FILTER MATERIAL FOR PREPARING A BEVERAGE.

摘要

A filter material for removing chlorine from cold water used in preparing a human-consumable beverage having at least one layer of a mat of laid fibers (2) of cellulosic fibers (2) and synthetic textile fibers (2) and mixtures thereof. A synthetic hydrophilic, food-grade latex binder (3) deposited onto the fibers (2) within the mat in an amount sufficient to so bind the fibers (2) together within the mat that during a filtration of cold water through the mat no substantial amount of fibers (2) is displaced therefrom and in an amount insufficient to substantially reduce a gravity flow rate of cold water through the mat to less than about 0.3 liter per minute per 100 square centimeters of the mat. A water-insoluble chlorine adsorbent or absorbent solid powder (5) disposed on the binder (3) such that no more than 65 percent of the total outside surface area of the powder (5) is substantially contacted by the binder (3).
