What are the components of composite spun fibers
2025-11-25The core component of composite spun fibers is two or more polymers (resins) with different properties. In some scenarios, a small amount of functional additives may be added, which are fused through composite spinning technology to achieve complementary properties.
-
What is the insulation principle of polyester fiber
2025-11-18The core of the insulation principle of polyester fiber is to lock in static air and reduce heat transfer, using its structural characteristics to hinder heat loss and achieve insulation effect. Core insulation mechanism 1. Storage of still air: Polyester fibers themselves have a low density, and a large number of tiny gaps will form between fibers or inside fibers (such as hollow polyester fibe
