Pet Hair Removal from Textiles via Chemical Dissolution
Solution Overview
Problem
Pet hair accumulation on textiles and in washing machines is difficult to remove completely, leading to energy consumption, cost, and environmental concerns, with existing methods being inefficient and harmful to fabrics and machines.
Innovation Solution
A composition comprising a non-chlorine-based bleaching agent, a bleach activator, and an alkali is introduced into a washing machine to create a solution with a pH greater than 8.0, effectively dissolving pet hair from textiles without damaging the machine or fabric, using a concentration ratio of 40:1 to 3.3:1 for the bleaching agent to bleach activator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional washing methods are used to remove pet hair, then hair removal is partial and incomplete, but excessive washing and drying consumes significant energy and is time consuming
Solution Approach 1:
The patent changes the chemical parameters of the washing solution by introducing a composition with specific pH level (greater than 8.0) and controlled concentration ratio of bleaching agent to bleach activator (40:1 to 3.3:1). This chemical parameter modification enables effective hair dissolution with a single wash cycle, eliminating the need for multiple washing and drying cycles, thus reducing energy consumption while improving hair removal efficiency.
2Ease of operation
If lint rollers and vacuum cleaners are used to remove pet hair, then hair removal is partial, but the problem of pet hair remains resulting in excessive washing and drying
Solution Approach 1:
The patent replaces mechanical hair removal systems (lint rollers, vacuum cleaners) with a chemical dissolution system. The composition chemically dissolves pet hair through controlled oxidation and hydrolysis reactions, transforming the mechanical removal process into a chemical process that achieves complete hair removal in one treatment, improving both convenience and effectiveness.
3Reliability
If pet hair is not fully removed by laundering, then hair remains in the washing machine and tumble dryer to contaminate the same, but conventional washing methods are used
Solution Approach 1:
The patent modifies the chemical parameters of the washing solution to achieve complete hair dissolution. By controlling the pH level (greater than 8.0) and the concentration ratio of bleaching agent to bleach activator (40:1 to 3.3:1), the composition ensures complete hair removal and prevents hair contamination of the washing machine and tumble dryer, improving both machine cleanliness and hair removal completeness.
4Productivity
If chlorine-based bleaching agents are used to remove hair, then hair removal is effective, but harmful effects on fabrics and machines occur
Solution Approach 1:
The patent uses a non-chlorine-based bleaching agent that is safer for fabrics and machines compared to chlorine-based agents. This alternative bleaching system achieves effective hair removal without the harmful effects associated with chlorine, such as fabric deterioration and machine damage, while maintaining cost-effectiveness and environmental friendliness.
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 solution achieves at least 60% hair removal from textiles and the washing machine, reducing energy usage and environmental impact while maintaining fabric integrity and machine safety, providing a cost-effective and hygienically clean result.
Implementation Method 1
introducing a predetermined amount of a composition to the water to dissolve the hair, the composition comprising a non-chlorine-based bleaching agent, a bleach activator
Implementation Method 2
an alkali to provide a solution having a pH of greater than 8.0
