Water-repellent organic fine particles having slip prevention effect

An organic fine particle for applying to a textile product comprising a polymer comprising a repeating unit formed from:

• (I) a hydrophobic monomer having one ethylenically unsaturated double bond and at least one branched or cyclic hydrocarbon group having 3 to 40 carbon atoms;
• (II) a crosslinkable monomer having at least two ethylenically unsaturated double bonds;
• and
• (III) a short-chain hydrocarbon-containing monomer having one ethylenically unsaturated double bond and at least one hydrocarbon group having 1 or 2 carbon atoms,
• wherein the molar ratio of the hydrophobic monomer (I)/the short-chain hydrocarbon group-containing monomer (III) is 3/97 to 55/45.

An anti-slip agent composition for textile, comprising:

• (A) the organic fine particle comprising a polymer comprising a repeating unit formed from:
• (I) a hydrophobic monomer having one ethylenically unsaturated double bond and at least one branched or cyclic hydrocarbon group having 3 to 40 carbon atoms;
• and
• (II) a crosslinkable monomer having at least two ethylenically unsaturated double bonds;
• and
• (B) an aqueous medium,
• wherein the slip resistance of the organic fine particle (A) on the substrate is 8.0 mm or less,
• wherein the slip resistance is measured in accordance with JIS-L-1096 B method as follows:
• A polyester fabric (white) treated with a water-repellent agent is cut into five test pieces of 10 cm×17 cm in each of a longitudinal direction and a lateral direction, the test piece is folded in half with the front face inside, and cut along the folding line, and the cut pieces are stitched together at 1 cm apart from the cut end with a normal sewing-machine needle #11, and a lockstitch seam system is employed, the number of seams per cm is set to 5, and a yarn of polyester filaments 78 dex×3 is used;
• a grab method is carried out using a tensile tester, and in the grab method, the test piece is clamped at a clamp distance of 7.62 cm, and a predetermined load (49.0 N (5 kgf)) is applied at a tension strength of 30 cm per minute, and thereafter, the test piece is removed from the clamp, and the maximum pore size (mm) in slippage of a load at which slacks in the vicinity of seams are eliminated after standing for 1 hour is measured.

A composition for treating textile, comprising:

• (A) the organic fine particle comprising a polymer comprising a repeating unit formed from:
• (I) a hydrophobic monomer having one ethylenically unsaturated double bond and at least one branched or cyclic hydrocarbon group having 3 to 40 carbon atoms;
• and
• (II) a crosslinkable monomer having at least two ethylenically unsaturated double bonds;
• and
• (B) an aqueous medium
• wherein the weight ratio of the binder resin (C)/the organic fine particle (A) is 55/45 to 90/10.
