Types of steam and correct use Different types of steam are appropriate for different types of fabric, and it’s important to know which is which. Bottom/ironing surface steam This is used for finished knitwear, pile fabrics and in particular heavyweight garments such as camel cloth coats. It is also used for correcting distorted areas such as pocket mouths. Top steam Top steam is used when the press head is closed. The combination of heat and pressure induces the kind of firm and stable finish that is so important on trouser legs and on the lapels and front facings of jackets. Under normal circumstances, only top steam should be used when the head is closed. It is a common error in finishing technique to use top and bottom steam together. Over-steaming should be avoided. Excess steam can drift and relax areas that have already been pressed. Vacuuming The correct use of vacuum sets the fabric and removes excess moisture. Insufficient use of vacuum (a common finishing fault), leads to relaxation and limpness. The garment should always feel cool before moving to the next lay. It is almost impossible to lay down hard and fast steaming and vacuum times owing to the wide variation in boiler plant efficiency, and the condition of individual presses. However, a good general rule is to vacuum for two or three times as long as the steam time. A token touch on the vacuum pedal is absolutely useless. Types of press: the hot head press The hot head press has been developed from the hand iron. The work is placed on a padded table called a buck and a polished, steam heated metal head is brought down and held with some pressure to provide a pressed finish. Various designs of hot head press are seen in commercial laundries, and these include the following. The rotary press The rotary press has been used for many years. It incorporates the principle described above, but has two padded bucks, which rotate alternatively into position beneath the heated head. Air-operated rams make contact with the steam-heated metal head of the press, then lift the buck. This press allows the operator to prepare work on one buck while the other piece of work is under the head. The buck tends to be oblong and long enough to allow cotton coats and boiler suits to be processed efficiently. 7.12 GC8N 22 — Laundry Operations Level 2
Single head press with twin rotating bucks The pressing of a garment on this machine can involve many ‘lays’, as a coat or jacket is pressed in stages with only one thickness pressed at a time. This reduces the risk of creasing and helps to achieve the best quality pressed finish. The following diagram illustrates the time-consuming re-positioning of a coat to achieve the required pressed finish. GC8N 22 — Laundry Operations Level 2 7.13
