Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for incorporating solid particles into yarns to enhance properties are technically complex and require specific implementation, limiting their effectiveness and efficiency in fields like electrical insulation, thermal insulation, and conveyor belts.
Innovation Solution
Incorporating filler particles, such as boron nitride, alumina, or carbon nanotubes, into the sizing bath during the yarn manufacturing process, allowing them to be dispersed as particulate form within the sizing polymer, which coats the warp yarns, thereby enhancing thermal conductivity and other properties without altering the manufacturing process significantly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If solid particles are incorporated into yarns using existing methods, then fabric properties are enhanced, but the manufacturing process becomes technically complex and requires specific implementation
Solution Approach 1:
The patent combines the filler incorporation step with the existing sizing operation by adding filler particles to the sizing bath. This merging of operations allows filler particles to be deposited on warp yarns during the normal sizing process, eliminating the need for separate filler incorporation equipment and complex manufacturing steps while still achieving enhanced fabric properties
Solution Approach 2:
The sizing bath acts as an intermediary medium that facilitates filler particle deposition on yarns. By incorporating fillers into the sizing bath, the patent uses the existing sizing agent as a carrier to transport and deposit filler particles on warp yarns during the weaving preparation process, simplifying the overall manufacturing system
2Temperature
If filler particles are added to enhance thermal conductivity, then thermal performance improves, but manufacturing cost may increase
Solution Approach 1:
The patent optimizes the concentration of filler particles in the sizing bath to achieve the desired thermal conductivity enhancement while controlling material consumption. By carefully adjusting the filler loading parameter within the sizing bath, the patent balances thermal performance improvement with manufacturing cost considerations
Solution Approach 2:
The sizing operation serves multiple functions simultaneously: it provides the traditional sizing protection for warp yarns during weaving and also incorporates filler particles to enhance thermal conductivity. This multi-functionality eliminates the need for separate filler application steps and reduces overall manufacturing costs by consolidating operations
3Reliability
If filler particles are incorporated into yarns, then fabric properties are enhanced, but the manufacturing process requires significant modification
Solution Approach 1:
The patent merges the filler incorporation function with the existing sizing operation, allowing both functions to be performed in a single processing step. The sizing bath simultaneously provides yarn protection and filler deposition, eliminating the need for separate filler incorporation equipment and process modifications
Solution Approach 2:
The existing sizing infrastructure and equipment are utilized to perform the additional function of filler particle deposition. The normal sizing operation automatically incorporates fillers when they are added to the sizing bath, requiring no additional equipment or significant process modifications while still achieving enhanced fabric properties
4Temperature
If filler particles are dispersed in size, then thermal conductivity improves, but the sizing deposition amount increases
Solution Approach 1:
The patent optimizes the concentration of filler particles in the sizing bath to achieve the desired thermal conductivity enhancement while controlling the amount of polymer deposit. By carefully adjusting the filler loading parameter, the patent balances thermal performance improvement with polymer consumption
Solution Approach 2:
The patent creates a composite sizing composition by dispersing filler particles within the polymer-based sizing agent. This composite material provides both the protective sizing function and the thermal conductivity enhancement, with the filler particles distributed throughout the polymer matrix to improve thermal performance without requiring excessive polymer deposit
