Silicone Textile Coating for Anti-Slip Grip Without Staining
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing silicone coatings for textiles struggle to achieve a balance between anti-slip properties and user comfort, often requiring excessive compression due to insufficient tack, and can cause aesthetic and staining issues due to deep penetration into the textile.
Innovation Solution
A silicone elastomeric composition crosslinkable by polyaddition, comprising specific polyorganosiloxanes and hydrogenopolysiloxanes, is applied to textiles, optimizing adhesion without excessive compression and preventing oily substance release, using a process that includes precise molar ratios and deposition methods to ensure non-toxicity and odorlessness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If silicone composition is strongly impregnated into textile material to improve adhesion, then adhesion effect is enhanced, but aesthetic appearance deteriorates and transfer to other side occurs
Solution Approach 1:
The patent modifies the rheological parameters of the silicone composition by adding thixotropic agents, which changes the viscosity behavior from Newtonian to thixotropic. This allows the composition to remain stable during coating and prevent deep penetration, while still providing adequate adhesion to the textile surface.
2Reliability
If compression of textile material is increased to ensure anti-slip effect, then anti-slip function is improved, but user comfort deteriorates
Solution Approach 1:
The patent changes the tack parameters of the silicone composition by optimizing the crosslinking density and composition formulation. This increases the adhesive strength at the textile-skin interface, allowing the anti-slip function to be achieved with reduced compression force, thereby improving user comfort.
3Ease of operation
If silicone composition is made more adhesive to reduce compression, then user comfort is improved, but oily substance release increases causing staining
Solution Approach 1:
The patent creates a composite silicone formulation combining multiple polysiloxane components with different functions: one component provides adhesion and tack, while another component provides crosslinking and structural stability. This composite approach allows high adhesion without excessive oil release, as the crosslinked network prevents migration of oily substances.
4Object-generated harmful factors
If crosslinking density is increased to prevent oily substance release, then staining is prevented, but adhesion effect may be reduced
Solution Approach 1:
The patent uses a multi-component silicone system where different polysiloxanes perform complementary functions. The formulation balances crosslinking density to prevent oil migration while maintaining sufficient adhesive properties through the specific combination of components and their ratios.
