Test Multifibre fabric is a standardized test fabric used for assessing colorfastness and color transfer in textiles. It is designed to simulate a variety of fabric types commonly used in the industry. The Multifibre fabric is used in tests such as the AATCC (American Association of Textile Chemists and Colorists) Test Method 61 for colorfastness to laundering and the ISO (International Organization for Standardization) 105-C series of tests for colorfastness to various factors.

The Multifibre fabric is made by weaving different types of fibers into a single fabric, thus simulating a variety of common fabric compositions. The fibers used can include cotton, wool, polyester, nylon, and other synthetic and natural fibers. These fibers have different affinities to dyes and respond differently to various testing conditions.

  • Colorfastness to Laundering: This test evaluates how well a fabric retains its color after being subjected to repeated washing and drying cycles. The Multifibre fabric helps assess color transfer and staining that may occur during washing.
  • Colorfastness to Crocking: Also known as the rubbing test, this test assesses color transfer from fabric onto another surface when subjected to rubbing or friction. The Multifibre fabric is used as the rubbing cloth to evaluate colorfastness.
  • Colorfastness to Light: This test measures the fabric's ability to retain its color when exposed to light. The Multifibre fabric is used as a reference standard to evaluate color changes in the tested fabric.
  • Colorfastness to Perspiration: This test evaluates colorfastness to perspiration and can help assess whether the fabric stains or loses color when in contact with sweat.

Using a Multifibre fabric in these tests allows for consistent and reliable assessments of colorfastness across different fabric types. The fabric is readily available from suppliers specializing in textile testing materials and equipment.
