摘要： Provided is an environmentally friendly process for producing a sheet-shaped material having both an elegant, napped appearance and a soft texture, which qualities have not been achieved concurrently, and also exhibiting good abrasion resistance. The process of the present invention for producing a sheet-shaped material includes the successive steps of (a) adding a polyvinyl alcohol having a degree of saponification of 98% or more and a degree of polymerization of 800 to 3,500 to a fibrous substrate in an amount of 0.1 to 50% by mass relative to the total mass of fibers in the fibrous substrate; (b) adding a waterborne polyurethane to the fibrous substrate with the added polyvinyl alcohol; and (c) removing the polyvinyl alcohol from the fibrous substrate with the added waterborne polyurethane.

摘要： An electret filter media, and mask, that is made of a nonwoven web of thermoplastic microfibers. The thermoplastic microfibers are of substantially the same composition, are nonconductive, and have an effective fiber diameter less than about 15 micrometers. The nonwoven web also has sufficient unpolarized trapped charge to exhibit an initial filtration quality factor of at least 0.31 when measured under the DOP Penetration and Pressure Drop Test.

摘要： A method for treating proteinaceous materials that contain disulfide or polysulfide bonds to improve their performance at high relative humidity and when wet. The method comprises annealing the fabric at a temperature in the range of from 70.degree. C. to 160.degree. C. at a regain of between 10% and 25% for a period greater than about 10 minutes wherein the fabric is annealed in the presence of a gas which enhances the disulfide interchange reaction. A further embodiment of the invention comprises annealing the fabric at a temperature in the range of from 70.degree. C. to 160.degree. C. to a regain of between 10% and 25% for a period greater than 10 minutes wherein the fabric has at least in part been treated with a liquid which enhances the disulfide interchange reaction. The present method is particularly applicable to keratinous materials such as for example wool, wool with reduced crystallinity, mohair, regenerated protein, or mixtures thereof.

摘要： A fabric such as a knitted wool or wool mixture is treated by the application of a crabbing agent together with a hygroscopic substance. The fabric is then dried, sheared and moistened before passing through a decatizing apparatus in which the crabbing agent, reactivated during the moistening stage, reacts within the fabric fibers to render the changes produced during decatizing permanent.
