old convention of architecture
The fabric is the first visual element in a retractable awning. E ‘is the most spectacular and most vulnerable in retractable awnings. The phenomena of wear, fading, rotting or tissue immediately decreases the overall fitness of a retractable awning, even if part of the tent and accessories are in good health.
As the curtain fabric is so important, a lot of research and technology is oriented towards improving the canopy extinction. There are basically two main areas for fabrics: cotton and acrylic natural skin tone. The key to understanding tissue tends to disappear is to understand both the history of awning technology and modern fabrics.
The demand for outdoor fabrics
Fabric for retractable awnings must endure much abuse of the environment. outdoor fabrics of all types – cotton canvas vinyl or acrylic – face significant wear and harsh conditions. Mechanical damage such as tearing and fraying, and can come from strong wind or the weight of rain, snow, ice or debris. (This is an advantage of retractable awnings, close the curtain that protects against these types of loads.)
Wear adjustment on actual awning, however, has long been the norm:
sun damage and UV
Heating & Cooling
Humidity
Mold
Debris and dust
This causes the fading, tearing and fading. outdoor fabrics, must find a way to resist these environmental factors.
Cotton tents and early
Awnings are an old convention of architecture, dating from the Greeks and Egyptians. In principle, the awnings were made of woven leaves, which went on to linen. In the 19th century, awnings were just “a revival of Europe, both as a practical and stylish window dressing. At that time, awning fabrics are usually cotton canvas, oil painting, which was a little heavy water ‘repellent and used for ships’ sails.
Cotton remained popular until the mid 20th century. Even now, the canvas is still a common (but less popular) of the curtain fabric. It has some advantages as a retractable awning, that it is breathable and has a beautiful visual structure. New scientific advances of the twentieth century, they introduced other therapies for the cotton plants and converted to make it more durable and resistant to mold.
Another advantage for cotton dyeing room. Piece dyeing of cotton – the most common method for external use – create brilliant colors, some of the finest fabrics. In piece dyeing, the cotton is immersed in the warm colors of liquid and then forced through rollers to a uniform color and remove excess.
piece dyeing is not without drawbacks. It is full of bolts of fabric, not the individual son, he is only good for solid colors. For stripes or designs, contrasting colors should be painted, which is not particularly strong and creates a flat, unilateral visual effect. Piece dyeing is also sensitive to environmental wear sunglasses, UV, water and moisture and salt.
