Stone Washing

Cellulase-based enzymes for stone wash treatments at
different temperatures and pH conditions

Denim stone washing (or stone wash) is a finishing process used to give an aged and worn-out feature to garments. Additionally, stonewashing also improves the softness of jeans and denim fabrics.

Pumice stones used in '70 to give a vintage style to garments
Enzymatic denim stone wash through Garmon's products

The process of stone washing began towards the end of the 1970’s, putting denim garments together with the pumice stones into the washing machines.

As the wash drum rotates, the garments are repeatedly pounded and beaten by the stones, abrading the fibers and the indigo color on the denim fabric. The result is a vintage and worn look on brand new garments.

However, the sole use of pumice stone produced many disadvantages:

  • higher amount of sludge from wastewater treatment
  • increased wear of the washing machines
  • higher manual labor to transport and remove the pumice stones from garments
  • added risk of damage to garments

The enzymes produced by Garmon open new possibilities by increasing the variety of achievable finishes while reducing both the environmental risk and the washing machines wear.

Garmon Chemicals' auxiliaries for stone washing gives a natural look to jeans and denim garments, maintaining high contrast on abraded areas without damaging metal parts (buttons, rivets, etc.).

Furthermore, Garmon’s enzymatic stone wash process eliminates all the issues related to the transportation, manual labor and disposal of the pumice stones, reducing the impact on the environment and on the industrial laundries' workers.
