1. Scope of application:

Martindale Abrasion Tester is suitable for testing the abrasion resistance of woven fabrics, knitted fabrics, non-woven fabrics, decorative materials, coated fabrics, etc. and the apparent pilling performance test.

2. Complies with the standard:

(1) International standard:

ISO 5470: Rubber or plastic coated fabric - Determination of abrasion resistance

ISO12945.2: Determination of fabric pilling by the Martindale method

ISO12947: Determination of fabric abrasion resistance using the Martindale method for textiles

(2) American Society for Testing Materials:

ASTM?D4966 Fabric Abrasion Resistance Test Martindale Abrasion Tester

ASTM D4970 Test on Abrasion Resistance of Textile Martindale Method

(3) Chinese National Standard:

GB/T 4802.2: Determination of Textile Fabric Lifting of Pilling Performance

GB/T21196: Determination of Abrasion Resistance of Martindale- textile fabrics (Martindale abrasion tester, determination of sample breakage, determinationof mass loss, evaluation of appearance change)

GB/T13775: Abrasion Test of Cotton, Linen, Spun Silk Woven Fabrics

(4 ) EU Standard:

EN?ISO?12947 Textile Martindale Method for the determination of the abrasion resistance of fabrics

(5) British Standards Institute

BS?ISO12947 Textile determination of the abrasion resistance of fabrics by Martindale Method etc.

Third, working principle :

The tissue to be tested is mounted in the upper sample holder and rubbed against abrasives mounted on the grinding table. The friction trajectory is a Lissajous figure. After the specified friction phase according to the test requirements, remove the fabric and calculate the abrasion resistance index or evaluate the fuzzing and pilling level of the sample through visual description.

Four, technical features and technical parameters:

(1) Number of stations: 9;

(2) Counting range: 0-999999 times

(3 ) Maximum stroke : horizontal 60.5 ±0.5 mm, vertical 24 ± 0.5 mm

(4) Mass of material under pressure: gripper: 200 ± 1 g, clothing sample weight: 395 ± 2 g, furniture decoration test Hammer sample weight: 594 ± 2 g, stainless steel disc: 260 ± 1 g.

(5) Effective friction diameter of grinding block:

A type 200g (1.96N) friction head (9KPa)¢28.8-0.084mm

B type 155g (1.52N) friction head (12 KPa ¢90- 0.1mm

(6) Relative moving speed between holder and grinding table: 20-70r/min (adjustable)

(7) Weight of sample loading hammer: 2385±10g

5. Instrument configuration and consumables:

(1) 9 sets of sample holders

(2) 9 pieces of 9 KPa and 12 KPa weights each

(3) each set of Ø38mm and Ø140mm samplers

(4 ) 38mm, 140mm sampler backplate, each piece

(5) A set of pilling test kits

(6) A set of SM50 standard samples

(7) EMPA A set of standard pilling pictures and one piece of SM-25 standard abrasive cloth 1.6m*5m

(8) A set of standard foam 1.5m*0.5m (4 pcs/set)

(9) Standard felt One piece of suede

(10) 20 pieces of 90 mm felt discs

(11) 50 pieces each of 38 mm and 140 mm sampler blades

(12) Other necessary items recommended by the manufacturer's appendix.
