An overview of test methods for Martindale abrasion resistance of textiles

The Martindale textile abrasion resistance test occupies an important position in testing the abrasion resistance of textiles. Standard Group (Hong Kong) Co., Ltd. will briefly explain the comprehensive method of the Martindale wear test.

Determination of sample breakage

This method is suitable for all textile materials, but not for fabrics with a short lifespan.

1. The choice of the abrasive.

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 weefs should contain all the characteristic parts of a complete weave. If a complete weave or pattern is large, each part can be sampled separately.

3. Selection of example 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 needed, the unit area of ​​the sample is <500g/m2, and the sample holder Add foam pads and replace the foam pads for each test.

4. Selection of the total effective mass of frictional load.

The total effective mass of the frictional 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 kinds of total effective mass of the corresponding friction load according to the characteristics of the fabric: 1) (795 ± 7) g: suitable for workwear, upholstery fabrics, bed linen products and industrial fabrics; 2) (595±7) g: suitable for clothing and home textiles (furniture upholstery, bed linen products), non-clothing coated fabrics; 3) (198±2) g : coated fabrics suitable for clothing.

5. Abrasive replacement cycle

Wool standard cloth: 50000 times, standard water sandpaper: 6000 times.

6. Inspection interval

Determine in advance the number of rubs when the sample is damaged. Based on this, a suitable inspection interval is designed as an observation point for the wear condition of the sample surface during the sample wear resistance test, and the inspection interval is a certain number of friction times.

7. Show Determination Results

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 meals of the resistance.

8. Determination of mass loss

Applicable to all textile materials, but not suitable for short-life fabrics. The selection of abrasives, sampling method, selection of sample attachment liner, selection of total effective mass of friction load, and abrasive replacement cycle for the determination are consistent with the sample damage method and will not be repeated here.
