Patent number: 6613862Abstract: A process is described which imparts exceptional antisoiling, anti-staining and repellent properties to carpets. The process makes use of a water-based exhaustion process wherein the water-based treating solution contains (1) glassy fluorochemical material, glassy hydrocarbon material, or combinations thereof; (2) a stainblocking material; (3) a polyvalent metal salt, acid, or combinations thereof; and (4) water. Subsequent to exhaustion, the wet treated carpet is heated, usually in a steaming step, rinsed, and dried in a dry heat oven.Type: GrantFiled: February 1, 2001Date of Patent: September 2, 2003Assignee: 3M Innovative Properties CompanyInventors: John C.

Publication number: 20020102382Abstract: The invention relates to water dispersible finishing compositions for fibrous substrates including fibers, fabrics, carpets, nonwoven webs, and the like. The finishing compositions can impart to the fibrous substrate soil resistance and a range of hydrophilic properties from water repellency to water absorbency. Preferably, the finishing compositions can impart stain resistance to the fibrous substrate. The invention also relates to methods for treating fibrous substrates with the finishing compositions of this invention. The compositions can be applied to the substrate and subsequently cured at ambient temperature or above.Type: ApplicationFiled: December 1, 2000Publication date: August 1, 2002Applicant: 3M Innovative Properties CompanyInventors: Gary W.

Patent number: 4935287Abstract: Stretchable laminate constructions based on an elastic fabric and a substantially non-elastic film which are held in intimate contact with one another by means of a discontinuous pattern of adhesive are disclosed. When the laminate constructions of the invention are in a relaxed state, the length of the film between adjacent adhesion points along the direction of stretch of the elastic fabric is substantially equivalent to the length of the elastic fabric between the same adhesion points when the construction is extended to its elastic recovery limit. A preferred embodiment of the invention utilizes waterproof breathable non-elastic membranes to produce laminate constructions suitable for clean room and protective garment applications.Type: GrantFiled: August 30, 1989Date of Patent: June 19, 1990Assignee: Minnesota Mining and Manufacturing CompanyInventors: Brian D.

Patent number: 4613544Abstract: A waterproof, moisture-vapor permeable unitary sheet material comprises a microporous polymeric matrix having pores comprising continuous passages extending through its thickness and opening into the opposite surfaces thereof, the passages being sufficiently filled with a moisture-vapor permeable, water-impermeable, hydrophilic material to prevent the passage of water and other liquids through the unitary sheet material while readily permitting moisture vapor transmission therethrough rendering the sheet material breathable. The unitary sheet is made by causing a liquid composition comprising the hydrophilic material or precursor thereof to flow into the pores of the matrix, then causing the conversion thereof to solid hydrophilic material.Type: GrantFiled: December 4, 1984Date of Patent: September 23, 1986Assignee: Minnesota Mining and Manufacturing Co.Inventor: Malcolm B.
