A latex paint composition comprises (a) a polymer having interpolymerized units that comprise units derived from styrene, methyl styrene, vinyl, or combinations thereof and units derived from one or more acrylates, methacrylates, acrylonitrile, or combinations thereof, (b) hiding pigment, (c) non-cellulosic thickener, and (d) at least about 0.05 weight per volume percent fluorochemical acrylic polymer additive comprising (1) at least one perfluoroalkyl moiety selected from the group consisting of heptafluoropropanesulfonamido, nonafluorobutanesulfonamido, undecafluoropentanesulfonamido, and tridecafluorohexanesulfonamido moieties and (2) at least one polyoxyalkylene block comprising at least one alkyleneoxy moiety. Also, methods for providing paint coatings with such compositions.

Latex paint compositions and coatings

A high solids spin finish composition is provided that can be readily applied to synthetic fibers during the fiber-making process. The spin finish composition comprises a hydrocarbon surfactant and a fluorochemical emulsion.

High solids spin finish composition comprising a hydrocarbon surfactant and a fluorochemical emulsion

A soil-resistant spin finish composition based on select derivitized polyethers is provided that can be applied to a fiber at the earliest stages of spinning, can remain on the fiber through the entire manufacturing process, and can be left on the fiber in the final article of commerce. The spin finish composition provides excellent fiber lubrication during high-speed spin processing, yet is sufficiently soil resistant to negate the need for scouring the final fiber construction, even absent the presence of additional coatings or agents.

Soil-resistant spin finish compositions

A low melting, high solids spin finish composition is provided that can be readily applied to synthetic fibers during the fiber-making process. The spin finish solids, which make up at least about 70% by weight of the spin finish composition, comprise nonionic hydrocarbon surfactant components, such as polyoxyalkylenes, which have a <HLB> value of from about 2 to 13 and a melting point within the range of about 25&deg; C. to about 140&deg; C. In some embodiments, the spin finish composition also includes select fluorochemicals.

Process of drawing fibers

A high solids spin finish composition is provided which includes a nonionic hydrocarbon surfactant and which has a <FLB> value of less than 11 and a <HLB> value within the range of about 2 to 13.

Process of drawing fibers through the use of a spin finish composition having a hydrocarbon sufactant, a repellent fluorochemical, and a fluorochemical compatibilizer

A shelf-stable spin finish composition, and a method for making the same, is provided. The spin finish composition has a &lt;HLB&gt; value within the range of about 2 to 13 and comprises a hydrocarbon surfactant and a total weight percent of water t, wherein t&lt;k, and wherein k is the weight percent of water required to render the composition visibly turbid.

The spin finish solids, which make up at least about 70% by weight of the spin finish composition, comprise nonionic hydrocarbon surfactant components, such as polyoxyalkylenes, which have a &lt;HLB&gt; value of from about 2 to 13 and a melting point within the range of about 25.degree. C. to about 140.degree. C. In some embodiments, the spin finish composition also includes select fluorochemicals.
