| Abstract | ||||
| In this research an attempt has been made to modify the construction of a number of circular – knitted structures i.e. interlock, pile fabrics and single pique. This modification could be achieved by means of knowing the optimum constructional factors of each knitted structure such as polyester/cotton blend ratio, tightness factor and yarn twist multiplier. This research is concerned with the development and evaluation of the selected knitted structures for mechanical and dust – filtration applications with regard to specific work of rupture, busting pressure, rate of abrasion, filtration efficiency (7), pressure drop (AP), filter performance ((ϫ, filter efficiency per unit mass (7/M), specific cake resistance (K) and dust emission or out let concentration (Co). The mechanical and filtration properties of these structures are studied and compared with those of similar woven filter fabrics. Mathematical models describing these properties could be obtained, by using factorial design method, for predicting the knitted filter performance. By using the mathematical methods, it was found that the optimum fabric construction is recommended to be contained 100% crimped polyester fibers yarn,17.47 tightness factor (i.e. yarn count 20 Ne, loop length 0.31 cm) and 3αe twist multiplier with using interlock structure (Sample 2A) in the actual operating conditions were more efficient than conventional woven filters. | ||||
