Polyethylene Mono-component Spunbond Nonwoven
Polyethylene spunbond nonwoven has gained great interest in recent years due to its unique haptics and properties. Its soft hand feel, smooth surface and high heat conductivity make it desirable for hygiene and medical products. However conventional polyethylene is known for their poor fiber spinnability which makes the nonwoven conversion process very challenging. With the recent technology breakthrough in polyethylene manufacturing process, a new polyethylene fiber grade resin has been developed for making monocomponent spunbond nonwoven. The improved spinnability significantly enhanced the productivity and reduced the rejection ratio. This presentation will focus on the performance of the polyethylene spunbond nonwoven. With the unique performance, it opens many new application areas in which polyethylene has not participated in before.
