Coated abrasive article

Abstract: The present invention provides a coated abrasive article, wherein the backing includes a tough, heat resistant, thermoplastic binder material, and an effective amount of a fibrous reinforcing material distributed throughout the thermoplastic binder material The abrasive grain adhered to the backing comprise rare earth oxide-modified alpha alumina-based abrasive grain, which exhibit a surprising improvement in grinding performance in conjunction with the backing

Package opening system

Abstract: A multilayer strip having an adhesive between layers, the adhesive containing frangible microcapsules carrying a fragrant liquid therein, can be used as a tear strip (8) for a package overwrap. Upon pulling the outward layer (12) of said strip, the overwrap is opened and the fragrance is released.

A coated abrasive belt with an endless, seamless backing and method of preparation

Abstract: A coated abrasive backing consisting of an endless, seamless, loop is provided. The backing loop includes 40-99 % by weight of an organic polymeric binder, based upon the weight of the backing; and an effective amount of a fibrous reinforcing material engulfed within the organic polymeric binder material. The endless, seamless backing loop includes a length with parallel side edges, and at least one layer of fibrous reinforcing material engulfed within the organic polymeric binder material such that there are regions of organic binder material free of fibrous reinforcing material on opposite surfaces of the layer of fibrous reinforcing material. The fibrous reinforcing material can be in the form of individual fibrous strands, a fibrous mat structure, or a combination of these. A method for preparing the endless, seamless backing loop for a coated abrasive belt is also provided. The method includes the steps of preparing a loop of liquid binder material having fibrous reinforcing material therein around the periphery of a drum; and solidifying the binder material such that an endless, seamless, backing loop having fibrous reinforcing material engulfed within the organic polymeric binder material is formed.

Loop fastener material storage/dispensing assembly

Abstract: A storage/dispensing assembly (10), e.g., a roll or stack, of loop fastener material such as is used in hook and loop fastening system comprising one or more multilayer sheets of loop fastener material (12) arranged such that the adhesive layer (18) of an overlying portion of the loop fastener material (12) is in direct contact with the loop layer (14) of an underlying portion of the loop fastener material (12). The loops are such that, when the overlying portion (12a) of the loop fastener material (12) is removed from the assembly (10), the loops of the underlying portion (14b) are presented in an engageable state. Also, a method for dispensing such loop material (12) from such assemblies (10) such that as the adhesive layer (18a) of the overlying portion (12a) is separated from the loops of the underlying portion (14b), the loops of the underlying portion (14b) are presented in an engageable state.

Isocyanate derivatives comprising fluorochemical oligomers

Abstract: Fluorochemical compositions comprising fluorinated compounds, wherein the fluorinated compound comprises fluorochemical oligomeric portion, an organic moiety, and a group that can impart soft hand, stain release, water repellency, or a durable property when the compound is applied to a fibrous substrate, wherein the fluorochemical oligomeric portion is bonded to the organic moiety through an isocyanate-derived linking group. Also disclosed are fluorochemical compositions in the form of fluorochemical liquid dispersions and methods for preparing substrates treated with such compositions. Substrates so treated exhibit particularly durable and abrasion-resistant oil and water repellent properties. Intermediates in the preparation of the fluorochemical compositions are also disclosed. Some of the intermediates are useful as emulsifiers in fluorochemical liquid dispersions.
