Spunmelt non-woven fabric is a high-performance material produced through a combination of the spunbond and meltblown processes. It typically consists of multiple layers of non-woven fabric, often structured as SMS (Spunbond-Meltblown-Spunbond) or SMMS (Spunbond-Meltblown-Meltblown-Spunbond), with polypropylene (PP) being the most common polymer used.

Production Process: Spunmelt non-woven fabric is manufactured through a multi-step process:

1. Spunbond Layer: The outer layers are created by spinning molten polymer into continuous filaments, which are then laid into a web and bonded through heat or pressure.
2. Meltblown Layer: The middle layer(s) are produced by extruding molten polymer through a die with fine nozzles, resulting in a web of microfibers that are extremely fine and randomly distributed.
3. Lamination: These layers are then laminated together, creating a multi-layered fabric that combines the strengths of each individual layer.

Material: The primary material used is polypropylene (PP). It is chosen for its excellent balance of properties, including strength, durability, and resistance to chemicals. The layered structure allows for customization in terms of weight, thickness, and other properties, depending on the specific application.

Characteristics:

• High Filtration Efficiency: The meltblown layer provides superior filtration capability, making spunmelt fabric ideal for applications requiring barrier properties.
• Softness and Comfort: The spunbond layers contribute to a softer texture, making the fabric comfortable for use in direct contact with skin.
• Liquid and Particle Barrier: The multi-layer structure offers effective protection against liquids, particulates, and bacteria.
• Durability: The fabric has high tensile strength and tear resistance, ensuring long-lasting performance.
• Breathability: Despite its protective properties, the fabric remains breathable, making it suitable for extended wear.

Applications: Spunmelt non-woven fabric is widely used in industries that require high-performance materials:

• Medical Field: Used in surgical gowns, drapes, masks, and other protective garments due to its excellent barrier properties.
• Hygiene Products: Commonly used in diapers, sanitary napkins, and adult incontinence products because of its absorbency and comfort.
• Industrial Applications: Utilized in filters, protective covers, and industrial wipes, where both strength and filtration are required.
• Agriculture: Employed in crop covers and greenhouse shading due to its durability and breathability.

In summary, spunmelt non-woven fabric is a versatile and advanced material that offers a unique combination of strength, protection, and comfort, making it essential for a wide range of applications in medical, hygiene, industrial, and agricultural fields.
