Introduction to fabric and leather pilling and pilling tester

Pilling and pilling tester is a 6-station tester, used to evaluate the anti-wear or pilling effect of fabric (or leather). The sample is typically scrubbed for a set number of cycles with a known abrasive, such as a nylon brush, sponge, or Velcro, and the degree of lint is documented by comparison to an industry testing standard (such as ASTM D3512) or to a laboratory. -developed standard. Save. The machine can be configured with a variety of grinding materials or test materials and test weights.
The pilling and pilling tester is usually used to test the pilling and wear resistance of textiles, so it is also called fabric pilling and pilling tester. According to different pilling methods, it can be divided into the following four types of pilling testersants: rolling box pilling tester, random rotation pilling tester, circular path pilling tester and Martindale mmal wear resistance test.

This article mainly introduces the instrument principles and related standards of these four pilling machines, and analyzes the requirements of different domestic and foreign markets for different types of pilling machines .

1. Introduction to related terms

(1) Fuzzing: The fibers on the surface of the fabric protrude or ends of the fibers protrude to form fluff. Obvious surface changes caused by pile,

(2) Puff ball: a ball formed by a tangle of fibers that protrudes from the surface of the fabric, is dense, cannot not transmit light, and produces a projection. Lint changes and hairball formation may occur when washing, cleaningdry age, wear or use.

(3) Pilling: Pilling occurs on the surface of the fabric.

2. Pilling method

1. Pilling box method: installed in the specimen on the polyurethane tube is randomly turned over in a cork-covered wooden case at a constant rotation speed. After the specified number of turns, pilling performance is visually described and evaluated.

2. Random tumbling method: Place the sample into the test box. Under the rotation of the wheel, the cork liner of the box is continuously rubbed randomly. Once the set time is reached, take samples for evaluation.

3. Circular path method: According to the specified method and test parameters, use nylon brush and fabric abrasives or only fabric abrasives to cause the fburping and pilling of the sample. Then, under specified lighting conditions, the pilling performance was visually described and evaluated.

4. Martindale method: under the specified pressure, the circular sample on the sample holder and the abrasive on the grinding table (with the same cloth abrasive or wool as the test The sample is rubbed according to the Lissajous curve. The sample is allowed to rotate freely around a central axis perpendicular to the central axis.e plane of the specimen. After the specified friction period, the samples are evaluated to determine lint and pilling levels using a visual description.

3. Fabric pilling

The basic unit of fabric is yarn. During processing, scale is subject to combing, stretching and rubbing, so its surface is not smooth and lint will inevitably appear . DuringDuring the weighing process, the fabric is constantly subjected to the action of external forces, resulting in the gradual tearing off of lint or single filaments on the surface of the fabric. When the height and density of the fluff reach a certain value, the continuous action of external friction causes the fluff to tangle into balls. It is raised on the surface of the fabric. If the material is stiffer, it will not easily fall off due to friction after pilling, eventually forming a hairball.

Pilling of the fabric will deteriorate the appearance of the fabric and reduce its wearing performance. It is one of the important testing elements in business transactions.

To purchase a complete set of pilling tester, you need a tester with the most basic 6 detection stations. For more testing instruments, please visit http://www.schap.cn/
