Extraction Of Cornhusk Fibres For Textile Usages

Development of sanitary napkins using corn husk fibres in absorbent layer – an exploratory study

“…Table 2 below gives the values of various physico-chemical properties of extracted corn husk fibres [15].…”

“…An extensive study on extracting corn husk fibres using alkali, enzyme and bleaching treatments was conducted by Jain et al The authors found the extracted fibres suitable for use in developing variety of products such as yarn, rope and hand-made mats [14]. Considering the multifarious applications of corn husk fibres, as reported by various researchers, corn husk fibres were extracted and characterized for their properties [15]. The fibres extracted from corn husk were found to have high water retention; hence their suitability for use in sanitary napkins was explored.…”

Response Surface Optimization of Corn Husk Fiber Mercerization Using NaOH

“…Biomass weight loss and Lignin are affected by retting time, retting concentration and weight of the corn husk biomass [26]. Lignin is the bond (glue) that exists in fibrous or woody material which are often affected by alkaline solution.…”

Situación socioeconómica de la producción y comercialización de totomoxtle en el Estado de Puebla, México

“…Another product generated from maize and for which there is demand in national and international markets is "totomoxtle" or bracts that cover the ear (cornhusks). The importance of totomoxtle lies, among other aspects, in that it contributes photosynthates for the development of maize grains (Kang et al, 1986), since maximal photosynthetic rates are similar between the maize leaf and cornhusk when expressed on a chlorophyll basis (Penguelly et al, 2011); it protects the ear against damage from field insects (Demissie et al, 2008); it is useful in the preparation of tamales and to make handcrafts (Long and Villarreal, 1998); its fiber is similar in quality to the one produced by cotton and linen, conferring potential for textile and industrial use (Reddy and Yang, 2005a;2005b), quality that was corroborated through the evaluation of the physicochemical properties of totomoxtle, which showed its potential for several textile applications (Jain et al, 2017); it has potential to be used in construction materials, furniture, decorative articles, and other fields, since flame-delaying compounds have been extracted from totomoxtle fibers (Lihua et al, 2017); and even though the levels of anthocyanins in purple maize vary significantly between different parts of the plant, it was found that there are regions of totomoxtle where their content is high, which is why an additional use of totomoxtle could be as a source of antioxidants (Chun-Ying et al, 2008), since it also has higher levels of phenols, flavonoids and total ketosteroids, so it can be used as potential candidate for the prevention of diseases related to many byproducts of human metabolism (Dong et al, 2014). These and other uses of totomoxtle could revalue maize production in Mexico and the world.…”

“…Otro producto que se genera a partir del maíz y del que existe demanda en mercados nacionales e internacionales es el totomoxtle (hojas de maíz) o brácteas que cubren a la mazorca. La importancia del totomoxtle radica entre otros aspectos en que aporta fotosintatos para el desarrollo de los granos en maíz (Kang et al, 1986), pues la tasa fotosintética máxima del totomoxtle expresada en base a clorofila es similar a la de las hojas del maíz (Penguelly et al, 2011); protege a la mazorca contra daños de insectos en campo (Demissie et al, 2008); es útil para la preparación de tamales y elaboración de artesanías (Long y Villarreal, 1998); su fibra es similar en calidad a la que producen el algodón y el lino, lo cual le confiere potencial para uso textil e industrial (Reddy y Yang, 2005a;2005b), cualidad que se corroboró a través de la evaluación de las propiedades fisicoquímicas del totomoxtle, lo cual demostró su potencial para varias aplicaciones textiles (Jain et al, 2017); tiene potencial para utilizarse en materiales para construcción, muebles, artículos decorativos y otros campos, ya que a partir de fibras extraídas del totomoxtle se han aislado compuestos retardantes de flama (Lihua et al, 2017); y aun cuando los niveles de antocianinas en maíz morado varían en forma significativa entre las distintas partes de la planta, se encontró que hay regiones del totomoxtle en donde su contenido es elevado, por lo que un uso adicional del totomoxtle podría ser como fuente de antioxidantes (Chun-Ying et al, 2008), ya que posee además altos niveles de fenoles, flavonoides y cetosteroides totales, por lo que puede ser utilizado como candidato potencial para la prevención de enfermedades relacionadas con varios sub productos del metabolismo humano (Dong et al, 2014). Estos y otros usos del totomoxtle, podrían revalorizar la producción del maíz en México y el mundo.…”
