Twisted Yarn Industrial Textile Slanted Surface Washing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial textiles used in web processing machines tend to accumulate dirt and fibers, leading to diminished properties and the need for frequent washing, which is inefficient due to the perpendicular surfaces that hinder fluid penetration and dirt removal.
Innovation Solution
The industrial textile features twisted machine direction yarns with slanted surfaces, allowing fluid to penetrate deeper and mechanically loosen dirt, combined with transverse grooves for improved washing and drying efficiency, and a unique structure with high contact points and low surface contact area to enhance cleaning and support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the industrial textile has perpendicular surfaces for supporting fibre web, then it provides stable support structure, but fluid sprays cannot penetrate effectively causing poor washing efficiency
Solution Approach 1:
The machine direction yarns are twisted to create slanted, curved surfaces instead of perpendicular flat surfaces. This curvature allows fluid sprays to penetrate along the slanted surfaces into the textile structure, improving washing efficiency while maintaining structural stability through the twisted yarn configuration
2Stability of the object's composition
If the industrial textile accumulates dirt and fibres on its surfaces, then it maintains initial structural integrity, but its functional properties diminish requiring frequent washing
Solution Approach 1:
The slanted surfaces created by twisted yarns prevent dirt and fibres from adhering effectively, as the curved geometry does not provide flat accumulation surfaces. This reduces dirt buildup and maintains functional properties longer, reducing washing frequency and operational downtime
Solution Approach 2:
The slanted surfaces that initially seemed to reduce structural stability actually improve washing efficiency by directing fluid penetration. The twisting that creates slanted surfaces converts the potential harm of reduced flat support area into the benefit of enhanced fluid access and reduced dirt accumulation
3Ease of operation
If fluid sprays are used to wash the textile, then cleaning capability is provided, but the perpendicular surfaces cause fluid to bounce off rather than penetrate
Solution Approach 1:
The slanted curved surfaces of the twisted yarns redirect fluid spray energy into the textile structure rather than allowing it to bounce off perpendicular surfaces. This improves fluid penetration and washing effectiveness while reducing energy loss from spray deflection
Applied Scientific Principles
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 design enhances washing efficiency by directing fluid sprays effectively through the textile, reduces dirt accumulation, and facilitates air drying, thereby extending the operational life and maintaining the textile's properties.
Implementation Method 1
fluid sprays hitting the twisted machine direction yarns are directed further from the sloping surfaces into the structure of the textile
Implementation Method 2
The structure may also allow the slanted machine direction yarns to move relative to the cross machine direction yarns thereby causing mechanical loosening of dirt
Implementation Method 3
facilitates air drying

AI summary
An industrial fabric is formed of several machine direction (MD) yarns and several cross machine direction (CMD) yarns. The MD-yarns are twisted relative their longitudinal axis so that the twisted yarns have sloped surfaces at least on a web side surface (P) of the textile. The textile is usable in paper machine, pulp machine or filtering machine.
