Classification by Raw Material (Primary Classification Criterion)
Polypropylene Spunbond Nonwoven (PP Spunbond)
Characteristics: Lightweight (specific gravity 0.9), soft, waterproof & breathable, low cost, naturally degradable (decomposes in 90 days)<sup>59</sup>.
Applications: Shopping bags, packaging materials (over 60% of Chinese market sales), topsheet for hygiene products (e.g., diapers)<sup>310</sup>.
Process Features: Produced via melt extrusion → spinning → hot calendering reinforcement, suitable for mass production<sup>24</sup>.
Polyester Spunbond Nonwoven (PET Spunbond)
Characteristics: High strength, high temperature resistance (long-term use up to 260°C), UV resistant, abrasion resistant<sup>48</sup>.
Applications: Geotextiles, filter media, automotive interiors, base fabric for luggage (areas requiring high strength and weatherability)<sup>28</sup>.
Market Share: ~30% global PET spunbond share; over 40% used in China's industrial sector<sup>810</sup>.
Polyethylene Spunbond Nonwoven (PE Spunbond)
Characteristics: Good flexibility, chemical corrosion resistance, but lower strength than PET<sup>8</sup>.
Applications: Medical protective gown liners, agricultural mulch films (scenarios requiring flexibility and chemical stability)<sup>8</sup>.
Other Material Spunbond Fabrics
Include Nylon (Polyamide), Bio-based PLA, etc., accounting for less than 5% market share. Primarily used for specialty filtration or eco-friendly biodegradable products<sup>810</sup>.
