Abstract

Synthetic fabrics of polyesters improve in comparison to cotton the durability of apparels and household linen but lead due to their hydrophobic characteristics to problems of removal greasy soil which have a high affinity for hydrophobic synthetic fabrics improving their adhering to the hydrophobic fiber. The hydrophilic cotton fiber absorbs, by contrast, water quite well in the washing process, which makes the soil and stains easier to remove.
By physical absorbing of Repel-O-Tex® Soil Release Soil Polymers (SRP) interactions between synthetic fabric and greasy soil are reduced and their surface hydrophilicity is enhanced making stain removal easier. Already at the first wash a strong adhesion of soil particles on the fibers is prevented and in the second the soil removal becomes much easier. In the following washing cycles the washing effect will be enhanced by obtaining the whiteness of the fibers without a build-up effect on the surface.
