Levi Strauss Replaces Human Sanding With Automated Lasers (bloomberg.com) 237

_Sharp'r_ writes: Stressing jeans used to require 300 to 400 workers with sandpaper all day. Now Levi Strauss does a better job by shooting their new jeans with computer-guided lasers in intricate patterns generated in CAD systems. Along the way, they save water and "will cut the number of chemicals it uses to produce jeans from 1,000 to a few dozen," reports Bloomberg.

Clothing whose materials are only the finest naturally grown, recycled hemp, crafted in the dark by underprivileged, overpaid tibetan monks.

    Imagine managing 300 to 400 people who do nothing for eight to 10 hours but to load a mannequin and then with sandpaper on their hands to begin the destruction process to remove the indigo.

    Do the lasers still damage the fibres or do they just remove the indigo or even just its colour?

    Indigo is a plant chemical that takes a specific chemical reaction to form, and needs special treatment to adhere it to the fibres. The fact that it does not adhere perfectly is what causes the specific worn look on jeans. If the fibres can be kept intact but the indigo selectively removed, you could have a pair of jeans that looks used but also can still be used for a long time.

        Having AI doing coding is completely infeasible at this time, and not even on the distant horizon. It is unclear whether it will ever work and it is quite possible that it will not. However, there is no large need for coders. In fact, there are already far too many coders and most of them are bad. Remove the bad ones and the good ones do not get bogged down in fixing their mistakes and can easily do all coding that is needed. And that will happen sooner or later.

It certainly would raise the per unit profit sold profit, but it would sell fewer jeans. The price represents what the manufacturer believes is the optimal compromise between unit profit and quantity sold.

  • I always used to buy my jeans from Levi's, and many years ago they were some of the most consistently manufactured jeans around - in particular, when most of their manufacturing was done in the USA. Much more recently I went to buy two pairs of (theoretically) identical jeans - same cut, same waist, same inseam, differing only by color - and they could have hardly been less similar when I tried them on. Then I checked the tag and realized one pair was made in South America and the other in Southeast Asia - again on the rack they differed only in color. Yet one was uncomfortably tight to button and the other was so loose in the waist that it would nearly fall off of me without a belt.
