Cleaning article having coated tow fibers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning articles with tow fibers, such as those coated with mineral oil, have limited efficacy in effectively capturing dust and debris due to hygienic issues and inability to reach certain areas, necessitating improved coating formulations for enhanced cleaning performance.
Innovation Solution
A cleaning article featuring a tow fiber bundle coated with a primary mix of castor oil ethoxylate, fatty alcohol ethoxylate, and fatty acid ester, with specific weight ratios, and optionally a secondary coating of mineral oil, integrated into a laminate structure with a carrier sheet for improved dust pickup and surface interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mineral oil is used to coat tow fibers, then the cleaning article can be manufactured with simple coating process, but the cleaning efficacy is less than optimal and hygiene issues arise
Solution Approach 1:
The patent changes the chemical composition parameters of the coating material from traditional mineral oil to a specific composition containing castor oil ethoxylate (20-40 parts), fatty alcohol ethoxylate (60-80 parts), and fatty acid ester (10-30 parts). This parameter change in coating chemistry resolves the contradiction by maintaining effective dust and debris capture while eliminating hygiene issues and excessive residue associated with mineral oil coatings.
Solution Approach 2:
The patent employs a composite coating material composed of multiple components (castor oil ethoxylate, fatty alcohol ethoxylate, and fatty acid ester) rather than a single substance. This composite approach combines the benefits of different materials to achieve optimal cleaning efficacy while minimizing harmful effects, resolving the contradiction between effective cleaning and hygiene concerns.
2Productivity
If traditional tow fiber coatings are used, then the manufacturing process is simple, but the ability to capture larger particles and reach certain areas is limited
Solution Approach 1:
The patent modifies the surface properties of tow fibers by applying a coating with specific chemical parameters (castor oil ethoxylate, fatty alcohol ethoxylate, and fatty acid ester in defined ratios). This changes the surface energy and texture parameters of the fibers, enabling them to effectively capture larger particles and reach into crevices while maintaining manufacturing simplicity.
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 described coating formulation enhances the cleaning article's ability to capture larger particles and improve surface interaction, leading to more effective dust and debris removal while minimizing residue and moisture-related issues.
Implementation Method 1
the tow fiber bundle comprises tow fibers coated with a primary coat mix comprising castor oil ethoxylate, fatty alcohol ethoxylate, and fatty acid ester
Implementation Method 2
castor oil ethoxylate and said fatty alcohol ethoxylate are present at a weight ratio of said castor oil ethoxylate to said fatty alcohol ethoxylate from about 2:1 to about 1:1

AI summary
A cleaning article for cleaning a target surface. The cleaning article has tow fibers attached to a carrier sheet. The tow fibers are advantageously provided with a primary coat mix. The primary coat mix is a mixture of castor oil ethoxylate, fatty alcohol ethoxylate, and fatty acid ester, wherein the castor oil ethoxylate and the fatty alcohol ethoxylate are present at a weight ratio of the castor oil ethoxylate to the fatty alcohol ethoxylate from about 2:1 to about 1:1, and wherein the fatty acid ester and the fatty alcohol ethoxylate are present at a weight ratio of the fatty acid ester to the fatty alcohol ethoxylate from about 5:1 to about 3:1.
