There are 20 questions from basic principles to operational difficulties about dry cleaning<\/b><\/u><\/strong><\/a>\u00a0technology. In this article, we will discuss the first ten questions.<\/p>\n

Q1: What is the Purpose of Washing? <\/strong><\/h2>\n

A1: No matter what kind of clothes are dirty, they should be washed. If the clothes get dirty and are not washed, not only will they be uncomfortable to wear, but they will also affect the appearance of the clothes. The dirt on the clothes even becomes the place where microorganisms grow and reproduce, thereby damaging the clothes and the safety of the people. (The woolen clothes were eaten by insects.) According to the experiment, if a piece of clothing is not washed in time, the strength of the fabric will decrease by 25-30% at an appropriate temperature in just 30 days. If it is washed in time, the strength of the fabric only decreases by about 2%. The difference between washing and not washing is as much as ten times, which shows the importance of laundry.<\/p>\n

Q2: What is Dry Cleaning?<\/strong><\/h2>\n

A2: Dry cleaning is a process that uses organic solvents and mechanical forces to clean clothes. The biggest difference between dry cleaning and water cleaning is the washing medium. Water washing<\/b><\/u><\/strong><\/a>\u00a0uses water and detergents. Dry cleaning uses organic chemical solvents (tetrachloroethylene) and professional dry cleaning equipment to achieve the cleaning effects according to the procedures, which doesn\u2019t need to use water during the entire cleaning process.<\/p>\n

Q3: What are the Advantages of Dry Cleaning?<\/strong><\/h2>\n

A3: 1. Clothes won\u2019t easily be damaged. 2. The oil stains can be removed thoroughly. 3. The colors are protected well. 4. There is no shrinkage and deformation. The clothes are soft, which makes them convenient for ironing. 5. It can disinfect and kill insects. The clothes are not easily damaged by the worms.<\/p>\n

Q4: What is the Applicable Range of Dry Cleaning?<\/strong><\/h2>\n

A4: Generally speaking, garments made of silk, satin, wool, or those with exquisite craftsmanship and dense structure, and garments unsuitable for water cleaning\u00a0require dry cleaning. In contrast, fabrics such as shirts, underwear, and bedding are best cleaned via water cleaning.<\/p>\n

Q5: Why are these 14 Types of Clothes not Suitable for Dry Cleaning?<\/strong><\/h2>\n

A5:<\/p>\n

    \n
  1. Artificial leather (becomes stiff and cracks)<\/li>\n
  2. Pile fabrics (adhesive between pile and base fabric melts, causing large-area pile loss)<\/li>\n
  3. Coated fabrics (become stiff, shrink, and may crack)<\/li>\n
  4. Down jackets<\/li>\n
  5. Wedding dresses<\/li>\n
  6. Garments with high elastic fiber content (lose or reduce elasticity)<\/li>\n
  7. Light-colored pure cotton garments (become soiled or yellowed)<\/li>\n
  8. Printed fabrics (print peels off or bleeds)<\/li>\n
  9. Decorations (non-removable and soluble in dry cleaning solvent)<\/li>\n
  10. Polypropylene garments (become stiff)<\/li>\n
  11. Hard plastic products (including buttons, decorative beads…)<\/li>\n
  12. Paint-decorated accessories (paint chips off)<\/li>\n
  13. Non-woven fabrics (shrink in both dry and wet cleaning)<\/li>\n
  14. Leather garments<\/li>\n<\/ol>\n

    Q6: How Many Types of Dry Cleaning Machines are Currently Available on the Market?<\/strong><\/h2>\n

    A6: The machines are divided into two types according to different recovery systems. One type is open-type dry cleaning machines, the other is fully enclosed dry cleaning machines. The former is relatively inexpensive and uses water as a condensation medium to recover dry cleaning solvent.\u00a0Due to the original temperature of the water, the recovery is incomplete, and the operating cost is high. It also pollutes the air and has been banned in some countries. The latter is relatively expensive, but it has a complete refrigeration recovery system to recover dry cleaning solvent. As a result, the recovery is complete and the cost decreases a lot. It also complies with environmental protection standards and reduces the consumption of dry cleaning solvents.<\/p>\n

    Q7: How Many Steps Should a Complete Dry Cleaning Process have? How Long Does It Take?<\/strong><\/h2>\n

    A7: It should include 7 steps.<\/p>\n

    Step 1: Turn on the power, steam, compressed air, and cooling water of the dry cleaning machine.<\/p>\n

    Step 2: Load the clothes.<\/p>\n

    Step 3: Use dry cleaning solvent.<\/p>\n

    Step 4: Circulation cleaning (two circulation methods can be selected) for 10 minutes;<\/p>\n

    Step 5: Spin dry for 3 minutes<\/p>\n

    Step 6: Dry for 20 to 25 minutes.<\/p>\n

    Step 7: Cool for 5 minutes.<\/p>\n

    It all takes about 50 minutes. The duration is different according to the textures, level of cleanliness, and colors of the clothes.<\/p>\n

    \"dry<\/p>\n

    A8: Should Clothes be Categorized Before Dry Cleaning? How Should It Be Classified?<\/strong><\/h2>\n

    Q8: The clothes should be classified to prevent cross-contamination between clothes during dry cleaning.<\/p>\n

    If the clothes are classified according to colors: white, light white, dark, and red.<\/p>\n

    If the clothes are classified according to thickness: heavy, ordinary, thin<\/p>\n

    The clothes can also be classified by the level of cleanliness.<\/p>\n

    Q9: Can Using Dry Cleaning Solvent Alone Achieve a Good Washing Effect?<\/strong><\/h2>\n

    A9: No. The stains on clothes can be divided into two types. One is the oil-soluble dirt (all kinds of oil stains). The other is the water-soluble stains. (rice and porridge…) Due to its chemical characteristics, the dry cleaning solvents can only remove the oil-soluble stains and have barely any impact on the water-soluble stains. As a result, a dry cleaning auxiliary, detergent concentrate, should be added to the dry cleaning solvent. It removes water-soluble stains\u00a0so that a good cleaning effect\u00a0can be achieved.<\/p>\n

    Q10: Is it True that the Cleaner the Dry Cleaning Solvent is, the Cleaner the Clothes will be Washed?<\/strong><\/h2>\n

    A10: Yes. A darker color of the dry cleaning solvent shows that there are more impurities and deposited pigments, and it is less clean. As a result, the clothes washed will be dirtier. On the contrary, the clearer the color of the dry cleaning solvent is, the cleaner it will be, and the cleaner the clothes washed will be. Especially for the washing of white clothes, the requirements for dry cleaning solvent are relatively high. The dry cleaning solvent should be more transparent.<\/p>","protected":false},"excerpt":{"rendered":"
