Definitions

• the present invention relates to a fabric rinse composition containing a benztriazole UV absorber; and to a method of treating textiles with the composition, which method imparts to textile fiber material so treated, in addition to an excellent UV Protecting Factor (UPF) value, and other desirable properties.
• UPF UV Protecting Factor
• wavelengths 280-400 nm permits tanning of the epidermis.
• rays of wavelengths 280-320 nm (termed UV-B radiation), cause erythemas and skin burning which can inhibit skin tanning.
• UV-A radiation Radiation of wavelengths 320-400 nm (termed UV-A radiation) is known to induce skin tanning but can also cause skin damage, especially to sensitive skin which is exposed to sunlight for long periods. Examples of such damage include loss of skin elasticity and the appearance of wrinkles, promotion of the onset of erythemal reaction and the inducement of phototoxic or photoallergic reactions.
• Any effective protection of the skin from the damaging effects of undue exposure to sunlight clearly needs to include means for absorbing both UV-A and UV-B components of sunlight before they reach the skin surface.
• One aspect of the desire to increase the level of skin protection against sunlight has been the consideration of additional measures, over and above the direct protection of the skin. For example, consideration has been given to the provision of protection to skin covered by clothing and thus not directly exposed to sunlight.
• Such lightweight summer clothing normally has a density of less than 200 g/m and has a sun protection factor rating between 1.5 and 20, depending on the type of fibre from which the clothing is manufactured.
• the UPF rating of a sun protectant may be defined as the multiple of the time taken for the average person wearing the sun protectant to suffer sun burning under average exposure to sun. For example, if an average person would normally suffer sun burn after 30 minutes under standard exposure conditions, a sun protectant having an UPF rating of 5 would extend the period of protection from 30 minutes to 2 hours and 30 minutes. For people living in especially sunny climates, where mean sun burn times are minimal, e.g. only 15 minutes for an average fair-skinned person at the hottest time of the day, UPF ratings of about 20 are desired for lightweight clothing.
• UVA for use in a method for effecting an increase in the UPF value of a textile fiber material (often referred to as a "UV cutting" treatment method), has to take into account the fact that the treated textile fiber material must satisfy performance criteria in a wide range of areas, such as washfastness, lightfastness and tear resistance, apart from its UPF value.
