Abstract

A method is disclosed for strengthening a paper or textile article. The method involves (a) applying to the article a solution of an amorphous fluoropolymer in a perfluoroalkane solvent; and (b) drying the article. Also disclosed are strengthened paper and textile articles which include a fibrous paper or textile substrate, and amorphous fluoropolymer interconnecting fibers of the substrate.

Claims

Minneapolis, MN). In general, the perfluoroalkane solvents used in these solutions are not considered aggressive to many paper and textile articles. Most inks will not dissolve in perfluorinated solvents. Similarly, many substrates are unaffected by exposure to these solvents. The fluoropolymer solutions may be applied to the fibrous articles by common coating methods, including but not limited to spray application, dipping and brushing. After application of the solutions, the articles can be dried by conventional methods (e.g., air or vacuum drying).
EXAMPLES Fluoropolymer Solution Preparation:
Teflon® AF solutions were used in the examples below, and were used as received from E. I. du Pont de Nemours and Company, Wilmington, DE, unless otherwise noted. To dilute the Teflon® AF2130, solvent (FC-75, 3M, Minneapolis, MN) was weighed and was placed into a container, with the calculated amount of Teflon® AF2130 added to the solvent. The samples were mixed before use.
EXAMPLE 1 Paper Treatment Several types of paper, including newsprint and copier paper were dipped for about 30 seconds into several Teflon® AF solutions, having concentrations between 1 and 6% solids by weight, such that about half the sheet was impregnated with the solution. The papers were removed from the solution and dried for about 30 minutes. The entire sheets of paper were immersed in water at room temperature. The treated portion emerged in undamaged condition while the untreated paper fell apart. No dissolution or blurring of ink was observed in the treated portion of the newsprint.
EXAMPLE 2 Strength Testing of Paper The strength of treated paper was compared to that of an untreated paper. Strips of paper (20 pound White Wove, Gilbert, Inc., Menasha, WI) about 1 inch wide, 8 inches long, and 0.004 inches thick, were immersed for 10 minutes in solutions with varying concentrations of fluoropolymer. The strips were removed and dried, leaving a fluoropolymer deposit in the paper. The tensile strengths of the strips were measured using a model 1122 Instron test machine (Instron Corp., Canton, MA) and ASTM Method D 828 procedures (the test bars were held in grips with a separation of 5 inches, and the cross head speed was 2 inches/minute). The fluoropolymer treatment increased the strength of the paper. The results are shown in Table 1 below, as well as in Figure 1.
