Solution Overview
Problem
Existing light-shielding textiles face challenges in achieving both transparent light and heat-insulating functions simultaneously, with issues in yarn flatness, weaving difficulties, high costs, and inadequate control over light permeability and heat insulation, as well as limitations in multi-layer structures and anisotropic effects.
Innovation Solution
A textile with a surface layer and underlying layer using high shrinkage-rate yarns and a combination of transparent and non-transparent weft yarns, where the arrangement and ratio of yarns control transmittancy and air layer thickness to achieve heat-insulating and transparent light effects, eliminating the need for special flat yarns or post-finishing processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If textile density is increased to block sunlight penetration, then light shielding function is improved, but transparent light function deteriorates
Solution Approach 1:
The textile is divided into multiple layers (surface layer, intermediate layer, underlying layer) with different functions. The surface and underlying layers use transparent yarns for light transmission, while the intermediate layer uses light-shielding yarns for blocking direct sunlight. This segmentation allows simultaneous achievement of both light shielding and transparent light functions.
Solution Approach 2:
Different regions of the textile have different optical properties. The surface and underlying layers are designed with transparent characteristics to allow scattered light penetration, while the intermediate layer has light-shielding properties to block direct sunlight. This local differentiation resolves the contradiction between blocking harmful light and maintaining transparent light transmission.
2Adaptability or versatility
If multiple layers are added to achieve both light shielding and transparent light functions, then functionality is improved, but device complexity increases
Solution Approach 1:
The patent combines light-shielding yarns and transparent yarns within a single textile structure, merging multiple functions into one integrated product. The surface layer and underlying layer are woven with specific patterns that simultaneously provide structural integrity, light transmission, and heat insulation functions, reducing the need for separate components.
Solution Approach 2:
The textile structure is designed to perform multiple functions simultaneously: light shielding, transparent light transmission, heat insulation, and UV protection. The combination of different yarn types and layer configurations enables the single textile product to serve as a multi-functional solution, avoiding the need for multiple separate layers or components.
3Object-affected harmful factors
If special flat yarns and post-finishing processes are used to achieve light shielding, then light shielding function is improved, but ease of manufacture deteriorates
Solution Approach 1:
The light-shielding yarns are pre-treated during the yarn manufacturing stage to achieve the desired optical properties, eliminating the need for post-finishing processes. The yarns are designed with specific cross-sectional shapes and material compositions that provide light shielding functionality directly upon weaving, simplifying the manufacturing process.
Solution Approach 2:
The textile structure itself provides the light shielding function through its inherent construction rather than requiring external treatments or post-processing. The combination of yarn arrangements, layer configurations, and material properties enables the textile to achieve light shielding automatically during the weaving process, without needing additional flatness treatments or coating processes.
4Temperature
If air layer thickness is increased to improve heat insulation, then heat insulating effect is improved, but textile thickness increases
Solution Approach 1:
The patent utilizes the three-dimensional spatial arrangement of multiple layers to create air gaps for heat insulation without significantly increasing overall thickness. By optimizing the vertical arrangement and spacing of the surface layer, intermediate layer, and underlying layer, the design maximizes heat insulation effectiveness within a compact thickness profile.
Solution Approach 2:
The patent optimizes parameters such as air layer thickness, layer spacing, and yarn density to achieve the desired heat insulation performance within acceptable thickness limits. By adjusting these parameters, the design balances heat insulation effectiveness with dimensional constraints, ensuring the textile remains practical for various applications.

Function Achieved in This Case
The textile effectively balances heat insulation and transparent light transmission, allowing adjustable light permeability and high shielding rates, while simplifying the weaving process and reducing costs, with improved aesthetic and functional properties.
Implementation Method 1
Through the multiple high shrinkage-rate yarns, an air layer is formed between the surface layer and the underlying layer, thus having the heat insulating effect
Implementation Method 2

AI summary
A textile with transparent light structure and heat-insulating construction and the method of manufacturing the same comprise a surface layer and an underlying layers the underlying layer and the surface layer have air layers and high shrinkage-rate yarns therein, and include non-transparent weft yarns and transparent yarns. By controlling the non-transparent yarn and the transparent yarn, the transparent light property can be obtained. Further, through the heat treatment, the multiple high shrinkage-percentage yarns thereto contract to make the surface layer and the underlying layer individually protruded. The air layers are just the heat insulating factor of the textile.
