Processing methods colorant application technology

Alcopops and spirit mixed drinks are gaming much popularity in the Western world, reaching impressive growth rates in recent years. Due to its specihc color and taste, beer cannot be directly used in such applications. Recently, NORIT process technology (NPT) has developed a method of beer decolorization that enables breweries to produce clear alcohol-water mixtures that can be used in premixes or alcopops (Source http //www.noritpt.nl). For beer-based drinks, the NPT membrane-based technology is able to produce a water-alcohol mixture with the taste and smell of beer. For premixes, alcopops, and comparable products, the taste and smeU can also be removed in an additional step, using activated carbon. 

Latexes (or latices) are widely used as nonwoven binders because they are versatile, can be easily applied, and are effective adhesives. The chemical composition of the monomer determines stiffness and softness properties, strength, water affinity, elasticity, and durability. The type and nature of functional side groups determine solvent resistance, adhesive characteristics, and cross-linking nature. The type and quantity of surfactant used influence the polymerization process and application method. The ability to incorporate additives such as colorants, water repellents, bacteriastats, flame retardants, wetting agents, and lubricants expands this versatility even further (see Latex Technology).
