Abstract: Spunbond multicomponent filaments and nonwoven webs made from the filaments are disclosed. In accordance with the present invention, the multicomponent filaments contain a crimp enhancement additive. Specifically, the crimp enhancement additive is added to one of the polymeric components in order to accelerate its solidification rate. The additive enhances crimp, allows for highly crimped filaments to be made at smaller deniers, and produces low density webs with improved stretch and cloth-like properties. Specifically, the additive incorporated into the filaments is a nonionic surfactant such as an alkyl ether alkoxylate, a siloxane alkoxylate, an ester of a polyalkylene glycol, a polysaccharide derivative, a glycerol ester, or mixtures thereof.

Abstract: This invention describes water-based microsphere adhesive formulations to be used in the sheet-to-sheet coating process. These adhesives have proven to have excellent wet-out of a difficult, high-energy surface, good shear stability to allow die-coating or gravure-coating of the adhesive onto an intermediate carrier belt, good elasticity to allow the wet adhesive to cling to the intermediate belt until it is dried (or partially dried), good integrity to allow complete transfer from the intermediate carrier belt onto the final substrate, and repositionable properties in a final product composition.

Abstract: An embossed paper laminate having two laminae is provided. The laminae are joined such that there is at least one zone of the laminate wherein the peel strength of the laminate in that zone is greater than the peel strength of the laminate in other zones of the laminated paper product. The laminate is made by two close tolerance pattern rolls juxtaposed to form a nip. Each pattern roll has radially extending protuberances which contact the periphery of the other pattern roll intermediate its protuberances. The laminae are fed through the nip in face-to-face relationship and are embossed and adhesively joined to the other lamina by the radially extending protuberances. The laminating adhesive is supplied to the various zones of the laminated paper product at a level that is appropriate for providing the requisite peel strength for that zone.

Abstract: Techniques and apparatus for the laser induced etching of a reactive material, or of a multilayer substrate or wafer comprising layers of materials of different etching characteristics and reactivities, are disclosed. Short wavelength laser radiation and control of the process ambient equalize etch rates of the layers of a multilayer substrate or wafer and allow high-resolution etching. A suppressant gas introduced into a halogen-containing ambient suppresses explosive reactions between the ambient and reactive materials or layers. For less reactive layers or materials, reduced-pressure air is a suitable ambient. The techniques and apparatus disclosed herein are particularly useful in the manufacture of magnetic data transfer heads.

Abstract: This invention describes two products both with a plain, nonperforated surface visual consisting of a fiberboard substrate with or without a laminated porous nonwoven scrim and then a finished painted surface. The finish painted surface decorates or finishes the board, but most important, must remain acoustically transparent to retain the sound absorption properties of the fiberboard prior to painting. The fiberboard substrate is made to be porous or modified with hole perforations to cause it to be a good sound absorber. If the fiberboard substrate is sufficiently porous without hole perforations, then the sprayable, high solids, porous paint can be directly applied. If hole perforations are used to improve the sound absorption properties of the board substrate, then a porous, nonwoven scrim is attached and painted using the same high solids porous paint. This painted scrim must be sufficiently optically opaque to hide the hole punched board, yet sufficiently open to render it acoustically transparent.

Abstract: A non-asbestos friction material containing a reinforcing fiber other than asbestos, organic fillers, friction adjusting ingredients, and a thermosetting resin for binding the reinforcing fiber, the organic fillers and the friction adjusting ingredients together. The friction adjusting ingredients contain magnesia in the form of aggregated particles which are an aggregate of minute particles. The use of magnesia in the form of aggregated particles reduces low-frequency noise and squeak while keeping the attack on the mating member low and keeping high the resistance to fading and the coefficient of friction.
