      復合噴絲板 Composite Spinneret for Melt Spinning
          發布時間: 2016-06-01 14:10    

      復合纖維是多組分纖維的一種,是針對人造纖維品種的術語。在同一根纖維截面上存在兩種或兩種以上不相混合的聚合物纖維,這種纖維稱復合纖維,利用復合纖維制造技術可以獲得兼有兩種聚合物特性的雙組分纖維。有并列型、皮芯型、海島型等復合纖維,纖維截面有圓形和異形。

      為了生產不同的復合纖維,我們為客戶設計不同種類的復合噴絲板。

      The?multicomponent fibers are fibers that combine at least two polymers having properties and/or different chemical compositions. The polymers are extruded together, and its relative position along the fiber length depends on factors like the geometry of orifícos the spinneret and the intrinsic properties of the polymer itself, including viscosity and molecular weight.
