<p>The present invention relates to a method for producing a needle-punched non-woven fabric by recycling waste cut pieces of aramid fabrics. According to the present invention, a needle-punched non-woven fabric is produced by recycling waste cut pieces of aramid fabrics from a weaving process using an aramid fabric mainly used as high strength, high heat resistant industrial material. Furthermore, according to the present invention, the waste cut pieces of aramid fabrics are introduced into a scutcher without slip and entanglement, and high strength waste aramid is uniformly dispersed in the non-woven fabric, and it is possible to produce a non-woven fabric with a simple process and at lower costs than the existing products.</p> |
