Experiments in Textile and Fiber Chemistry focuses on selected experiments in the chemistry of fibrous polymers and ancillary materials designed primarily for undergraduate students in technical colleges, polytechnics, and universities.
The book first reviews the determination of 'available' chlorine in sodium hypochlorite solution, hardness of water, and estimation of iron in water. The text also ponders on the determination of the saponification and iodine values of oils, use of the pH meter, and use of pH indicators and acid-base titrations.
The publication examines the determination of the nitrogen content of organic substances by the Kjeldahl method; separation of amino acids by paper chromatography and paper electrophoresis; and thin layer chromatography. Identification of N-terminal amino acids by the 'Dansyl' method; supercontraction of wool; rendering wool resistant to acid dyeing; effect of breaking disulfide cross-links in wool; and the formation of lanthionine linkages in wool are discussed.
The text is a valuable reference for textile and fiber experts interested in the chemistry of fibrous polymers and ancillary materials.
