BLASTING SAND

Introduction :
Americos Aluminum oxide is made from bauxite. Mixture of bauxite is electrically fused at high temperature in an arc furnace and Americos Aluminum oxide is thus produced. Americos Aluminum oxide has brown color, high hardness and great toughness.

The abrasive tools made of aluminum oxide are suitable for sand blasting for Denim, Grinding carbon steel, normal alloy steel, malleable cast iron and hard bronze.

It is ideal for sand blasting for Denim fabric because of less iron content. Due to very less iron content, damage to fabric is very less compared to any ordinary aluminum oxide. It can work at very high pressure, which is a major requirement for high production.

Introduction
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.

Typical Dosage Table

S. No.	Fabric Type	Dosage (Gm/Kg of Garment)
1	Denim 03.0 OZ - 06.5 OZ	080 - 110
2	Denim 07.0 OZ - 12.5 OZ	100 - 120
3	Denim 13.0 OZ & above	125 - 150
4	Cottons 03.0 OZ - 06.5 OZ	070 - 080
5	Cottons 07.0 OZ - 12.5 OZ	075 - 090
6	Cottons 13.0 OZ & above	100 - 125

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.

Introduction
Americos supplies of all types and grades of pumice stone. For textile general grade are 1-3 cm, 2-4 cm, 3-5 cm and 5-7 cm. It is pure white and leaves very little waste when used, compared to those of other stones, thus making sabay Pumice recognized and demanded by the end users in many markets of the world.

There are three types of pumice products, which Americos supplies. The first is the micronised pumice powder, from 0 to 160 microns. The second is the pumicite (mainly for construction and horticulture purposes) from 3-8 mm to 15-20 mm. The third is the textile graded as 1-3 cm, 2-4 cm, 3-5 cm and 5-7 cm.

Americos supplies following types of stones :

• 3-8 mm Pumice Stone double washed, three times tumbled
• 1 cm standard Pumice Stone double washed, three times tumbled
• 1-2 cm/ 1-3 cm Pumice Stone double washed, three times tumbled
• 2-3 cm/2-4 cm Pumice Stone double washed, three times tumbled
• 3-5 cm/ 5-7 cm pumice stone double washed, three times tumbled
• 3-8 cm Pumice Stone double washed, three times tumbled
