The application of nonwoven fabrics for mattress springs is mainly as follows:

Spring Wrapping and Protection

• Independent support and anti-interference: In pocketed coil mattresses, nonwoven fabrics wrap each spring individually, allowing the springs to operate independently and reducing mutual interference. When one person turns over or gets up, it will not cause much impact on the other person, ensuring a quiet sleeping environment.
• Preventing friction and noise: It can prevent direct friction between springs and between springs and other mattress components, reducing the creaking noise caused by friction during use and prolonging the service life of the springs.
• Protecting springs from damage: It avoids the erosion of springs by external factors such as moisture and dust, prevents springs from rusting, and maintains the stable performance of the springs.

Mattress Structure Support

• Buffering and support: The nonwoven fabric located above the springs can buffer the contact points of the metal spring units and provide additional support for the human body, making sleepers feel more comfortable. It is a relatively cheap alternative layer.
• Enhancing stability: Thick nonwoven textile materials at the bottom of the mattress can provide additional support and stability for the spring units of anti-flip mattresses, ensuring that the mattress does not move or flip easily during use.

Improving Comfort

• Moisture absorption and sweat wicking: Some soft polyester nonwoven materials have the advantages of moisture absorption and sweat wicking, which can absorb and dissipate the sweat excreted by the human body, keep the sleeping environment dry, and make sleepers feel more comfortable.
• Temperature regulation: Some nonwoven fabrics also have the function of temperature regulation. For example, the surface of the Coolmax pocketed coil mattress has a cool feeling, making it feel cooler to sleep on in summer.

Meeting Safety and Functional Requirements

• Flame retardancy: Nonwoven fabrics can be subjected to flame retardant treatment to make them flame retardant, helping mattresses pass relevant fire safety standard tests, and improving the safety of mattresses.
• Anti-slip: Anti-slip designs, such as anti-slip dots, can be added to the nonwoven fabric at the bottom of the mattress to increase the friction between the mattress and the bed frame or the ground, preventing the mattress from sliding during use.

Facilitating Processing and Assembly

• Simplifying production processes: Using appropriate non-woven fabrics to cover mattress springs can simplify the production process of mattresses. For example, using a nonwoven bag with a rectangular shape and a zipper opening on the side to cover the mattress spring frame eliminates the need for circumferential ultrasonic welding, saves the time for covering and processing spring mattresses, and improves processing efficiency.
• Facilitating installation and disassembly: For some mattresses that need to be assembled or disassembled, the use of nonwoven fabrics makes the installation and disassembly of springs more convenient, facilitating the maintenance and replacement of springs. For example, in pocketed coil mattresses, when a spring has a problem, it can be replaced by simply opening the nonwoven bag.
