  • Method for the treatment of textile fibers
    Patent number: 5700394
    Abstract: 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.
