Application
The VIT 418 Washing Fastness Tester (Launderometer) evaluates the color fastness of textiles to washing and dry cleaning, adhering to ISO, BSI, AATCC, and Marks & Spencer standards. It ensures consistent and reliable testing of fabric color durability under various conditions.
The tester features a stainless steel rotor that holds washpots on each of its four sides, rotating at a constant speed of 40 rpm (±2 rpm). Washpots are preheated in the appropriate test solution to simulate real washing conditions.
Equipped with two independent baths, the VIT 418 offers a combined capacity of 12 ISO washpots and 6 AATCC washpots. Each bath has separate controls and drive systems, enabling simultaneous, independent operation. The unit includes features like an opening door and a test-finished alarm for user convenience.
Test Procedure
Test Procedure
- Set the working temperature and time according to standard requirements.
- Add the detergent solution and steel balls to the washpots as specified.
- Place an equal number of washpots on each side of the rotor. Start the motor and run for at least 2 minutes to preheat.
- After preheating, insert prepared fabric samples into the washpots and securely clamp the lids.
- Start the machine and run at 40 rpm for the designated duration.
- Once the cycle completes, rinse the samples with distilled or ionic water. Extract excess moisture using a centrifuge and dry the samples using an appropriate method.
- Evaluate the samples against the standard sample for colorfastness performance.
Importance of Color Fastness Testing
Color fastness testing is crucial for textile quality and safety. Poor colorfastness can result in dye transfer during washing or wear, leading to staining of other fabrics and potential skin irritation due to chemical exposure. This makes proper testing essential for ensuring the durability and safety of textile products.
