Stone Wash

Stone Wash
Americos Granofil is a Perlite which is introduced by Americos in two categories, one in powder and second in crystal foam. It gives a denim garment a casual look and uniform abrasion on garment without loss in fabric strength. It can be used for wide range of cellulosic fabrics such as cotton, viscose, and tencel.

Though Americos granofil stone wash has various applications but its introduction in garment processing has revolutionized the finishing of cellulosic and blended textile materials. This has been done by the modification of its physical form and making it suitable for garment processing industry. Americos granofil stone wash can be used on wide range of cellulosics as well as blended fabrics such as cotton, rayon, tencel etc. Americos granofil stone wash when applied on garments gives a gentle abrasion without disturbing the typical fabric properties viz., strength, colour and tone. The abrasion results in mild peach finish and removes extra gloss from the fabric to give it a casual look.

Moreover being a light weight material it does not damages the equipment as well as the garments, that is generally the problem in case of pumice stone application. It also has an excellent compatibility with acid cellulase as well as neutral cellulase enzymes as it is recommended to be used with the latter. Since it is not affected by the pH of the bath it could be used in any medium viz. acid, neutral and alkaline. It saves the enzyme dosages and the processing time that further results in saving of various resources like electricity, man power etc.

Americos Granofil is currently available in three variants namely Americos Granofil 1.5G and Americos Granofil 2.4D. Where sold by Americos Granofil 1.5G is developed for light weight garments that weight maximum of 8 oz and Americos Granofil 2.4D for heavy garments that weight 8 oz and above. Americos Granofil 3.8F for powder grade and it works for abrasion on light/heavy garment.

Application Procedure

Americos Granofil is to be added into the bath prior to any other chemicals including enzymes. The liquor ratio can be maintained as per the requirement of other chemicals. The machine should be run for a couple of minutes to ensure proper dispersion of Americos Granofil among the garments. The other chemicals can be then added including the enzymes. Process timings can be adjusted between 50 to 100 minutes depending upon the desired results. And temperature can also be maintained as required by enzymes in specific.

Note: Fine mesh net could be inserted in the machine outlets so that Americos Granofil can be re collected again and also to avoid blockage of drainage lines.

Neutral Cellulose Powder and Liquid Enzyme

Product Introduction:
Americos K255 is a concentrated powder cellulase enzyme which can effectively be used for bio-polishing and denim abrasion of cellulase composed garments. It is a cellulose enzyme preparation produced using genetically modified strain of Trichoderma reesei. The enzyme is designed to be efficient in treating of cellulosic material and is especially suitable for the finishing processes of all types of cellulosic fabrics.

Product Application:
The product is applied in a novel enzymatic finishing process, for cellulose based fabrics, which is known as “Bio-Polishing” as well as creating denim abrasion also known as stone washing effect.

Application Parameters:
pH 5.5-7.0
Temp 40°C-65°C
Dosage 0.01%-0.07%

Final conditions will vary according to fabric type, conditions, as well as customer style preference. 

Dosage Recommendations: 
It is recommended that optimal dosage be defined by experimenting to obtain the desired effects. Customer’s desired affects varies by company so our listed dosage should be used as reference only.
Non Ionic wetting agents, non-ionic surfactants, dispersants, buffering salts, and pumice stone is compatible with Americos K255, but positive testing is recommended prior to all formulations and applications. Contact of Americos K255 with ferric ions should be avoided. 

Inactivation must be carried out after treatment. Either alkaline rinse by raising pH to > 10 for 10 minutes or the use of bleaching agents will terminate the enzyme reaction.
Storage & Handling Precautions:
  • Store in cool place and avoid storing in direct sunlight
  • The shelf life of Americos K255 is one years under recommended storage
