In the daily operation of laundry shops, the care of PU leather is always a service project. The right dry cleaning treatment not only restores the beauty and comfort but also extends the service life. This article will deeply analyze the three core elements that damage the dry cleaning results of the leathers: fatliquor, time, and temperature, and provide a set of scientific and practical operating guides for industry practitioners.
Dosage of Fatliquor
Fatliquor plays multiple roles in leather dry cleaning: it is both a washing aid and a maintenance component.
Its dosage directly affects the color retention, hand softness, and overall cleaning effect of leather clothing. High-quality fatliquor has strong permeability. It can effectively remove stains and reduce the impact of dry cleaning solvent on leather dyeing. It also greatly improves the hand feel of the clothes.
- In actual operations, it is recommended to continuously add fatliquor during the dryingprocess to make up for the loss caused by the adsorption of leather. Finally, the washed leather clothes should reach the ideal state of being “soft but not sticky, oily but not greasy”. It should be noted that whether for smooth leather or suede, the dosage is roughly the same. Mixing other types of dry cleaning auxiliaries should be avoided as much as possible to prevent badly affecting the results.
Drying Time
The drying time should be adjusted flexibly according to the actual level of stains.
Relatively clean leather clothes: Dry cleaning time is 3 to 5 minutes.
Clothes with severe stains: Dry cleaning time can be extended to 8 to 10 minutes.
Smooth leather garments that only need lining cleaning: Dry cleaning time can be appropriately shortened.
For leather that has hardened due to repeated polishing treatments, the dry cleaning time can be extended appropriately, or a special leather film remover can be used for pretreatment before dry cleaning. This helps achieve better softening and cleaning effects.
Strictly Control Drying Temperature
Drying is the sensitive link of leather care, especially temperature control. People should make sure that the actual temperature of the drying room is not over 45 degrees Celsius. Because there may be an error between the displayed temperature of the equipment and the actual temperature. It is suggested to calibrate the temperature measurement instruments regularly to avoid leather shrinking, hardening, or getting burned.
- Special note:
Raw leather garments (cowhide, sheepskin…) are usually thicker, commonly seen in winter coats or work clothes. They accumulate more dirt and are harder to clean. It is recommended to appropriately extend the cleaning time during dry cleaning and reasonably increase the amount of fatliquor to thoroughly remove dirt and maintain the softness and luster of the leather.
Conclusion
Leather dry cleaning is a task of detail and skill. Only by accurately grasping the three key elements: dosage of the fatliquor, time, and temperature, can the washing effect be guaranteed and the material of the clothes be protected. We hope this article will provide a reference for your laundry shop, help increase the service quality, and win customers’ trust.
