Leather synthetic/artificial

Formation of condensation structures is the reason for gelation of solutions of various natural and synthetic polymers. Gelation may be accompanied by conformational changes of macromolecules, which occur in the case of gelling of gelatin and other biopolymers, or in the course of chemical reactions. For instance, according to Vlodavets, partial acetalization of polyvinyl alcohol with formaldehyde in acidic medium under the conditions of supersaturation yields fibers of polyvinyl formals which further undergo coalescence and form a network with properties similar to those of leather (and artificial leather substitute).

Throughout human history a limited number of fibers provided the fabric used for clothing and other materials—wool, leather, cotton, flax, and silk. As early as 1664, Robert Hooke speculated that production of artificial silk was possible, but it took another two hundred years before synthetic fibers were produced. The production of synthetic fibers took place in two stages. The first stage, started in the last decades of the nineteenth century, involved chemical formulations employing cellulose as a raw material. Because the cellulose used in these fibers came from cotton or wood, the fibers... 

Uses n-Butyl alcohol is used extensively in a number of industries. For instance, it is used as a solvent in industries associated with the manufacture of paints, varnishes, synthetic resins, gums, pharmaceuticals, vegetable oils, dyes, and alkaloids. n-Butyl alcohol also finds use in the manufacture of artificial leather, rubber, and plastic cements, shellac, raincoats, perfumes, and photographic films. 

After the surface layer of the leather sample is peeled off, the sample can be observed under a microscope. The collagen fibres of leather differ in appearance from non-woven fabrics and from the uniform polymers of coating and lamination in the synthetic substitutes. However, some artificial leathers in the market do better than the real leather. It has been reported that some leather substitutes with super-microfibres of nylon, polyester and polypropylene can have similar views of cross-section under the microscope (Cheng, 1998). A combination of the bum test, the chemical test, the infrared spectroscopic analysis and/or the microscopic... 

OTHER COMMENTS used in the manufacture of lacquer, artificial leather, photographic films, plastics, and safety glass solvent for nitrocellulose, oils, fats, waxes, camphor, cellulose esters, fingernail polishes, resins, and lacquer stains synthetic flavoring ingredient used in producing banana, pear, pineapple and berry flavors. 

OTHER COMMENTS used as a pharmaceutical aid used as a synthetic flavoring substance useful in the manufacture of smokeless powder, photographic films, artificial leather, artificial silk, and perfumes applications as a solvent for nitrocellulose, varnishes, lacquers, and aeroplane dopes. 

OTHER COMMENTS used as a solvent for nitrocellulose, acetylcellulose, and many oils and resins also used in the manufacture of artificial leather other uses include paint remover compounds, lacquer solvents, and synthetic flavoring. 

Isopropyl ocetote is a wofer-whife pleosont-odored liquid with properties intermediote between ethyl and butyl acetates. It is miscible with most of the common organic solvents such os alcohols, ketones, esters, oils, hydrocarbons, etc., and it is a solvent for nitrocellulose, cellulose ocetate (of low viscosity) and a wide ronge of oils, fats, waxes, gums ond notural and synthetic resins. Like n-propyl ocetote, its solvent power for cellulose esters is increosed when lower aliphatic alcohols are added. It is largely used in the lacquer industry where its slow evaporation rate and blush resistance ore of importance. It is also used in the monufacture of plastics, artificial leather, dopes, films, cements, and in the recovery of acetic ocid from aqueous solutions.
