Loop Yarn Glove Coating for Anti-Slip and Flexibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gloves with anti-slipping coating layers made of rubber or resin have inadequate followability and heat-retaining properties, and the anti-slipping effect deteriorates due to detachment of anti-slipping particles, with insufficient ten-point mean roughness and bending flexibility.
Innovation Solution
A glove with a fiber body using loop yarn as knitting yarn, providing irregularities on the coating layer surface, secured by a presser yarn to prevent particle detachment, and a coating layer on the palm region for enhanced anti-slipping and heat retention, with specific parameters for loop diameter, distance, and fineness for optimal performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a coating layer is made from rubber with anti-slipping particles incorporated through kneading, then the coating layer provides anti-slipping effect, but the surface has small irregularities (Rz 40-90 μm) and the coating layer is hard to deform, leading to inferior followability
Solution Approach 1:
The patent changes the surface morphology parameters of the coating layer by incorporating loop yarn with specific loop diameters (1-6mm) and densities (5-20 loops/cm), transforming the surface from smooth (Rz 40-90μm) to highly irregular (Rz 300-1200μm), thereby improving both anti-slipping effect and followability simultaneously
Solution Approach 2:
The patent creates a composite structure combining the coating layer material (resin or rubber) with loop yarn elements, forming a hybrid material system that integrates the adhesive properties of the coating with the mechanical irregularities of the loop yarn, achieving superior anti-slipping performance and deformability
2Reliability
If pile fabric is used on the outer surface to increase surface roughness, then the glove exhibits inferior bending flexibility and is rigid due to short average distance between loops
Solution Approach 1:
The patent optimizes the loop yarn parameters including loop diameter (1-6mm, larger than conventional pile), loop density (5-20 loops/cm, lower than conventional pile), and stitch type, creating a knitted fabric structure that provides sufficient surface irregularities while maintaining large inter-loop spaces that enable excellent bending flexibility
Solution Approach 2:
The patent uses loop yarn where each loop acts as an independent irregularity element on the surface, while the spaces between loops provide flexibility zones, segmenting the fabric structure to simultaneously achieve roughness and flexibility that cannot be obtained with continuous pile fabric
3Reliability
If pile fabric faces outside to provide surface irregularities, then heat-retaining property is inferior due to absence of loop on the inner surface that contacts hand skin
Solution Approach 1:
The patent makes the loop yarn structure serve dual functions: the loops projecting outward provide surface irregularities for anti-slipping, while the corresponding loops on the inner surface provide heat retention by contacting the hand skin, eliminating the need to choose between one function or the other
4Reliability
If conventional coating layers are used, then anti-slipping particles are incorporated but a part of the coating layer is likely to be detached together with anti-slipping particles, leading to deterioration of anti-slipping effect
Solution Approach 1:
The patent creates a composite where loop yarn elements are integrated into the coating layer matrix, forming a unified structure where the coating and irregularity-providing elements cannot separate, eliminating the detachment problem of conventional particle-based anti-slipping coatings
Solution Approach 2:
The patent merges the anti-slipping function and the surface irregularity function into a single integrated loop yarn structure, where the loops themselves provide the irregularities rather than separate particles, ensuring permanent attachment and long-lasting anti-slipping effect

AI summary
A glove includes: a glove body made of fibers, the glove body being for covering a hand of a wearer; and a coating layer made of a resin or rubber, the coating layer being overlaid at least on a palm region of the outer surface of the glove body, in which a loop yarn is used as a knitting yarn of the glove body, and irregularities arising from the loop yarn are provided on the surface of the coating layer. The ten-point mean roughness (Rz) of the surface of the coating layer is preferably no less than 300 μm and no greater than 1,200 μm. The average outer diameter of loops of the loop yarn is preferably no less than 1 mm and no greater than 6 mm. The average distance between loops of the loop yarn is preferably no less than 1 mm and no greater than 10 mm.
