Intermingled Yarn Structure for Cleaning Cloth with Cut Loops
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing yarn for cleaning fabrics with cut loops are inefficient, leading to increased production costs and reduced productivity, while also compromising cleaning effectiveness due to the low resilience of microfibers used in these fabrics.
Innovation Solution
A yarn is created by intermingling first and second yarns with different fineness levels, where the first yarn has a larger fineness for resilience and the second yarn has a smaller fineness for absorbency and rapid drying properties, eliminating the need for yarn twisting and significantly reducing production costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If microfibers are used as yarn during the preparation of fabrics for cleaning cloths, then polishing properties are improved, but cleaning effect is reduced due to low resilience and elasticity
Solution Approach 1:
The patent applies composite materials by combining microfibers (for polishing) with regular fibers of higher fineness (for resilience and cleaning effect) to create a hybrid yarn structure. This composite approach allows the fabric to simultaneously achieve excellent polishing properties from the microfibers and effective cleaning performance from the regular fibers, resolving the contradiction between these two opposing requirements.
Solution Approach 2:
The patent implements local quality by creating a yarn structure where different fiber types (microfibers and regular fibers) are distributed throughout the yarn cross-section. This allows different regions of the fabric to perform different functions: microfibers provide polishing action while regular fibers provide structural resilience and cleaning capability, enabling both functions to coexist in the same fabric.
2Quantity of substance
If microfibers are used as yarn for cleaning fabrics, then absorbency is improved, but sliding properties degrade due to matting and entangling of threads
Solution Approach 1:
The patent uses composite materials by blending microfibers (high absorbency) with regular fibers (maintain sliding properties) in the yarn structure. The regular fibers prevent matting and entangling while the microfibers provide absorbency, allowing the fabric to maintain both high absorbency and good sliding properties simultaneously.
Solution Approach 2:
The patent applies local quality by distributing microfibers and regular fibers throughout the yarn structure, creating localized regions where microfibers provide absorbency while regular fibers maintain the fabric's sliding properties. This spatial distribution prevents the microfibers from matting while preserving their absorbent function.
3Manufacturing precision
If conventional yarn twisting methods are used to produce pile yarn with sheath-core structure, then fabric performance is improved, but production time and cost increase
Solution Approach 1:
The patent extracts the core function of creating a multi-component yarn structure while eliminating the complex twisting process. Instead of winding covering yarn around core yarn through multiple twisting operations, the invention directly produces a blended yarn structure where different fiber types are integrated throughout the yarn cross-section, achieving similar performance benefits with a simplified production process.
Solution Approach 2:
The patent inverts the conventional approach by instead of creating a structured sheath-core yarn through twisting, it produces a blended yarn where different fiber types are uniformly distributed throughout the yarn structure. This inversion of the structural creation method simplifies the production process while maintaining the functional benefits of having different fiber types in the final fabric.
4Manufacturing precision
If conventional yarn twisting methods are used to produce pile yarn, then yarn structure is improved, but production cost increases
Solution Approach 1:
The patent extracts the essential function of creating a multi-component yarn structure while removing the expensive and time-consuming twisting operations. The invention achieves a well-structured yarn with different fiber types integrated throughout by using a direct blending approach during yarn formation, eliminating the need for multiple twisting and heat-treating steps required by conventional methods.
Solution Approach 2:
The patent inverts the conventional yarn production methodology by instead of building up a structured yarn through sequential twisting of core and covering yarns, it creates a blended yarn structure in a single step where different fiber types are uniformly distributed. This inversion dramatically reduces production complexity and cost while achieving comparable or superior yarn structure.

AI summary
The present invention relates to yarn. The yarn of the present invention is characterized in that it is prepared by placing at least one first yarn - which is made of one, or two or more strands of fiber - and at least one second yarn - which is made of one, or two or more strands of fiber - parallel to one another and then performing intermingling that joins the first yarn and the second yarn together by nipping longitudinally, where a fineness of the first yarn and a fineness of the second yarn are different from each other.
