Recycled Textile Vacuum Cleaner Filter Bag Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vacuum cleaner filter bags made from non-woven materials have high costs and ecological concerns due to the use of virgin plastics, and existing biodegradable options are not effectively disposed of, necessitating a solution that balances performance with ecological and economic advantages.
Innovation Solution
A vacuum cleaner filter bag composed primarily of recycled materials, with a nonwoven fabric layer containing up to 95% dusty and/or fibrous recycled material from textile production, such as cotton linters, and 5% binding fibers, preferably bicomponent fibers made from recycled plastics, which are thermally activated for binding, and additional layers formed from recycled plastics to enhance mechanical strength and filtration performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If nonwoven materials made from virgin plastics are used for filter bags, then mechanical strength and filtration performance are improved, but material costs and ecological impact increase
Solution Approach 1:
The patent applies the principle of discarding and recovering by using recycled textile waste materials (cotton linters, textile dust) that would otherwise be discarded as waste products. These recovered materials are processed into nonwoven filter bags, replacing virgin plastics and reducing ecological impact while maintaining functional performance through controlled nonwoven fabrication processes.
Solution Approach 2:
The patent applies parameter changes by transforming the physical and chemical properties of recycled textile waste through controlled processing parameters. The waste materials undergo changes in fiber arrangement, bonding structure, porosity, and mechanical properties during nonwoven fabrication, converting low-value waste into high-performance filter materials with tailored filtration characteristics.
2Reliability
If high-quality nonwoven materials are used for disposable filter bags, then service life and filtration performance are improved, but cost increases
Solution Approach 1:
The patent recovers value from discarded textile waste materials (cotton linters, dust) that have minimal or negative economic value. By processing these waste streams into functional nonwoven filter bags, the manufacturing cost of raw materials is significantly reduced compared to using virgin plastics, while achieving adequate service life for disposable filter applications.
Solution Approach 2:
The patent embraces the disposable nature of vacuum cleaner filter bags by designing cost-effective nonwoven structures from recycled waste materials. The filter bags are engineered to provide adequate service life for their intended application while maintaining low manufacturing costs, aligning with the economic reality that these are replacement consumables rather than permanent components.
3Object-affected harmful factors
If biodegradable materials are used for filter bags to improve ecological properties, then biodegradability is improved, but disposal effectiveness deteriorates because incineration is required and composting is not possible
Solution Approach 1:
The patent applies discarding and recovering in reverse - instead of making materials biodegradable for easy disposal, it recovers value from discarded waste materials to create durable filter bags. The resulting product maintains structural integrity for its service life and can be disposed of through standard incineration or landfill processes, avoiding the disposal problems associated with biodegradable materials that require specific composting infrastructure.
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 filter bag achieves excellent dust separation performance and service life while significantly reducing material costs and ecological impact by utilizing a high proportion of recycled materials, meeting or exceeding market standards and adhering to ecological standards like the Textile Exchange Global Recycle Standard.
Implementation Method 1
the layer of the nonwoven fabric comprising at least one dust and/or fibrous recycled material and/or cotton linters contains up to 95% by weight of the dust and/or fibrous recycled material and/or cotton linters and at least 5% by weight of binding fibers, in particular bicomponent fibers, or consists of them
