When selecting an instrument for fabric pilling and fluffing testing, there are a few key factors to consider:
1. Test Standard: The first consideration is the test standard or protocol that needs to be followed. Different test standards may require different instruments or testing methods. For example, the ASTM D3512 standard for pilling resistance of textile fabrics specifies the use of a Random Tumble Pilling Tester, while the ASTM D4970 standard for surface fuzzing and pilling of textiles specifies the use of a Martindale Abrasion and Pilling Tester.
2. Sample Size: The size and shape of the samples being tested is also an important factor. Some instruments may be better suited for testing large or irregularly shaped samples, while others may be better suited for smaller or more standard-sized samples.
3. Material Type: The type of material being tested is another important consideration. Some instruments may be better suited for testing specific types of materials, such as synthetic fibers, while others may be better suited for natural fibers.
4. Testing Conditions: The testing conditions, such as the speed, duration, and temperature of the test, should also be considered. Some instruments may offer more flexibility in adjusting these parameters than others.
5. Budget: Finally, cost is also an important consideration. Different instruments may vary significantly in price, and it is important to choose an instrument that meets the testing requirements while also fitting within the available budget.
Some common fabric pilling and fluffing testing instruments include:
1. Random Tumble Pilling Tester: This instrument is designed to test the pilling resistance of textile fabrics by tumbling samples in a machine with abrasive elements.
2. Martindale Abrasion and Pilling Tester: This instrument is designed to test the abrasion and pilling resistance of textile fabrics using a rubbing motion.
3. Electronic Crockmeter: This instrument is designed to test the colorfastness of textile fabrics to rubbing.
4. Brush or Suede Tester: This instrument is designed to test the surface fuzzing and pilling of textile fabrics by rubbing the fabric with a brush or suede material.
Overall, when choosing a fabric pilling and fluffing testing instrument, it is important to carefully consider the test requirements, sample size and material type, testing conditions, and budget. Consulting with instrument manufacturers and testing experts can also be helpful in selecting the most appropriate instrument for a given application.
