Explanation:

Starch is found in many plants and is the form in which food is stored for future use, just as animals store

fat for use in leaner times.

With rice, wheat & maize, the major sources of laundry starch, the starch is stored in a dry form in the

seeds or ears of the plant and is converted to sugars for energy when the seed germinates in wet soil. With

potatoes and other plants, starch is stored in the root.

When manufacturing starch the source plants are treated to remove all other materials such as husks,

proteins and other impurities which would hamper performance in the laundry environment.

Dry feed to machine

This is the least desirable as it can clog the hopper of a washer extractor and may not disperse well inside

the machine, depositing lumps of starch on the linen which can show up as surface starch after finishing.

Creamed in a bucket

The starch is creamed with a little cold water in the bottom of a bucket by stirring with a stick or hand. It is

then topped up with water and added to the machine. Cheaper, non blended starches are more difficult to

cream than blended lubricated starches and they also settle very quickly after mixing in buckets or tanks.

Mixed in a stock tank

A full 25kg bag of starch is usually mixed in a tank at a maximum concentration of 12.5% (this would

represent 25kg in 200litres). This must be agitated continuously to prevent the starch settling out and

clogging pipes. This is the method used on batch tunnel washers.
