Warp-Knitted Fabric Structure for Breathability and Opacity

Solution Overview

Problem

Existing sports/leggings fabrics are either too thick and stifling or too thin and transparent, failing to provide both breathability and privacy during exercise.

Innovation Solution

A breathable and non-transparent warp knitted fabric is developed, using a combination of inelastic and elastic yarns knitted in a specific warp knitting structure with an empty threading method, which balances breathability and anti-see-through performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If fabric gram weight is increased to more than 180 gsm, then anti-see-through performance is improved, but breathability deteriorates and fabric feels stuffy

Engineering Contradiction:

Improveanti-see-through performanceVSAvoidbreathability

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies local quality by using different yarn types (elastic and inelastic) and different structural densities in different regions of the fabric. The elastic yarn provides stretch and comfort in specific areas, while the inelastic yarn with its specific structure provides breathability and anti-see-through properties in other areas, creating a balanced overall performance

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent uses composite materials by combining elastic yarn and inelastic yarn in a warp knitting structure. This composite approach allows the fabric to simultaneously achieve breathability from the inelastic yarn structure and elasticity/comfort from the elastic yarn, while maintaining anti-see-through properties through the combined structural effect
