Pilling Resistance Testing of Textile Fabrics Using ASTM and AATCC
If the pills are concentrated in any one strip in either fabric direction, or in any one portion zstm a specimen, report this condition. OEM is also acceptable for us. 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.
Compressed air is also injected into the chamber to assist in the tumbling action. To offer the strongest sales and after-sale services, we are looking for additional motivated individuals to join our team. These factors are not evaluated when pilling is rated solely on the number of pills. Each test facility must decide on an appropriate fabric.
No universal standard fabric is available. This experience should be borne in mind when adopting levels of acceptability for any series of standards. 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.
The development of pills may be accompanied by other surface phenomena such as loss of cover, color change, or the development of fuzz. 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.
We have many experienced agents who work in consulting, sales and after-sale services in many industrial countries and regions in the world. Apparatus and options for visual evaluation are listed in Table 1.
ASTM D3512 Textile Random Tumble Pilling Tester
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. This experience should be borne in mind when adopting levels of acceptability for any series of standards. After each test, clean the bottom of the weight by wiping with a cloth wetted in a solution of detergent and water. A number in parentheses indicates the year of last reapproval.
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. Random Tumble Pilling Tester. 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.
NOTE 5—If there is not sufficient material to provide three standard-size specimens, run with the available number of specimens rather than adding a specimen from another fabric, since there may be a strong interaction between fabrics which will create misleading results.
Combining values from the two systems may result in nonconformance with the speci? Originally approved in These factors are not evaluated when pilling is rated solely on the number of pills. Strips indicate that different yarns may have been used in making the fabric being tested. This test method has no known bias. 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.
The observed resistance to pilling is reported using an arbitrary rating scale. Selection, Number, and Preparation 9. Testing atm refurbishing may be adviseable. It is advisable to have a separate set of in-house fabric rating standards for each surface effect to be rated. Link to Active This link will always route to the current Active version of the standard.
NOTE 4—Although v3512 use of glued or not glued specimens is acceptable, the measurements should not be compared. Textile Random Tumble Pilling Tester. Referenced Documents aastm separately The documents listed below are referenced within the subject standard but are asym provided as part of the standard. Apparatus and Materials 6. China home tester China bill tester China unit tester. 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.
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. 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. If it is used for acceptance testing, it should be used with caution because the between-laboratory precision is poor.
Store liners in original packaging in a cool, dry place. Contact Supplier Start Order. Vacuum-clean the test chamber.
Precision and Bias Random Tumble Pilling Tester1 This standard is issued under the? Testing before refurbishing may be adviseable. If a specimen wedges around the impeller without tumbling or lies inert on the bottom or side of f3512 chamber, shut off the air, stop the machine, remove the face plate, and free the specimen.
Repeat, holding an adjacent corner. The side against the chamber may or may not have f3512 used. If you would like to buy machines from our agents directly, kindly visit our company website find the agents contact or you can leave a message by alibaba.
Laboratory standard compressed air supply required. 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.
Other materials with established test values may be used for this purpose.
