Abstract
The nonwoven waste coming from textile industry takes up 5% of the total waste amount, so to recycle and to regenerate the waste is the prior obligation of the factory to reduce the waste. Nonwoven selvages waste can be buried or burnt but these two methods result in environmental pollution. This research proposes to reuse these waste nonwoven selvages effectively, and is designed as follows. Each piece of thermal-bonding material comprised a sandwich structure, with two layers of 7.0d PET matrices enclosing a layer of PP nonwoven selvage and nylon geogrid. After needle-punching and thermal-pressing, it forms a laminate structure of PET nonwoven/ PP selvage/ PET nonwoven in that it decreases the impact by the environmental pollution and protects the environment ultimately. In addition, thermal-bonding reinforces the mechanical properties of the composite fabric structure. The results of the experiment suggest the optimum manufacture parameters (selvage content: 10 %; thermal-bonding temperature: 220°C; needle-punching density: 400 needles/ cm2). The composite fabric undergoes the burst strength test and permeable coefficient measurement, evaluating its applications in geotextile filed.
