The term "Calendered" in the textile industry refers to a finishing process that involves passing fabric between heated rollers or cylinders under pressure. This process aims to improve the fabric's surface smoothness, luster, and overall appearance. Calendering has a long history and has been used for centuries to enhance the performance and aesthetic qualities of textiles.

History and Origin

The process of calendering can be traced back to ancient civilizations, where fabric was smoothed and polished using stone or wooden tools. However, the modern calendering process began to emerge during the Industrial Revolution in the late 18th century. Initially, the calendering process was performed manually, but with advancements in technology, it became mechanized and more efficient.

Types of Calendering

Calendering can be classified into various types based on the desired effect and the characteristics of the fabric:

1. Hot Calendering: In hot calendering, fabric passes through heated rollers, which can reach temperatures up to 200 degrees Celsius. This process helps to smooth the fabric surface, enhance its luster, and improve its drape. Hot calendering is often used for fabrics like cotton, linen, and synthetic blends.
2. Emboss Calendering: Emboss calendering involves the use of engraved rollers to impart a pattern or texture onto the fabric surface. This process creates a three-dimensional effect, adding visual interest and enhancing the fabric's decorative appeal.
3. Glazing: Glazing is a type of calendering that involves the application of a starch or resin-based finish on the fabric surface. This process creates a glossy or polished appearance and adds stiffness to the fabric, making it suitable for applications like tablecloths and curtains.
4. Moire Calendering: Moire calendering is a specialized technique used to create a watermark-like pattern on the fabric surface. By passing the fabric through engraved rollers, a rippled or wavy effect is achieved, enhancing the fabric's visual appeal.

Tips in Handling Calendered Fabrics

When working with calendered fabrics, it is important to keep a few tips in mind to maintain their quality and appearance:

1. Handle with Care: Calendered fabrics can be delicate, so it is essential to handle them gently to avoid creasing or damaging the smooth surface.
2. Wash with Care: Follow the care instructions provided by the manufacturer when washing calendered fabrics. It is recommended to use a gentle cycle and avoid harsh detergents or bleach.
3. Avoid Ironing: Calendered fabrics are already smooth and pressed, so ironing is usually unnecessary. If needed, use a low heat setting and a pressing cloth to protect the fabric.
4. Store Properly: Store calendered fabrics in a cool, dry place, away from direct sunlight, to prevent discoloration or damage.
