摘要:
The blood absorbence properties, e.g., free swell blood absorbence capacity and after load blood absorbence capacity of superabsorbent materials is enhanced by combining the superabsorbent materials with enhancing agents which serve to enhance the blood absorbent properties thereof. The enhancing agents can be applied to the superabsorbent materials or they can be provided on a fibrous material to be combined with the superabsorbent materials. The enhancing agents are selected from materials that include functionalities that allow them to hydrogen bond to the superabsorbent material when the enhancing agent is applied directly thereto or combined with materials to which the enhancing agents have been applied.

摘要:
A fiber product comprises dry discontinuous fibers having a starch binder on at least a portion of the fiber surfaces, at least about seventy percent of the starch binder coated fibers being unbonded to one another, solid particles are adhered to the fibers by the binder without the binder entirely coating the particles. The fibers may be air laid into a web or formed into an absorbent structure. Superabsorbent particles are a specific example of the particles which may be adhered to the fibers.

The blood absorbence properties, e.g., free swell blood absorbence capacity and after load blood absorbence capacity of superabsorbent materials is enhanced by combining the superabsorbent materials with enhancing agents which serve to enhance the blood absorbent properties thereof. The enhancing agents in amounts ranging from about 0.01-8 weight percent is applied to the superabsorbent materials or they can be provided on a fibrous material to be combined with the superabsorbent materials. The enhancing agents are selected from materials that include functionalities that allow them to hydrogen bond to the superabsorbent material when the enhancing agent is applied directly thereto or combined with materials to which the enhancing agents have been applied.
摘要:
A binder is applied to particles which are then combined with fibers to bind the particles to the fibers. The particles have functional sites for forming a hydrogen bond or a coordinate covalent bond. The fibers have hydrogen bonding functional sites. The binder comprises binder molecules, the binder molecules having at least one functional group that is capable of forming a hydrogen bond or a coordinate covalent bond with the particles, and at least one functional group that is capable of forming a hydrogen bond with the fibers. A substantial portion of the particles that are adhered to the fibers may be adhered in particulate form by hydrogen bonds or coordinate covalent bonds to the binder, and the binder in turn may be adhered to the fibers by hydrogen bonds. Fibers containing particles bound by this method are easily densified.
摘要:
Binder is applied to fibers during the production of a web on a wet laid sheet manufacturing line. Particles are bound to fibrous material by a binder that has a volatility less than water, wherein 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 may 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. The binder may be a polymeric binder selected from the group consisting of polyethylene glycol, polypropylene glycol, polyacrylic acid, polyamides and polyamines, and in which the polymeric binder has a hydrogen bonding functionality or coordinate covalent bond forming functionality on each repeating unit of the polymeric binder. Alternatively, the binder may be a non-polymeric organic binder that includes a functionality such as a carboxylic acid, an alcohol, an amino acid, an amide, and an amine, wherein there are at least two such functionalities on the molecule, which may be the same or different functionality. Particles attached to the fibers in this manner are firmly adhered and are not easily dislodged. Fibrous products produced by this method include fibers to which particles are bound and may also include other fibers.
摘要:
A method of producing easily densified high bulk fibers that have adhered particulates. The high bulk fibers have hydrogen bonding or coordinate covalent bonding functionalities, and a binder is applied to the fibers to bind the particles to the fibers. The binder has a functional group that forms a hydrogen bond or a coordinate covalent bond with the particles, and a functional group that forms a hydrogen bond with the fibers. A substantial portion of the particles that are adhered to the fibers are adhered in particulate form by hydrogen bonds or coordinate covalent bonds to the binder, and the binder is in turn adhered to the fibers by hydrogen bonds. Fibers containing particles bound by this method are easily densified.
摘要:
Particles are bound to fibrous material by a polymeric binder selected from the group consisting of poly(caprolactone) diol, polyamides and polyamines. The polymeric binder has a hydrogen bonding functionality or coordinate covalent bond forming functionality on each repeating unit of the polymeric binder. As a specific example, the fibrous material is cellulosic fibers and the particles are superabsorbent particles. Preferably 3-80 percent binder and 0.05-80 percent particles, by weight of the total weight of the fibrous material, binder and particles are included. The binder preferably has a molecular weight greater than 500 grams/mole, preferably 4,000-8,000 grams/mole. Particles attached to the fibers in this manner are firmly adhered and are not easily dislodged. Fibrous products produced by this method include fibers to which particles are bound, and fibers which have been treated with the binder but to which particles are not bound.

A height adjustable universal creeper comprises a moveable base, interchangeable posts, extension members, a cushioned platform mounted upon a frame which is mounted upon the extension members, and rungs attached to a long post and spaced apart along the length of the long post. A tray is slidably mounted beneath the platform near a terminal end of the frame and has a compartment to conveniently store tools, accessories, and the like. The height adjustable creeper is very versatile and can be easily adjusted not only above hard-to-reach work areas such as engine compartments of vehicles but also beneath the work areas such as beneath the vehicles.
