1. Introduction

The client delivers dirty textile to the laundry. The laundry delivers the clean items again to the customer. This chapter deals with the processes in the laundry and the processing route. Here, we will describe standard washing processes without problems such as damaged textile or unremoved stains. After learning the basic principles the laundry process is explained by the different processes like sorting, washing, dewatering, drying, finishing and folding.

2. Professional Laundry Process

For different textile products different laundry processes are required like drying, ironing or finishing. The professional laundry process consist of the following processes:

Figure 1: Example of laundry process

The most common treated textile products in a professional laundry are:

  • Towels
  • Flat wear (linen, bed sheets)
  • Work wear or uniforms
  • Personal garments

3. Sorting

The dirty laundry is delivered by a truck in containers. When entering the laundry process the laundry is registered by recording the items and corresponding customers. How this is indicated varies by company. Sometimes the incoming laundry is also weighed for administration purpose.

Large scale industrial laundries often use a Batch Washer or tunnel for standard items.
Before washing the articles are sorted by the washing processes required for the articles. In addition, the articles are sorted by the different treatment needs, such as drying, ironing or finishing.

In the textile rental business the textile is owned by the laundry. For example: In the linen rental for health care, separation of textiles for different customers is often not necessary. In linen rental for the hospitality (hotels and restaurants) industry customers separation is usually applied. When the laundry is property of the customer itself, the laundry should remain separated from the laundry of other customers.

With linen rental, the laundry bags can be filled by weight, for example up to 50 kg. With personal garment and hospitality linen the laundry bags are not always completely filled, in order to keep the laundry of customers separated.

Corporate clothing or uniforms are washed in wash extractors (or open end machines) or in a batch washer or tunnel. Sorting is done by colour (white and coloured). Corporate clothing is often customized for the specific companies. Garments with specific pollutants can also be cleaned in solvents by dry cleaning.

Figure 5: example of wash extractors (or called open end machines)

Personal garment and coloured textiles are often cleaned in open end machines. White textile is often washed in a tunnel washers. Personal garment often consists of different types of materials that require different washing processes. Personal garment can also consist of delicate items that require dry cleaning, these items should not be washed, but dry cleaned.
