Polyethylene terephthalate-based meltblown nonwoven fabric and process for producing the same |
摘要 |
Provided is a polyethylene terephthalate-based meltblown nonwoven fabric comprising a mixed polymer comprising 75 to 98% by weight of polyethylene terephthalate and 2 to 25% by weight of a polyolefin. The meltblown fabric has excellent thermal resistance, dimensional stability, strength and hand. Also provided is a process for producing a polyethylene terephthalate-based meltblown nonwoven fabric, which comprises melt blowing a mixed polymer comprising 75 to 98% by weight of polyethylene terephthalate and 2 to 25% by weight of a polyolefin. It is preferable that the melt blowing is conducted at a single orifice throughput of 0.2 to 1.0 g/min and under an air-jet pressure of 0.1 to 1.0 kg/cm2.
