Kraft process. Process used in paper industry to extract lignin from pulp using sodium hydroxide and sodium sulfide. 

P-Xylosidases are being used commonly in paper industry for complete degradation of xylans. The enzymes used in the synthesis of xylose-containing compounds have also been reported. For example, Eneyskaya et al. (50) have used />-nitrophenyl P-D-xylopyranosides (XyiPpNP) as a donor and a 3-xylosidase ixom Aspergillus sp. in the synthesis of several 31,4-D-xylooli-gosaccharides as P-xylanase substrates. 

Cationic starches have numerous applications in paper industry, in textiles, as flocculating agents, in cosmetics, adhesives, etc. 

A number of copolymers of vinylidene chloride are used in practice. Copolymers with acrylonitrile are used in low flammability fibers (modacrylic fibers). These fibers begin to lose weight when heated at 285-308° C due to dehydrohalogenation [41] but do not ignite easily. A tercopolymer butadiene-styrene-vinylidene chloride is used in fabrics industry and in paper industry. Other copolymers include PVC/PVDC, used for fibers and for films with low permeability to gases and water vapors (barrier films), etc. 

Poly(imines) are polymers that contain in their backbone amino nitrogens connected by single bonds to carbon atoms. Some of these polymers have a simple structure like poly(ethylene imine) or [-CH2-CH2-NH-]n. The polymer is obtained from the polymerization of aziridine, typically generating a mix of linear and branched macromolecules with about 25% primary amine groups, 50% secondary amine groups, and 25% tertiary amine groups. The polymer is used in paper industry and for various other purposes that make use of its anionic character [1]. 

Chemical composition, particle size, particle shape, specific gravity, surface area, refractive index, brightness, absorptivity, and wettability are the most important criteria used in selecting a filler for the paper industry. For further reading, a recent monograph on the use of fillers in paper industry is an excellent source of practical information. ... 

In paper industry jargon, chlorine dioxide bleaching is ECF bleaching (elemental-chlorine-free) and bleaching with oxygen species TCF bleaching (totally-chlorine-free).

Chemical modification of starch makes it suitable for many applications in the food products (e.g., as gelling agents, encapsulating agents, thickeners) and the non-food industry (e.g., as wet-end additives, sizing agents, coating binders, and adhesives in paper industry as textile sizes in cosmetic formulations) [46]. 

These data show that it would require 100 million bubbles to remove 1 g of SDS from the solution However, pollutants generally are found in concentrations less than 1 mg/L. Thus, one would need about 100,000 bubbles to remove 1 mg of SDS/L of water solution. This is a rather low number of bubbles. This seems to be a very large number. Since bubbles can be easily produced at very fast rates (ca. 100-1000 bubbles/min), this is not a big hindrance. Consequently, any kind of other SAS (such as pollutants in industry) can be thus removed by foaming. For example, in the recycle process in paper industry, ink pollutant molecules are removed by bubble foam technology. It is also important to consider that if an impurity in water was surface-active molecule, then this procedure can be used to purify water.
