Polylactic acid (PLA) resin fiber grade material

Polylactic acid (PLA) resin fiber grade material is a specialized thermoplastic biopolymer tailored explicitly for fiber production, emerging as a transformative solution in the global shift toward sustainable materials. Derived entirely from renewable biomass resources such as corn starch, sugarcane, or cassava, it stands in stark contrast to traditional petroleum-based fiber raw materials, addressing the pressing environmental concerns of resource depletion and plastic pollution.
Origins and Development: The development of fiber-grade PLA resin stems from the growing demand for eco-friendly alternatives in textile, medical, and industrial sectors. Unlike many degradable natural fibers, it possesses the unique advantage of being melt-processable, bridging the gap between the functional properties of synthetic fibers and the sustainability of natural ones.
Material Nature: This resin exists primarily in pellet form, designed to integrate seamlessly with conventional fiber spinning and stretching equipment—eliminating the need for costly machinery overhauls for manufacturers transitioning to green materials.

Insoluble in water, easily soluble in hot alkaline solution
Non-toxic, non-irritating
Good biocompatibility
Biodegradable and absorbable
High strength
Plasticity processing molding

Medical and health field: Disposable sanitary cloths, surgical gowns, protective gowns, sterilized wrapping cloths, etc.
Daily life field: Home decoration, clothes nonwoven, textile

100% Bio-based and Compostable: Under industrial or home composting conditions, it completely decomposes into carbon dioxide and water within 90–180 days, leaving no toxic residues or microplastics behind.
Dual Benefit of Natural and Synthetic Fibers: Combines the comfort and biodegradability of natural fibers (e.g., cotton, hemp) with the mechanical strength and processability of synthetic fibers, creating a versatile material for multiple industries.
Human and Environmental Safety: Free of harmful substances such as phthalates and bisphenol A (BPA), it is non-toxic, skin-friendly, and compliant with FDA food contact standards. Its weak acidic nature is gentle on human skin, reducing irritation risks.
Value-added Functionalities: Naturally exhibits antibacterial, anti-mildew, and UV resistance properties—features rarely found in other biodegradable plastics, enhancing the durability and safety of end products.
Cost-effective Processing: Easy to process with high efficiency, minimizing production downtime and lowering manufacturing costs for businesses adopting sustainable practices.

Textile & Apparel: Ideal for spinning pure or blended yarns (with cotton, silk, viscose, or Lyocell) to produce fabrics for underwear, outerwear, and activewear. Its breathability and smoothness enhance wearer comfort.
Nonwovens: Widely used in manufacturing non-woven fabrics for disposable hygiene products (e.g., face masks, diapers), medical dressings, and industrial wipes—leveraging its antibacterial and biocompatible properties.
Home Textiles: Suitable for bed linens, cushions, and curtains, thanks to its mold-resistant, flame-retardant, and hypoallergenic characteristics that improve indoor living quality.
Packaging Materials: Processed into biodegradable non-woven bags, food packaging liners, and garment packaging. Its moisture-proof and lightweight properties protect items while aligning with eco-friendly packaging trends.

In the field of sustainable biopolymers and fiber materials, customers interested in fiber-grade PLA resin often inquire about complementary and similar products. These include modified PLA resin (high-heat resistant and low-heat resistant variants) optimized for specific fiber processing needs, PLA filament and staple fibers for direct textile production, PLA/PBAT blend resins that enhance flexibility for non-woven and packaging applications, and biodegradable PLA non-woven fabrics ready for end-product manufacturing. Additionally, bio-based thermoplastic elastomers paired with PLA resin are popular for applications requiring improved stretchability.
