1. Manufacturing Process

The production of needle-punched nonwoven master rolls involves several precise steps that ensure quality and consistency.

1. Fiber Preparation

• Fibers such as polyester, polypropylene, or natural fibers are selected based on the desired properties.
• These fibers are processed and blended to achieve uniformity.

2. Fiber Web Formation

• The blended fibers are spread into a web using air-laid or carding techniques.
• The web’s thickness and density are adjusted depending on the intended use.

3. Needle Punching

• High-speed needles pierce the fiber web, mechanically interlocking the fibers.
• This process increases the material’s strength and durability without the need for adhesives.

4. Post-Treatment

• Additional treatments, such as heat setting, calendaring, or lamination, enhance specific properties like smoothness, waterproofing, or thermal resistance.

Step	Description	Purpose
Fiber Preparation	Selecting and blending fibers	Ensures uniformity and quality
Web Formation	Creating a uniform fiber sheet	Determines thickness and density
Needle Punching	Interlocking fibers mechanically	Increases strength and durability
Post-Treatment	Enhancing specific properties	Improves functionality
