Transparent textile with self-adhesive properties for damp environments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing textiles that can be stuck to transparent surfaces to control light intensity are not suitable for damp environments, as they tend to loosen over time due to moisture exposure, and lack the aesthetic appeal of traditional textiles.
Innovation Solution
A textile with threads that have a fibrous character and are impregnated with a moisture-blocking material, such as cross-linked acrylate, to prevent loosening from the adhesive in damp conditions, while maintaining the textile aspect and allowing one-way visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive is applied directly to threads to attach textile to transparent surface, then textile can be stuck to surface, but textile loosens in damp environments
Solution Approach 1:
A moisture blocking material is introduced as an intermediary layer between the adhesive and the threads. This intermediate layer prevents moisture from reaching the adhesive, thereby maintaining the attachment stability in damp environments while allowing the textile to be properly attached to the transparent surface.
Solution Approach 2:
The textile structure is transformed into a composite material system consisting of threads, adhesive, and moisture blocking material. This composite structure combines the attachment function of the adhesive with the moisture protection function of the blocking material, resolving the contradiction between adhesion and moisture resistance.
2Reliability
If moisture blocking material is applied between thread and adhesive, then textile remains attached in damp environments, but application complexity increases
Solution Approach 1:
The moisture blocking material is applied selectively at specific locations where moisture contact is most critical, rather than uniformly across the entire textile surface. This localized application maintains attachment stability in damp environments while minimizing the increase in application complexity.
3Shape
If adhesive is applied to preserve fibrous character, then textile aspect is retained, but adhesive coverage is reduced
Solution Approach 1:
The moisture blocking material serves as an intermediary that allows adhesive to be applied in a way that preserves the fibrous character. By placing the blocking material between the adhesive and threads, it enables selective adhesive placement that maintains textile appearance while providing sufficient coverage for attachment.
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 textile remains securely attached to transparent surfaces in damp environments, preserving its appearance and functionality for extended periods, allowing visibility from a lower light intensity to a higher light intensity while preventing the reverse view, even in bathrooms and kitchens.
Implementation Method 1
a moisture blocking material is applied at least between the thread material and an adhesive on one side of the threads in order to apply the textile to a transparent surface, wherein the moisture blocking material is such that it prevents the threads from loosening from the adhesive in damp environments

AI summary
Transparent textile with self-adhesive properties for damp environments The present invention relates to a textile (10) which is capable of being stuck to a transparent surface and which makes it possible to look out of a room with a lower light intensity into a room with a higher light intensity but which prevents looking out of a room with a higher light intensity inside into a room with a lower light intensity. The textile (10) comprises threads (11, 12) from thread material, wherein a moisture blocking material (30) is applied between the thread material and an adhesive (14) on one side of the threads (11, 12) for preventing the threads (11, 12) from loosening from the adhesive (14) in damp environments.
