Bio Fading / Bio Stone Washing

Slightly worn look of denim are popular now a days. Which can be achieved by process of biofading/stone washing of denim jeans. Special cellulose has replaced the traditional stone washing process where the blue denim was faded by the abrasive action of pumice stones on the garment surface.

Benefits of Bio Fading/Bio Stone Washing:

  1. A small dose of enzyme can replace several kilograms of pumice stones.
  2. The use of less pumice stones results in less damage to garment, machine and
  3. Less pumice dust generate in the laundry environment.
  4. Ecofriendly process and biodegradable waste
  5. Variety of new finishes available as latest fashion trends.
  6. Increase productivity due to machines contain fewer stones or no stones and more garments.

PacZyme offers a range of cellulases for bio fading/stone washing, each with its own unique properties. These can be used either alone or in combination with pumice stones in order to obtain a specific look.

  1. PAC-FadZyme-A/L (Acid Cellulase Bio Fading Enzyme)
  2. PAC-FadZyme-N/L (Neutral Cellulase Bio Fading Enzyme)

PAC-FadZyme-A/L and PAC-FadZyme-N/L
PAC-FadZyme-A/L and PAC-FadZyme-N/L are the products use for Biofading of Denim as well as Sulfur or other reactive dyed garments in wash wheel process.

PAC-FadZyme-A/L and PAC-FadZyme-N/L partially digests excess and protruding yarns, loosening them from the fabric. The stone washing effect is obtained by homogenous removal of the indigo dye trapped inside the fibers by the cooperative action of enzymatic hydrolysis and mechanical agitation of the fabric. This improves softness, luster and drape.

Processing Guidelines

The enzymatic effect depends on nature of fabric, type of process and application parameters. It is advisable to check process parameters like garment load size, liquor ratio, temperature, pH, process time, dosage and rinsing cycles as per need.

Dosage

The dosage can be optimized on basis of trials only and depends upon nature of fabric, type of process, processing conditions and desired level of performance efficacy. The recommended dosages however are 0.5 – 2 % (owg).

Compatibility

It is recommended to test compatibility of PAC-FadZyme-A/L and PAC-FadZyme-N/L with ingredients like wetting agents etc. prior to its use and its applications.

Packing

It is available in 25 KG & 50 KG HDPE Drums.

Storage

Cool & dry conditions are recommended. Extended storage or adverse conditions may lead to higher dosage requirement.

Shelf Life

It can be stored in closed container up to six months at 25°C.

Safety

Enzyme preparation belongs to protein, which may induce sensitization and or cause allergic reactions in sensitive individuals. Prolonged contact may cause minor irritation for skin, eyes or mucous membrane of nose, so any direct contact with the human body should be avoided. If irritation or allergic response for skin or eyes develops, consult a doctor. MSDS is available on request.
