Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing double-knitted fabrics do not effectively address air conditioning and climate compensation, particularly in terms of moisture absorption and air permeability, which is crucial for direct or indirect body contact applications such as upholstery or bedding.
Innovation Solution
A double-knitted fabric design featuring alternating sections with a filling thread for moisture absorption and spacer threads for ventilation, produced using a knitting machine, where the filling thread extends beyond the height of the spacer thread, ensuring efficient moisture absorption and ventilation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If filling threads are inserted into the intermediate space to improve moisture absorption, then moisture absorption capability is improved, but air permeability deteriorates
Solution Approach 1:
The fabric is divided into first sections containing filling threads for moisture absorption and second sections containing spacer threads for ventilation, allowing both functions to coexist without interfering with each other
Solution Approach 2:
Different sections of the fabric have different local properties: first sections are optimized for moisture absorption with filling threads, while second sections are optimized for air permeability with spacer threads
2Object-generated harmful factors
If spacer threads are used to improve air permeability, then air permeability is improved, but moisture absorption capability deteriorates
Solution Approach 1:
The fabric structure is segmented into alternating first and second sections, where spacer threads are confined to second sections to preserve air permeability while filling threads in first sections provide moisture absorption
Solution Approach 2:
Spacer threads are locally placed in second sections to create ventilation channels without occupying the entire fabric structure, allowing moisture absorption functionality to be maintained in first sections
3Quantity of substance
If filling threads extend beyond spacer thread height to improve moisture absorption, then moisture absorption is improved, but fabric complexity increases
Solution Approach 1:
The fabric is organized into repeating first and second sections with distinct functions, creating a manageable modular structure that reduces overall complexity despite the varied thread arrangements
Solution Approach 2:
The first and second sections are merged into a single integrated fabric structure produced by knitting machines, combining moisture absorption and ventilation functions in one homogeneous material

AI summary
The present invention relates to a knitted or woven fabric in the form of a double-layered knitted fabric. The object of the present invention is to further develop such a fabric in such a way that its climate control or climate regulation is improved, in particular by providing high moisture absorption and release through the fabric and simultaneously high air permeability through the fabric.The problem is solved by a knitted or woven fabric in the form of a double-layered knitted, woven or crocheted fabric, with an upper (1) and lower (2) textile side, which are spaced apart from each other forming an interval (6), with first and second sections repeating in the longitudinal (5) or transverse (9) direction of the fabric, wherein at least one insert (3) is inserted in each of the first sections (7), and at least one spacer thread (4) spanning and stretching the interval (6) is provided in each of the second sections (8), characterized in that the extension of the insert in the direction of the height of the interval is greater than the height of the interval in the second section.
