quality
Whether or not the quality of products and goods improved or degraded after the industrial revolution cannot be fully proven because no record was kept at the time. However, there are many evidence that we can base assumptions on.
Textile
Assuming that we ignore the potential for human errors, the textiles made by spinning machines and looms will not differ in quality comparing to one that is hand produced, but this is not possible. However, when most of the work is semi-automated the room for errors is a lot less than something that is hand-made. Furthermore before the revolution, the only available and economical materials to use were flax and Wool. After the revolution, cotton goods was first imported from India, but after it was eventually banned, so a cotton industry was eventually established using raw materials from colonies.
Agriculture
Before the Industrial Revolution, most village common farms were enclosed and put in the hands of few. This was to encourage the new farming methods and using new implements that will made possible by the change in the iron industry. Furthermore, a farm being owned by a single owner meant that the quality of work and sanitation on the farm was managed better than before when the farm was public
Iron processing
Before the Revolution iron was smelted with charcoal which yielded great quality. However, when the coke furnace was first introduced, the iron was impure and brittle, so the quality was bad and not ideal to use for making goods. However, later improvements improved the quality significantly.
