I would guess that to get the names woven in to the material would be very costly. The material used in making up the proposed new shirts is more than likely already used in various shirts which keeps the cost of production down. Can't see any benefits in fans paying sponsorship money if a proportion of that is going to have to pay for a bigger cost in producing the shirt. I would also guess the kit design and the material used in it is already finalised now.
It was done as a one off at Burnley a few years ago, each sponsor paid £1,000 for their name to be on it, it was specially made and worn once
