Spray Rating Tester
Spray Rating Tester
The Spray Rating Tester is a textile testing instrument used to evaluate the water resistance or water repellency of fabric surfaces. It measures how well a fabric can resist wetting when exposed to a controlled spray of water, helping assess its performance in rain or damp conditions.
Purpose of Spray Rating Tester
– To assess surface wetting resistance of textiles.
– Commonly used for outdoor clothing, rainwear, tents, and performance fabrics.
Working Principle of Spray Rating Tester
– A fabric specimen is mounted at a 45° angle.
– Water is sprayed from a standard nozzle for a specific time.
– After spraying, the fabric is visually rated based on the appearance of water drops and wetting.
Key Components of Spray Rating Tester
– Spray Nozzle: Delivers a consistent, standard water spray.
– Funnel & Reservoir: Controls the flow and volume of water.
– Specimen Holder: Positions the fabric at a 45° angle.
– Spray Stand: Ensures accurate nozzle height and positioning.
Standards Used of Spray Rating Tester
– AATCC 22
– ISO 4920
– BS EN 24920
Applications of Spray Rating Tester
– Rainwear and water-resistant textiles.
– Quality control in fabric finishing.
– R&D for performance apparel.
Benefits of Spray Rating Tester:
- Quick and Simple Evaluation – Offers a fast way to assess fabric water repellency without complex setup.
- Standardized Testing- Complies with AATCC 22 and ISO 4920, ensuring globally accepted results.
- Cost-Effective- Low maintenance and no power requirement make it economical for routine lab use.
- Improves Fabric Performance – Helps manufacturers develop or improve water-resistant textiles.
- Non-Destructive Test – Does not damage the fabric, allowing for additional tests on the same sample.
- Visual Grading- Easy to interpret using a standard spray rating chart (0 to 100 scale).
- Supports Quality Control – Detects finish degradation or variation in water-repellent treatments.
- Portable and Compact- Lightweight design allows easy use in various lab or field settings.
Features of Spray Rating Tester:
- Standardized Spray Nozzle – Delivers consistent water spray per AATCC and ISO specifications.
- 45° Specimen Mounting Angle – Ensures uniform test setup for accurate and repeatable results.
- Stainless Steel or Aluminum Frame – Corrosion-resistant and durable for long-term use with water exposure.
- Water Reservoir and Funnel System – Provides precise water volume (usually 250 ml) for each test.
- Graduated Spray Stand- Fixed height (150 mm above specimen) for controlled spray impact.
- Detachable Specimen Holder- Easy loading and removal of fabric samples.
- Compact and Lightweight Design – Portable and convenient for both lab and field testing.
- No Electricity Required – Fully manual operation increases reliability and reduces operating costs.
How to Use Spray Rating Tester:
- Prepare the Sample – Cut fabric to standard size (usually 180 × 180 mm). – Condition the sample if required (21°C, 65% RH for 24 hours).
- Mount the Fabric – Place the fabric on the specimen holder at a 45° angle.
- Fill the Reservoir – Pour 250 ml of distilled water into the upper funnel.
- Start the Test – Release the water through the nozzle; it sprays over the fabric for about 25–30 seconds.
- Inspect the Fabric – After spraying, visually assess the water beading or penetration on the surface.
- Rate the Sample – Compare the fabric’s wetting pattern with the standard spray rating chart: – 100 = No sticking/wetting – 90–50 = Partial wetting – 0 = Complete wetting
- Record the Rating – Document the spray rating for quality control or reporting.
