Polyamide 10.10 Fiber Reinforcement for Elastomer Shrinkage Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current elastomer products, such as pneumatic vehicle tire belt bandages, face challenges in using environmentally friendly and resource-efficient reinforcement materials that maintain performance, particularly due to limitations with natural fibers like cotton and rayon, which lack consistent shrinkage behavior and are sensitive to moisture.
Innovation Solution
Incorporating polyamide 10.10 fibers, derived from castor oil, which offer high mechanical strength, resistance to chemicals, and low water absorption, allowing for consistent quality and easy integration into existing adhesive systems, replacing petroleum-based materials like polyamide 6.6.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If natural fibers like cotton or rayon are used as reinforcement materials, then environmental sustainability is improved, but product quality deteriorates due to inconsistent shrinkage behavior and moisture sensitivity
Solution Approach 1:
The patent changes the chemical composition parameters of the fiber material from natural cellulose-based fibers (cotton, rayon) to synthetic polyamide 10.10 fibers. This parameter change maintains environmental sustainability by using castor oil as a renewable raw material while achieving consistent shrinkage behavior and moisture resistance required for reliable product performance in belt bandages
Solution Approach 2:
The patent creates a composite reinforcement material by combining polyamide 10.10 fibers with rubber compounds to form a rubberized fabric. This composite structure integrates the beneficial properties of both materials: the renewable, moisture-resistant polyamide fibers provide structural integrity and consistent shrinkage, while the rubber compound provides adhesion and flexibility, together achieving both environmental sustainability and product quality
2Reliability
If petroleum-based materials like polyamide 6.6 are used, then product quality is maintained, but environmental sustainability deteriorates
Solution Approach 1:
The patent changes the raw material source parameter from petroleum-based feedstocks (used in conventional polyamide 6.6) to plant-based castor oil for polyamide 10.10 production. This parameter change maintains the chemical structure and performance properties of polyamide fibers while improving environmental sustainability by using a renewable, biodegradable raw material
Solution Approach 2:
The patent adopts polyamide 10.10 fibers that can be produced from renewable castor oil crops that grow annually, replacing finite petroleum resources. This approach treats the reinforcement material as a renewable resource that can be sustainably replenished, improving environmental sustainability while maintaining product quality
3Object-affected harmful factors
If rayon is used as a non-petroleum-based fiber, then environmental sustainability is improved, but product quality deteriorates due to lack of shrinkage behavior and high cost
Solution Approach 1:
The patent changes the fiber material parameter from rayon (which lacks shrinkage behavior) to polyamide 10.10 fibers that exhibit consistent shrinkage properties similar to conventional polyamide 6.6. This parameter change maintains environmental sustainability through renewable raw materials while achieving the shrinkage behavior necessary for reliable belt bandage performance during tire vulcanization
