Question

The process flow of non-woven fabric manufacturing is:
A. web laying
B. fibre preparation
C. mechanical bonding
D. web formation
E. finishing Choose the correct answer from the options given below :

• A. A, B, C, D, E
• B. B, D, A, E, C
• C. B, D, C, A, E
• D. B, D, A, C, E

Hint:

In non-wovens, "Bonding" is the critical step that turns a loose pile of fluff into a stable fabric. It always happens after the web is laid but before final finishing.

Answer 1

The Correct Option is D

Concept: Non-woven manufacturing bypasses the traditional yarn-making stage, converting fibers directly into a fabric structure.

Step 1: Fiber and Web Preparation.
The process begins with B (Fibre preparation), involving opening and blending. These fibers are then processed to create a loose structure through D (Web formation), such as carding.

Step 2: Laying and Consolidation.
To achieve the desired weight and width, the web undergoes A (Web laying) (e.g., cross-lapping). Once the layers are placed, they must be joined together via C (Mechanical bonding), such as needle punching or hydroentanglement.

Step 3: Final Stage.
The last step is E (Finishing), which may include coating, dyeing, or heat setting to give the fabric its final properties.
