ASTM D Resistance to Pilling. What This Test is Used For: This test is used to cover the resistance to the formation of pills and other related surface. ASTM D/DM Standard Test Method for Pilling Resistance and Other Related Surface Changes of Textile Fabrics: Random. Find the most up-to-date version of ASTM D at Engineering

Historical Version s – view previous versions of standard. 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. The observed resistance to pilling is reported on an arbitrary scale ranging from 5 no pilling to 1 very severe pilling. Discard these and repeat the test with new specimens.

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. The development of pills may be accompanied by other surface phenomena such as loss of cover, color change, or the development of fuzz. 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.

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.

This test method has no known bias. 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. Testing before refurbishing may be adviseable. Preparation of Apparatus If it is used for acceptance testing, it should be used with caution because the between-laboratory precision is poor. Both results should be reported.

China home tester China bill tester China unit tester. If a bias is found, either its cause must be found and corrected, or future test results must be adjusted in consideration of the known bias. The procedure is generally applicable to all types atm woven and knitted apparel fabrics. Users of this standard are expressly advised that determination of the validity of any such patent rights, awtm the risk of infringement of such rights, satm entirely their own responsibility.

Apparatus and options for visual evaluation are listed in Table 1. Take the specimens evenly spaced across the width of the laboratory sample or from three different panels in a garment. The observed resistance to pilling is reported using an arbitrary rating scale. Vacuum-clean the test chamber. The observed resistance to pilling is reported on an arbitrary d35512 ranging from 5 no pilling to 1 very severe pilling.

Your comments asmt invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.

ASTM D3512 Textile Random Tumble Pilling Tester

China tester tool China a. For fabric components of fabricated systems use the entire system. This experience should be borne in mind when adopting levels of acceptability for any series of standards. If it is used for acceptance testing, it should be used with caution because the between-laboratory precision is poor.

Random Tumble Pilling Tester1 This standard is issued under the?

Pilling Resistance Testing of Textile Fabrics Using ASTM and AATCC

Apparatus and Materials 6. It is advisable to have a separate set of in-house fabric rating standards for each surface effect to be rated. To offer the strongest sales and after-sale services, we are looking for additional motivated individuals to join our team. Compressed air is also injected into the chamber to assist in the tumbling action. The development of pills may be accompanied by other surface phenomena such as loss of cover, color change, or the development of fuzz. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

Firmly grasp the specimen by a corner and allow the vacuum suction to draw the specimen inside. Laboratory standard compressed air supply required.

Pills are caused to form on fabric by a random rubbing action produced by tumbling specimens in a cylindrical test chamber lined with a mildly abrasive material. Summary of Test Method 4.

To determine the pilling and fuzzing characteristics of textile fabrics. NOTE 7—Depending on the nature of the material under test, running times of other than 30 min may be more appropriate for evaluating the pilling tendencies of fabrics; for example, min intervals up to 30 min may be more indicative for certain knit or soft-woven d351.

Compare data from each shipment to avert problems. Avoid areas with wrinkles and other distortions. Store liners in original packaging in a cool, dry place. Current edition approved Dec. Link to Active This link will always route to the current Active version of the standard. Ply-wooden cases, inner plastic films wrapped, Sometimes we use wooden case, sometimes we use carton case.

Contact Supplier Start Order. Asrm indicate that different yarns may have been used in making the fabric being tested. A superscript epsilon e indicates an editorial change since the last revision or reapproval.

Pilling Resistance of Textile Fabrics

Pressing the adhesive into the specimen face may be accomplished using the dispensing nozzle in a closed con? We have many experienced agents who work in consulting, sales and after-sale services in many industrial countries and regions in the world.

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. The procedure is generally applicable to all types of woven and knitted apparel fabrics.
