Fabric Spray Composition for Heat-Free Crease Setting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Consumers face challenges in re-wearing garments that are not dirty, as existing fabric refresh sprays do not adequately restore the 'just washed' state, which is crucial for confidence in re-wearing clothes, and often require ironing, which can damage volatile perfumes.
Innovation Solution
An aqueous fabric spray composition containing 1-10 wt% silicone in emulsion form and 0.1-1.5 wt% setting polymer, allowing for rejuvenation of garments to a 'just washed' state without heat, enabling the removal of unwanted creases and insertion of new creases without ironing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing fabric refresh sprays are used, then some refresh aspects are provided, but the garments do not return to a 'just washed state' and consumers lack confidence to re-wear
Solution Approach 1:
The composition combines multiple functional components (silicone emulsion, setting polymer, fragrance, water) to create a composite spray formulation that simultaneously provides fabric softening, crease removal, and fragrance deposition, enabling comprehensive garment rejuvenation that restores the 'just washed state' and builds consumer confidence for re-wearing
2Shape
If ironing is used to remove creases, then creases are removed, but volatile perfume ingredients evaporate due to high temperature
Solution Approach 1:
The invention replaces the thermal-mechanical ironing process with a chemical-aerosol-based spray composition that removes creases through silicone emulsion and setting polymer action at ambient temperature, thereby eliminating the heat-induced evaporation of volatile perfume ingredients while still achieving effective crease removal
Solution Approach 2:
The invention changes the operating temperature parameter from high temperature (ironing at 230°C) to ambient temperature (spray application), which prevents the evaporation of volatile perfume ingredients while maintaining effective crease removal capability through the chemical action of the spray composition
3Shape
If ironing is used to set new creases, then creases are inserted, but the process is time-consuming and requires access to ironing equipment
Solution Approach 1:
The spray composition enables consumers to perform crease insertion themselves without needing to access ironing equipment or facilities, allowing busy consumers to quickly set new creases on garments wherever they are, saving time and providing convenience
4Reliability
If fabric refresh sprays are used to restore look and feel, then some aspects are improved, but comprehensive restoration to 'just washed state' is not achieved
Solution Approach 1:
The invention employs a carefully formulated composite composition containing silicone emulsion (1-10 wt%), setting polymer (0.1-1.5 wt%), fragrance (0.01-5 wt%), and water (balance), where each component contributes specific functions that work synergistically to comprehensively restore fabric look, feel, and fragrance, achieving the 'just washed state' despite the complexity of the multi-component formulation
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 composition effectively restores the look, feel, and fragrance of garments to a 'just washed' state, providing a thicker, newer feel, fibre protection, and enhanced fragrance while eliminating the need for ironing, particularly beneficial for busy consumers and those with volatile perfume ingredients.
