Naturally Colored Cotton

The Northeastern region of Brazil comprises the Caatinga biome (900,000 km²) part of which is a semiarid region with rainfed and irrigated production systems. Among the successful breeding programs are cashew and cotton. The first led to a substantial increase in nut production in Ceará, Rio Grande do Norte and Piauí and the second bred a naturally colored cotton fiber, now processed in small clothing industries in Paraiba, exporting to 11 countries. In the lower-middle São Francisco valley, the previously grown onion was replaced by improved varieties, on 90% of the production area, and by industrial tomato, introduced by research in 1972, which came to be used on more than 80% of the area at the time. The participation of the private sector and continuity of breeding programs were crucial for the success. More examples of success are expected with the establishment of postgraduate courses in Agricultural Sciences in the Semiarid region.

The naturally colored cotton fiber was treated by sodium hydroxide solution with different concentrations and temperatures.The surface morphology,crystalline structure, mechanical properties and color feature value of fiber after treatment were tested by SEM,XRD,electronic single fiber strength tester and Computer Color Matching meter.The results show that the longitudinal convolutions of the naturally colored cotton fiber treated by concentrated sodium hydroxide decreased or disappeared,and the fiber became nearly cylindrical or cylindrical.The crystallinity of fiber after treatment decreased,part of the celluloseⅠ changed into celluloseⅡ．The breaking strength and breaking elongation of fiber after treatment increased.The total color differences（ΔE） and value a*of fiber after treatment increased，to the contrary，value L* and value b* decreased，which leaded to that the color of fiber treated by alkali became darker．In addition,the treatment temperature had larger influence on the properties of fiber.

Main Component

Naturally colored cotton is a green textile material. To cultivate new colored cotton and improve its performance, we must first understand the types, composition, and formation mechanism of the pigments in colored cotton. This study aims to explore the composition and structure of cotton fiber pigments. Qualitative analyses of pigment extracts from brown cotton, green cotton, and white cotton fibers were carried out using ultraviolet spectroscopy, diagnostic agents, and liquid chromatography–mass spectrometry. The main component of cotton fiber pigments was flavonoids, and specific types of flavonoids were found in the pigments in brown cotton, green cotton, and white cotton fibers. Research on the composition of cotton fiber pigments can increase our understanding of colored cotton fibers and lay a foundation for the cultivation, planting, and development of colored cotton fibers, as well the identification of naturally colored cotton from dyed cotton.

ABSTRACT Naturally-colored cotton fiber has received attention from breeding programs in the semiarid region of northeastern Brazil due to an increased interest in its fibers. Therefore, this study aimed to select genotypes of colored cotton fiber for agronomic and technological fiber characteristics for the Brazilian semi-arid conditions. The experiment was carried out in two environments (Patos-PB and Apodi-RN) in Brazil during the 2016 growing season. The experimental design was in randomized blocks with four replications. Treatments consisted of eleven colored fiber genotypes and three controls (BRS Topázio, BRS Rubi, and BRS Verde). The following traits were assessed: seed cotton yield (SCY, kg ha-1), lint percentage (LP, %), lint length (LEN, mm), lint strength (STR, gf tex-1), and lint micronaire (MIC, µg in-1). The data were submitted to individual and joint variance analyses, and means were grouped by the Scott and Knott (1974) test at 0.05 probability. Genotypes showed variability in all traits, which allows genetic gains in subsequent cycles of selection. The genotypes BRS Topázio, CNPA 2002 10245, and CNPA 2002 10327 presented the best estimates for the assessed traits, thus they can be selected for future studies in cotton breeding programs in the semiarid region.

AbstractThis study aims to analyze the products of the catalytic pyrolysis of naturally colored cotton residues, type BRS (seeds from Brazil), called BRS-Verde, BRS-Rubi, BRS-Topázio and BRS-Jade. The energy characterization of biomass was evaluated through ultimate and proximate analysis, higher heating value, cellulose, hemicellulose and lignin content, thermogravimetric analysis and apparent density. Analytical pyrolysis was performed at 500 °C in an analytical pyrolyzer from CDS Analytical connected to a gas chromatograph coupled to the mass spectrometer (GC/MS). The pyrolysis vapors were reformed at 300 and 500 °C through thermal and catalytic cracking with zeolites (ZSM-5 and HZSM-5). It has been noticed that pyrolysis vapor reforming at 500 °C promoted partial deoxygenation and cracking reactions, while the catalytic reforming showed better results for the product deoxygenation. The catalyst reforming of pyrolysis products, especially using HZSM-5 at 500 °C, promoted the formation of monoaromatics such as benzene, toluene, xylene and styrene, which are important precursors of polymers, solvents and biofuels. The main influence on the yields of these aromatic products is due to the catalytic activity of ZSM-5 favored by increased temperature that promotes cracking reactions due expanded zeolites channels.
