Fabric with Digitally Controlled Characteristics

Smart overview of the Invention

The patent describes a fabric composed of printed strands, each containing multiple materials with varying characteristics such as color and elasticity. These strands can be printed with differing orientations, allowing for selective control over the fabric's appearance and texture. By rotating the print head nozzle, specific regions of the fabric can be manipulated to exhibit the properties of one material over another.

Field of Application

The fabric is intended for use in various applications, including electronic device covers, wearable technology, and other fabric-based items. These items can benefit from the fabric's attributes, such as sound permeability and durability. The technology aims to overcome challenges related to fabric vulnerability and performance issues in different environments.

Manufacturing Process

The fabric is created using additive manufacturing techniques, where strands are printed onto a support structure like a rotating cylinder. The print head features a digitally controlled rotating nozzle that dispenses materials with different properties through a common aperture. This allows for precise control over the fabric's composition and characteristics across its width.

Strand Characteristics

Printed strands can vary in color, flexibility, and other attributes along their length. The strands may include multiple materials, enabling different segments to display different properties. This digital control over the fabric's characteristics allows for customization in look, feel, and functionality by adjusting the print head nozzle's rotation.

Material Composition

The fabric may incorporate both printed and non-printed strands, potentially combining materials like polymers, metals, and natural fibers. Conductive coatings can be applied to non-conductive strands, and conductive paths can be formed for electrical applications. The fabric can include intertwined or layered strands, utilizing various manufacturing techniques to achieve desired properties and configurations.
