Natural Fiber Quilted Fabric Protruded Wrinkle Patterns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional quilted fabrics, made of synthetic fibers, lack a good touch feeling and heat insulation effect due to their construction, which prevents the formation of protruded wrinkle patterns along sewing lines, essential for ventilation and insulation.
Innovation Solution
A method involving cotton fabric sheets and a cotton plate, needle-punched to specific thickness and weight, are sewn with a 5-10 mm interval, then processed in a rotary washing machine and hot air dryer to create natural fiber stripe-quilted fabrics with protruded wrinkle patterns, enhancing touch, heat insulation, and ventilation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional synthetic fiber materials are used for quilted fabric, then the fabric can be manufactured with standard quilting processes, but the touch feeling and heat insulation effect are poor
Solution Approach 1:
The patent changes the material parameters from synthetic fibers to natural cotton fibers (30S-60S count), fundamentally altering the fabric's tactile and thermal properties while maintaining compatibility with standard quilting manufacturing processes
Solution Approach 2:
The patent creates a composite structure using natural cotton fabric sheets combined with cotton plates (190-210 g/m2, 2-5 mm thick) as filling material, achieving superior heat insulation and touch feeling while maintaining manufacturability
2Ease of manufacture
If quilting is performed with larger sewing intervals using conventional patterns, then the manufacturing is easier, but protruded wrinkle patterns along sewing lines cannot be formed
Solution Approach 1:
The patent specifies precise sewing interval parameters (5-10 mm) that are narrow enough to create the desired protruded wrinkle patterns along sewing lines, while still maintaining reasonable manufacturing efficiency
Solution Approach 2:
The patent performs preliminary washing and drying treatments before final quilting to pre-shrink and stabilize the natural cotton materials, ensuring that the subsequent quilting process can successfully form the desired protruded wrinkle patterns
3Reliability
If natural fiber cotton materials are used with narrow sewing intervals, then protruded wrinkle patterns with excellent ventilation effect can be formed, but the manufacturing process becomes more complex
Solution Approach 1:
The patent optimizes multiple parameters simultaneously - cotton fiber count (30S-60S), plate thickness (2-5 mm), plate weight (190-210 g/m2), and sewing interval (5-10 mm) - to achieve the desired ventilation and touch properties while keeping the manufacturing process manageable
Solution Approach 2:
The patent utilizes the natural properties of cotton materials to self-form protruded wrinkle patterns during the washing and drying process, eliminating the need for complex additional equipment or processes to create the ventilation structures
