Pile-Knitted Cut-Resistant Glove Balancing Warmth and Mobility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cut resistant gloves do not effectively combine cut resistance, heat insulation, and a soft touch feel, and often compromise on workability and mobility.
Innovation Solution
A cut resistant glove with a pile knitted fabric structure, where a ground yarn provides cut resistance and a pile yarn forms loops on the back stitch, creating a heat insulation layer that prevents direct contact with the ground yarn, enhancing both insulation and softness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a cut resistant glove uses a knitted fabric with gauge of 10 or more to maintain workability and mobility, then the workability and mobility are improved, but the cut resistance properties and heat insulation properties deteriorate
Solution Approach 1:
The patent changes the knitting gauge parameter from 10 or more to less than 10, which creates a thicker knitted fabric structure. This parameter change simultaneously improves cut resistance by providing more material layers to resist cutting forces and enhances heat insulation by creating thicker air pockets between yarns, while the flexible yarn composition maintains workability and mobility.
Solution Approach 2:
The patent uses composite yarns consisting of cut-resistant fibers (such as para-aramid or polyethylene) combined with heat-insulating fibers. This composite material approach allows the glove to achieve both cut resistance and heat insulation properties simultaneously, resolving the contradiction between protective performance and operational comfort.
2Reliability
If a cut resistant glove uses thick knitted fabric to improve cut resistance properties, then the cut resistance properties are improved, but the soft touch feel and comfort deteriorate
Solution Approach 1:
The patent applies local quality by using different yarn types in different regions of the fabric structure. The outer surface uses soft, flexible yarns to provide a comfortable touch feel against the skin, while the inner structural layers use high-strength cut-resistant fibers to provide protection. This spatial differentiation of material properties resolves the contradiction between thickness for protection and softness for comfort.
Solution Approach 2:
The patent employs flexible yarns with low stiffness in the outer layers that contact the wearer's hand. These flexible shells provide a soft touch feel while the overall fabric thickness is maintained through the knitting structure rather than individual yarn thickness, allowing comfort without sacrificing cut resistance.
3Temperature
If a cut resistant glove increases fabric weight to improve heat insulation properties, then the heat insulation properties are improved, but the workability and mobility deteriorate
Solution Approach 1:
The patent utilizes the porous structure created by the knitting process itself to provide heat insulation. The knitted fabric naturally forms air pockets between yarns that act as thermal insulation layers. By optimizing the knitting pattern and yarn arrangement rather than simply increasing fabric weight, the glove achieves heat insulation while maintaining flexibility and workability.
Solution Approach 2:
The patent ensures continuous flexibility and mobility through the use of elastic yarns and flexible fiber compositions throughout the entire fabric structure. This allows the glove to maintain workability and mobility even with increased thickness for heat insulation, as the material continuously adapts to hand movements without restricting motion.
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 glove achieves improved cut resistance, heat insulation, and a soft touch feel by interposing loops between the wearer's hand and the ground yarn, providing effective protection and comfort in low-temperature environments.
Implementation Method 1
the plurality of loops are easily interposed between the ground yarn of the pile knitted fabric and the wearer's hand when the cut resistant glove is worn. That is, the interposition of the plurality of loops makes it difficult for the wearer's hand of the cut resistant glove to come into contact with the ground yarn
Implementation Method 2
the plurality of loops tend to retain air in a surface part of the wearer's hand, providing heat insulation properties

AI summary
Provided is a cut resistant glove including a pile knitted fabric. The pile knitted fabric includes a plurality of yarns that contain a ground yarn having cut resistance properties and a pile yarn, and are pile-knitted at a gauge of 6 or more and less than 10. The pile yarn is pulled out longer than the ground yarn from a back stitch of the pile knitted fabric to form a plurality of loops.
