Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Wool fibers pretreated with chitosan, nano chitosan and neem/ chitosan composite and dyed with curcumin (curcuma long) and red onion peals natural dyes and saffron red and yellow mixture by using microwave heating method. The effect of chitosan/neem composite concentrations on color strength (K/S) was measured. Fastness properties and the color yield of the dye on wool fibers were evaluated. The morphologies structure of the untreated and pretreated wool fibers were examined by scanning electron microscopy (SEM). The results indicated that, wool fibers pretreated with the composite recorded higher color strength than the untreated fibers. The results indicated that color fastness to rubbing, washing and perspiration of all dyed wool fibers pretreated with the composite are higher than the untreated. The color fastness of dyed wool fibers pretreated are higher than the untreated. Scanning electron microscopy (SEM) indicated that the untreated wool fibers have a rough surface. The treated wool fibers were swelling compared to the untreated fibers. The diameter of the fibers increased and has smooth and even surfaces. 56 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -A renewed international interest has focused on natural dyes due to increased awareness of the environmental and health hazards associated with the use of synthetic dyes. there is an interest in the development of pigments obtained from natural sources. Natural dyes are mostly eco-friendly, biodegradable, less toxic, and less allergenic as compared to synthetic dyes. Recent research efforts are made to replace synthetic pigments with natural pigments from plant, animals and microorganisms. Some microbial pigments have numerous beneficial properties involving anticancer, anti-proliferative, immune-suppressive, antibiotic, biodegradability etc. Many microorganisms, including bacteria, fungi, yeast are employed for the industrial production of various pigments by using fermentation technology.The recent studies are interested in the pigment produced by microorganismssuchs as carotenoids, melanins, flavones, quinines, prodigiosin, and monascins. Many yeasts like Rhodotorula(pink), Yarrowialipolytica(brown), Cryptococcus (red) and Phaffiarhodozyma(carotenoids) are good source of microbial pigments. The pigment production by molds of Monascus group especially Monascuspurpureusand Monascusankafor use as a good color is well known for red color. The algae which produce pigments are Chlorococcum, Chlamydomonas, Chlorella, Hematococcusiand Sporangium. Another algae namely, Dunaliellasalinabelonging to class chlorophylaceae occur in marine environment and produces beta-carotene which can be used as food colorant. 72 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Fibras de lana pretratadas con quitosano, nano quitosano y compuesto de neem/quitosano y teñidas con curcumina (cúrcuma larga) y colorantes naturales de cáscaras de cebolla roja y mezcla de rojo y amarillo de azafrán utilizando el método de calentamiento por microondas. Se midió el efecto de las concentraciones de compuesto de quitosano/neem en la intensidad del color (K/S). Se evaluaron las propiedades de solidez y el rendimiento de color del tinte sobre fibras de lana. Se examinó la estructura morfológica de las fibras de lana sin tratar y pretratadas mediante microscopía electrónica de barrido (SEM). Los resultados indicaron que, las fibras de lana pretratadas con el compuesto registraron una mayor solidez del color que las fibras no tratadas. Los resultados indicaron que la solidez del color al frotamiento, al lavado y a la transpiración de todas las fibras de lana teñidas pretratadas con el compuesto es superior a la de las fibras no tratadas. La solidez del color de las fibras de lana teñidas pretratadas es superior a la de las no tratadas. La microscopía electrónica de barrido (SEM) indicó que las fibras de lana no tratadas tienen una superficie rugosa. Las fibras de lana tratadas se hincharon en comparación con las no tratadas. El diámetro de las fibras aumentó y tiene superficies lisas y uniformes. 52 pp. Spanisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Un renovado interés internacional se ha centrado en los tintes naturales debido a la mayor concienciación sobre los riesgos medioambientales y sanitarios asociados al uso de tintes sintéticos. Existe un interés por el desarrollo de pigmentos obtenidos a partir de fuentes naturales. Los tintes naturales son en su mayoría ecológicos, biodegradables, menos tóxicos y menos alergénicos en comparación con los tintes sintéticos. Recientemente se han realizado esfuerzos de investigación para sustituir los pigmentos sintéticos por pigmentos naturales procedentes de plantas, animales y microorganismos. Algunos pigmentos microbianos tienen numerosas propiedades beneficiosas como anticancerígenas, antiproliferativas, inmunosupresoras, antibióticas, biodegradables, etc. Muchos microorganismos, entre ellos bacterias, hongos y levaduras, se emplean para la producción industrial de diversos pigmentos mediante la tecnología de la fermentación. Los estudios recientes se interesan por los pigmentos producidos por microorganismos, como los carotenoides, las melaninas, las flavonas, las quininas, las prodigiosinas y las monascinas. Muchas levaduras como Rhodotorula (rosa), Yarrowialipolytica (marrón), Cryptococcus (rojo) y Phaffiarhodozyma (carotenoides) son una buena fuente de pigmentos microbianos. 72 pp. Spanisch.…
