What is the barrier performance of polylactic acid fiber
2025-08-12The barrier performance of polylactic acid (PLA) fiber is a key consideration in its applications in packaging, medical, textile and other fields. Overall, its barrier performance shows a certain degree of barrier to gases such as oxygen and carbon dioxide, but poor barrier to water vapor. The specific performance and influencing factors are as follows:
-
Which industries will use more polyester fibers
2025-08-06Polyester fibers have been widely used in various industries such as textiles, clothing, transportation, industrial manufacturing, and construction due to their excellent properties. Here are some industries that use polyester fibers more frequently:
-
What are the advantages of composite spun fibers
2025-07-29Composite spun fibers are fibers made by special spinning processes (such as composite spinning machines) from two or more polymers with different properties. The fibers exhibit a distribution structure of two or more components (such as skin core type, parallel type, sea island type, etc.) inside or on the surface. This structural design combines the advantages of multiple materials, with perform
-
What are the applications of polyester fibers in the field of packaging materials
2025-07-22Polyester fiber (commonly known as "polyester") is widely used in the field of packaging materials due to its high strength, tear resistance, chemical corrosion resistance, and good dimensional stability, covering multiple scenarios from basic packaging to functional packaging. The following are its main application directions and characteristics:
