Difficult to answer.
I can tell we have in our archives cotton dated back ’60, which apparently is better quality than the cotton we have today. At that time the cotton were picked up by hands, and majority of the processes were made by hands. Now the technology reached standards of quality for sure superiors, but the quality of the raw material (maybe the pollution, maybe the quest of the profit, maybe too much production ?) seems to be lower.
The same for the other yarns (more or less). Keeping in mind that the new rules (Reach regulation first) changed the chemicals can be used to dye the yarn (and this is good for sure for the health of the consumers), the color, for example, can’t be fixed as it can be in the past.
Different is the impact of the technology on production. New machines are for sure more performing than the old ones. The difference is in the process after the production (the famous 12 “by hands” steps we have to complete the production and finishing process). We do exactly as they were made 40 years ago. More expensive for sure, but not comparable in terms of quality to the modern technologies on the market.
Maybe because trough the hands we put also our heart in our products..
