The engraved roller transfers a well-defined amount of the thinner oily soil media to the substrate without actually saturating the fabrics so much as to make them too soaked to be of any value. Using a hand brush for prototype application of soil media to the roller instead of the full production roller brush gives us great flexibility in this effort. Making more volume would eventually require the purchase of an individual roller brush applicator per soil media to insure against contamination of one media to another. Polyester film backs the substrate to block front to back soil transfer. We have produced a used peanut frying oil cotton soil test cloth in this manner and there is a definitive color to assist in evaluating removal interpretation.
Samples are available at the booth or on request.
Other oily soils of this nature are possible to apply in this manner and we could add some oil soluble dyes to some of the colorless oils to provide some visual removal determination. We would sincerely appreciate your input as to what problem oily soil media you would like us to try. If you have some suggestions, or have some potential candidates you would like to submit for custom soiling, please let us know. This may also be a viable means of producing some malodor test materials. Please let us know if you have some knowledge of appropriate media for such a product.
