6.10 Tumble-dryer loading % Capacity 100 90 80 70 60 50 40 30 20 10 You should remember that underloading can create as many problems as overloading. An underloaded dryer will not work efficiently or cost effectively. The work will not ‘tumble’ correctly and often will not dry evenly, while using as much energy as a fully loaded dryer. Activity 4 0 Cottons Polycottons Duvets Tick the factors that you think are necessary to successfully dry a load of polyester cotton workwear coats. Correct time set for the drying operation ■ Set machine for cold air inlet only ■ Set machine for an automatic cool down operation ■ Load machine to capacity ■ Clean the air outlet filter screen ■ Load machine to 65 per cent capacity ■ GC8N 22 — Laundry Operations Level 2 Answer sheets p. 6.18
Choice of drying process The choice of drying process will depend on the fabric type and the final finish required on the items being processed. Fully dried works are usually those items that require no further finishing prior to folding and packing. Conditioned works are items that only need a proportion of the moisture content removed before they are completely dried and finished on another machine. Many laundries over-dry conditioned work in the tumble-dryers, as they haven’t taken the full drying capacity of the finishing equipment into account. In other words, they unnecessarily remove moisture by the relatively expensive use of tumble dryers. It costs three times as much to remove dampness from a cotton sheet in a tumbler than it would on a calender, and 25 per cent more to remove moisture from a polyester cotton coat in a tumbler compared to a tunnel finisher.
