Manufacturing and Stab-Resisting Properties of Compound Fabric Reinforced Using Recycled Nonwoven Selvages

Abstract

Nowadays, the development of science and technology are rapidly, relatively, wastes brought more and more problems. Because the waste produced by the textile production accounts for 5% of total rubbish quantity, so how to reduce the pollution of the selvage wastes and how to effective treatment waste is the present primary task in the course of developing. This research is mainly to use two layers of the 7.0d polyester (PET) nonwoven as the base cloth of the upper strata and lower strata, and the selvage wastes of the PP are layered between them. The polyester nonwoven and selvage wastes combine by needle punching and thermal bonding than the nonwoven/ selvage wastes compound fabrics are formed. By this production, we can reduce waste quantity of selvage to achieve the environmental protection purpose, and increase the strength of the compound fabric. The results show when the weight of base cloth is 150 g/m2, the content of selvage waste in the compound fabric is 10%, temperature of thermal bonding is 220 °C, the liner velocity of the thermal compress roll is 0.5 m/min and the density of needle punching is 400 needles/cm2, the compound fabric has best mechanical properties. The stab resistance and the application of the compound fabric in geotextile are evaluated by test according to ASTM D4632 and ASTM D4533 standard.
