A fluorinated compound comprising: (i) a fluorochemical oligomeric portion comprising an aliphatic backbone comprising polymerized (meth)acrylate monomeric units, each having a perfluorinated terminal C4-C6 aliphatic group, and an organic residue obtained by removing a hydrogen atom from a functionalized chain transfer agent, wherein: the polymerized (meth)acrylate units are present in a molar ratio of at least 6:1 relative to the functionalized chain transfer agent; and the (meth)acrylate units comprise 0-30 mole-% acrylate units and 70-100 mole-% methacrylate units; (ii) a fluorine-free hydrocarbon moiety; (iii) a di-, tri-, or polymeric isocyanate-derived linking group; and (iv) a group that imparts a durable property when the compound is applied to a fibrous substrate.

The present invention provides fluorinated compounds as well as dispersions of the fluorinated compounds. The fluorinated compounds described herein, in some embodiments, can be applied substrates such as textiles, including carpet and other floor coverings.

Invention is directed to a method of extruding an omni-phobic filament comprising: extruding a co-polymer filament having a first polymer at a core having generally a circular cross-section, and a second polymer disposed at a perimeter of the core wherein the second polymer is dissolvable; creating channels disposed at the perimeter of the core by dissolving the second polymer; creating trapezoidal cross-section features having a distal angle less than 70, a top edge greater than a side length and a bottom length less than the side length; and adding nano-sized particles to at least one of the top edge and one or more sides or any combination thereof.

A water- and oil-repellent composition for a nonwoven fabric, which includes (1) a fluorine-containing water- and oil-repellent agent and (2) a sizing agent and is water-based, can impart good alcohol repellency, water pressure resistance, and antistatic properties to an object to be treated, such as a nonwoven fabric. The water- and oil-repellent composition for a nonwoven fabric does not contain a carbodiimide compound and may contain at least 20 wt % of water with respect to the water- and oil-repellent composition. The active ingredient of the sizing agent may include an alkylketene dimer and/or an alkenylketene dimer. The water- and oil-repellent composition may further contain an antistatic agent and a penetrant. A treated substrate may be a nonwoven fabric.

The present invention provides fluorinated compounds as well as dispersions of the fluorinated compounds. The fluorinated compounds described herein, in some embodiments, can be applied substrates such as textiles, including carpet and other floor coverings.

Disclosed is a nonwoven fabric formed from (i) a nonwoven fabric substrate and (ii) a fluorine-containing polymer adhering to the nonwoven fabric substrate, wherein the fluorine-containing polymer contains:

(a) repeating units formed from a fluorine-containing monomer which is alpha-chloro acrylate or alpha-chloro acrylamide containing a fluoroalkyl group, and
(b) repeating units formed from a halogenated olefin monomer, and
the fluorine-containing polymer is free from repeating units formed from a (meth)acrylate containing a linear or branched hydrocarbon group having at least 18 carbon atoms.

The present disclosure relates to methods for producing water repellent textile substrates and products thereof. The methods can be conducted without the use of perfluorocarbons.

The invention relates to a process for preparing a cyclic siloxane copolymer, a water repellent composition and the use for treating porous substrates like concrete, especially reinforced concrete.

A high performance fabric comprised of a plurality of high-performance fibers coated with an anti-microbial compound and an anti-stain compound, where the high-performance fibers are polyester microfibers for comfort. The anti-microbial compound is a wash resistant non-organic antibacterial or a non-organic microbicidal. The anti-stain compound is hydrophobic or superhydrophobic, preferably polytetrafluoroethylene or silicone. Optionally, additional flame resistant fibers are interwoven with the high-performance fibers to increase flame resistance.

The present invention provides fluorinated compounds as well as dispersions of the fluorinated compounds. The fluorinated compounds described herein, in some embodiments, can be applied substrates such as textiles, including carpet and other floor coverings.
