Textile Product with Integrated Laundry Bag for Microfiber Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Textile products containing synthetic fibers release plastic fibers during washing, which are not effectively retained by conventional wastewater filters, leading to environmental pollution, and existing solutions like laundry bags are not universally adopted or focused on environmental protection.
Innovation Solution
Integration of a closable laundry bag made of heat-set plastic screen fabric with a mesh size between 5 μm and 200 μm into textile products, ensuring nearly 100% retention of plastic fibers during washing, with the bag being adaptable to the type and thickness of fibers and capable of accommodating additional items.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional wastewater filters are used, then the washing process is simple, but plastic fibers are not retained and environmental pollution occurs
Solution Approach 1:
The patent combines the laundry bag with the garment by integrating it into the garment's pocket or attaching it to the garment, creating a unified system. This merging approach eliminates the need for separate filtration devices while effectively capturing plastic fibers during washing.
Solution Approach 2:
The laundry bag acts as an intermediary between the garment and the washing machine environment. It captures plastic fibers released during washing and prevents them from entering the wastewater stream, thereby reducing environmental pollution without requiring complex wastewater treatment systems.
2Object-affected harmful factors
If a separate laundry bag is purchased and used, then plastic fiber retention is achieved, but user adoption is limited and convenience is reduced
Solution Approach 1:
The laundry bag is integrated directly into the garment structure, either as part of a pocket or attached to the garment. This integration ensures that every time the garment is washed, the laundry bag is automatically used, eliminating the need for users to separately purchase and remember to use a laundry bag.
Solution Approach 2:
The garment itself provides the filtration function through the integrated laundry bag. The system serves itself by automatically capturing plastic fibers during washing without requiring additional user action or separate devices.
3Object-affected harmful factors
If a laundry bag with small mesh size is used, then plastic fiber retention is improved, but washing performance may be compromised
Solution Approach 1:
The patent specifies an optimal mesh size range of 10-50 micrometers, which balances filtration effectiveness with washing performance. This parameter optimization ensures that the laundry bag retains plastic fibers while still allowing water and detergent to penetrate effectively for good washing results.
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 integrated laundry bag achieves a high retention rate of plastic fibers, reducing wastewater pollution effectively and maintaining good washing results, with the option to use it for multiple wash cycles and other clothing items.
Implementation Method 1
made of a thermofixed plastic mesh fabric with a mean mesh size in the range between 5 μm and 200 μm, which serves as a retention means for any plastic fibers washed out
