Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mop fabrics fail to effectively adsorb dust and kill bacteria, leading to inadequate cleanliness in high-cleanliness environments such as aseptic rooms, as they do not efficiently remove killed bacteria.
Innovation Solution
A fabric production method involving an impermeable base layer, a polyester brocade microfiber surface layer, and an intermediate adsorbent layer, treated with alkali fiber-splitting and degreasing processes, followed by ultrasonic lamination to create a composite material with enhanced adsorption and bactericidal properties, and a buckle design for easy handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional mop fabric is used, then the fabric structure is simple and easy to manufacture, but the fabric cannot effectively adsorb dust and kill bacteria
Solution Approach 1:
The patent applies composite materials by combining three distinct fabric layers: a polyester brocade microfiber fabric surface layer for adsorption, an intermediate adsorbent layer for enhanced dust and bacteria capture, and an impermeable fabric base layer for structural support and fluid barrier. This multi-layer composite structure resolves the contradiction by integrating multiple functions (adsorption, bactericidal action, structural integrity) that a single conventional fabric cannot achieve, while maintaining manufacturability through layer-by-layer assembly.
Solution Approach 2:
The patent segments the fabric into three functional layers, each performing a specific task: the surface layer for initial contact and adsorption, the intermediate layer for enhanced filtration and bactericidal action, and the base layer for structural support. This segmentation allows each layer to be optimized for its specific function, achieving superior overall performance without excessive complexity, as the layers can be manufactured separately and assembled systematically.
2Reliability
If conventional mop fabric is used, then the manufacturing process is simple, but the fabric cannot adsorb moisture and dust effectively
Solution Approach 1:
The patent uses composite materials with three specialized layers: polyester brocade microfiber fabric for moisture and dust adsorption, an intermediate adsorbent layer for enhanced capture capability, and an impermeable base layer for structural support. This composite structure achieves superior adsorption performance by combining materials with complementary properties, while the standardized layer-by-layer manufacturing process maintains production efficiency.
Solution Approach 2:
The patent applies local quality by giving each layer specific properties tailored to its function: the surface layer uses polyester brocade microfiber for high surface area and adsorption capacity, the intermediate layer uses adsorbent materials for enhanced dust and bacteria capture, and the base layer uses impermeable fabric for fluid barrier properties. This localized optimization of material properties throughout the fabric structure achieves superior overall adsorption performance.
3Reliability
If bacteria are killed by bactericide, then bactericidal effect is achieved, but the killed bacteria cannot be removed by the mop
Solution Approach 1:
The patent combines bactericidal treatment with enhanced adsorbent layers in a composite structure. The bactericide is applied to kill bacteria, while the intermediate adsorbent layer with high surface area and porous structure captures and removes the killed bacteria along with dust and moisture. This composite approach ensures both bactericidal effect and effective removal of contaminants, resolving the contradiction between killing bacteria and removing them.
Solution Approach 2:
The intermediate adsorbent layer acts as an intermediary between the bactericidal surface layer and the base layer. It receives the killed bacteria and dust particles from the surface layer and transports them to the base layer for removal. This intermediary layer ensures that the bactericidal effect is maintained while simultaneously enabling effective removal of the killed bacteria and contaminants.

Function Achieved in This Case
The resulting fabric demonstrates strong cleaning capacity and adsorption ability, capable of killing bacteria, adsorbing dust and moisture, and preventing cross-contamination, effectively cleaning areas up to 8-10 square meters.
Implementation Method 1
Before fiber opening, the fineness of ultra-fine fiber in the polyester brocade microfiber fabric is not much different from that of ordinary fiber. When the fiber is opened by alkali fiber-splitting treatment, some polyester fiber is dissolved in strong alkali and high temperature condition, the polyester and the nylon fiber are cracked and peeled off
Implementation Method 2
When the fiber is opened by alkali fiber-splitting treatment, some polyester fiber is dissolved in strong alkali and high temperature condition
Implementation Method 3
employing an ultrasonic laminating machine to laminate the three layers of materials into one, thus obtaining a composite material
Implementation Method 4
The fabric produced by the method can kill bacteria, adsorb bacteria, dust, particles and moisture etc., and it has strong adsorption ability
Implementation Method 5
In the step (3), bactericide is added into the pure water to prevent cross contamination while sterilizing
