Soil repellent finish is to remove pollution caused either by water or oil. Technically, this type of finishing belongs to water repellency category. Soil repellent finish can repel two types of pollution (water or oil).
Currently, most of soil release finish techniques involve acrylic acid and/or a polymer. Soil release finish mainly involves pressing at 110 degrees fahrenheit, pad or dry. This type of combination is mostly done in mixture of polyester and cotton. Additives enable resistance against oil-soluble stains, and foster removal of stains during washing.
Removing oil-soluble stains is especially important to polyester which is highly affinitive to oil or oil-soluble pollutants. Acryl attaches to fabric. The following describes how acrylic stains are removed.
1. Acryl becomes negative ions in water. Therefore, it repulses negative ionic stains.
2. Coating conceals niches of fabric. It therefore keeps the surface clean by repelling stains.
3. This processing increases surface tension, thereby easing removal of layers of stain.
4. This processing is both lilophilic and hydrophilic.
5. In water, expansion of polymer forms sufficient mechanical power onto significant stains.
This processing may have flaws when applied to P/C mixture and other types of mixed fabrics.
Processed fabrics may become stiff. Soil repellent finish done on synthetic fabrics including polyeste is not effective with currently used detergents.
Specifically, for synthetic fabric to more prosper in clothing market, recently produced acrylic grafted polyester fabric is “wickable” in order to enable soil repellency and to increase absorption.
