Test method for abrasion resistance of textiles

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

(1) Selection of abrasives. 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 must contain all the characteristic parts of a complete weave. If a complete weave or pattern is large, each part can be sampled individually.

(3) Specimen fixture liner selection. Measure the mass per unit area of ​​the sample, the unit area of ​​the sample is ≥500g/m2, no foam plastic liner is needed, the sample area unit is <500 g/m2, and the foam plastic liner is installed in the sample fixture and replaced every time Foam filling.

(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.

Depending on 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 fabric: 50000 times; standard water sandpaper: 6000 times.

(6) Inspection Interval Estimate the number of times friction occurs when the sample is damaged and based on this design a suitable inspection interval to test the wear condition of the sample surface during the wear resistance test of the sample Observation points, the inspection interval is a certain number of friction times.

(7) The measurement result indicates the total number of rubs when each sample is damaged, and the number of rubs accumulated before the sample is damaged is taken as the number of abrasions. The determination of the mass loss is suitable for all textile materials, but not for fabrics with a short life. The selection of abrasives, sampling method,selection of sample attachment liner, selection of the 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. Inspection interval 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 rubs. During the test, check the wear of the sample according to the set inspection interval. When the sample is damaged or reaches the specified number of rubs, the test ends. The measurement of mass loss is divided into two situations: in the first case, each inspection interval the difference Δmi between the mass of the sample before the test and the mass of the test sample after the wear test is measured; in the second case, the sample When the wear point is reached, measure the diffhil Δm between the quality of the sample before the test and the quality of the sample after the wear test.

(2) Test Results

Using the measurement of fabric abrasion resistance - the measurement of mass loss, the test results include the following data: 1) When each inspection interval is reached, the measured 2) the mass loss Δmi of the sample reaches the wear point, that is, the mass loss Δm when the test reaches the end point; 3) the relationship between the mass loss Δmi and the number of frictions; 4) the wear resistance index Ai (times/g), the formula for the calculation is: Ai =N/ΔmiN——is the total number of frictions. Determination of abrasion resistance of fabrics with change in appearance quality - The method of change in appearance quality is suitable for textile fabrics with a short service life. The selection of abrasives, sampling method and filling of the sample confirmation are consistent with the method of measuring the schade of fabric samples and will not be repeated here. The total effective mass of the friction load (198 ± 2) g; abrasive replacement cycle: new foam plastics and standard abrasives are replaced for each test; requirements for the assessment of the appearance of the sample: from the abrasion test to the surface change specified in the agreement, the number of rubs is used as the resistance Measured value of abrasiveness. Design a suitable inspection interval as an observation point for the change in the appearance of the sample. Abrasion test for the number of rubs stipulated in the agreement, and evaluate the surface change of the sample by comparing it with the untested sample of the same fabric. Test Results: Surface changes include discoloration, fuzzing and pilling. If the end point of the wear test is to achieve the surface change specified in the agreement,the inspection agreement shall specify the degree of discoloration, pilling and pilling on the surface of the sample, and the test results shall use the sample to meet the degrees of discoloration, pilling and pilling specified in the inspection agreement, expressed as the number of friction hours. If the end point of the wear test is the number of rubs specified in the agreement, the test result is that after the wear test reaches the specified number of rubs, the sample is compared with the original after the test, and the degree of discoloration, pilling and pilling of the sample after the test has been assessed. The discoloration level, pilling and pilling level of the sample after the test will explain the change in the appearance quality.
