(b) Delicate fabrics may require gentle cleaning methods.
(ii) Type of Dirt or Stain:
(a) The type of stain (e.g., oil-based, protein-based, dye-based) affects the choice of cleaning agents and methods.
(b) Insoluble dirt like mud needs physical agitation, while greasy stains may require detergents or solvents.
(iii) Water Quality:
(a) Hard Water: Reduces the effectiveness of detergents due to the presence of minerals like calcium and magnesium.
(b) Soft Water: Enhances the cleaning process by improving detergent solubility and lathering.
(iv) Temperature:
(a) Warm water helps dissolve grease and oils and increases the effectiveness of detergents.
(b) Heat-sensitive fabrics or dyes may require cold water to prevent damage.
(v) Detergent or Cleaning Agent:
(a) The composition of the cleaning agent (e.g., surfactants, enzymes) determines its effectiveness on specific stains.
(b) Biodegradable or mild detergents are preferred for delicate fabrics or environmental concerns.
(vi) Mechanical Action:
(a) Agitation in washing machines or manual scrubbing helps dislodge dirt from the fabric surface.
(b) Excessive mechanical action may damage fragile fabrics.
3. How are the different sections organised in a commercial or institutional laundry?
Ans: In a commercial or institutional laundry, the workflow is typically organized into distinct sections to ensure efficiency and maintain hygiene standards. The collection and sorting area is the starting point, where soiled laundry is gathered, sorted by type, color, and degree of soiling. This is followed by the washing section, equipped with industrial washing machines designed to handle large loads. Depending on the fabric and stains, specific washing programs are used. Next is the drying area, where dryers or drying rooms process the cleaned laundry. After drying, items move to the ironing and folding section, where specialized equipment like flatwork ironers or garment steamers is used for pressing and finishing. The inspection and mending area is responsible for quality control, ensuring that all items are clean and in good condition. Finally, the processed laundry is sent to the storage and dispatch section, where it is packed and prepared for delivery or redistribution. This systematic organization helps streamline operations, save time, and maintain high standards of cleanliness and care.
