GROUND-IN-CLAY SOILED DETERGENCY TEST CLOTHS
Soils and stains which are ground into the fibers of clothing are some of the most difficult to remove. Our ground-in-clay soiled cloth is designed to provide a controlled laboratory test material which simulates real life ground-in particulate soils. It is used widely to test home laundry detergents for their ability to handle particulate soils.
The soil we use is a 70 % slurry of natural clays selected to be representative of clay soils found in the home laundry. It is entirely particulate matter. A dark-red, iron-rich clay is one of the constituents and the iron mineral gives the stain a pinkish hue. The soil is a proprietary mixture of natural clays developed to make ground-in-clay soiled swatches that simulate the clay soiled cloths used by Colgate and described in the paper by J.T. Inatamorati, et al, J.Am. Oil Chem. Soc. 52 76-80 (1975).
Mechanical action by a proprietary process is used to force the clay particles into the spaces between the fibers. The soiling medium is a wet clay mud. The grinding action with wet clay is similar to the process which occurs with clothing worn in many outdoor activities.
We maintain a stock of two popular fabrics soiled with ground-in-clay. Most other fabrics in the Testfabrics, Inc catalog which are strong enough to withstand the mechanical action can be soiled to order. We produce the soiled cloths in the form of strips 4 inches wide by 6 feet long and can cut those to order. Our standard size and package is as follows:
Swatch Size 3 X 4 inches with pinked or fused edges
Swatches per Package 24
Stock Fabrics Cotton 400 Print Cloth
Cot. Polyester Durable Press 7435WRL
The technique we use for grinding in clay can be used to grind other soils into the fibers of cloth. We welcome your inquiries for other soils and stains
