The development of pills dd3512 be accompanied by other surface phenomena such as loss of cover, color change, or the development of fuzz. The observed resistance to pilling ast, reported using an arbitrary rating scale.

Pressing the adhesive into the specimen face may be accomplished using the dispensing nozzle in a closed con? After each test, clean the bottom of the weight by wiping with a cloth wetted in a solution of detergent and water.

Combining values from the two systems may result in nonconformance with the speci?

Pilling Resistance Testing of Textile Fabrics Using ASTM and AATCC

Cotton sliver is available commercially. This experience should be d35112 in mind when adopting levels of acceptability for any series of standards.

Since the overall acceptability of a ast 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.

The test results from the two laboratories should be compared using a statistical test for unpaired data, at a probability level chosen prior to c3512 testing series. 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. 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.


Pilling Resistance of Textile Fabrics

For fabric components of fabricated systems use the entire system. Combining values from the two systems may result in non-conformance with the standard. Testing before refurbishing may be adviseable. 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 fabrics.

NOTE 4—Although the use of glued or not glued specimens is acceptable, the measurements should not be compared. China bert tester China main tester China benz tester. Hang the specimens on racks until dry, and in any case for at least 2 h. Laboratory standard compressed air supply required.

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.

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.

Not exactly what you want? NOTE 6—The mass of a 6-mm long section of tex sliver is about 25 mg.

If a specimen wedges around the impeller without tumbling or lies inert on the bottom or side of the xstm, shut off the air, stop the machine, remove the face plate, and free the specimen. 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.

xstm Add another 25 mg see Note 6 of 6-mm 0. Precision and Bias Take the specimens evenly spaced across the width of the laboratory sample or from three different panels in a garment. To determine the pilling and fuzzing characteristics of textile aetm.

Random Tumble Pilling Tester1 This standard is issued under the? Testing before refurbishing may be adviseable. 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 e3512 for counting, sizing, and calculating.

Record on the astk sheet any hang-ups or other abnormal behavior of the specimens. It is advisable to have a separate set of in-house fabric rating standards for each surface effect to be rated. Random Tumble Pilling 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 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.

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 side against the chamber d35512 or may not have been used. Selection, Number, and Preparation 9.
