Method for determination of pilling properties of clothing fabrics

1. Test Tool:
Martindale Abrasion Tester

2. Test Principle:
Under the specified pressure, the round test piece on the sample holder The sample and the abrasive on the grinding table (the same cloth or woolen abrasive as the tested sample) are rubbed according to the Lissajous curve. The sample is free to rotate about the central axis perpendicular to the sample plane. After the defined rubbing period, the test pieces are assessed for linting and pilling by visual description.

3. Reference standard:
GB/T 4802.2-2008 Determination of the pilling properties of textile fabrics Part 2: Modified Martindale method (GB/T 4802 Fabric pilling) The performance measurement consists of four parts, namely the circular web method, the modified Martindale method, the pilling box method, and the random tumbling method. These four methods are used to test the pilling performance of fabrics. The content of this section is basedon the Martindale Dust Resistance Abrasion Tester , outlining the method of using this instrument to test the pilling performance of fabrics.)

Fourth, a brief introduction to the main equipment of the test:
1. Sample armature: mainly composed of sample armature, test It consists of three parts: the sample armature ring and the sample armature guide shaft. The first two are mainly used when installing the monster.
2. Grinding table: It consists of a pilling table, a clamping ring and a holder for fixing the clamping ring.
3. Auxiliary Device for Sample Installation: The equipment necessary to ensure that the sample in the sample holder does not have any wrinkles during installation.
The upper part is a groove that fits the sample holder. When installing the test sample, first put the sample clamping ring on the auxiliary device for installation, put the felt and sampleon the sample armature and bend it upside down into the groove of the auxiliary device, then place the clamping ring on the auxiliary device. The specimen holder is tightened so that the specimen wraps around the specimen holder. When installing, the sample must be flat and wrinkle-free.
4. Pressurized hammer: Make sure that the abrasive installed on the pilling table has no creases or wrinkles.
5. Sorting box: Use fluorescent tubes or incandescent lamps for illumination to ensure that the sample is evenly lit across the entire width, and care should be taken that the observer is not looking directly into the light. The angle between the illumination device and the sample plate should be kept between 5° and 15°. The distance between the eye with normal corrected vision and the sample should be 30 cm - 50 cm.
