3. Key Characteristics
1. Definition and Composition
PP spunbond non woven fabric, also known as polypropylene spunbond fabric, is a type of non woven fabric made from 100% polypropylene fibers. Unlike traditional fabrics that are woven by yarn, non woven fabrics are made by bonding or interlocking fibers together mechanically, thermally, or chemically. The resulting fabric has a unique structure with excellent tensile strength and durability.
2. Manufacturing Process
The manufacturing process of PP spunbond non woven fabric involves several stages, each playing a crucial role in achieving the desired characteristics. The main steps include:
a) Extrusion: The process begins with extruding molten polypropylene through spinnerets to obtain long continuous filaments.
b) Spinning: The filaments are then stretched to enhance their molecular orientation and alignment, leading to improved strength and stability.
c) Web Formation: These stretched filaments are randomly laid onto a moving belt, forming a web-like structure.
d) Bonding: Heat and pressure are applied to bond the filaments together. This can be done through thermal bonding (using heated calender rolls), mechanical bonding (needle punching), or chemical bonding (using adhesives).
3. Key Characteristics
PP spunbond non woven fabric possesses numerous beneficial characteristics that make it an ideal choice for diverse applications:
a) Lightweight: The fabric is lightweight and breathable, ensuring comfort even in prolonged use.
b) High Strength: Despite its lightweight nature, PP spunbond non woven fabric has remarkable tensile strength, enabling it to withstand heavy loads and resist tearing.
c) Moisture Resistance: The hydrophobic nature of polypropylene fibers makes the fabric highly resistant to moisture, keeping it dry and suitable for various uses.
d) Chemical Resistance: PP spunbond non woven fabric exhibits excellent resistance to various chemicals, making it suitable for use in harsh environments.
e) Eco-Friendliness: As a synthetic fabric, PP spunbond non woven fabric can be recycled, contributing to sustainability efforts.
