Leather industry, application

Cutting mills, like shredders, are able to chop material which is too soft for milling examples of such materials include plastic, paper or leather. Industrial applications can be found in the paper and pulp industry, or in the recycling sector.

The most important industrial application of alkanesulfonates is the generation of the appropriate emulsions for polymerizing vinyl monomers, e.g., vinyl-chloride or styrene. Other uses are as textile and leather auxiliaries, formulating aids for plant protection agents, and fire-extinguishing foams. 

The application of membrane-separation processes in the treatment of wastewater of the leather industry can give a reduction of the environmental impact, a simplification of deaning-up procedures of aqueous effluents, an easy re-use of sludge, a decrease of disposal costs, and a saving of chemicals, water, and energy [22],... 

There are a number of industrial applications for paraffin sulphonates, such as EOR, leather processing and metal cleaning, which exploit their high solubility, chemical stability and electrolyte tolerance. 

The rapid growth of the pulp and paper industry following World War II coupled with a renewed scientific interest in utilization of bark and wood residues led to investigative programs on bark and wood tannins. The leather industry was continuing to decline in importance, so other alternatives were needed. One of these was replacement of phenol in whole or in part in phenol-formaldehyde adhesive formulations. This work progressed to the point where commercial quantities of polyphenolic extractives were made and sold for adhesive application. Excessive capacity and low petrochemically derived phenol prices in the 1960 s led to the demise of this effort in the United States (2,5). 

Polymers based on acrylic acid are highly hydrophilic and are utilized in different applications that include superadsorbent materials, flocculants and dispersants. Polyacrylates and their copolymers range from soft and flexible materials to hard plastics, applied in the production of coatings, paints, binders and adhesives. Their applications include the manufacture of cars e.g., coatings, upholsteries and adhesives) and the textile e.g., binders for fiberfill and nonwoven fabrics), paper and leather industries. Methyl acrylate is mainly utilized for copolymerization with acrylonitrile to improve the dyeability of fibres. 

EMEREST Glycerol Esters are based on fatty acids. In the leather and textile industries, they are used as components in lubricants, softeners, and dye carriers, and as co-emulslfiers for synthetic fiber spin finishes. Industrial applications include uses as lubricants, rust preventatives, and mold release agents. 

Sodium disulfite is produced by reacting sulfur dioxide with 50 to 70% sodium hydroxide in saturated sodium hydrogen sulfite solution. Sodium disulfite is isolated from the resulting suspension by centrifugation and dried. Applications Sodium disulfite is utilized in the photo-, paper, textile and leather industries and in water treatment. 

Applications Sodium hydrogen sulfide is mainly used in the paper industry, for ore flotation, in dye chemistry, in the leather industry for hair removal and in the synthesis of organic chemicals. The 1994 USA production of sodium hydrogen sulfide was ca. 100 10 t/a. 

Quantitywise the next most important application is for food conservation in the sectors of meat, dairy products and margarine. Of the numerous other uses the dye, detergent and leather industries and for softening of water (ion exchanger) are worthy of mention. 

Polymeric CrIn complexes with hydroxo and aqua ligands are the key species in the environmental chemistry of Cr,104,833 as well as in industrial applications, such as leather tanning834-836 or oil recovery (Section 4.6.5.10). Despite several decades of research (mainly by potentiometric methods), no unambiguous structural information on hydrolytic oligomers of Cr111 had been available prior to 1985.1...

Proteases are enzymes that break down protein molecules through peptide bond hydrolysis [1]. They are commercially employed in many industrial processes. In foods, proteases have two main applications in the processing of traditional food products and in the processing of new protein-based ingredients called functional foods [2]. Proteases are also used in other industrial segments such as leather industry, pharmaceutical, waste management, and the detergent industry. Currently, microbial proteases make up approximately 40% of total enzyme sales [3, 4]. 

Tensides have a wide range of practical applications particularly in the textile industry, and in the production and processing of plastics. They are also extensively used in the oil industry, in pulp and paper making, in foodstuff and leather industries, as well as in agriculture.
