PLA Spunbond Nonwoven Fabric

Product Description

PLA spunbond nonwoven fabric offers high tensile strength, excellent breathability, and complete biodegradability. It is environmentally safe and decomposes naturally into water and carbon dioxide under composting conditions.

With a soft texture and stable structure, it is suitable for face mask outer layers, disposable medical gowns, hygiene products, and eco-friendly packaging materials. Compared with conventional PP spunbond, PLA spunbond has similar mechanical properties but is biobased and compostable, meeting the growing demand for green and sustainable materials.

Production Process

1. PLA Pellet Melting:
   Plant-based PLA pellets are melted and extruded into fine continuous filaments.

2. Web Formation:
   The filaments are laid randomly or directionally on a moving belt to form a uniform web.

3. Thermal Bonding:
   The web is thermally bonded through heat and pressure to create a durable and cohesive fabric.

4. Finishing and Rolling:
   The finished fabric is cooled, treated (if needed), and rolled for packaging and shipment.

This spunbond process ensures uniform fiber distribution, excellent strength, and consistent fabric quality.

FAQ

Q1: What is the difference between PLA and PP spunbond fabric?
A1: PLA is made from renewable plant-based materials and is biodegradable, while PP (polypropylene) is petroleum-based and non-degradable.

Q2: How long does PLA spunbond take to degrade?
A2: Under industrial composting conditions, it typically degrades within 6–12 months into CO₂ and water.

Q3: Is PLA spunbond suitable for skin-contact applications?
A3: Yes, it’s non-toxic, hypoallergenic, and skin-friendly, perfect for hygiene and medical products.

Q4: Can it be laminated with other biodegradable layers?
A4: Yes, PLA spunbond can be combined with PLA meltblown or film layers for breathable composites.

Q5: Do you offer customization for weight, width, and color?
A5: Yes, all parameters can be customized to meet customer requirements.
