in the 1300s, in Manchester, and the cotton is now threatened other goods that flax and
wool on the market.
For a while it was even forbidden to use cotton goods, but progress could not be stopped.
Towards the end of the 1700s, production was greater than ever, with the right
Manchester city center.

spinners and weavers in Sweden.
But even then guessed that a couple 100 years later it would be the most used tool worldwide.

much depends on the plant that grows in the country, tanguisplantan. It has long
fibers and is much whiter than usual, and then you need nothing
bleach.
In the jungle grows cotton plants that are naturally colored in green and brown,
and it seeks to cultivate them, so that the dye should be
superfluous.

biological pesticides, and only hand-picking. One way to combat
insects is through so that a line of any other crop and then. One
also using insect-eating wasps, which kills the pests, but

Linet was formerly one of our most important cultivated plants.
The cultivation of flax in Sweden declined sharply in the late 1800s, when the 1860 century is estimated to have involved over 16000hektar, which in 1916 had decreased to about 900hektar.
Linhantering is very difficult, flax will be grown, harvested, dried, scratched (seed pods scratched off), digested (the stalks are soaked up to release fibers), full of fighting (crushed), undergo such slaughter and häcklas (linfibern cleared of firewood and short fibers) finally spun and woven to produce linen fabric.
To obtain 300kg linen required 6 tonnes unscratched straw.
Flaxseed is used among other things as anti-constipation and is sometimes included in the bread.
