Low-Viscosity Fabric Spray Composition for Wrinkle Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fabric treatment methods require chemical bonding with the fabric for anti-wrinkle properties, which is not applicable to all fabric types and lacks a convenient, non-rinse cycle solution for wrinkle removal and softening.
Innovation Solution
A portable, spray-dispersible liquid chemical composition containing a combination of wrinkle remover, fabric softener, and viscosity reducer, formulated as an aqueous mixture with a viscosity of 1.0 to 2.0 centipoise, allowing for easy application without a washing machine, using a dispensing bottle with a spray nozzle and flow rate regulating mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If chemical bonding treatment is applied to fabric for anti-wrinkle properties, then wrinkle resistance is improved, but applicability to all fabric types deteriorates and fabric breathability is reduced
Solution Approach 1:
The treatment system is segmented into two independent components: a substrate-containing composition applied to the fabric, and a separate activating solution. This segmentation allows the substrate to remain on the fabric surface without chemical bonding, enabling universal applicability across different fabric types while maintaining wrinkle resistance through the activation process.
Solution Approach 2:
The patent introduces an intermediary activating solution that triggers the wrinkle-resistant effect without requiring permanent chemical bonding to the fabric. The substrate remains on the fabric surface and is activated by the solution, serving as a mediator that enables wrinkle resistance while preserving fabric breathability and universal compatibility.
2Ease of operation
If rinse-cycle fabric conditioning is used, then fabric softness and static control are improved, but convenience deteriorates due to requirement of washing machine rinse cycle
Solution Approach 1:
The substrate-containing composition is applied to the fabric in advance, before the actual softening action is needed. The substrate remains dormant until activated by the separate solution, allowing the fabric to be treated and softened without requiring a full rinse cycle in the washing machine, thus simplifying the process while maintaining effectiveness.
3Reliability
If permanent press finishes are applied to fabric, then wrinkle resistance is improved, but fabric breathability deteriorates due to coating or crosslinking filling interstices
Solution Approach 1:
By separating the substrate application from the activation step, the system avoids the need for coatings or crosslinking that would fill fabric interstices. The substrate remains on the surface and is activated in situ, providing wrinkle resistance while preserving the fabric's natural breathability.
Solution Approach 2:
The activating solution serves as an intermediary that enables wrinkle resistance without requiring permanent chemical bonding or coating formation. This mediator approach allows the substrate to function without filling fabric pores, thus maintaining breathability while achieving the desired wrinkle-resistant effect.

AI summary
An apparatus includes a dispensing bottle including a reservoir and a spray nozzle in fluid communication therewith, and a homogenous solution housed within the reservoir. Such a homogenous solution includes between 40% and 45%, by weight, of a wrinkle remover; between 40% and 45%, by weight, of a fabric softener; and between 10% and 20%, by weight, of a viscosity reducer. Advantageously, the solution is an aqueous mixture having a viscosity level between 1.0 and 2.0 centipoise at 25 degrees Celsius wherein, upon actuating the spray nozzle, the solution is caused to expel outwardly and away from the reservoir due to its low viscosity characteristics.
