3-Dimensional fibrous mats is open structure with sinuously looped and self-bonded macronlaments and they have been used for the purpose of erosion control, embankment protection. Canal construction and sports complex antral so forth. Since transverse strength and porosity of the fibrous mats are very important properties, many observations on these increase have been studied. In the present work, 3-Dimensional fibrous mats are made with continuous melt-spun polypropylene(PP) macrofilament for different processing parameters with a newly designed melt-spinning system. The characteristics of these process are found that PP macrofilaments are spun toward the pattern roller with frequency roller to increase the strength of fibrous mats and to form interlooped filaments adhering to each other at random overlapping points of intersection. And we evaluate the erect of processing collditions i. e., spinning distance(b/w nozzle and pattern roller). take-up speed and frequency speed on the structure and properties of mats.
