Describe how textiles were manufactured in Europe before 1760
scoray [572]

Answer:

Before the 1760s, textile production was a cottage industry using mainly flax and wool. A typical weaving family would own one hand loom, which would be operated by the man with help of a boy; the wife, girls and other women could make sufficient yarn for that loom.

Explanation

The knowledge of textile production had existed for centuries. India had a textile industry that used cotton, from which it manufactured cotton textiles. When raw cotton was exported to Europe it could be used to make fustian.

Two systems had developed for spinning: the simple wheel, which used an intermittent process and the more refined, Saxony wheel which drove a differential spindle and flyer with a heck that guided the thread onto the bobbin, as a continuous process. This was satisfactory for use on handlooms, but neither of these wheels could produce enough thread for the looms after the invention by John Kay in 1734 of the flying shuttle, which made the loom twice as productive.
