復合性能好 雙組份PE/PP和PE/PET為皮芯式結(jié)構(gòu)，PE具有較低熔點，作為表層材料，可在較底溫度下與其它材料復合。PP和PET相對熔點較高、強力高，作為芯層可保證無防布的強力要求。皮與芯層的熔融溫度相差30—130度，溫差范圍較廣，易于生產(chǎn)過程控制。 復合加工方法可采用流延法、超聲波、熱復合等多種復合方法。 主要應用：婦嬰衛(wèi)生產(chǎn)品，***產(chǎn)品，復合包裝材料、服裝敷料等等。 Good laminating properties: Bicomponent PE/PP and PE/PET nonwovens are sheath-core structure. The component of the sheath is polyethylene. It has lower melting point. The component of the core is polypropylene or polyester. Just because these two materials h***e higher melting point. So, it maintains the high tensile strength and also has good laminating properties. The melting point of the sheath and core difference between 30 to 130 degrees centigrade. Hence, the production process is easy to control. Composite processing is including cast, ultrasonic and thermal compound method and others. Application: feminine and infant hygienic products, medical products, composite packaging materials, wound addressing and so on....
