What Is Woven Fabric?
A woven fabric is a textile formed by interlacing two or more threads at right angles to one another, often created on a loom. It is made of many threads woven on a warp (lengthwise yarns) and a weft (crosswise yarns).
Properties of Woven Fabric
- Yarn Properties: Yarn count, twist, fiber fineness, and stiffness affect fabric strength, drape, and overall performance.
- Fabric Density: The number of warp and weft yarns per unit area, known as fabric density or cover factor, impacts properties like air permeability, moisture management, and dimensional stability.
- Crimp: The waviness or crimp in the yarns caused by interlacing affects fabric properties like extensibility, shear behavior, and surface roughness.
- Weave Factor: The ratio of the length of yarn in a fabric to the length of the fabric itself, known as the weave factor, influences fabric properties like thickness, weight, and porosity.
Types Of Woven Fabric
- Plain weave: Warp and weft threads interlace in a simple criss-cross pattern, resulting in a balanced, sturdy fabric.
- Twill weave: Weft threads pass over one or more warp threads, creating a distinctive diagonal pattern and increased durability.
- Satin weave: Weft threads float over multiple warp threads, producing a smooth, lustrous surface.
- Jacquard weave: Manufacturers create complex patterns by selectively raising and lowering warp threads, which enables intricate designs.
Applications of Woven Fabric
Recreational and Outdoor Applications
Manufacturers widely use woven fabrics in recreational applications, including trampolines, sports fields, and pool covers. Their woven structure allows water permeability while providing strength and dimensional stability. Fabrics with different yarn geometries can achieve high shade (blocking ≥99% light) while permitting high water flow rates (5-75 gallons/sq.ft/min), making them suitable for pool covers.
Industrial and Construction Applications
Woven fabrics find extensive use in industrial applications like truck covers, fencing, windscreen enclosures, sand blasting, weed control, and debris mats. In construction, they are employed for filtration, drainage, erosion control, soil reinforcement, paving, stabilization, leachate collection/removal, and geotextiles. The woven structure provides strength, permeability, and reinforcement properties required for these demanding applications.
Apparel and Textile Applications
Manufacturers widely use woven fabrics in apparel, tailoring their properties for various applications. For linings, fabrics with false-twisted and crimped yarns provide air permeability, slipperiness, and refreshing feel, enhancing comfort. Manufacturers use woven fabrics for garments, plush toys, home textiles, and decorative fabrics, taking advantage of their versatile fiber composition and weave patterns.
Filtration and Separation Applications
The porous nature of woven fabrics makes them suitable for filtration applications in various industries. Manufacturers use them as filters for air, water, fuel, oil, and other liquids, and for pharmaceutical media purification and chromatography. Engineers can tailor the fabric properties to capture specific particle sizes or separate components based on application requirements.
Emerging Applications
Researchers are exploring woven fabrics for advanced applications, including tissue scaffolds, bioreactor scaffolds, battery separators, fuel cell membranes, and artificial leather laminates. Their unique properties, combined with the ability to engineer the fabric structure and composition, open up new possibilities in diverse fields like biomedical, energy, and composites.
