Method for spraying laundry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The laundry process often causes color fading in dyed fabrics, leading to premature wear and disposal, which can be financially and environmentally detrimental. Existing methods for color restoration are not universally effective.
Innovation Solution
An aqueous fabric spray composition comprising ester oil with at least two ester linkages and free perfume is applied to fabrics to prevent color fade, with the ester oil being a polyol ester like pentaerythritol tetraisostearate and the perfume being a mixture of blooming and substantive components, enhancing color longevity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional laundry processes are used, then fabrics are cleaned and maintained, but color fading occurs leading to premature wear
Solution Approach 1:
The fabric spray composition is applied to fabrics before washing to prevent color fading during the laundry process. The ester oil and free perfume formulation creates a protective layer that maintains color integrity through subsequent washing cycles, addressing color maintenance proactively rather than reactively
Solution Approach 2:
The invention uses specific chemical parameters - ester oil with at least two ester linkages and free perfume components - to achieve color protection. The molecular structure of the ester oil (multiple ester linkages) provides enhanced adhesion and protection compared to single-ester formulations, extending fabric life through improved chemical properties
2Reliability
If existing color restoration methods are applied, then some color fade is addressed, but they are not universally effective across different fabrics
Solution Approach 1:
The fabric spray composition is designed to be universally applicable across different fabric types and color dyes. The ester oil formulation with multiple ester linkages provides a versatile base that adheres to various fabric compositions, while the free perfume components offer broad-spectrum color protection regardless of the specific dye type or fabric material
