Mechanical Bonding in Non-woven Fabric Production
Web bonding is the process used to convert a web of fibres into a cohesive non-woven fabric. Mechanical bonding is one category of these techniques, relying on physical forces rather than heat or adhesives.
We need to identify which of the listed methods are types of mechanical bonding:
- A. Needle punching: This method uses barbed needles to mechanically entangle fibres, creating a fabric structure. This is a mechanical bonding process.
- B. Thermal bonding: This involves using heat to melt and fuse thermoplastic fibres. Since it relies on heat, it is not considered mechanical bonding.
- C. Hydroentanglement: This process uses high-pressure water jets to entangle fibres, which is a physical force. This is a mechanical bonding process.
- D. Stitch bonding: This technique uses sewing threads or yarns to mechanically stitch the fibres together, forming a fabric. This is a mechanical bonding process.
- E. Spray bonding: This method involves spraying a chemical binder or adhesive onto the fibre web. As it uses adhesives, it is not classified as mechanical bonding.
Correct Mechanical Bonding Techniques Identified
Based on the analysis, the types of mechanical bonding from the options provided are:
- Needle punching (A)
- Hydroentanglement (C)
- Stitch bonding (D)
Therefore, the correct combination representing mechanical bonding methods is A, C, and D.
