According to literature survey, many works have dealt with studying the effect of some bags on biological, chemical and physical quality of date fruit. In this study, RSM (response surface methodology) modeling and desirability function methods were applied and compared to predict the overall quality of cover date bunch samples. Five nonwoven bagging product are selected to be examined that are used for the first time on date palm sector. The results proved that a high quality of bagging product could be obtained in optimal conditions. Using the influential parameters and optimized conditions as fabric weight, thickness, air permeability, resistance to water penetration, tear strength and tensile strength, the results indicate that the cover date bunch remains influenced especially by the air permeability properties and tensile strength as well. Desirability function has been proven to be effective to achieve ideal design performance. The results show that the highest desirability reached is 0.6.However, the efficient approaches to identify the relevant parameters and the relation between different quality features and parameters have not been completely studied. To overcome the gap, a combined method including desirability function and response surface methodology (RSM) was proposed. Referring to previous works, desirability function allows a high level of flexibility over classical mathematical methods in evaluating and defining global quality. According to the analytical results obtained, the desirability function method gives a more accurate prediction than the RSM one. [ABSTRACT FROM AUTHOR]

Effect of fiber treatment on the strain We can conclude from figures presented previously that all composite tensile properties are improved when increasing the fiber weight ratio and also after the chemical treatment of the fibers used for. Fiber weight ratio of composites HT

The effect of fiber treatment, reinforcement structure and fiber weight ratio on the flexural properties of Typha-polyester composites was studied. A unsaturated polyester matrix reinforced with a mixture of Typha Leaf fibers (M.Ty.LF) and a nonwoven Typha Leaf fibers (NW.Ty.LF) was fabricated with various treatments conditions (sea water, alkali and combined treatment) and fiber weight ratio. Results show that alkali treatment and combined process provided better mechanical properties of composites in comparison with fiber treated by sea water. The fiber weight ratio influenced the flexural properties of composites. Indeed, a maximum value of flexural strength (69.8 MPa) and flexural modulus (6.16 GPa) was observed for 12.6 % fiber weight ratio. SEM photographs revealed a different fracture surface between Typha Leaf fibers reinforced polyester composites. [ABSTRACT FROM AUTHOR]
