Knit component with differing visual effects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional textiles typically exhibit the same visual appearance regardless of the viewing angle, lacking dynamic visual effects that could enhance aesthetic appeal or provide competitive advantages in athletic settings.
Innovation Solution
A knit component featuring a tubular rib knit structure with distinct visual effects across different areas, achieved by using different yarns (CD-PET, polyamide, and PET) and applying a dye substance with metallized content to create color-shifting properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional textiles are used, then manufacturing simplicity is maintained, but visual appearance remains static and unchanging across different viewing angles
Solution Approach 1:
The patent applies local quality by using different yarns (first yarn, second yarn, third yarn) with distinct properties in different regions of the knit component. Specifically, the first and second yarns are used in a first area to create a first visual effect, while the third yarn is used in a second area to create a second visual effect. This allows the textile to exhibit spatially varying optical properties without fundamentally changing the manufacturing process.
Solution Approach 2:
The patent directly applies color changes by selecting yarns with different optical properties that respond differently to light. The first yarn and second yarn exhibit a first color or visual effect, while the third yarn exhibits a second color or visual effect. This creates dynamic visual appearance that changes with viewing angle or lighting conditions, transforming a static textile into one with adaptive visual characteristics.
2Adaptability or versatility
If multiple yarns with different properties are used to create color-shifting effects, then visual aesthetic appeal is enhanced, but yarn selection and dyeing process complexity increases
Solution Approach 1:
The patent manages complexity by applying local quality principles - using different yarns only in specific areas where visual differentiation is desired. The first area uses first and second yarns, while the second area uses the third yarn. This localized approach allows aesthetic enhancement without requiring all yarns throughout the entire fabric, thus controlling process complexity.
Solution Approach 2:
The patent employs composite materials by combining multiple yarn types (first yarn, second yarn, third yarn) with different optical properties into a single knit component. This composite structure enables the fabric to exhibit multiple visual effects simultaneously, enhancing aesthetic appeal while maintaining a unified garment structure. The composite nature allows different regions to contribute different visual properties to the overall appearance.

AI summary
Aspects herein provide for a knit component having a tubular rib knit structure that extends away from a base portion of the knit component. The tubular rib knit structure includes at least a first portion extending along a longitudinal side of the tubular rib knit structure, where the first portion exhibits a first visual effect at a first area of the knit component and exhibits a second visual effect at a second area of the knit component.
