PLA Mother Yarn - Biodegradable Fiber for Splitting into Fine Monofilaments

PLA Mother Yarn is a specialized industrial multifilament yarn engineered for high-efficiency splitting into finer monofilaments. Made from 100% biodegradable PLA derived from renewable plant resources, this biodegradable yarn offers exceptional production efficiency and outstanding environmental benefits. Available in 30D/10f, each yarn bundle contains 10 individual filaments that can be split into finer monofilaments. As a premium PLA yarn and biodegradable fiber, it combines natural skin-friendliness, antibacterial activity, moisture-wicking, and compostability. Widely used in apparel, baby wear, bedding, home textiles, and pet products.

Product Description

1. Product Overview

PLA Mother Yarn is a specialized industrial multifilament yarn engineered for high-speed splitting into finer monofilaments. It is made from polylactic acid (PLA)—a biodegradable thermoplastic polyester derived 100% from renewable plant resources such as corn starch and sugarcane—combining exceptional production efficiency with outstanding environmental benefits.

PLA, also known as polylactide fiber or PLA fiber, is produced through lactic acid fermentation from biomass cellulose (such as straw) and subsequent polymerization. As a next-generation green fiber material, PLA offers a sustainable alternative to petroleum-based synthetic fibers and plastics, actively contributing to carbon neutrality and reducing white pollution.

2. What Is Mother Yarn?

Mother yarn is a specialized multifilament yarn designed for subsequent "yarn splitting" processing. Unlike standard yarns, mother yarn consists of multiple filaments bundled together in a single strand. During downstream processing, these bundled filaments are split apart through mechanical splitting technology to produce finer monofilaments. This innovative approach dramatically improves production efficiency compared to traditional direct monofilament spinning. Our PLA Mother Yarn is supplied in 30D/10f—each bundle contains 10 filaments, and after splitting, each monofilament achieves a fineness of approximately 3D.

3. Key Performance Benefits

·Superior splitting performance: Produced using high-speed spinning equipment with excellent splitting properties. At warping speeds of 60 m/min, breakage frequency is less than 3 times per 100 meters. Production efficiency reaches 5-8 times that of traditional monofilament processes.

·High strength & low cohesion: High tensile strength with reliable durability; low cohesion ensures smooth and consistent splitting with no gel spots or defects.

·Naturally skin-friendly & safe: The fiber's mild acidity mimics that of human skin, making it non-irritating and hypoallergenic, with inherent antibacterial and anti-mite properties. Its hydrolysis product (lactic acid) is harmless to humans.

·Superior comfort: Excellent drape and a silky smooth hand feel; moisture-wicking and breathability outperform cotton and linen. Low moisture regain, low static, and low odor retention.

·Durability & protection: Good tensile strength, pilling resistance, flame retardancy, and UV resistance.

·Eco-friendly & biodegradable: As a biodegradable yarn, it fully decomposes into water and

CO₂under industrial composting conditions, leaving no harmful residues.
