    Abstract: Cationised silicic acid sols. (I) are claimed, contg. reaction prods. (II) of cpds. of formula RCONHC2H4OH (III) with 14-18 mols. ethylene oxide (EO) per mol. (III); R = 12-20C alkyl or alkenyl. Amt. of (II) is 15-40 wt.% w.r.t. SiO2 content; pref. (II) is the reaction prod. of oleic acid ethanolamide and 16 mols. EO. USE/ADVANTAGE - (I) are useful for providing textiles with a non-slip finish (claimed). (I) impart very good non-slip properties to textiles, esp. those based on viscose staple fibre, polynosics or other regenerated cellulose fibre, together with a very soft feel; addn. of (II) also improves the stability of the finishing bath. In an example, a mixt. of 16 pts. wt. 50% aq. soln. of Al2(OH)5Cl and 5 pts. wt. 50% aq. soln. of NaOAc.3H2O was treated with 60 pts.wt. 30% aq. silica sol (18-20 nm particles; adjusted to pH 4 with AcOH); half of this mixt. was stirred for 30 mins. at 60-70 deg.C, mixed with ethoxylated oleic acid mono-ethanolamide and stirred for 1.5 hrs. at 60-70 deg.C to give an opaque, colloidal soln. with pH 4.5 (I). Viscose clothing fabric with marked slip in the warp direction (100 g/m2) was finished in a batch contg. 50 g/l (I), squeezed out to 90% uptake and dried at 130 deg.C; the treated material had very good non-slip properties and a pleasant, soft feel; material treated with the unmodified half of the silica sol. had a rough, sandy feel.
