DIRECTIONS INSTRUCTIONS AND SAFETY

   By Stone/Sand washes

   In order to add user or vintage look to denim, stone or sand washes are often used, and volcanic rocks, pumice stones or sand
are added to the garments during washing process.  The heavy abrasion on the garments brings the expected color fading of the
garment fabrics, but may also damage the zipper products to a certain extent.

  Those heavy washes may leave obvious scratching , scraping on the metal surfaces of the zipper components (including elements,
slider, top stop or bottom stop).  The degree of damages may vary depending on the size and ratio of the stones / sand, washing time
and load of garment, etc.  Due to the physical abrasion on the metal surfaces, metal dust may come off from the zipper components,
and when it is mixed with the stone / sand powder or dirt washed off from the garments, it may be accumulated and attached on the metal
surfaces of the zipper.

  When such stainson the zipper chain or zipper parts come in contact with the garment fabrics, it may cause stain migration.
Stain may look more obvious on the lighter color garment. Because those stains are attached on the surfaces of the garment fabrics instead of resulting from chemical reaction, it can be simply removed by washing by organic solvent or detergent.

  In order to prevent the undesirable stain migration on the garment fabrics, the zipper products should be kept away from any direct striking
with hard objects (e.g. stones etc.) during in the garment washes.  To ensure that the zipper is closed and protected under the garment fabrics
throughout the washing processes would help to minimize the stain migration problem.

  Regarding the possible damages on the zipper products due to the harsh treatments in the stone/sand washes, the selection of YZiP® products would be recommended for their higher durability and zipper strength.  For details, please refer to the topic "Why YZiP® products are
recommended for Stone / Enzyme Washes?"
