PLA Bicomponent Fiber 2D*38MM
Plant-Based Biodegradable Adhesive-Free Hot Air Bonding Fiber
Our 2D*38MM PLA bi-component sheath-core staple fiber is a high-performance eco-friendly thermal bonding fiber engineered for the fast-growing biodegradable nonwoven market. Manufactured through precision composite spinning technology with 100% polylactic acid, it replaces conventional petroleum-based low-melting fibers with a fully compostable, plant-derived solution while delivering reliable bonding strength and processing stability.
Unlike ordinary blended bonding systems, this fiber integrates both the binder and structural skeleton into a single filament. The outer sheath melts uniformly at 120-145°C, creating clean, consistent fiber-to-fiber bonds upon heating. The inner core remains solid at bonding temperature, preserving fiber morphology and providing mechanical strength to the final fabric.
The 2D fine denier and 38mm standard cut length represent the most widely adopted specification for general-purpose nonwoven production. The fiber cards smoothly, forms uniform webs and runs reliably on all standard high-speed nonwoven lines.
Wide Application Scenarios
Disposable Hygiene & Beauty: Biodegradable wet wipes, facial mask base cloth, cotton soft towel, sanitary napkin top sheet, baby diaper material
This bi-component staple fiber adopts a precision concentric sheath-core structure, with both layers made entirely of polylactic acid. The low-melting sheath softens and melts at 120-145°C to form a uniform physical bond between fibers, while the high-melting core maintains its fibrous shape as a stable structural skeleton. No chemical adhesives, binders or glues are required during production.
Fully Industrial Compostable, Zero Microplastic End-of-Life
Derived entirely from renewable plant starch through bio-fermentation, PLA is a true bio-based and biodegradable polymer. Under industrial composting conditions, the fiber biodegrades completely into carbon dioxide, water and organic biomass within 90-180 days, certified to EN 13432 and ASTM D6400 standards.
The sheath layer melts evenly and consistently across every single fiber, creating uniform bonding points throughout the web with no over-melting or under-bonding defects. The finished nonwoven fabric features excellent dimensional stability, ultra-low thermal shrinkage and consistent tensile strength.
2D Fine Denier + 38mm Standard Length, Wide Process Compatibility
The 2D fine denier delivers a soft, delicate hand feel and smooth fabric surface. The 38mm standard cut length is universally compatible with all mainstream carding, air-laid and nonwoven production lines worldwide without equipment modification.
High Purity Hygiene Grade, Skin-Friendly & Biocompatible
Produced in a closed clean workshop with food-contact grade PLA raw material, the fiber is free of heavy metals, fluorescent agents, plasticizers and harmful additives. It meets the safety requirements for medical dressings, infant hygiene products and food-contact materials.
Frequently Asked Questions
Q1: How does the bi-component PLA fiber bond fibers together? Is adhesive needed?
A1: It works through thermal bonding. The low-melting PLA sheath melts at 120-145°C and bonds adjacent fibers, while the high-melting core stays solid as skeleton. No chemical adhesive is needed at all.
Q2: Is this fiber really biodegradable? How long does it take to decompose?
A2: Yes, it is 100% PLA derived from renewable plants. Under industrial composting conditions (58-70°C, high humidity), it biodegrades completely within 90-180 days according to EN 13432 / ASTM D6400 standards, leaving no microplastic residue.
Q3: What temperature should I set for thermal bonding production?
A3: The recommended bonding temperature range is 120-145°C for the sheath to melt properly. Exact settings can be adjusted according to line speed, fabric weight and desired bonding strength.
Q4: Is 38mm length compatible with standard carding and air through bonding lines?
A4: Yes, 38mm is a standard general-purpose length fully compatible with all mainstream carding, air-laid and nonwoven bonding equipment. No equipment modification is required for direct use.
Q5: Can it be blended with other fibers like viscose, cotton or wood pulp?
A5: Absolutely. It blends excellently with natural fibers, cellulose fibers and wood pulp in any proportion. You can freely adjust the ratio to control fabric softness, absorbency, strength and cost.
Q6: Is it safe for direct skin contact and food contact applications?
A6: Yes. It is made of food-contact grade pure PLA without harmful additives, non-toxic, hypoallergenic and odorless. It is suitable for infant products, medical dressings, tea bags and food packaging.
Q7: Can I get free samples for bonding trial and production testing?
A7: Small test samples are provided free of charge for thermal bonding trial, web forming test and finished product performance evaluation.
