Managing an On-Premise Laundry
Objective: examining how to manage a laundry within the hotel
While planning the OPL, consider;
Ex. 4, pg 203 - General Care of Linen Fabrics
The laundry cycle includes the following steps;
Ex. 5, pg 205 - The Flow of Laundry Through the OPL
1. flush (1.5 - 3 min): dissolve and dilute water-soluble soil to reduce soil load
2. break (4 - 10 min, optional): a high-alkaline break products is added to loosen soil
3. suds (5 -8 min): actual wash cycle with detergent
4. carryover suds or intermediate rinse (2 - 5 min): removes soil and alkalinity to help bleach
5. Managementbleach (5 - 8 min): kills bacteria, whitens fabric, removes stains
6. rinse (1.5 - 3 min): removes detergent and soil
7. intermediate extract (1.5 - 2 min, optional): high-sped spin removes detergent and soil, after the first rinse step. should not be used after suds step because it could drive soils back into the fabric.
8. sour/softener or starch/sizing (3 - 5 min): starches are added to stiffen cotton fabrics; sizing is added for polyester blends. Starching/sizing replaces the sour /softener step.
9. extract (2 - 12 min): high speed spin removes moisture, length of it depends on fabric types, extractor capacity and extractor speed
1. water: 2 to 5 gallons of water are used for every pound of dry laundry. Other chemicals must be added to help it clean better.
2. detergents: (a) synthetic detergents effective on oil and grease, (b) builders or alkalies are added to “a” to soften water and remove oil and grease, (c) soaps - neutral or pure soaps contain no alkalies, built soaps do.
3. fabric (optical) brighteners: keep fabrics looking new and colors close to original, often pre-mixed with detergents.
4. Managementbleaches: help remove stains, kill bacteria and whiten fabrics. There are two kinds (a) chlorine: used with any washable, natural, colorfast fiber. safe for some synthetics and destroy others. (b) oxygen: is milder. safe for most washable fabrics. works best in hot water and on organic stains. Both should not be used at the same time because they neutralize each other. A bleach’s pH (degree of acidity or alkalinity) and water temperature must be controlled to prevent fabric damage.
5. alkalies: help detergent lather better and keep stains suspended in the water after they been loosened and lifted from the fabric. Also help neutralize acidic stains (most stains are acidic), making the detergent more effective
6. Managementantichlors: used in rinsing to ensure all the chlorine in the bleach has been removed.
7. mildewcides: prevent the growth of bacteria and fungus on linens for up to 30 days. These microorganisms can cause permanent stains that ruin linens. Moisture helps these to grow, that is why, soiled damp linen should not be allowed to sit in carts for long periods, should be dried and/or ironed when they are removed from washers or extractors.
8. sours: are mild acids to neutralize alkalinity in fabrics after washing and rinsing. Detergents and bleaches contain alkali and any residual alkali can damage fibers and cause yellowing/fading, and skin irritation and leave odors.
9. Managementfabric softener: make fabrics more supple and easier to finish, added with sours in the final wash, can reduce ironing, speed up extraction, reduce drying time, reduce static electricity in fabric. Too much can decrease a fabric’s absorbency.
10.starches: give linen crisp appearance, added in the final step in washing.
The choice of OPL machines and equipment is important for the success of the operation. Bad choice of OPL machines and equipment result in;
Preventive maintenance program is essential to the efficient operation of OPL.
Manufacturers and distributors can help train employees about;
Means that the hotel will take care of guest laundry needs. Can be handled in two ways;
1. often quicker
2. promotes more goodwill with guests
3. allow the OPL to handle employee uniforms
4. generates revenue
To efficiently schedule the laundry staff, exec. HK or laundry manager must;
Total number of pounds of linen that the laundry will have to process the next day = the number of expected occupants (covers) ×the average number of pounds of linen used per occupied room (or cover)
