Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reflective fabrics are limited by their monotonous color palette and low reflection intensity, failing to meet the evolving demands of the garment industry for safer, more aesthetically pleasing, and fashionable clothing materials.
Innovation Solution
A reflective fabric with color printing is developed, incorporating a fabric layer, an elastic resin layer, and glass beads with a reflective layer on their surface, where the glass beads are embedded in a color printing layer, allowing for multicolor patterns and enhanced reflection properties without compromising safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If glass beads are used as reflection elements in reflective fabric, then retro-reflection property is achieved, but color variety is limited to grey or silver grey
Solution Approach 1:
The reflective fabric is segmented into multiple functional layers: glass bead layer for retro-reflection, color printing layer for pattern and color, elastic resin layer for bonding, and fabric layer for base structure. This segmentation allows each layer to independently perform its function without interfering with others, enabling both retro-reflection and color variety.
Solution Approach 2:
The invention adds a new dimension by introducing a color printing layer that works in conjunction with the glass bead layer. Instead of trying to color the glass beads themselves, the solution prints colors on the fabric surface in another dimensional plane, allowing full color variety while preserving the optical properties of the glass beads.
2Reliability
If traditional reflective fabric is used, then safety protection property is maintained, but aesthetic appeal and fashionability are compromised
Solution Approach 1:
The glass beads are pre-embedded in the fabric during the manufacturing process, establishing the safety protection property from the outset. Subsequently, color printing is applied as a preliminary aesthetic treatment before final assembly, allowing both safety and aesthetics to be built into the product systematically.
Solution Approach 2:
The reflective fabric combines multiple materials with different functions: glass beads for retro-reflection, textile fabrics for comfort and drape, elastic resin for bonding, and color inks for aesthetics. This composite structure integrates safety protection and aesthetic appeal into a unified material system.
3Ease of manufacture
If color printing is applied to reflective fabric, then aesthetic appeal is improved, but reflection intensity may be reduced
Solution Approach 1:
The color printing is applied locally on the fabric surface without covering the glass beads. The printing layer is positioned in areas that do not interfere with the retro-reflective elements, allowing color aesthetic appeal in non-critical areas while preserving reflection intensity in areas where glass beads are present.
Solution Approach 2:
The elastic resin layer acts as an intermediary between the color printing layer and the glass bead layer. It allows the color printing to be applied close to the reflective elements while maintaining proper spacing and optical pathways, preventing the ink from directly blocking the retro-reflection.

AI summary
The invention discloses a reflective fabric with color printing and fabrication method thereof, glass beads (5) are planted on its surface by using a thermoplastic PE material as carrier to embed a part of the glass beads into the thermoplastic PE material and project the other part of the glass beads (5) on the surface of the thermoplastic PE material; a film is plated on the surface of projected glass beads to form a reflective layer (4); ink patterns are printed on the surfaces of the reflective layer and the thermoplastic PE material to form a color printing layer (3); resin is evenly coated on the surface of the color printing layer (3) to form an elastic resin layer; the surface of the elastic resin layer (2) is combined with the fabric to form a fabric layer (1); and after forming, the thermoplastic PE material is peeled off from the glass beads to form the product. On the premise of maintaining the reflective effect of reflective material, the invention employs a special printing method to give the material the color diversity, allow the reflective material to be rich in color, give the material wider application and longer service life, and apply this type of material in production of fashionable clothing better.
