Microfiber Glove Inner Surface Friction and Coating Adhesion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gloves with fibrous coatings suffer from insufficient slip resistance on both the inner and outer surfaces, leading to issues like fingers slipping inside the glove and the glove coming off during use, especially when applying force, and inadequate adhesion strength of the coating layer.
Innovation Solution
A glove design featuring a fibrous base with microfibers on the inner surface and non-microfibers on the outer surface, coated with a rubber or vinyl chloride-based resin, where the microfibers have a diameter of not more than 6 µm and the non-microfibers are larger, enhancing friction and adhesion respectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a coating layer of rubber or vinyl chloride-based resin is formed on the outer surface side of a fibrous glove made of microfibers, then the slip resistance of the inner surface side is improved, but the adhesion strength between the coating layer and microfibers is low causing the coating to peel off during use
Solution Approach 1:
The patent applies different fiber types to different surfaces: microfibers on the inner surface side for slip resistance and non-microfibers on the outer surface side for coating adhesion. This local differentiation resolves the contradiction by optimizing each surface for its specific function rather than using uniform microfibers throughout.
Solution Approach 2:
The glove uses a composite structure combining microfibers and non-microfibers in different regions. The outer surface layer comprises non-microfibers that provide excellent adhesion for the coating layer, while the inner surface layer comprises microfibers that provide high friction and slip resistance, creating a multi-functional composite material system.
2Object-affected harmful factors
If long fibers such as polyester and polyamide are used in fibrous gloves, then the gloves are suitable for dust-prone fields, but the slip resistance is insufficient due to smaller frictional resistance with hand skin
Solution Approach 1:
The patent differentiates fiber usage by location: long fibers are used in the bulk structure where dust control is needed, while microfibers are specifically placed on the inner surface where slip resistance is critical. This local quality differentiation allows each region to optimize for its primary function.
Solution Approach 2:
The patent changes the fiber diameter parameter from long fibers (conventional) to microfibers (≤6 μm) specifically for the inner surface contact area. This parameter change increases the frictional resistance with hand skin while maintaining the dust-prone field suitability through the overall fibrous structure.
3Ease of operation
If microfibers with diameter not more than 6 µm are used on the inner surface side, then the frictional resistance to fingers is high improving slip resistance, but the adhesion strength of the coating layer on the outer surface side becomes low
Solution Approach 1:
The patent segments the fibrous structure into distinct regions: an inner surface layer with microfibers for slip resistance and an outer surface layer with non-microfibers for coating adhesion. This segmentation allows each region to be optimized independently for its specific function without compromise.
Solution Approach 2:
Different fiber properties are assigned to different locations: microfibers are concentrated on the inner surface where high friction is needed, while non-microfibers are positioned on the outer surface where coating adhesion is critical. This local quality optimization resolves the contradiction between slip resistance and coating adhesion strength.

Function Achieved in This Case
The glove achieves superior slip resistance on both surfaces and prevents peeling of the coating layer, ensuring high performance and reliability during use.
Implementation Method 1
the inner surface side of the fibrous glove includes a yarn comprising 50% by weight or more of a microfiber having a diameter of a monofilament of not more than 6 µm... the microfiber which has high frictional resistance to fingers
Implementation Method 2
a coating layer of a rubber or a vinyl chloride-based resin has been formed on the outer surface side of the fibrous glove... the coating layer has excellent adhesion strength to the outer surface side of the glove
