- compositions Comprising Fatty Acid Chloride, Alkenyl Succinic Anhydride And/Or Alkyl Ketene Dimer
- the present invention relates to a coating material comprising a fatty acid chloride, an alkyl ketene dimer and a metal oxide.
- the present invention also relates to a coating composition comprising a fatty acid chloride, an alkyl ketene dimer, a metal oxide, and a solvent, a method of preparing the coating composition, a method of coating a substrate, use of the coating material or the composition to coat a substrate, a method of conferring hydrophobicity to a textile or fabric comprising the step of applying a coating material comprising alkenyl succinic anhydride to the textile or fabric, a method of softening a textile or fabric comprising the step of contacting a composition comprising fatty acid chloride, an alkenyl succinic anhydride, an alkyl ketene dimer or a mixture thereof and a solvent, with the textile or fabric, the use of alkenyl succinic anhydride to confer hydrophobicity to a textile or fabric and the use of
- Hydrophobic surfaces have extremely high repellency or extremely low affinity for water. Hydrophobicity of a material is determined by the contact angle of a water droplet on the surface. Generally Hydrophobic surface is understood as a surface that has a water droplet contact angle higher than 90°. Most superhydrophobic coatings made by currently available technologies are not durable. The coatings do not have good adhesion to the substrate, so they are easily scratched off, the coating deteriorates over time, and are often made from non-renewable resources.
- textiles particularly those made of cellulose fibers after washing becomes hard and coarse and unpleasant to the touch after drying.
- This undesired hardness generally can be overcome by treating the fabric after washing by rinsing with liquid dispersions of cationic compounds, such as a cationic fabric softening agent dispersed in water.
- Fabric softener or conditioning compositions are commonly used to impart a fabric softening effect onto a fabric.
- the fabric softening effect is lost and the fabric again becomes unpleasant to touch after drying, making it necessary to use a fabric softener every time after washing.
- a coating material comprising a fatty acid chloride, an alkyl ketene dimer and a metal oxide.
- the coating material may be used as a hydrophobic coating for maintenance, enhancement and protection of various substrates from water, to prevent oxidation of surfaces in air and moisture, especially for cellulosic materials such as wood, leather, cotton textiles, fabric, filters, membranes, and paint, where hydrophobic surfaces are particularly desired.
- the coating material may have water repellent, self-cleaning, corrosion resistant, antifungal, and/or antibacterial properties.
- the coating material may have anti-mold properties.
- the coating may be strongly bonded to the surface of a substrate, rather than simply physically adsorbed onto the surface of the substrate by electrostatic interactions, thereby extending the durability of the hydrophobic effect.
- the strong bonding may be facilitated by the long fatty acid/ester groups of the components of the coating material, i.e. the fatty acid chloride and alkyl ketene dimer, with the surface.
- the use of a combination of the fatty acid chloride, alkyl ketene dimer and metal oxide may prevent the degradation of the substrate such as wood, leather, textile or fabric. Degradation of the substrate may occur if only one of fatty acid chloride or alkyl ketene dimer is used to coat the substrate. However, by using a combination of the fatty acid chloride, alkyl ketene dimer and metal oxide, this may be prevented.
- the metal oxide may facilitate the coating process and provide the substrate with UV- protection.
- a coating composition comprising a fatty acid chloride, an alkyl ketene dimer, a metal oxide, and a solvent.
- a method of preparing the coating composition as defined above comprising the step of contacting a fatty acid chloride, an alkyl ketene dimer and a metal oxide with a solvent.
- there is a method of coating a substrate comprising the step of applying the coating material as defined above or the coating composition as defined above onto the substrate.
- a method of conferring hydrophobicity to a textile or fabric comprising the step of applying a coating material comprising alkenyl succinic anhydride onto the textile or fabric.
- a coating material comprising alkenyl succinic anhydride onto the textile or fabric.
- an alkenyl succinic anhydride to confer hydrophobicity to a textile or fabric.
- alkenyl succinic anhydride may confer hydrophobicity to a substrate.
- the alkenyl succinic anhydride may be more reactive or may bind more strongly to a textile or fabric than the alkyl ketene dimer.
- the alkenyl succinic anhydride may also be less corrosive on the textile or fabric with respect to fatty acid chloride.
- a method of softening a textile or fabric comprising the step of contacting a composition comprising fatty acid chloride, an alkenyl succinic anhydride, an alkyl ketene dimer or a mixture thereof and a solvent, with the textile or fabric.
- composition comprising fatty acid chloride, an alkenyl succinic anhydride, an alkyl ketene dimer or a mixture thereof and a solvent, as a textile softener or a fabric softener.
- relatively low concentrations (less than 10% w/v) of fatty acid chloride, alkenyl succinic anhydride, alkyl ketene dimer or a mixture thereof may have textile or fabric softening properties and may act as an alternative to ammonium-based fabric softeners.
- fatty acid chloride, alkenyl succinic anhydride, alkyl ketene dimer or a mixture thereof may have long-lasting textile or fabric softening effects compared to conventional textile or fabric softeners.
- the fatty acid chloride, alkenyl succinic anhydride, alkyl ketene dimer or a mixture thereof may strongly bind to the textile or fabric, rather than being simply physically adsorbed onto the surface of the textile or fabric by electrostatic interactions.
- the strong bonding may extend the durability of the softening effect of the fabric or textile.
- the strong bonding may be facilitated by the long fatty acid/anhydride/ester groups of the composition, i.e. the fatty acid chloride, alkenyl succinic anhydride, or alkyl ketene dimer, with the surface.
- the long fatty acid/ester groups may strongly attach to the surface of the fabric or textile, which may impart lubricity to the fabric or textile by lining up with the fibres. This may be different to the mechanism of conventional fabric softeners which may act by neutralizing the negative charge on the surface of the fabric or the textile.
