Abstract: A process is provided for forming a super absorbent composite for use in personal hygiene products, comprising a non-woven core with SAP uniformly distributed throughout the thickness of the core and bonded to the core with an adhesive. A non-woven core is provided to a processing line. An adhesive is introduced throughout the thickness of the core. Then the core is impregnated with a super absorbent polymer by blowing a stream of super absorbent polymer and air onto the core at a sufficiently high velocity to cause the super absorbent polymer to penetrate the surface of the core. The super absorbent polymer is distributed uniformly throughout the cross-section of the non-woven core and immobilized by the adhesive. Alternatively, the super absorbent polymer is blown into a non-woven core without adhesive and immobilized by a fiber matrix in the non-woven core.

Abstract: Mechanical creping of fibrous webs is improved by employing two creping adhesives applied at different points in the papermaking process and having relatively different adhesive properties for adhering the web to the creping surface. The process crepes the web from a conventional creping surface by applying a layer of a first creping adhesive directly onto the creping surface while applying a second creping adhesive to the web, followed by pressing the web onto the already formed layer of first creping adhesive and then creping the web from the creping surface.
