Always use the same weight and plane angle. We have many experienced agents who work in consulting, sales and after-sale services in many industrial countries and regions in the world.
Pilling Resistance Testing of Textile Fabrics Using ASTM and AATCC
After each test, clean the bottom of the weight by wiping with a cloth wetted in a solution of detergent and water. If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. The visual standards are most advantageous when the laboratory test specimens correlate closely in appearance with worn fabrics and show a similar ratio of pills to fuzz.
Apparatus and options for visual evaluation are listed in Table 1. The degree of fabric pilling is evaluated by comparison of the tested specimens with visual standards that may be actual fabrics, or photographs of fabrics, showing a range of pilling resistance.
The pilling resistance of a specific fabric in actual wear varies more with general conditions of use and individual wearers than in replicate fabric specimens subjected to controlled laboratory tests. Not exactly what you want?
Discard these and repeat the test with new specimens. Tests run with one or two specimens, while not strictly comparable with standard tests, are considered more indicative than tests that include more than one fabric type. The pilling resistance of a speci? Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
Random Tumble Pilling Tester uses stainless steel impellers rotate within individually lit aluminium chambers constantly tumbling test fabrics against cork liners for a pre-determined time controlled by a timer and audible alarm. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Firmly grasp the specimen by a corner and allow the vacuum suction to draw the specimen inside. For fabric components of fabricated systems use the entire system. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm.
Vacuum all specimens in this manner. These factors are not evaluated when pilling is rated solely on the d351 of pills. Preparation of Apparatus Record on the data sheet any hang-ups or other abnormal behavior of the specimens.
OEM is also acceptable for us. Apparatus and Materials 6. Cotton sliver is available commercially.
Pilling Resistance of Textile Fabrics
Store the fabric rating standards and handle them under conditions that will preserve their original form and appearance. The original surface of the liner, produced d352 slicing the material, should be used without any further treatment such as sanding.
The test results showed that those fabrics with average ratings less than or equal to 2. Clean around the shaft of the impeller using a sharp instrument, such as a pick needle, to remove trapped detritus.
Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. Each test facility must decide on an appropriate fabric. Other materials with established test values may be used for this purpose. As a minimum, the test samples should be used that are as homogeneous as possible, drawn from the material from which the disparate test results were obtained, and randomly assigned in equal numbers to each laboratory for testing.
Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. Compare data from each shipment to avert problems. Pressing the adhesive into the specimen face may be accomplished using the dispensing nozzle in a closed con?
ASTM D3512 Random tumble pilling tester-fabric propensity to pilling
If the liner being checked has been contaminated, the pilling level on the standard rating fabric will be different than historical results obtained when testing as in Ply-wooden cases, inner plastic films wrapped, Sometimes we use wooden case, sometimes we use carton case.
The observed resistance to pilling is reported on an arbitrary scale ranging from 5 no pilling to 1 very severe pilling. The test results from the two laboratories should be compared using a statistical test for unpaired data, at a probability d35112 chosen prior to the testing series. Random Tumble Pilling Tester.
