9.6 A schematic diagram illustrating the smoothing effect created by downward air velocity in the steaming zone of a tunnel finisher. Temperature The temperature of the tunnel finisher is critical, and should be uniform throughout the machine. For polycottons, an operating temperature of 155 °C should be maintained. Cottons may withstand a higher temperature. If the operating temperatures are allowed to exceed these guidelines then garments may start to feel harsh and whites may lose their brightness and appear off-white. Even more seriously, there will be a risk of scorching garments and, potentially, a fire hazard. Recycled hot air To improve the cost-effectiveness of the tunnel finisher, the hot air generated during the process is recycled. Due to the velocity of the air flow, lint and dust are blown off the garments. To prevent re-contaminating garments this lint and dust is removed by filters before the hot air is re-used. It is very important to keep these filter screens clean to maintain good airflow and fully utilise the recycled hot air. Quality control check Hot Air Heater Battery Exhaust Fresh Air In As the garments leave the tunnel finisher they will pass through a quality control check to remove any garments that require re-washing or repair. GC8N 22 — Laundry Operations Level 2 Recycled Air
This examination will usually precede sorting the garments into customer batches and directing them to the correct packing procedure. Workwear garments are returned to the customer either on a hanger or folded. Sorting Manual sorting of garments by reading a label or using a key pad is very labour intensive, and to maintain productivity many laundries have introduced sophisticated automatic sorting systems. A single member of staff using a bar code reader or other scanning equipment can be responsible for a full quality check on each garment prior to it being directed to the correct storage rail. These automated sorting systems are designed to keep pace with the productivity of the tunnel finisher. To complete the fully-automated garment finishing production line, the garments that are to be dispatched on hangers will be covered prior to being loaded onto a delivery vehicle. Folding Garment folding is increasingly being carried out by machines. The garments are presented to the operator on a clamped hanger at a suitable height for easy take-off. They are removed from the hanger and placed on the folding equipment. The operator will have to be trained in the correct presentation technique for particular machines, but once the technique is mastered, up to 400 garments per hour can be folded. Garments are stacked in piles by the machine and are then transported by conveyor belt to the packing department. Folding different types of garments from different fabrics in various sizes requires considerable adaptability, and no folding machine has yet been produced that can match the intelligence of the human brain. Only plants that handle large volumes of a limited range of garments usually benefit from an automatic garment folder. GC8N 22 — Laundry Operations Level 2 9.7
