Titanium oxide composite fibers and method for producing same
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for internally adding titanium oxide to fibers face challenges in achieving a high fixation ratio without using fixing agents, which limits the whiteness and hiding power of the resulting composite fibers.
Innovation Solution
A titanium oxide composite fiber is created by firmly fixing titanium oxide to fibers using an inorganic binder, such as hydrotalcite, which is synthesized in a slurry containing the fibers and titanium oxide, ensuring efficient and uniform fixation of titanium oxide.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixing agents such as aluminum sulfate or cationic polyacrylamide are used to increase the fixation ratio of titanium oxide in fiber, then the fixation ratio of titanium oxide is improved, but the complexity of the manufacturing process and the use of chemical additives increase
Solution Approach 1:
The invention extracts and eliminates the need for fixing agents from the manufacturing process. By using an inorganic binder that naturally forms during the fiber production process, the patent removes the requirement for additional fixing agents like aluminum sulfate or cationic polyacrylamide, thereby simplifying the manufacturing process while maintaining high fixation ratios of titanium oxide.
Solution Approach 2:
The invention introduces an inorganic binder as an intermediary substance between titanium oxide and fiber. This binder, which may include metal oxides such as zinc oxide, calcium oxide, or magnesium oxide, serves as a mediating agent that facilitates the binding of titanium oxide to the fiber without requiring complex fixing agents, thus resolving the contradiction between fixation ratio and process complexity.
2Reliability
If fixing agents are used to achieve high fixation ratio of titanium oxide, then the whiteness and hiding power are improved, but the cost and environmental impact increase due to chemical additives
Solution Approach 1:
The invention converts potentially harmful chemical additives into beneficial inorganic binders. By using metal oxides such as zinc oxide, calcium oxide, or magnesium oxide as binders, the patent transforms substances that could be considered chemical contaminants into useful binding agents that enhance whiteness and hiding power while reducing environmental impact. These inorganic binders are generally more environmentally friendly than organic fixing agents.
Solution Approach 2:
The invention changes the chemical parameters of the binding system by replacing organic fixing agents with inorganic binders. This parameter change involves using metal oxides with different chemical properties that are more environmentally benign, thereby maintaining the desired whiteness and hiding power while reducing the environmental harm associated with traditional fixing agents.
3Ease of manufacture
If titanium oxide is internally added to fiber without fixing agents, then the manufacturing process is simplified, but the fixation ratio and uniformity of titanium oxide distribution deteriorate
Solution Approach 1:
The inorganic binder acts as an intermediary that enables uniform distribution of titanium oxide without complicating the manufacturing process. The binder provides a matrix or framework that holds titanium oxide particles uniformly throughout the fiber structure, achieving good distribution uniformity while maintaining the simplicity of the manufacturing process.
Solution Approach 2:
The invention creates a composite material system consisting of fiber, inorganic binder, and titanium oxide. This composite structure allows the different components to work together synergistically, where the inorganic binder provides both the binding function and the uniform distribution medium for titanium oxide, thereby achieving good manufacturing precision without sacrificing ease of manufacture.
