PLA Yarn And Thread

Rongdu is a professional manufacturer of PLA yarn and PLA thread.

Polylactic acid (PLA) is a biopolymer material produced through the fermentation of biomass sources like corn, beets, sugarcane, and straw cellulose, resulting in the polymerization of small molecules of lactic acid. The fibers made from PLA raw materials using spinning techniques are a novel and eco-friendly type of fiber.

PLA (polylactic acid) fibers have excellent biodegradability and can completely decompose into CO2 and H2O in the natural environment after being discarded. If PLA fibers are buried together with other organic waste, they will decompose within a few months.

PLA (polylactic acid) fibers are known for their gentle warmth, smoothness, and excellent elasticity. These PLA yarns and PLA threads offer remarkable biocompatibility, soft and skin-friendly characteristics, exceptional core absorption effect, and moisture-wicking properties. Processed products made from PLA fibers showcase a luxurious silk-like sheen, exceptional comfort, and excellent draping ability.

How PLA Fiber is Made of?


PLA fiber is made from polylactic acid, which is a biodegradable and bioactive thermoplastic derived from renewable resources such as corn starch or sugarcane. The process of making PLA fiber involves several steps:

1. Extraction of raw materials: Corn, wheat, beet, potato are harvested and processed to extract the starch, which is then fermented to produce lactic acid.

2. Polymerization: The lactic acid undergoes a process called polymerization, where it is chemically reacted to form long chains of polylactic acid molecules.

3. Spinning: The polylactic acid is then melted and extruded through spinnerets to form long, continuous fibers. These PLA fibers can be further processed to create different types of PLA fibers, such as filament fibers.

4. Drawing and stretching: The polylactide fibers are drawn and stretched to align the polymer chains and improve the strength and durability of the PLA fiber.

5. Finishing: The PLA fibers may undergo additional finishing processes such as dyeing, coating, or texturizing to enhance their properties and make them suitable for specific applications.
