to other applications as discussed earlier the process consists of two major steps namely fwa loading of the fiber lumen and the sealing of the fiber so that the fwa is retained these are described in more detail below first the fwa is dissolved in a suitable solvent in the current embodiment of the prevent invention the solvent is methanol but another suitable solvent can be chosen by anyone skilled in the art the amount of fwa dissolved in the solvent can vary according to the application the fwa solvent mixture can be directly mixed with paper fibers however one can use water with certain solvents to increase the safety of the operation safety is improved because the solvent water mixture is not as flammable as the pure solvent examples of solvents that are miscible with water include ethanol methanol and many other alcohols it should be noted that the fwa may dissolve in water thereby making this safety point nonapplicable after the fiber fwa solution is combined the entire solution is vigorously mixed for a period of time causing the dissolved fwa to migrate into the lumen under these conditions the fwa is said to be 34 lumen loaded 34 into the fiber this vigorous mixing can be accomplished by use of a conventional 34 disintegrator 34 a disintegrator is standard pulp laboratory or pulping equipment and is commonly used to uniformly disperse the papermaking fibers within the solution with the minimum amount of fiber cutting damage it is believed that the vigorous stirring causes two phenomena to be accomplished namely it ensures that the fwa and fibers are well mixed there are no concentration gradients within the system and it causes some fiber flexing which pumps fluid in and out of the fiber lumen thereby distributing the.
