What are the industrial applications of composite spun fibers
2025-10-21The core application of composite spun fibers in the industrial field relies on the advantage of "multi characteristic integration", adapting to high requirements for material functionality and durability in scenarios such as filtration, protection, and engineering construction, covering the following major directions:
-
How to adapt composite spun fibers to special needs
2025-10-14The core advantage of composite spun fibers (made by "co spinning multiple polymer raw materials" or "composite fibers with different structures", combining the characteristics of two or more single fibers) is "customizable performance" - by adjusting the raw material combination, structural design, and process parameters, it can be adapted to special demand scenarios such as high temperature, hig
-
What are the applications of polyester fiber in the medical industry
2025-10-10Polyester fiber, commonly known as "polyester", has extended its application in the medical industry from "basic auxiliary materials" to "functional medical supplies" due to its high strength, chemical corrosion resistance, easy disinfection, controllable cost and other characteristics. It can also be modified (such as antibacterial, anti-static, biocompatibility optimization) to meet the special
-
Briefly introduce the biodegradability of polylactic acid fibers
2025-09-29The core of the biodegradability of polylactic acid fibers is that their molecular structure can be decomposed by microorganisms into harmless carbon dioxide and water, and the degradation process depends on specific temperature, humidity, and microbial environment. The products have no burden on the natural environment.
-
What is the melting point of polylactic acid fiber
2025-09-23The melting point of polylactic acid fiber (PLA fiber, also known as polylactide fiber) is not a fixed value, mainly influenced by the stereoregularity of the raw material (left-handed/right-handed lactic acid ratio), the polymerization process (homopolymer/copolymer), and the fiber processing method. The melting point range of conventional commercial polylactic acid fiber is concentrated between
