Multi-Stitch Single Knitted Fabric for Moisture and Warmth Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-layer knitted fabrics face inefficiencies in the performance of their functions, particularly in how the layer facing the skin interacts with moisture and warmth, due to the structure of the yarns used.
Innovation Solution
A single knitted fabric with three or more multiple stitches, incorporating at least one elastic yarn and two front yarns with varying knitting methods, where one front yarn is knitted with float knitting to expose loops on one surface and the other with flat knitting on the opposite surface, enhancing the interaction with the skin and optimizing moisture and warmth management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If both surfaces are knitted with flat knitting, then the fabric structure is dense, but the functional yarn cannot come into contact with the skin efficiently
Solution Approach 1:
The fabric is divided into two distinct surfaces with different knitting methods: the first surface uses flat knitting for density, while the second surface uses float knitting to expose loops that contact the skin. This segmentation allows each surface to perform its specific function optimally without compromising the other.
Solution Approach 2:
Different regions of the fabric have different knitting structures tailored to their specific functions. The first surface has a dense flat-knitted structure for external protection, while the second surface has a loose float-knitted structure with exposed loops for skin contact and moisture management, creating local quality variations that optimize overall performance.
2Reliability
If float knitting is used to expose loops on the skin-facing surface, then moisture management efficiency is improved, but the fabric structure becomes less dense
Solution Approach 1:
The fabric structure is segmented into two surfaces with different densities. The float-knitted second surface has lower density to allow loop exposure and moisture management, while the flat-knitted first surface maintains higher density for structural stability, resolving the contradiction between moisture management efficiency and fabric density.
Solution Approach 2:
The fabric exhibits local quality variations where the skin-facing second surface has a loose, open structure optimized for moisture wicking and skin contact, while the opposite first surface has a dense structure for protection and stability. This local differentiation allows the fabric to achieve both moisture management efficiency and overall structural integrity.
3Reliability
If multiple yarns with different properties are combined, then functional performance is enhanced, but the manufacturing complexity increases
Solution Approach 1:
Multiple yarns with different functional properties (elastic yarn and front yarns with varying elasticity and hydrophobicity) are merged into a single knitted fabric structure. This combining allows the fabric to achieve enhanced functional performance through the synergistic interaction of different yarn properties while maintaining a unified manufacturing process.
Solution Approach 2:
The knitted fabric structure serves multiple functions simultaneously: the elastic yarn provides stretch and recovery, the front yarns with different hydrophobicity levels manage moisture transport, and the differential knitting methods create both dense and loose regions. This multi-functionality is achieved within a single fabric structure rather than requiring separate components.
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 fabric efficiently manages moisture and warmth by minimizing moisture return to the skin and maximizing warmth retention, while maintaining a dense surface structure to reduce external air entry.
Implementation Method 1
the sinker-side loops of the front yarn knitted with float knitting are exposed in a floating state on a side of a second surface... allows the front yarn to come into contact with the skin more easily
Implementation Method 2
the front yarns knitted with float knitting are more hydrophobic than the front yarns knitted with flat knitting... minimizing the return of moisture from the skin
Implementation Method 3
the side of the first surface is knitted with flat knitting... allows the side of the first surface of the single knitted fabric to remain dense... minimizing the contact of moisture from the outside

AI summary
An objective of the present invention is to allow a layer facing the skin in multi-layer knitted fabric described above to perform its functions more efficiently. Single knitted fabric of the present invention is single knitted fabric having three or more multiple stitches, and is knitted with at least one elastic yarn and at least two front yarns. Note that the at least two front yarns have lower elasticity than the elastic yarn. Further, at least one of the at least two front yarns is knitted with flat knitting. The needle-side loops of the front yarn knitted with flat knitting are exposed on a side of a first surface. Additionally, at least one of the at least two front yarns is knitted in float knitting. The sinker-side loops of the front yarn knitted with float knitting are exposed on a side of a second surface, which is a surface of the opposite side of the first surface, in a floating state.
