Dirt sticks to textiles in different methods, mostly depending on the type of dust and textile attributes.
(surfactant powder)
1. Fluid oily dirt: generally adsorbed on fabrics through van der Waals forces. Non-polar mineral oil dirt sticks securely to hydrophobic fibers such as polyester and polypropylene, yet is fairly easy to eliminate on hydrophilic cotton fibers.
2. Water-soluble dirt: adsorbs firmly on hydrophilic textiles such as cotton fibers and is challenging to remove, yet is simple to fall off on hydrophobic fibers such as polyester and polypropylene.
3. Solid dust: The adsorption method is complicated, consisting of being secured by twisted fibers, being wrapped in between fibers, and being adsorbed on the concave or smooth surface of the fiber surface.
According to the pressure category, the adhesion of dust on materials can be summed up as complies with:
( surfactants fight dirt adhesion)
1. Mechanical force bond: solid dust particles follow the material with the air flow, which is influenced by the density, structure and fiber features of the textile. This sort of dirt is easy to fall off during washing, but it is challenging to remove when the fragment dimension is much less than 0.1 μm.
2. Van der Waals pressure adhesion: triggered by intermolecular electrostatic destination, induction force and diffusion pressure, it is the major factor for dust adhesion. Electrostatic attraction is particularly substantial between fibers and dirt with contrary fees, and multivalent cations can boost this adsorption.
3. Chemical bonding pressure attachment: Dust forms hydrogen bonds, ionic bonds and various other chemical bonds with fibers, such as clay, fats, protein dirt, dyes, ink, and so on. Once securely bonded, it is tough to eliminate.
