Structured Yarn Coating- Yarn Functionalization for Smart Textiles
This invention describes a spraying process for the structured coating of a yarn with functional materials in a continu-ous process.
Continuous coating
Application of structures on yarns or filaments
Several materials can be pro-cessed at the same time
Use as a stencil
Reduction in process costs
Suitable for the structured coating of yarns using sprayable coating agents or PVD to produce functional yarns or filaments for electronic or active textiles such as electroluminescence, energy storage or sensor technology in textiles. medical technology is also possible as active substances can also be applied. It can be used as a stencil in yarn sputtering systems as an offset coating of two zones of different material can take place both on top of each other and next to each other.
The yarn passes through two coaxially arranged cylindrical stencils, the outer one of which has a slit-shaped open-ing and the inner one a helical one. By rotating the outer cylin-der at a speed adapted to the yarn speed, a ring-shaped struc-ture that is limited in an axial di-rection can be applied to the yarn surface. This is highly advanta-geous for the production of what are known as smart textiles, as electronic components can be produced directly at the level of a yarn. The substances applied in several layers can have different electronic or electrochemical properties and can be used in a variety of ways.
