ASTM D3512 Random tumble pilling tester-fabric propensity to pilling

This experience should be borne in mind when adopting levels of acceptability for any series of standards. The development of pills may be accompanied by other surface phenomena such as loss of cover, color change, or the development of fuzz.

If a 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.

ASTM D3512 Textile Random Tumble Pilling Tester

NOTE 2—An adequate speci? The procedure is generally applicable to all types of woven and knitted apparel fabrics. The observed resistance to pilling is reported using an arbitrary rating scale.

Apparatus and options for astmm evaluation are listed in Table 1. The rounded end of a glass stirring rod works well, also, but caution should be used to prevent breakage and possible injury from broken glass.


China bert tester China main tester China benz tester. The original surface of the liner, produced by slicing the material, should be used without any further treatment such as sanding.

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. This test method has no known bias. To eliminate any tendency for the liner to rotate, tape the outside edge of the liner to the chamber wall at the butt joint with a short piece of mm 1-in. Within the text, the inch-pound units are shown in parentheses.

Record on the data sheet any hang-ups or other abnormal behavior of the specimens. To offer the strongest sales and after-sale services, we are looking for additional motivated individuals to join our team. 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.

Current edition approved Dec. Allow the chamber to dry before the next use. Apparatus and Materials 6.

The side against the chamber may or may not have been used. For fabric components of fabricated systems use the entire system. What is our Random Tumble Pilling Tester used for? Preparation of Apparatus Laboratory standard compressed air supply required. Discard these and repeat the astj with new specimens.


Pilling Resistance Testing of Textile Fabrics Using ASTM and AATCC

Firmly grasp the specimen by a corner and allow the vacuum suction to draw the specimen inside. Random Tumble Pilling Tester1 This standard is issued under the? Ply-wooden cases, inner plastic films wrapped, Sometimes we use wooden case, sometimes we use carton case.

Cotton sliver is available commercially. NOTE 3—Full-strength adhesive or any dilution down to 1 part adhesive with 1 part water may be used see 7. Selection, Number, and Preparation 9.

Specimens should be staggered in such a manner that no two specimens contain the same yarns. Compare data from each shipment to avert problems. 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 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.

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.
