Abstract
Discontinuous fibers are coated with a binder material with the binder material adhering the fibers to super absorbent particles. Fibers in the product are substantially unbonded except to the super absorbent particles. The binder may be present at an amount which is sufficient to substantially continuously coat the fibers. Plural coatings of various binder materials may be used. The binder material may be heat fusible or heat curable and the treated fibers mixed with other fibers for use in producing a wide variety of products.
Claims16
A fiber product of discontinuous individual fibers, the individual fibers being substantially continuously coated with a binder material which is included in an amount which is at least seven percent by weight to the weight of the cellulose fiber and the binder material and in which solid particles of super absorbent material are adhered to the fibers by the binder material without binder material coating the particles, a substantial majority of the individual fibers being substantially unbounded together.
A cellulose based product of individual cellulose fibers, the individual fibers being substantially continuously coated with a binder material which is included in an amount which is at least seven percent by weight to the weight of the cellulose fibers and the binder material and in which solid particles of super absorbent material are adhered to the cellulose fibers by the binder material without such particles being covered by the binder material, the individual cellulose fibers being substantially unbonded together other than by the particles of super absorbent material.
A fiber product comprising discontinuous individual cellulose fibers, the individual cellulose fibers being substantially continuously coated with a binder material which is included in an amount which is at least seven percent by weight to the weight of the cellulose fibers and the binder material, solid particles of super absorbent material being adhered to the fibers by the binder material without such particles being covered by the binder material, a substantial majority of the individual cellulose fibers being substantially unbonded together.
