what is the absorption capacity of jute
Answers
Water absorption test is very important for determining degradability of the material in moist condition. The water absorption percentages of jute and pineapple fabric reinforced polyester composite specimens are shown in figure 8 for different soaking time. The water absorption percentages were increased with the increasing soaking time. The samples of jute fabric composite were exhibited higher water absorption than pineapple composite. This behavior was expected because the moisture regain of jute fibre is higher than the pineapple fibre. Besides, water can reside in composite due to other three reasons. Those are the lumen, the cell wall and the gaps between fibre and resin in the case of weak interface adhesion. The maximum water absorption (4.19%) was observed for the sample C at 60 minutes soaking time. It is well known that natural fibres are good water permeable as well as their composites. Hence, the water absorption characteristics of natural fibre composite is mainly fiber-controlled than the matrix
