Flame-Resistant Woven Fabric With Distinctive Ornamental Patterns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional protective garments lack a distinctive look that allows users to recognize the quality and properties of the fabric, leading to a need for a fabric that combines excellent properties with a unique appearance.
Innovation Solution
A fabric is developed with a pattern of discrete ornamental designs formed by weaving background and figure yarns, which can include spiral, geometric, or fanciful designs, using materials like aramid and PBO fibers, providing strength, flexibility, and flame resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional protective garments are made with multiple discrete layers using thermally-resistant materials, then fire resistance and protection properties are improved, but the garments become heavy and cumbersome
Solution Approach 1:
The patent combines multiple discrete protective layers into a single integrated fabric structure. The fabric incorporates thermally-resistant fibers, moisture management capabilities, and structural integrity features within one woven construction, eliminating the need for separate layers while maintaining fire resistance and protection properties.
Solution Approach 2:
The fabric uses composite material construction with blends of thermally-resistant fibers (such as aramid, modacrylic, or other flame-resistant materials) combined with other functional fibers. This creates a multi-functional material that provides fire protection, moisture management, and mechanical strength in a single fabric layer.
2Ease of manufacture
If protective garments use standard fabrics from different manufacturers, then production cost and availability are improved, but the garments lack distinctive appearance and quality recognition
Solution Approach 1:
The fabric incorporates distinctive local qualities through its construction - such as specific weave patterns, yarn arrangements, or localized design elements - that create a recognizable appearance. These local quality features allow the fabric to maintain standard manufacturing processes while providing unique visual identification and quality recognition.
Solution Approach 2:
The fabric utilizes color variations, dye patterns, or chromatic features as part of its distinctive appearance. By incorporating specific color schemes, gradient effects, or colored yarns in particular arrangements, the fabric achieves visual differentiation while remaining compatible with standard manufacturing processes.
3Weight of moving object
If the fabric is made lighter to reduce encumbrance, then flexibility and wearer comfort are improved, but fire resistance and protective properties may be compromised
Solution Approach 1:
The fabric optimizes protective properties by changing material parameters - such as fiber density, yarn construction, weave tightness, or material composition ratios - rather than simply increasing weight. This allows the fabric to maintain fire resistance and protection capabilities while achieving reduced weight through efficient material utilization and advanced fiber technology.

AI summary
Fabrics that have a pattern of discrete ornamental designs are disclosed that can be used in numerous applications. In one embodiment, the fabric can be made from flame resistant fibers for use in protective garments, especially firefighting garments. The discrete designs make the fabric readily recognizable that provides an indicia for the excellent physical properties of the fabric. For instance, not only is the fabric lightweight, strong and abrasion resistant, but also has excellent stretch properties in multiple directions, especially in directions diagonal to the warp direction and the fill direction.
