Precision Digital Balance   - Measures in grams with high resolution (0.01 g or better).   Rubber Cutting Pad - Protects blade and provides a smooth surface for cutting. Safety Lock - Prevents accidental blade exposure. Compact & Durable Design- Long-lasting, lab-friendly construction.   How to Use GSM Cutter with Balance: Prepare the Fabric Sample- Place the fabric on the rubber cutting pad. Cut the Sample - Hold the GSM cutter firmly and rotate it to cut a 100 cm² circular sample. Turn on the Balance - Power up the digital weighing scale and tare it to zero.   Weigh the Sample - Place the cut fabric piece on the balance and note the weight in grams. Calculate GSM - Multiply the weight by 100 to get GSM.  - GSM = Sample weight (g) × 100 Record the Result- Log the GSM value for quality control or analysis. Clean and Store - Wipe the cutter and balance, and store them safely after use.   GSM Calculation Formula: GSM (g/m²) = (Weight of Sample in grams) × 100 When using a GSM cutter (100 cm²): The cutter gives a fixed area of 100 cm², which is 1/100th of a square meter. So, multiplying the sample's weight by 100 gives the GSM directly. Example: If the sample weighs 1.75 g, then: GSM = 1.75 × 100 = 175 g/m²   Balance Calibration Guide (Manual Calibration): Warm-Up   - Turn on the balance and let it warm up for 10–15 minutes if required. Level the Balance   - Use the built-in bubble level and adjust leveling feet until the bubble is centered. Tare the Balance   - Press the “TARE” or “ZERO” button to reset the display to 0.000 g.   Enter Calibration Mode   - Press the “CAL” or “MODE” button (depends on the model). - Some balances may require holding the button for a few seconds. Use Standard Weight   - When prompted, place a certified calibration weight (e.g., 100g, 200g) on the pan.   - Wait for the display to stabilize.   Confirm Calibration   - The balance will beep or show “PASS” once successful.   - Remove the weight when done. Recheck Zero  - Ensure the display returns to 0.000 g after removing the weight.   Tips: Use certified weights for accuracy (Class F1 or E2). Calibrate in a draft-free, vibration-free environment. Calibrate daily or before critical measurements.     GSM Cutter  & Balance GSM Cutter Brand: Schroder Origin: Germany Capacity: 100 Sq.cm Supplied with 1 pcs cutting Pad and 04 pcs cutting blade.
