Linen & Laundry PT 2.pdf

  1. 1. LINEN AND LAUNDRY
  2. 2. TYPESOFLAUNDRY 2 types of laundry operation : On-premise-laundry (OPL),and Contract-out-laundry (COL) 1) On-premise-laundry (OPL) Located in the hotel premises. Owned by the hotel. The laundry department staff is employed by the hotel.
  3. 3. AdvantagesanddisadvantagesofOPL: ADVANTAGES DISADVANTAGES Complete quality control Linen last longer than COL No delivery/transportation problem Capital assets Need a lot of space Very costly to starting up (machine are expensive) High running cost (pay for utilities and salary) Required technical expert (to handle washing machine and dryer, others)
  4. 4. 2) Contract-out-laundry (COL) Located out of the hotel premises. Not owned by the hotel. The laundry department staff is not employed by the hotel. Must signed contract between hotel and the outside company.
  5. 5. AdvantagesanddisadvantagesofCOL: ADVANTAGES DISADVANTAGES Space does not have to be found More economical Save labour cost No capital outlay Little technical expertise required. Less control over standard Delivery & collection problem Expensive Need a good system of stock control, difficult to manage the stock (par level)
  6. 6. Factors to be considered for planning OPL What is the maximum amount of laundry (output) the OPL would be expected to handle? How much space should be allocated to the OPL? How many equipment is required? Manpower required to operate the laundry efficiently has to be considered carefully. Proper operation time has to be planned in order to meet the laundry demands of the hotel.
  7. 7. FlowofLinensthroughtheOPL The laundry cycle includes the following steps; collecting soiled linens; never use linen for any cleaning purposes transporting soiled linens to the laundry; hand-carry/cart/linen chutes sorting; by the degree of soiling (lightly, moderately and heavily soiled) and by the type of linen (fibers, weaves, colors and categories); important for the right temperature and formulas
  8. 8. D.washing;weigh the linen, and consider (1) time needed, (2) temperature - 83 to 88 centigrade for oilysoils,72 for heavy soils,60 for kitchen rags and linen, (3) agitation (4) chemicals -include detergents, bleaches, softeners, etc. wash cycles includes the following steps; flush (1.5 - 3 min):dissolve and dilute water-solublesoil to reduce soil load break (4 - 10 min, optional):a high-alkaline break products is added to loosen soil suds (5 -8 min):actual wash cycle with detergent carryover suds or intermediate rinse (2 - 5 min):removes soil and alkalinity to help bleach
  9. 9. bleach (5 - 8 min):kills bacteria, whitens fabric,removes stains rinse (1.5 - 3 min):removes detergent and soil 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. 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. extract (2 - 12 min):high speed spin removes moisture, length of it depends on fabric types, extractor capacity and extractor speed
  10. 10. chemicals:a chemical needs depend on (1) the types of linen it uses and (2) the soiling conditions encountered. Commercial OPL uses more alkali to enhance the cleaning power. Major chemicals used in the laundry; water:2to 5gallons of water are used for every pound of dry laundry.Other chemicals must be added to help it clean better. detergents: (a) synthetic detergents effective on oil and grease, (b) builders or alkalies are added to to soften water and remove oil and grease,(c) soaps - neutral or pure soaps contain no alkalies,built soaps do. fabric (optical) brighteners: keep fabrics looking new and colors close to original, often pre-mixed with detergents.
  11. 11. bleaches: 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 becausethey neutralize each other. pH (degree of acidity or alkalinity) and water temperature must be controlled to prevent fabric damage. 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
  12. 12. antichlors: used in rinsing to ensure all the chlorine in the bleach has been removed. 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. 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.
  13. 13. fabric 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 absorbency. starches: give linen crisp appearance,added in the final step in washing. E.Extracting and drying; removes excess moisture through high-speed spin, reduces the weight of the laundry, makes it easyto lift,reduces drying time.
  14. 14. F.finishing; give sthelinenacrisp,wrinkle-free appearance,mayrequire onlydrying(include towels,washclothsand someno-ironitems)or includeironing(sheets, pillowcases,tablecloths, dampnapkins). folding;time consuming when done manually; inspect the linen and reject stained,and torn items. storing;post sorting and stacking, separates any linen types and sizes that were missed in pre-sorting,allowing to rest on shelves for 24hours. transferringlinensto use areas;via clean carts
