What are the core advantages of polylactic acid fiber
source：www.kingcharmgroup.com | Release time：2025-12-231. Renewable+fully degradable, environmentally friendly ceiling (core unique advantage)
The raw materials are sourced from renewable plant starches such as corn, straw, and cassava, and do not rely on petroleum resources, reducing the consumption of fossil fuels from the source; After being discarded, it can be completely degraded into carbon dioxide and water in natural environments such as soil and compost, with no residue or white pollution. It meets the requirements of carbon neutrality and environmental protection policies, solves the pain point of traditional chemical fibers being difficult to degrade, and is a good "environmentally friendly fiber".
2. Skin friendly and non irritating, suitable for close fitting scenes
The fiber surface is smooth and delicate, without chemical irritation, and does not contain harmful residues such as formaldehyde and aromatic amines. The touch is similar to cotton fiber, and it fits snugly without sweating or itching; At the same time, it has better moisture absorption and breathability than polyester, which can quickly dissipate sweat and keep the skin dry, especially suitable for people with high requirements for clothing safety such as sensitive skin and infants.
3. Outstanding natural functionality, no need for additional chemical finishing
Comes with multiple practical functions, no need to add chemical additives, safer and healthier:
Natural antibacterial properties: The fiber itself contains lactic acid, which can prevent the growth of common bacteria such as Escherichia coli and Staphylococcus aureus. Clothing and home textiles are less prone to mold and produce odors, and can maintain cleanliness for a long time;
UV resistance: It has excellent UV resistance, with a UPF value of up to 30+, which can block UV damage. It can be directly used for sun protection clothing and outdoor fabrics without the need for additional UV finishing;
Anti static: It has better anti-static properties than polyester and nylon, and the fabric is less prone to dust and pilling, making it easier to wear and easier to maintain.
4. Physical properties suitable for textile processing, balancing aesthetics and durability
The dry breaking strength is 3.0~4.5cN/dtex, which is close to polyester. The fabric is stiff and stylish, not easy to wrinkle, and the pattern stability is better than cotton and linen; Good elasticity recovery, not easily deformed after repeated wearing; Strong spinnability, capable of spinning short and long fibers, and can also be blended with fibers such as cotton, linen, spandex, etc., taking into account the advantages of different fibers and meeting diverse fabric needs.
5. Lightweight and easy to maintain, suitable for daily use
The fiber density is low, and the fabric made of it is light, thin, and soft. It has no weight-bearing effect when making T-shirts, shirts, sportswear, and other clothing; At the same time, it has good stain resistance, and stains are not easily attached. It is easy to dry after washing and does not require high temperature ironing (low temperature ironing is sufficient), making daily maintenance convenient.
