What are the requirements for textile pilling tests and samples?

Author:QINSUN Released in:2022-12 Click:119

Product Description:

People wear clothes for a long time or after washing the clothes, the fiber heads on the surface of the fabric will be loosened by friction and slippage, and exposed to the surface of the fabric, forming fluff. These bristles have good wear resistance, and if they continue to be rubbed by the outside world, they will tangle into small balls and pilling will occur. Pilling is one of the important factors affecting the feel, appearance and wearability of fabric, and it is also an important factor in clothing products. An important quality indicator. The four conventional pilling test methods mainly include: circular track method, martindale method, roller box method and random drum method. At present, our company can provide you with the following two test methods. Physical performance testsand chemical fabrics, including but not limited to cotton, linen, silk, woolen fabrics, leather fabrics, chemical fiber fabrics, blended fabrics, modal fabrics, etc.

1. Round trajectory method

This method is mainly used on woven and knitted fabrics and is more common.

Test principle:

According to the specified test method and parameters, use a nylon brush and cloth abrasive or simply an abrasive cloth The sample is rubbed and pilled. The pilling behavior was then assessed visually under the specified lighting conditions. The circular path process parameters can be selected according to the type of fabric. If there is a product standard, it can be based on the requirements of the product standard: such as B. the requirements of GB/T4802.1-2008.

2. Martindale method

This method is mainlyAlso used for knitted fabrics, woven fabrics, especially home textiles.

Principle of the test: rubs under the specified pressure the circular sample in the trajectory of the Lissajous figure on the same cloth or woolen abrasive cloth. Freely rotate the sample box around the central axis perpendicular to the plane of the sample. After the specified rub time, the specimens are evaluated for lint or pilling using a visual description. Commonly used standards: such as GB/T4802.2-2008ISO5670, BS3424/5690, BSENISO12947-1, BSENISO12945-2, etc.

3. Rolling box method

This method is mainly used for knitted fabrics, especially knitted fabrics. oldest boy.

Principle of the test:

The sample mounted on a polyurethane The box can be rotated as desired. After the specified number of turns, the behavior of fuzzing and (or) pilling is assessed visually.

Commonly used standards: GB/T4802.3, ISO12945.1, BS5811, JISL1076, IWSTM152, M&SP18, P18B, P18C, P21A, NEXT19, etc. 4 Methods Testing principle:

The randomly rotating pilling tester can detect the pilling behavior of fabrics. Under the rotation of the stainless steel blades in the independent stainless steel sample test chamber, the fabric to be tested and the cork liner are rubbed continuously and randomly, and the test time is controlled by a timer and a audible alarm. Compressed air can also be blown into the test chamber to increase the rotational friction effect.
