Since the overall acceptability of a speci? Textile Random Tumble Pilling Tester.

To form pills with appearance and structure that resemble those produced in actual wear, small amounts of short-length gray cotton? Pills are caused to form on fabric by a random rubbing action produced by tumbling specimens in a v3512 test chamber lined with a mildly abrasive material.

Pilling Resistance of Textile Fabrics

After each test, clean the bottom of the weight by wiping with a cloth wetted in a solution of detergent and water. It is advisable to have a separate set of in-house fabric rating standards for each surface effect to be rated. Testing before refurbishing may be adviseable. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm.

Last previous edition approved in as D — 05 e1. To determine the pilling and fuzzing characteristics of textile fabrics.

We have many experienced agents who work in consulting, sales and after-sale services in many industrial countries and regions in the world. Preparation of Apparatus Link to Active This link will always route to the current Active version of the standard.

Both results should be reported. If wstm specimen wedges around the impeller without tumbling or lies inert on the bottom or side of the chamber, shut off the air, stop the machine, remove the face plate, and free the specimen.

Firmly grasp the specimen atm a corner and allow the vacuum suction to draw the specimen inside. If any of the specimens show a high concentration of pills in a general line not parallel to either fabric direction, assume a specimen is wedged around the impeller see Note 8 for one or more periods during the astj.

Discard these and repeat the test with new specimens. With 2 or 4 pilling test chambers. Random Tumble Pilling Tester uses stainless steel impellers rotate within individually lit aluminium chambers constantly tumbling test fabrics against cork liners for c3512 pre-determined time controlled by a timer and audible alarm.

Contact Supplier Start Order. These factors are not evaluated when pilling is rated solely on the number of pills. Allow the chamber to dry before the next use. Counting the pills and weighing their number with respect to their size and contrast, as a combined measure of pilling resistance, is not recommended because of the excessive time required for counting, sizing, and calculating.

Apparatus and Materials 6. Vacuum-clean the test chamber. No universal asym fabric is available.

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 d3152 disparate test results were obtained, and randomly assigned in equal numbers to each laboratory for testing. Specimens should be staggered in such a manner that no two specimens contain the same yarns. Astmm cases, inner plastic films wrapped, Sometimes we use wooden case, sometimes we use carton case.

Compare data from each shipment to avert problems. To offer the strongest sales and after-sale services, we are looking for additional motivated individuals to join our team.

Within the text, the inch-pound units are to be regarded as the standard. 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.

Laboratory standard compressed air supply required. 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. NOTE 8—The use of air injection with all fabrics, woven or knitted, has been found to signi? If it is used for acceptance testing, it should asmt used with caution because the between-laboratory precision is poor.

In some cases c3512 purchaser and the supplier may have to test a commercial shipment of one or more specific materials by the best available test method, even though the test method is not recommended for acceptance testing. If you feel that your comments have astmm received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.

Pilling Resistance Testing of Textile Fabrics Using ASTM and AATCC

China bert tester China main tester China benz tester. 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 ASTM D von For fabric components of fabricated systems use the entire system. NOTE 2—An adequate speci? Check, also, when test results appear questionable, or following a change in test equipment such as the use of a new shipment of cork liners.

What is our Random Tumble Pilling Tester used for? The pilling resistance of a speci? To cope with this problem in the laboratory, make a subsequent test using the used liner surface on which the silicone-treated fabric was tested with a standard in-house fabric of known pilling history.

Selection, Number, and Preparation 9. The observed resistance to pilling is reported on an arbitrary scale ranging from 5 no pilling to 1 very severe pilling. A series of standards, based on graduated degrees of surface change of the fabric type being tested, may be set up to provide a basis for subjective ratings.
