As a new type of green and environmentally friendly fiber, PLA fiber is different from traditional cellulose fiber and chemical fiber, but it has the advantages of these two fibers: first, its raw materials and cellulose fibers are from natural plants, and many It is an annual green plant, including corn, beet and cassava, etc., mainly using plant sugar; secondly, PLA fiber has the same superior fiber properties and processing performance as chemical fiber, with various effective functions and relatively stable melting point, and at the same time according to needs. It can also be made into a kind of functional PLA fiber for special requirements; the biggest feature is that it can be 100% degraded into carbon dioxide and water in the state of landfill compost, and the entire processing and use process of PLA fiber is low energy consumption, environmentally friendly and recyclable Yes, it effectively reduces carbon emissions and is environmentally friendly.
(1) Features: high strength, fast moisture permeability, good gloss, certain UV resistance, good resilience, fluffy and warm, good flame retardancy, no allergy, low odor residue, etc.
(2) Varieties and uses: Fiber grade PLA: chip spinning
●Lactide: Melt direct spinning
●Long fiber: FDY, DTY, POY
A. FDY: Fully drawn yarn. It has nothing to do with the production process, but it is now widely circulated. It is used as the code name of the one-step spinning and drawing process. Low-speed spinning, high-speed drawing and winding can be used. This process is completed on a spinning and drawing combined machine. This production line has low production cost, stable product quality, less wool breakage and good dyeing uniformity. FDY fiber is straight and is completed by one-step textile drawing.
B. DTY: Draw texturing yarn stretched textured yarn, also known as polyester low elastic yarn, is the finished yarn after continuous or simultaneous stretching and deformation processing on one machine. DTY fiber is crimped and deformed by false twisting Gives silk a fluffy effect after processing.
C. POY: Preoriented yarn. When the high-belt spinning speed is 3000-3600m/min, pre-oriented yarn can be obtained. At high winding speed, the fibers have a certain degree of orientation, and the structure is stable.
●Staple fiber: for spinning, non-woven, and filling
●Medical field: sutures, etc.
