Opal-Finished Fabric Structure for Transparent Multicolor Patterns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional opal-finished fabrics face limitations in expressing complex patterns with multiple colors and clear color tones on both fiber-decomposed and non-decomposed parts, while also struggling with strength and durability issues in the fiber-decomposed areas, which restrict their design and application in various fields.
Innovation Solution
An opal-finished fabric is developed using a combination of nylon and polyester fibers, where the fiber-decomposed part is primarily composed of colored nylon fibers and the non-decomposed part of mainly polyester fibers, with a layered structure and specific weaving patterns like atlas stitch, allowing for independent color expression and enhanced strength through controlled fiber decomposition and dyeing processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If ground dyeing is performed before or after fiber-decomposing treatment to dye the non-decomposed fiber part, then the land part can be dyed with clear colors, but the fiber-decomposed part is restricted to monochrome and pattern expression is significantly restricted
Solution Approach 1:
The fabric is divided into two distinct fiber types with different decomposition characteristics: nylon fibers that decompose to form colored patterns and polyester fibers that remain intact to form the land area. This segmentation allows independent color treatment of each region, enabling multi-color patterns without ground dyeing restrictions.
Solution Approach 2:
Different fiber types are assigned different local qualities: nylon fibers are dyed with acid dyes for the pattern areas while polyester fibers are dyed with disperse dyes for the land areas. This local quality differentiation enables each region to be optimized for its specific function, achieving both clear land colors and vibrant pattern colors simultaneously.
2Ease of manufacture
If dye is added in advance to the carbonizing paste or fiber-decomposing paste to dye directly the fibers in the fiber-decomposed part, then the fiber-decomposed part can be colored, but the dye selection is restricted and stable color tone is difficult to achieve
Solution Approach 1:
The nylon fibers are pre-dyed with acid dyes before the fiber decomposition process. This preliminary action ensures that the color is already embedded in the fibers before decomposition, guaranteeing stable and vibrant color tones in the final pattern areas without relying on dye addition to the decomposing paste.
3Illumination intensity
If a thin fabric is used to achieve transparent appearance in the fiber-decomposed part, then the stereoscopic appearance is enhanced, but the structure remaining on the fiber-decomposed part is liable to suffer decrease in strength and the woven texture may be displaced or raveled out
Solution Approach 1:
The fabric uses a composite structure combining nylon and polyester fibers. The polyester fibers provide structural strength and stability to prevent raveling and displacement, while the nylon fibers provide the desired transparency when decomposed. This composite material approach allows the thin fabric to maintain both transparency and sufficient strength.
4Adaptability or versatility
If separate steps including dyeing step and embroidery step are used to achieve rich design, then the depressed part can be freely dyed clearly and the land part can have free expression, but the positioning of the patterns becomes complicated and productivity decreases
Solution Approach 1:
The invention merges the dyeing process and pattern formation into a single integrated fiber decomposition process. By pre-dyeing nylon fibers and using selective decomposition, both the pattern areas and land areas achieve their final colors in one process, eliminating the need for separate embroidery or multi-step dyeing operations, thereby significantly improving productivity while maintaining design freedom.

Function Achieved in This Case
This approach enables rich color expression and sufficient strength in the fiber-decomposed part, allowing for a highly stereoscopic and transparent appearance without compromising the structural integrity, thus overcoming the limitations of conventional methods and expanding the fabric's application range.
Implementation Method 1
a fiber-decomposing treatment is applied to a cross woven fabric or a blended fabric of synthetic fibers, such as polyester, nylon or the like
Implementation Method 2
the fabric is dyed with an alkali-undecomposable dye for ground dyeing before or after the fiber-decomposing treatment

AI summary
An opal-finished fabric having a stereoscopic pattern is provided, in which both the fiber-decomposed part and the non-decomposed fiber part are rich in color expression, and the fiber-decomposed part having a sufficient strength with a thin material having highly transparent appearance in the fiber-decomposed part. The fabric is an opal-finished fabric obtained with two or more kinds of fibers and formed with a fiber-decomposed part showing a transparent appearance by removing at least one kind of the fibers and a non-decomposed fiber part, in which for solving the problems, the fiber-decomposed part contains mainly nylon fibers, and the non-decomposed fiber part contains mainly colored polyester fibers and non-colored nylon fibers. The non-decomposed fiber part is preferably constituted by a layer containing mainly polyester fibers and a layer containing mainly nylon fibers. The stretchability thereof can be improved by using the fabric further containing polyurethane fibers or weaving the fiber-decomposed part with an atlas stitch structure or a two-needle stitch structure.
