No.9（2014）12.Manufacture of nonwoven fabrics from protection suits

Risa Nagao, Ichiro Enomoto, Kengo Kubotera

  In order to recycle the protection suits, nonwoven parts of protection suits were recarded using the opener and then the needle punched nonwoven fabrics were produced with the obtained recarded fiber. It was suggested that recarded fiber size could bechanged by controllingthe material feeding speed and the material tearing speed of the opener. Also recycle rate has beenincreased by adjusting the recarded fiber size. However, the tensile strength of polyester/recarded fiber nonwovens has decreased compared with the neat polyester nonwoven fabric. Therefore it is desirable that the recycled nonwoven fabrics will be used under the low-load condition.
