Spunbonded Nonwovens Technological Industry
Joey 2017-03-01 15:20:14
Spunbond is the most important and widely used method in meltspinning nonwovens production. Applying the spinning principle of chemical fiber, the polymer turned into continuous filament by melting and spinning. The web formed by the filaments is bonded by the mechanical, chemic or thermbonding method. The spunbond process is short and efficient, having considerable cost advantage mass production. And the physics mechanical performance of the spunbonded nonwovens, such as the tensile, the elongation, and the tensile ratio of CD and MD is superior to other products. Spunbonded nonwovens products are applied to varies fields, such as apparel, decorative material, health care material, geotextile and material for agriculture, etc. So the PP spunbonded nonwovens products have extensive market.
Spunbonded nonwovens technological industry originated from the 1960′s. The early Spunbonded equipment cost and the energy consumption were high while the fiber denier, the web uniformity and product efficiency were not satisfying. Since the 1990′s, the world Spunbonded technology tended to the micro-fiber, multicomponent, multi-polymer spinning and the process combination. The spunbonded nonwoven have got a significant development taking the advantage of the increasing output and the reducing cost.
