Pile-Knitted Cut-Resistant Glove for Insulation and Soft Touch
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 featuring a pile knitted fabric with ground yarns providing cut resistance and pile yarns forming loops, knitted at a gauge of less than 10, creating a heat insulation layer that interposes loops between the wearer's hand and the ground yarn, enhancing both cut resistance and heat insulation while maintaining a soft touch.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the glove is made with thicker knitted fabric and thicker yarn to improve cut resistance, then cut resistance properties are enhanced, but the glove becomes harder and scratchier, reducing comfort and soft touch feel
Solution Approach 1:
The knitted fabric is segmented into ground yarns (for cut resistance) and pile yarns (for comfort), with the pile yarns forming loops that are pulled out longer than the ground yarns. This segmentation allows the ground yarns to provide cut resistance while the pile yarns provide soft touch feel, resolving the contradiction between strength and comfort.
Solution Approach 2:
The pile yarns act as an intermediary layer between the wearer's hand and the ground yarns. The loops formed by pile yarns interpose between the hand and the potentially hard ground yarns, providing a soft touch feel while maintaining the cut resistance function of the ground yarns.
2Ease of operation
If the gauge is increased to 10 or more to improve workability and mobility, then ease of operation is enhanced, but heat insulation properties and cut resistance are reduced
Solution Approach 1:
The invention applies local quality by creating loops only in specific areas (where pile yarns are pulled out longer than ground yarns). These localized loops provide heat insulation and soft touch feel without requiring the entire fabric to be thick, thus maintaining workability and mobility while improving heat insulation.
3Strength
If the fabric weight is increased to improve cut resistance and heat insulation, then protection properties are enhanced, but workability and mobility deteriorate
Solution Approach 1:
The fabric structure is segmented into ground yarns and pile yarns with different functions. The ground yarns provide cut resistance while the pile yarns form loops for heat insulation. This segmentation allows achieving protection properties without uniformly increasing fabric weight, thus maintaining workability and mobility.
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 provides enhanced cut resistance, heat insulation, and a soft touch feel, with the loops retaining air for insulation and minimizing contact with the ground yarn, ensuring both protection and comfort.
Implementation Method 1
the plurality of loops tend to retain air in a surface part of the wearer's hand, providing heat insulation properties
