What is PLA fiber? (Polylactic Acid Fibers)

What is PLA Fiber (Polylactic Acid Fibers)

PLA Fiber are made from PLA (PolyLactic Acid). also PLA is made from corn. The fiber products are highly smooth and completely non-irritating to the skin, also they are 100% biodegradable and compostable. The fiber forming substance is a lactic acid polymer in which at least 85% by weight are lactic acid ester units derived from naturally occuring sugars (sugar beets and corn).

Although compostable, polylactic acid is quite durable in most applications. Infact, PLA does not readily degrade unless it is exposed to high humidity and elevated temperatures (≥ 60°C) which results in rapid decomposition of the fiber. Thus, for most applications, its durability is acceptable or good. The tensile strength of PLA fibers is comparable to those of polyester fibers. However, PLA has a low Tg of only 55 – 60°C and thus, is less heat resistant than polyester (PET). It is also more flammable and less abrasion resistant.

PLA is the only melt-processable natural based thermoplastic that can be melt spun into filaments which is often the most ecconomic and convenient method. However, the fiber can be also spun by a number of other methods. Dying can be accomplished with disperse or direct dyes using conventional processes when avoiding (strong) alkaline conditions.

Applications of PLA Fiber (Polylactic Acid Fibers)

PLA is fully biodgradable and biocompatible1,2 which makes this fiber attractive for medical applications like wound dressing. The fiber is also useful as an eco- and people-friendly alternative to existing textile fibers for industrial and consumer apparel applications.

Major applications for PLA fibers and non-wovens include, clothing and furnishings such as drapes, upholstery and covers. Some exciting potential applications include household and industrial wipes, diapers, feminine hygiene products, disposable garments, and UV resistant fabrics for exterior use (awnings, ground cover, etc.) among others .

  • Denier: 4.5 D | 6.0 D | 9.0 D | 15 D
  • Conventional color: Raw white | green | blue.
  • PLA fiber are more hydrophilic than PET
  • Low flammability and smoke generation characteristics.
  • 100% biodegradable and compostable. PLA Fiber are made from PLA (PolyLactic Acid), also PLA is made from corn. the fiber products look and feel just like regular fiber, but they are 100% biodegradable and compostable. Corn is a renewable resource which makes corn fiber much more sustainable than regular fiber. Did you know that regular fiber is made from petroleum . PLA Fiber is however biologically degradable, when subjected to the right conditions. It is therefore very well suited for waste treatment through composting. It will also improve the compost quality by increasing the C/N ratio in the organic waste. Because lactic acid is made out of natural sugar resources, which are in turn made by photosynthesis out of CO 2 in plants, the material can be regarded as “CO2-neutral” and therefore renewable.
