How to Measure Color Fastness to Rubbing?

Rubbing shading speed is one of the essential characteristics for good clothes. Here is some data about rubbing shading speed. This may enable you to make a further advance into enhancing your clothing item quality.

1. Rubbing Shading Quickness

Rubbing shading quickness alludes to capacity to maintain unique shade of colored textures when rubbing. Dry rubbing shading quickness alludes to the circumstance of blurring and recoloring of colored texture when rubbed with standard white cloth. Wet rubbing shading quickness alludes to the circumstance of blurring and recoloring of colored texture when rubbed with standard white cloth which water content is 95% to 105%. The assessment of Rubbing shading speed relies upon the level of recoloring of white cloth. In the wake of testing, the white cloth is contrasted with recoloring test cards to gauge recoloring speed. Rubbing shading speed, same as washing shading speed, partition into 5 evaluations and 9 documents, among which review 5 is the best and grade 1 is the most exceedingly awful. The contact blurring of texture is to influence color to tumble off caused by grating. Wet rubbing is impacted by both outer power and water, so it is around one level lower than dry rubbing.

B. Testing Technique

an) Example Arrangement

On the off chance that tried specimen is texture or cover, you should get ready two gatherings of tests with no under 50mm*200mm, and each gathering contains two examples. One gathering is the length direction of tests is paralleled to twist yarn, used to dry rubbing and wet rubbing in twist direction; the other is the longitudinal direction of tests is paralleled to weft yarn, used to dry rubbing and wet rubbing in weft direction.

In the event that the specimen is multi shading, you ought to pick test's position precisely and let each shading rubbing. On the off chance that the territory of each shading is sufficiently substantial, you should take all specimens.

In the event that tried example is yarn, you need to weave it as a texture and guarantee its size in no under 50mm*200mm; or yarn is winded parallelly in a paperboard whose size is same as tried specimen.

b) Working Strategy

Rubbing cloth ought to receive cotton semi-finished textures which have been desized, scoured, blanched and don't contain any finishing operator.

Tried specimen is settled on the base floor of the analyzer by bracing gadget, and its length direction is as per the development direction of the analyzer.

Dry rubbing cloth is settled on erosion head of analyzer, and the twist direction of it is as per the development direction of grinding head.

Press Begin Switch, responding rub for 10 times in 10s (responding development is 100mm, the vertical weight is 9N), at that point take the get rubbing cloth dry.

Taking another rubbing cloth, and moving it on moving liquid gadget after absorbed cool water, to influence moisture to content controlled in 95% to 105%.

To do the above operation of dry rubbing cloth more than once. When rubbing is finished, dry it at room temperature.

Utilizing dark cards assessing recoloring to gauge the recoloring quickness of above dry and wet rubbing clothes.

Crockmeter (manual sort and programmed sort) is generally utilized as a part of Rubbing Shading Speed Test.
