PLA NONWOVEN FABRIC

‌PLA nonwoven fabric‌ is a type of nonwoven fabric made from polylactic acid (PLA), a biodegradable polymer derived from renewable resources such as corn starch or sugar cane. PLA nonwoven fabric has several unique properties and applications that make it an attractive choice for various industries.

Properties

PLA nonwoven fabric is characterized: 

• ‌Biodegradability‌: PLA is a naturally degradable material, which makes the fabric environmentally friendly and suitable for applications where disposal is an issue.
• ‌Strength and Durability‌: Despite being biodegradable, PLA nonwoven fabric exhibits good mechanical properties, making it suitable for various industrial applications.
• ‌Controlled Wettability‌: The fabric can be engineered to have controllable wettability, which enhances its performance in oil/water separation and photo-catalysis degradation‌1.

Applications

PLA nonwoven fabric has a wide range of applications, including:

• ‌Environmental Applications‌: Its biodegradability makes it ideal for use in agriculture, horticulture, and landfill applications where environmental impact is a concern‌12.
• ‌Medical Applications‌: Due to its biocompatibility and biodegradability, PLA nonwoven fabric is used in surgical masks, wound dressings, and other medical devices‌2.
• ‌Packaging‌: It is used in packaging materials, particularly in single-use products where biodegradability is a plus‌2.

Production Process

PLA nonwoven fabric is produced through a variety of processes, including:

• ‌Meltblowing‌: This process involves melting PLA pellets and extruding them through small holes to form fibers, which are then collected and bonded together to form the fabric‌2.
• ‌Spunbonding‌: In this process, PLA fibers are spun and drawn into filaments, which are then bonded together to form the fabric‌2.

PLA nonwoven fabric offers a sustainable alternative to traditional nonwovens made from petrochemicals. Its unique properties and wide range of applications make it an attractive choice for various industries looking for environmentally friendly solutions.
