Woven Shielding Textile Double Beam Weaving Light Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing woven textiles fail to effectively block visible and ultraviolet electromagnetic radiation without compromising mechanical properties, breathability, or aesthetic appeal, as they often require synthetic polymer coatings that decrease flexibility and increase heat retention.
Innovation Solution
A woven shielding textile is created using a double beam weaving system with primary and secondary warp yarns interlaced with weft yarns, forming a warp-faced fabric that blocks 90-100% of light without a light-blocking coating, maintaining breathability and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a synthetic polymer coating is applied to block visible and UV light, then electromagnetic radiation shielding is improved, but mechanical properties and breathability deteriorate
Solution Approach 1:
The patent removes the synthetic polymer coating from the textile structure entirely. Instead, it uses a specific weaving pattern with tightly packed yarns to achieve light blocking. This extraction eliminates the harmful effects of the coating while maintaining the primary function of electromagnetic radiation shielding through structural design alone.
Solution Approach 2:
The textile is designed with multiple layers of interlaced yarns creating a segmented structure with numerous small pores. This segmentation approach blocks electromagnetic radiation through multiple interfaces and reflections, achieving shielding without requiring a continuous polymer coating that would compromise mechanical properties.
2Object-affected harmful factors
If a synthetic polymer coating is applied to block visible and UV light, then electromagnetic radiation shielding is improved, but breathability deteriorates
Solution Approach 1:
The patent eliminates the synthetic polymer coating that would trap moisture and heat. The breathable textile achieves UV and visible light blocking through its woven structure alone, allowing moisture vapor to pass through the pores while maintaining electromagnetic radiation shielding.
Solution Approach 2:
The textile employs different yarn orientations and densities in different regions of the fabric structure. The warp and weft yarns are arranged to create optimal pore sizes that selectively block electromagnetic radiation while permitting moisture vapor transmission, achieving local optimization of both shielding and breathability.
3Object-affected harmful factors
If a synthetic polymer coating is applied to block visible and UV light, then electromagnetic radiation shielding is improved, but aesthetic appeal deteriorates
Solution Approach 1:
The patent removes the unsightly synthetic polymer coating from the textile surface. The aesthetic appeal is maintained by using the natural appearance of the woven yarns themselves, which can be dyed and textured to provide visual appeal while the weaving pattern provides the electromagnetic radiation shielding function.
4Object-affected harmful factors
If a synthetic polymer coating is applied to block visible and UV light, then electromagnetic radiation shielding is improved, but flexibility deteriorates
Solution Approach 1:
The patent eliminates the rigid synthetic polymer coating that would restrict bending and movement. The flexible textile achieves electromagnetic radiation shielding through its woven structure, allowing the fabric to bend and conform to different shapes while maintaining its shielding capability.
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 solution provides a lightweight, breathable, and aesthetically pleasing fabric that effectively blocks visible and ultraviolet radiation, suitable for various applications including military tents and personal use, while maintaining mechanical properties and flexibility.
Implementation Method 1
Visible light and ultraviolet radiation may primarily penetrate woven textiles by penetrating through a set of pores that exist between an interlacing of a set of weft yarns and a set of warp yarns
Implementation Method 2
Some visible and ultraviolet radiation may also pass directly through the yarns of the woven textile or pass by indirect diffraction through the textile

AI summary
A woven shielding textile includes a set of weft yarns and a plurality of warp yarns, including a set of primary warp yarns and a set of secondary warp yarns. The set of primary warp yarns and the set of secondary warp yarns are selectively interlaced with the set of weft yarns using a double beam weaving system such that the woven shielding textile is warp-faced. A face surface is predominantly composed of the set of primary warp yarns and a back surface is predominantly composed of the set of secondary warp yarns, while the plurality of warp yarns alternates between the set of primary warp yarns and the set of secondary warp yarns. A substantial percent of light incident to the woven shielding textile does not pass through.
