Solution Overview
Problem
Conventional artificial turf made from polyethylene and polypropylene lacks high temperature resistance, wear resistance, anti-aging performance, grass fiber resilience, and trampling resistance, especially under high temperature conditions.
Innovation Solution
The use of artificial turf comprising a base mat with straight and curve fibers made from PA and PP materials, specifically PA6, PA66, PA1010, and PP types, with controlled cross-sectional shapes and deniers, and a method involving extrusion, drawing, and rolling to enhance temperature resistance and other performance metrics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If polyethylene and polypropylene are used as raw materials for artificial turf, then the manufacturing cost is reduced and processing is simplified, but the high temperature resistance deteriorates (can only withstand 95°C while surface temperature reaches 120°C or higher)
Solution Approach 1:
The patent changes the material parameter from conventional polyethylene/polypropylene to polyamide (PA6, PA66, PA1010, ST801), which fundamentally alters the temperature resistance property while maintaining manufacturability. This material substitution enables the turf to withstand temperatures of 120°C or higher, directly resolving the temperature resistance issue.
Solution Approach 2:
The patent employs composite material construction by combining polyamide fibers with specific cross-sectional shapes (diamond, olive, ribbed) and integrating them into a turf structure with base mat and backing layer. This composite approach achieves both high temperature resistance and improved mechanical properties simultaneously.
