Improved fibers are provided that may be incorporated into absorbent articles such as disposable diapers, feminine hygiene appliances, and bandages. Water soluble particles are bound to fibrous material by a binder in which the particles are sparingly soluble and which has a volatility less than water. The binder has a functional group capable of forming a hydrogen bond with the fibers, and a functional group that is capable of forming a hydrogen bond or a coordinate covalent bond with the particles. The binder can be activated or reactivated by addition of heat, liquid, or mechanical energy such that fibers treated with binder may be shipped to a distribution point before particles are bound to the fibers.

Fibers with adhered particles, comprising: particles with a hydrogen bonding or a coordinate covalent bonding functionality, the particles being water soluble; fibers that have hydrogen bonding functional sites; and a binder on the fibers, the binder having a volatility less than water, the binder comprising binder molecules, the binder molecules having at least one functional group that is capable of forming a hydrogen bond with the fibers, and at least one functional group that is capable of forming a hydrogen bond or coordinate covalent bond with the particles, wherein the particles are sparingly soluble in the binder, and the binder being present in an amount of at least 1 percent by weight of the fibers and which is sufficient to bind a substantial portion of the particles to the fibers primarily by a hydrogen bond or coordinate covalent bond.
