What to do before the Martindale Abrasion And Pilling Tester test?

Martindale Abrasion And Pilling Tester can be used to determine the resistance to pilling and other changes in the surface of textiles and is suitable for all textiles, especially for woven fabrics. This test method is not applicable to fabrics with a thickness of more than 3 mm. In addition, Martindale flat abrasion test needs to do the relevant preparatory work before the experiment, in order to more accurately carry out the experiment to obtain the relevant results, technical engineers summarized as follows.

Experimental sampling.

1, initial sampling: generally selected from the rolled fabric samples.

2、Laboratory sampling: take a whole cloth sample from the rolled sample, pay attention to the need to first discard the outer 1 yard of cloth first.


Test samples.

Selection, quantity and preparation

1、In addition to other instructions, before cutting the test sample should be pre-washed or dry-cleaned, according to the end use of the fabric to adjust the moisture, the specific can also be negotiated by both sides.

2, from each laboratory to cut a pair of round specimens, respectively, 38mm and 140mm in diameter.

3, laboratory samples of the whole sample, for clothing can be sampled along different cut pieces, sampling should be staggered sampling, so that the samples taken will not have the same warp and weft. Sampling should avoid wrinkling or other deformation, in addition to other provisions, the cut sample can not be close to the edge of the cloth within 1/10 sampling.

Experimental moisture conditioning.

The specimen should be humidified for at least 4 hours in a standard environment with a temperature of 21±1℃ and a relative humidity of 65±2%.

QINSUN instrument R & D engineer said, clothing wear surface hair pilling or other appearance changes, such as pile, can be simulated by the experimental instrument to determine, the test sample is clamped on the Martindale wear tester, the front of the specimen and another piece of fabric in accordance with a certain geometry of mutual friction, the graph for the beginning of a straight line, and then down gradually become oval, and then in the original straight line The friction should be carried out under a gentle pressure until it reaches the required number of laps. After this action, under standard visual conditions, the degree of pilling and other changes in appearance are generally checked by comparing the standard picture with the original cloth. The ability to resist pilling is generally reported in terms of grade.
