A method for the treatment of a textile fiber to reduce the amount of UV light passing through a fabric produced from said treated fiber comprising treating a textile fiber with 0.1 to 6.0% by weight on the fiber, of a UV absorber of the formula (1) ##STR1## wherein A is the radical of a UV absorber, B is the radical of a UV absorber or is a water-solubilizing group and X is F or Cl, and textile fabrics and articles of clothing produced from said fabrics. Fabrics prepared from the treated fibers are useful in making clothing which provides protection against UV radiation for skin which is covered by the clothing, especially lightweight summer clothing.
A method of improving the tear resistance of a textile fiber material, which comprises treating the textile fiber material with 0.1 to 6.0% based on the weight of the textile fiber material, of a compound of the formula (1) ##STR7## wherein A is the radical of a UV absorber, B is the radical of a UV absorber and X is F or Cl,
A method of reducing the amount of UV light passing through a textile fiber material, which comprises treating the textile fiber material with 0.1 to 6.0% based on the weight of the textile fiber material, of a compound of the formula (1) ##STR8## wherein A is the radical of a UV absorber, B is the radical of a UV absorber and X is F or Cl, with the proviso that at least one of A and B is substituted by at least one SO.sub.3 H or COOH group or a salt thereof which is bonded directly to an aromatic ring.
