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   Benefits :
  1. Standardized Evaluation - Provides a consistent and objective way to assess color change or staining.
  2. Simple and Quick to Use - Enables rapid visual comparison during fabric testing.
  3. Widely Accepted - Complies with international standards (ISO, AATCC) for color fastness grading.
  4. Cost-Effective Tool - Inexpensive yet essential for reliable quality control in textiles.

  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).

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.
