Solution Overview

Problem

Conventional recycled textile fabrics are of low quality, non-durable, and exhibit poor elasticity, tensile strength, pilling, and chemical resistance, contributing to environmental issues due to poor decomposition and greenhouse gas emissions.

Innovation Solution

A woven textile fabric with a 100% cotton warp yarn and 100% recycled multifilament textured polyester weft yarn, with a minimum 35% recycled polyester content, achieving a high thread count and low pilling tendency through specific yarn counts and weaving patterns like twill, satin, or percale, tested for pilling resistance using ASTM D4970 or ISO 12945-2 standards.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If recycled textile fabrics are used to build sustainability, then environmental friendliness is improved, but quality, durability, and performance deteriorate

Engineering Contradiction:
Improveenvironmental impactVSAvoidfabric quality and durability
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent combines recycled polyester fibers with virgin cotton fibers to create a composite fabric structure. The recycled polyester provides structural integrity and durability, while the virgin cotton maintains comfort and aesthetic qualities. This composite approach allows the fabric to meet both sustainability goals and performance requirements that pure recycled fabrics cannot achieve alone.

Inventive Principle:
Principle #40Composite materials

2Manufacturing precision

If high thread count is achieved for better fabric quality, then manufacturing complexity increases

Engineering Contradiction:
Improvefabric qualityVSAvoidmanufacturing complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent specifies precise parameter ranges for yarn counts (30s-80s for cotton warp, 10D-140D for polyester weft) and thread counts (80-1300 PPI) to achieve high fabric quality. By establishing clear parameter boundaries and using standardized yarn specifications, the patent makes high-quality manufacturing achievable through controlled parameters rather than complex processes.

Inventive Principle:
Principle #35Parameter changes

3Object-affected harmful factors

If recycled polyester content is increased for sustainability, then pilling resistance deteriorates

Engineering Contradiction:
ImprovesustainabilityVSAvoidpilling resistance
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent applies different material qualities to different regions of the fabric structure. Recycled polyester (35-65% content) is used primarily in the weft yarns where structural support is needed, while virgin cotton (35-65% content) is used in the warp yarns where surface smoothness and pilling resistance are critical. This localized material assignment allows high recycled content while maintaining surface quality.

Inventive Principle:
Principle #3Local quality
