ISO 105-X12

Rubbing Resistance

Analytical methods that measure the transfer of dye from fabric surfaces to an un-dyed cotton cloth during friction simulate real-life wear. The test method iso 105-x12 defines the procedure for evaluating dry and wet rubbing fastness on all textile types. This standard identifies loose dye particles that could transfer to skin or other garments.

Test Mechanism

Mechanical crockmeters rub a dry and a wet rubbing cloth across the test specimen under a specified load. The iso 105-x12 protocol dictates the dimensions of the finger, the downward force, and the stroke frequency. This precise replication ensures that laboratory results are reproducible across different testing facilities.

Staining Assessment

Pigment transfers are graded against a standard gray scale for staining. Under the iso 105-x12 test, wet crocking ratings are typically lower than dry ratings because water releases dye. These ratings help determine if further washing is needed.

Production Significance

Dyehouses modify their finishing steps if pre-shipment samples fail to meet the required fastness levels. Failing results in the iso 105-x12 test often point to insufficient rinsing of unfixed dye after printing or dyeing. Adjusting the wash-off process or adding a fixing agent corrects this issue before final garment packaging, which ensures that apparel brands receive consistent shipments.
