Knitted Touch-Fastening Anti-Skidding Material
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional touch-fastener straps, such as hook-and-loop straps, face high manufacturing costs and difficulty in producing large width products, lack flexibility, and are not suitable for bonding to three-dimensional surfaces, limiting their application and efficiency.
Innovation Solution
A touch-fastening anti-skidding material is developed by knitting synthetic fibers/yarns of different characteristics or diameters to form a foundation layer with hollow or solid geometric shapes, providing resilience, air permeability, and flexibility, which can be easily shaped to fit three-dimensional configurations without the need for additional adhesives, and can be processed to form hooks for enhanced skidding resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional hook-and-loop straps are used, then touch-fastening function is achieved, but manufacturing cost increases and production of large width products becomes difficult
Solution Approach 1:
The anti-skidding material is divided into modular knitted panels that can be produced separately and then joined together. Each panel contains the complete functional structure with base layer, synthetic yarns, and hooks, allowing independent manufacturing and assembly. This segmentation enables both large-width products and cost-effective mass production while maintaining the touch-fastening function.
Solution Approach 2:
The patent replaces the conventional mechanical assembly of separate hook and loop bands with an integrated knitted structure where hooks are formed directly during the knitting process. This substitution eliminates complex mechanical fastening steps and reduces manufacturing cost while preserving the touch-fastening capability.
2Reliability
If conventional touch-fastener straps are used, then fastening function is achieved, but flexibility and ability to bond to three-dimensional surfaces is lost
Solution Approach 1:
The anti-skidding material uses a flexible knitted base layer with integrated synthetic yarns that can be conformally shaped to match three-dimensional surfaces. The knitted structure inherently provides flexibility and drapeability, allowing the material to adapt to complex geometries while maintaining its fastening function through the integrated hooks.
Solution Approach 2:
The patent varies the knitting parameters, yarn types, and hook formations to optimize both flexibility and fastening performance. By adjusting these parameters during the knitting process, the material can be tailored for specific three-dimensional applications while preserving the essential fastening capability.
3Productivity
If synthetic fibers and yarns are knitted together to form foundation layer, then mass production and flexibility are achieved, but additional adhesive layers are needed for bonding
Solution Approach 1:
The patent merges the base layer, synthetic yarns, and hook structures into a single integrated knitted component. This consolidation eliminates the need for separate adhesive layers and multiple assembly steps, reducing overall complexity while enabling efficient mass production of the complete anti-skidding material with inherent bonding capability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The material enables mass production of lightweight, air-permeable, and flexible anti-skidding solutions suitable for various applications, including felts, rugs, and loop cloth, with improved resistance against skidding and ability to bond to complex surfaces, reducing manufacturing costs and enhancing performance.
Implementation Method 1
The synthetic fibers/yarns are knitted in the foundation layer, all the synthetic yarns are tightly secured together without undesired separation off and thus additional adhesive layer applied to the bottom thereof for bonding purposes is not necessary.
Implementation Method 2
The touch-fastening material of the present invention may also be subjected to additional processing by passing through a tunnel-shape oven, in which ends of the fibers/yarns are melt and form hooks with rounded end.

AI summary
A touch-fastening anti-skidding material includes a knitted foundation layer and a plurality of synthetic yarns that is secured together by being collectively knitted in the foundation layer. The foundation layer is formed by knitting of pliable base yarns and synthetic yarns. The synthetic yarns are knitted in U-shaped loops and the base yarns are knitted between adjacent strands of the knitted synthetic yarns to make a large area cloth. The cloth may be in a planar form without hollow opening sections or it includes open sections to facilitate air permeability. The loops of the synthetic yarns have legs extending beyond the foundation layer by a predetermined length and the synthetic yarns show rigidity strength, whereby a flexible, resilient, light-weighted, and low-cost touch-fastening anti-skidding material is formed.
