Abstract
Methods of manufacturing a substrate including a component, such as superabsorbent material, having a volatile hydrophobic coating are disclosed. The method can include providing a fluid supply including a liquid and providing a supply of the component. The component can include a volatile hydrophobic coating. The method can include introducing the component to the fluid supply. The method can also include transferring the component in the fluid supply to provide the substrate. The method can further include applying heat to the substrate. The heat can remove the volatile hydrophobic coating from the component.
Claims14
A method of manufacturing a substrate including a component, the method comprising:
- providing a fluid supply including a liquid;
- providing a supply of the component, the component comprising a volatile hydrophobic coating, wherein the volatile hydrophobic coating comprises from 1% to 35% by weight of the component;
- introducing the component to the fluid supply by mixing the component into the fluid supply, the volatile hydrophobic coating including a rate of dissolution such that the volatile hydrophobic coating temporarily protects the component from the liquid of the first fluid supply;
- transferring the component in the fluid supply to provide the substrate;
- and
- applying heat to the substrate;
- the heat removing the volatile hydrophobic coating from the component.
A method of handling a superabsorbent material, the method comprising:
- providing a fluid supply including a liquid, wherein the fluid supply comprises a foam including the liquid, a gas, a surfactant, and wherein fibers are dispersed in the foam;
- providing a supply of the superabsorbent material, the superabsorbent material comprising a volatile hydrophobic coating, wherein the volatile hydrophobic coating comprises from 1% to 35% by weight of the superabsorbent material;
- introducing the superabsorbent material to the fluid supply, the volatile hydrophobic coating including a rate of dissolution such that the volatile hydrophobic coating temporarily protects the superabsorbent material from the liquid of the first fluid supply;
- and
- applying heat to the superabsorbent material;
- the heat removing the volatile hydrophobic coating from the superabsorbent material.
