Artificial Turf Plasma Activation for Fiber-Backing Binding Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Artificial turfs have limited lifespans due to wear and tear from use and exposure to environmental factors, leading to the need for improved binding between fibers and backing layers to enhance durability and longevity.
Innovation Solution
A method involving a dielectric barrier discharge device with two electrodes, one encased in a dielectric, is used to plasma-activate the backside of a carrier mesh, followed by applying a backing layer, which increases the binding strength between the fibers and the backing layer, resulting in improved tuft bind and homogeneity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional manufacturing methods are used without plasma activation, then the manufacturing process is simple and energy consumption is low, but the binding strength between fibers and backing layer is weak
Solution Approach 1:
The patent applies dielectric barrier discharge plasma treatment to modify the surface properties of the carrier mesh backside. This changes the physical and chemical parameters of the surface, creating active sites that enhance binding strength between fibers and backing layer without requiring excessive energy input.
Solution Approach 2:
The patent replaces conventional mechanical or chemical binding methods with plasma activation. The dielectric barrier discharge creates a plasma field that activates the carrier mesh surface, enabling stronger bonding without mechanical fastening or extensive chemical treatments.
2Strength
If high energy plasma treatment is applied to enhance binding, then binding strength improves, but heat damage to polymer material increases
Solution Approach 1:
The patent introduces a dielectric barrier as an intermediary between the electrodes and the carrier mesh. This dielectric layer controls the plasma discharge, allowing activation of the carrier mesh surface while preventing direct contact between high-energy plasma and the polymer material, thus avoiding heat damage.
Solution Approach 2:
The dielectric barrier discharge allows precise control of plasma parameters (energy density, temperature, duration) to achieve surface activation without excessive heat input. By adjusting the dielectric properties and discharge conditions, the process activates the carrier mesh while maintaining polymer integrity.
3Strength
If dielectric barrier discharge with two electrodes is used, then binding strength and homogeneity improve, but device complexity increases
Solution Approach 1:
The patent divides the plasma treatment system into two separate electrodes with a dielectric barrier between them. This segmentation allows independent optimization of each electrode and the dielectric layer, enabling uniform plasma distribution across the carrier mesh surface while maintaining manageable device complexity.
Solution Approach 2:
The dielectric barrier serves as a mediator that distributes the plasma discharge uniformly across the carrier mesh surface. This intermediary component simplifies the overall device design by providing a controlled, homogeneous treatment field without requiring complex multi-point discharge systems.
