Textile Soils

The maintenance of a textile product after purchase is of prime interest to the consumer and to commercial fabric care operations. The major factor to be eonsidered is cleaning and soil removal of the textile during continued use. In order to have a fuller understanding of the cleaning process, one must examine the nature of textile soils, detergency, and soil removal, and the wet (laundering) or dry (solvent) cleaning processes used. 

Soils come from a number of sources in the environment that textile structures are subjected to during wear and use. These soils include (1) solid particulate matter (clays, minerals, soot), (2) oil-bome soils (fats, greases, etc.), and (3) water-borne soils (water-soluble salts, etc.). Solid particulate matter such as clays, metal oxides, and soot is often mixed with water- and oil-borne soils but can also soil a textile alone through appl ication in the dry state. When appl ied from the dry state, these solid soils can often be removed by mechanical action such as brushing and shaking. 

Clays in general are complex inorganic silicates with color derived from the structure of the silicate. Oil-borne soils are organic hydrocarbons or related derivatives which are soluble in oils. The aliphatic and aromatic hydrocarbons and fatty acid esters of glycerol are the most predominant oil-borne soils. Less polar hydrocarbons such as mineral oil are more easily removed from textile substrates than are the more polar glycerol esters of fatty acids. Carbon-based matter such as soot is not

The first project on the removal of pesticide residues from fabrics by laundering or "pesticide decontamination" was a part of a doctoral dissertation by Elizabeth Easter and Is published in the March 1983 AATCC journal (4). This project was undertaken to determine if a relationship does in fact exist between the removal of pesticide residues and the removal of common soil. In textiles, "soiling denotes the undesirable accumulation of oily and/or particulate materials on fabrics (6). As significant levels of pesticide residues in workers clothing have been reported by researchers, these socalled "contaminated" fabrics may also be defined as "soiled" fabrics (5, 7, 8).
