<p><P>PROBLEM TO BE SOLVED: To efficiently produce a nonwoven fabric of a synthetic fiber which has high additional value from a cloth-shaped fiber waste in which various kinds of materials are mixed. <P>SOLUTION: The kinds of materials constituting a cloth-shaped fiber waste are identified from the cloth-shaped fiber waste by using a plastic-distinguishing machine constituted by a near infrared spectrophotometer. The fiber containing 10 wt.% or more of cellulose-containing fiber included in the cloth-shaped waste is specified, selected and removed. The remaining fiber waste from which the fiber containing 10 wt.% or more of cellulose-containing fiber is selected and removed is recovered and finished to a nonwoven fabric so as to be recycled as the nonwoven fabric of the synthetic fiber which is a material for industry. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
