Opal-Finished Fabric Composition for Transparent Multi-Color Patterns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional opal-finished fabrics face limitations in expressing complex patterns with multiple colors on both fiber-decomposed and non-fiber-decomposed parts, and they often suffer from reduced strength in the fiber-decomposed area, which affects their transparency and durability.
Innovation Solution
An opal-finished fabric is developed using a combination of nylon and polyester fibers, where the fiber-decomposed part is mainly composed of colored nylon fibers and the non-decomposed part is made of layers containing mainly colored polyester fibers and non-colored nylon fibers, with a specific woven structure and dyeing process to achieve rich color expression and sufficient strength.
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-fiber-decomposed 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 invention divides the dyeing process into two independent segments: (1) dyeing the non-fiber-decomposed part with ground dye before fiber decomposition, and (2) dyeing the fiber-decomposed part with fiber-decomposable dye after decomposition. This segmentation allows each part to be dyed with appropriate dyes independently, enabling multi-color patterns with clear color tones on both the land and depressed parts without mutual interference.
Solution Approach 2:
The invention performs ground dyeing of the non-fiber-decomposed part as a preliminary action before fiber-decomposing treatment. By dyeing the land part first with dyes that are not decomposed by the fiber-decomposing agents, the subsequent fiber decomposition does not affect the color of the land part, ensuring clear color tones and enabling subsequent multi-color pattern printing on the depressed part.
2Shape
If fiber-decomposing treatment is applied to create transparent appearance in the fiber-decomposed part, then stereoscopic appearance is enhanced, but the structure remaining on the fiber-decomposed part suffers decrease in strength and may be displaced or raveled
Solution Approach 1:
The invention applies local quality by using different fiber types in different locations: the depressed part is made of fiber-decomposable fibers (cotton, rayon, etc.) that are removed to create transparent appearance, while the land part is made of fiber-undecomposable fibers (polyester, nylon, etc.) that maintain structural strength. This local differentiation allows the fabric to simultaneously achieve transparent appearance in the pattern areas and sufficient strength in the structural areas.
Solution Approach 2:
The invention uses composite materials consisting of two or more different fiber types with complementary properties. The fabric combines fiber-decomposable fibers (for transparent pattern areas) with fiber-undecomposable fibers (for strength-maintaining land areas). This composite structure enables the fabric to achieve both transparent appearance in the fiber-decomposed part and sufficient strength to prevent displacement or raveling.
3Adaptability or versatility
If different fiber-decomposing pastes are printed on one fabric to dye the fiber-decomposed part with multiple colors, then color variety is increased, but the boundary between pastes is difficult to control and only monochrome is practically achieved
Solution Approach 1:
The invention introduces a barrier layer as an intermediary between different fiber-decomposing paste patterns. This barrier layer prevents the pastes from mixing at boundaries, allowing clear multi-color patterns to be formed on the fiber-decomposed part. The barrier layer acts as a mediator that enables precise boundary control while maintaining the ability to apply multiple colors through different fiber-decomposing pastes.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach allows for a stereoscopic pattern with rich color variation on both parts without color interference, while maintaining sufficient strength and transparency in the fiber-decomposed area, enabling a wide range of applications including sports clothing and underwear.
Implementation Method 1
a cross woven fabric or a blended fabric of synthetic fibers, such as polyester, nylon or the like, and vegetable fibers, such as silk, rayon or the like, is printed with a carbonizing paste using sulfuric acid, aluminum sulfate or the like, or a strongly alkaline fiber-decomposing paste, whereby at least one kind of the fibers constituting the fabric is removed in the printed part to form a see-through pattern

AI summary
An opal-finished fabric having a stereoscopic pattern is provided, in which both the fiber-decomposed part and the non-fiber-decomposed 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-fiber-decomposed part, in which for solving the problems, the fiber-decomposed part contains mainly nylon fibers, and the non-fiber-decomposed part contains mainly colored polyester fibers and non-colored nylon fibers. The non-fiber-decomposed 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.
