Etymology

Towards the end of the Middle Ages , the sails of the ships were made from a strong and resistant fabric that was manufactured in the French city of Olonne , near Nantes and on the coast of the Bay of Biscay .

For this reason, such a cloth was initially called olona in Spanish, as it appears in Antonio de Nebrija’s Latin-Spanish Dictionary ( 1495 ), but in Stevens’s Spanish-English ( 1706 ), it already appears in its current canvas form, defined as web of navigation. However, in later dictionaries it appears as alona until the 19th century .

Definitions

According to Free Dictionary

Strong, strong and waterproof fabric, cotton or hemp , specially used for awnings, boat sails, deck chairs, tents, etc.

According to Oxford

Strong fabric with which candles, awnings, tents, etc. are made.

History

Canvas is a thick, smooth, high-strength fabric that has been part of human industry for centuries (it was already used in 3000 BC). Its first application was in candles, also as an awning or tent. The fabric of ancient times was hemp or linen, and it came from China . Eventually, he replaced the wooden panels that served as the surface for the painting. At the beginning of the aeronautics it was used for the construction of hot air balloons and airships , use that still has today.

Physical characteristics

Modern canvas is generally cotton. It differs from other lightweight cotton fabrics, such as denim, by being plain weave rather than twill. The canvas is available in two basic types: plan and “duck”. Duck threads are knitted tighter. The term duck comes from the Dutch word for “cloth”, doek. In the United States, canvas is classified in two ways: by weight (ounces per square yard) and by a numerical classification system with the numbers reversed by weight.

Utility

Modern canvas fabric is found in a variety of industries. It is still used in the manufacture of candles, tents, awnings, tarpaulins and as a surface for paintings. Within each industry, its use has increased. Artists now use the canvas print screen through digital media. Manufacturers use this material in the creation of backpacks, bags, shoes, car covers, trampoline seats and to wrap the panels that artists use for their paintings, creating a more resistant surface. There are artisans who use canvas today to build canoes.

Producing countries

China , followed by India , Pakistan, and Egypt , along with many small Asian republics . Brazil is the largest producer in South America .

Canvas types

Waterproof canvas

A waterproof tarp is a large piece of tough, flexible, waterproof or waterproof material, often a fabric such as a polyurethane- coated canvas or polyester , or made of plastic materials such as polyethylene . Often the tarpaulins have reinforced rings at their corners and on their sides to serve as anchor points for ropes, to tie or fix them.

In the past, cotton tarpaulins treated with tar or wax were used . They were widely used to make ship sails (such as brigantines , cutters , frigates , sailboats) and to protect merchandise from the effects of the elements.
