Experimental sample preparation method for Martindale textile abrasion test

Author:QINSUN Released in:2023-03 Click:102

Martindale Abrasion Tester is often used in abrasion testing experiments for textiles and leather. Since fabric and leather products inevitably cause friction loss and damage during the use process, as a manufacturer it is necessary to know the service life and service life. of friction resistance, the Martindale Abrasion Tester can solve this problem very well. The Martindale Abrasion Tester simulates the commonly used experimental friction friction method to detect the friction resistance properties of the fabric.

For the Martindale Abrasion Tester in Textile Friction Test, the specific experimental method is explained in detail in \"Martindale Abrasion Tester Experimental Test Method\", if you don\'t know the details. works according to the instructions or the standard requirements.Here the Standard Group (Hong Kong) Co., Ltd. analyzes. the experimental production process of the textile abrasion test.

1. The choice of the shedremedy.

Choose different standard abrasives according to the characteristics of the sample. Non-coated fabric: woven woolen fabric, coated fabric: No. 600 water sandpaper. The abrasive material and the grinding table are separated by wool felt. After the test, check the surface of the felt. If there are stains or wear, it should be replaced in time.

2. Sampling method.

At least 3 pieces, the woven fabric must contain different warp and weft yarns. Jacquard fabric or fancy weave should contain all the signature parts of a complete weave. If a complete weave or pattern is large, each part can be sampled individually.

3. Selection of sample fixture liner.

Determination of the mass per unit area of ​​the sample, the unit area of ​​the sample is ≥500g/m2, no foam pad is required, the unit area of ​​the sample is <500g /m2 , and foam plastic is installedin the sample holder Pads, the foam pads were replaced before each trial.

4. Selection of total effective mass friction load.

The total effective mass of the friction load includes the mass of the container, the stainless steel disc and the weight of the sample. According to the technical parameters of the Atlas M235 Martindale Abrasion Resistance and Pilling Tester, the mass of the container: (200 ± 1) g; the mass of the stainless steel disc: (260 ± 1) g; the mass of the sample weight : (395±2)g, (594±2)g.
According to the purpose of the sample, there are three choices for the total effective mass of the corresponding friction load according to the characteristics of the fabric: 1) (795±7) g: suitable for workwear, furniture upholstery fabrics, bed linen products, industrial tissues; (595 ±7) g: 2) Coated fabrics suitable for clothing and home textiles (upholstery, bedding products); (198±2) g: 3) Coated fabrics suitable for clothing.

5. Abrasive replacement cycle
Wool standard cloth: 50,000 times, standard water abrasive paper: 6,000 times.

6. Inspection Interval
For the friction when the sample is damaged. Estimate the number of rubs and design a suitable inspection interval based on this as an observation point for the wear condition of the sample surface during the sample\'s wear resistance test. The inspection interval is a certain number of rubbing times.

7. Measurement result display
Measure the total number of rubs when each sample is damaged and use the accumulated number of rubs before the sample is damaged as the number of abrasions.
