Multi-Material Surface-Finished Yarn for Functional Textile Coatings

Solution Overview

Problem

Existing fabrics lack multi-functional properties beyond thermal protection, necessitating the development of yarns with additional features to enhance their value and functionality.

Innovation Solution

A surface-finished yarn with alternately arranged inorganic materials, such as metals, metallic oxides, and ceramics, is created by depositing these materials onto the yarn using physical vapor deposition, allowing for the preservation of original properties while imparting new functions like anti-bacteria, thermal insulation, and electric conductivity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional yarns and fabrics are used, then the basic thermal protection function is provided, but additional functional properties (anti-bacteria, thermal insulation, electric conductivity) are lacking

Engineering Contradiction:

Improvefunctional propertiesVSAvoidyarn structure

Core Design Contradiction:

Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The patent applies composite materials by combining organic yarn with multiple inorganic materials (metal particles, metallic oxide particles, ceramic particles) deposited on the yarn surface. This creates a multi-functional composite structure that provides anti-bacterial, thermal insulation, and electric conductivity properties while maintaining the flexibility and comfort of the original yarn.

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The patent implements local quality by alternately arranging different inorganic materials (first material and second material) in alternating sections along the yarn axis. This allows different functional properties to be distributed at different locations on the yarn, enabling multi-functionality without requiring the entire yarn structure to be modified.

Inventive Principle:

Principle #3Local quality

2Adaptability or versatility

If multiple inorganic materials are deposited onto the yarn, then additional functions are achieved, but the manufacturing process becomes more complex

Engineering Contradiction:

Improvemulti-functional propertiesVSAvoiddeposition process

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the yarn into alternating sections and depositing different inorganic materials on each section separately. This segmented approach allows for controlled deposition of multiple materials while maintaining a systematic and manageable manufacturing process.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements local quality by alternately arranging different inorganic materials (first material and second material) in alternating sections along the yarn axis. This allows different functional properties to be distributed at different locations on the yarn, enabling multi-functionality without requiring the entire yarn structure to be modified.

Inventive Principle:

3Adaptability or versatility

If inorganic materials are deposited onto the yarn surface, then functional properties are enhanced, but the original yarn properties may be compromised

Engineering Contradiction:

Improvefunctional propertiesVSAvoidyarn structure

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The patent applies composite materials by combining organic yarn with multiple inorganic materials (metal particles, metallic oxide particles, ceramic particles) deposited on the yarn surface. This creates a multi-functional composite structure that provides anti-bacterial, thermal insulation, and electric conductivity properties while maintaining the flexibility and comfort of the original yarn.

Inventive Principle:

Solution Approach 2:

The patent applies flexible shells and thin films by depositing inorganic material particles on the yarn surface rather than impregnating the yarn core. This surface deposition approach adds functional properties while preserving the original yarn's flexibility, softness, and structural integrity.

Inventive Principle:

Principle #30Flexible shells and thin films
