Ali's family moved from the eastern city of Lahore to Swat in the late 1960s as they looked to capitalise on what was then a booming silk trade in the valley known as "Pakistan's Switzerland", renowned for its lush green mountains, waterfalls and streams.
The industry began with smuggled yarn from Afghanistan, with investors drawn to the prospect of cheap raw materials and abundant labour.
It was a rare manufacturing success story in the country's northwest, which has lagged behind Pakistan's main industrial cities in Punjab province and Karachi, the country's financial nerve centre.
Profits were good for the Ali family business -- repairing machinery from the nearly 500 silk-weaving factories in the valley -- until the Taliban took over in 2007.

"I was earning up to 80,000 rupees (USD 754) a month before the Taliban captured Swat," Ali complained outside his workshop and its silent machines.
The Taliban insurgency in Swat began in 2007 and the militants took over for two years until an army operation was launched to reclaim the popular tourist destination.
During Taliban rule, the militants hanged people at crossroads and flogged women. In the army campaign to dislodge them, factories were looted and workers fled.
"Up to 30 factories were completely destroyed during the militancy period," factory owner Ali Muhammad told AFP from inside his premises, full of jammed looms and broken equipment.
Now investors have headed to the relatively safer havens of Karachi and Lahore and large-scale yarn smuggling is a thing of the past, factory owners are losing hope that the industry will ever revive.
Few have the means to restart on their own and confidence is shattered.
