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.

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 e3512 more periods during the test. Store the fabric rating standards and handle them under conditions that will preserve their original form and appearance.

OEM is also acceptable for us.

ASTM D3512 Random tumble pilling tester-fabric propensity to pilling

To offer d3521 strongest sales and after-sale services, we are looking for additional motivated individuals to join our team. Laboratory standard compressed air supply required.

The procedure is generally applicable to all types of woven and knitted apparel fabrics. 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 d512 alarm. Current edition approved Dec. 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.

Allow the chamber to dry before aatm next use.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. This experience should be borne in mind when adopting levels of acceptability for any series of standards. Cotton sliver is available commercially. 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.


Not exactly what you want? The development of pills may be accompanied by other surface phenomena such as loss of cover, color change, or the development of fuzz. The observed resistance to pilling is reported using an arbitrary rating scale.

Since the overall acceptability of a specific fabric is dependent on both the characteristics of the pills and the other factors affecting surface appearance, it is suggested that fabrics tested in the laboratory be evaluated subjectively with regard to their acceptability and not rated solely on the number of pills developed. 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. 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.

Vacuum all specimens in this manner. To form pills with appearance and structure that resemble those produced in actual wear, small amounts of short-length gray cotton? Originally approved in 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. Vacuum-clean the test chamber. We have many experienced agents who work in consulting, sales and after-sale services in many industrial countries and regions in the world.

A number in parentheses indicates the year of last reapproval.

China tester tool China a. The pilling resistance of a specific fabric in actual wear varies more with general conditions of use and individual wearers than in replicate fabric d35512 subjected to controlled laboratory tests.


Pilling Resistance Testing of Textile Fabrics Using ASTM and AATCC

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. Record on the data sheet any hang-ups or other abnormal behavior of the specimens.

Add another 25 ast see Note 6 of 6-mm 0. If a specimen wedges around the impeller without tumbling or lies d33512 on the bottom or side of the chamber, shut off the air, stop the machine, remove the face plate, and free the specimen. In some cases the purchaser and the supplier may have to test a commercial shipment of one or more specific materials by d512 best available test method, even though the test method is not recommended for acceptance testing.

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. Compressed air is also injected into the chamber to assist in the tumbling action. The astj resistance to pilling is reported on an arbitrary scale ranging from 5 no pilling to 1 very severe pilling.

Testing before refurbishing may be adviseable.

Other materials with established test values may be used for this purpose. Firmly grasp the specimen by a corner and allow the vacuum suction to draw the specimen inside. Shipped in 15 days after payment.
