Abstract
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.
