So what is Polycotton?
Polycotton is a hybrid of natural cotton and man-made polyester. The two yarns are weaved together, typically in a ~65% cotton to ~35% polyester ratio, with the idea being that you obtain the best properties of each in the final fabric.
People usually imagine that the old canvas tents were made from cotton, but actually canvas was a hemp-based material – yup, you’ve guessed it – derived from the cannabis plant! Probably best not to smoke it though….
In later years, canvas morphed into a cotton based or linen-based material and was used for many applications from painting to yachting sails.
Benefits of Cotton
Cotton, Hemp, Linen and Canvas – the important common connection between these textiles is that they’re natural and not fabricated in a laboratory by a mad scientist. They offer excellent breathability as a result and have an in-built insulation and warmth which man-made materials like polyester and nylon struggle to replicate.
The breathability of a tent is highly important, because without the ability for moisture to escape, you will get condensation forming inside which can be a fairly unpleasant phenomenon, especially when you get dripped on by your own liquid breath in the morning – not nice!
Cotton and canvas tents adapt well to changing weather conditions by offering coolness in hot weather, and warmness in cold weather. They also have a lovely tactile quality and a reassuring strength and durability which the man-made fibers just don’t possess.
Disadvantages of Cotton and Canvas tents
So if Cotton and Canvas tents were so amazing, why did they fall out of favour? Well, the insulating properties of cotton arise due to the bulkiness and loft of the thread. This leads to heavy tents which are more tricky to transport and take up more space.
They require more maintenance, predominantly because they can absorb alot of moisture and then need thorough drying out to avoid mildew and mould forming when packed away. Also, they can rip quite easily if accidentally snagged.
Finally, cotton and canvas are quite expensive materials, which leads to more expensive tents.
