Fabric-care composition comprising silicone materials
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fabric-care compositions face challenges in protecting fabrics from harsh laundry conditions, such as pilling, shrinkage, and loss of color intensity, while also failing to provide effective static reduction and color retention.
Innovation Solution
The use of uncured silicone-based polymers in fabric-care compositions, specifically with the formula (R1O)3-x—Si(R2)x—(Z)d—(O)q—(R32SiO)N—(SiR32—Z)d—Si(R2)y(OR1)3-y, combined with fabric-care ingredients in a medium, which can be in the form of liquid, paste, or granular formulations, to enhance fabric softening, color care, and prevent damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional fabric-care compositions are used, then basic cleaning function is provided, but fabric protection from harsh laundry conditions is insufficient
Solution Approach 1:
The patent employs uncured silicone-based polymers as a composite material that forms a protective coating on fabric surfaces. This silicone polymer composition creates a flexible protective layer that shields fabric from mechanical damage, chemical degradation, and color fading during laundry processes, thereby enhancing fabric protection while maintaining flexibility and softness.
Solution Approach 2:
The patent utilizes the uncured state of silicone-based polymers as a key parameter change, allowing the material to remain flexible and adaptable during application and washing. The uncured polymer can penetrate and bond with fabric fibers more effectively, providing superior protection compared to cured silicone materials, while still delivering the desired fabric care benefits.
2Ease of operation
If fabric-care compositions are used, then some fabric softening is achieved, but effective static reduction is not provided
Solution Approach 1:
The uncured silicone-based polymer composition performs multiple functions simultaneously: it softens fabric by coating fibers, reduces static cling through its conductive properties, and provides protection during washing. This multi-functional approach eliminates the need for separate treatments for softening and static reduction, addressing both issues with a single composition.
3Stability of the object's composition
If conventional fabric-care ingredients are used, then basic color care is provided, but effective color retention and fastness are not achieved
Solution Approach 1:
The silicone-based polymer acts as a composite protective layer that encapsulates and protects fabric colors from fading and loss during washing. This protective coating prevents direct exposure of colored fibers to harsh washing conditions, thereby improving color retention and fastness while maintaining the fabric's original color intensity and shade.
4Reliability
If fabric-care compositions are used, then some fabric protection is provided, but comprehensive protection against pilling, shrinkage, and color loss is insufficient
Solution Approach 1:
The uncured state of the silicone polymer provides enhanced flexibility and adaptability, allowing it to conform to fabric structures and provide comprehensive protection against various forms of degradation including pilling, shrinkage, and color loss. The uncured polymer can better penetrate fabric matrices and form stronger bonds, delivering superior multi-faceted protection compared to conventional cured silicone materials.
