STUDY OF MECHANICAL PROPERTIES AND CHEMISTRY OF THE COCONUT FIBER GREEN FOR USE IN FOOTWEAR

This study characterized the green coconut fiber species Cocus nucifera L. disposed in the city of Francisco Morato - Sao Paulo, to check the viability of employed of application in the footwear sector. The fibers was made a maceration biological, traction and optical microscopy tests were run to evaluate the surface structure of the fiber, the breaking force, the elongation at break and the breaking tenacity. The mechanical tests carried out showed great potential for use in shoe soloed and insoles that require structures to be reinforced

CHEMICAL COMPOSITION AND MECHANICAL PROPERTIES OF FIBER COCUS NUCIFERA L. FOR USE IN FOOTWEAR INDUSTRY

This study aimed to investigate the main chemical compositions and mechanical properties of green coconut fiber from fruits dropped in the town of Francisco Morato - São Paulo to verify the feasibility of use in the footwear sector. In tropical countries like Brazil there is a large consumption of coconut water and green, this raises a problem concerning the final destination of the fruit. Give an applicability for these residues help minimize the environmental problem. We conducted a biological maceration into the fibers, tensile testing and optical microscopy. Was researched literature on the chemical composition of the fibers. The results showed that coconut fibers have the potential to be used as raw material in the construction of portions of shoes, especially at high lignin content present in the walls of the fibers, which provides good flexibility, protection against attack by microorganisms and are renewable

Qualidade pós-colheita da alface hidropônica em ambiente protegido sob malhas termorefletoras e negra

Considerando que a duração da exposição, a qualidade e intensidade de luz afetam as características de qualidade das hortaliças folhosas, conduziu-se um experimento, em ambiente protegido, com o objetivo de avaliar a qualidade pós-colheita da alface hidropônica, sob os efeitos das malhas de sombreamento, com diferentes percentagens de atenuação da radiação solar. O delineamento experimental foi o de blocos casualizados, no esquema fatorial 2 x 5, com três repetições, sendo os tratamentos constituídos por quatro malhas termorefletoras (40; 50; 60 e 70% de sombreamento) e uma testemunha, com malha negra 50%. Em cada parcela, representada por um sistema hidropônico individual, foi cultivada a alface (cv. Olinda, Crespa), sendo avaliada sua qualidade por ocasião da colheita e após quatro dias de armazenamento refrigerado (7,6 ± 1ºC e 27 ± 5 % UR). Observou-se que o excesso de sombreamento, ocasionado pelas malhas termorefletoras 60 e 70% e malha negra 50%, comprometeram a aparência da alface. As plantas submetidas ao sombreamento com a malha termorefletora 40% apresentaram menor perda de massa, ao final de quatro dias de armazenamento. Os graus de sombreamento ocasionados pelas malhas termorefletoras e pela malha negra não influenciaram nos teores de ácido cítrico, sólidos solúveis, vitamina C e clorofila total da alface
