Americos AFC (Oil & Water Repellent Finish)

Americos AFC (Oil & Water Repellent Finish)
Introduction :
Americos AFC is resistance to water and oil borne stains which is a highly desirable feature for many textile uses including outerwear, home furnishings and industrial fabrics. The excellent water repellency and high degree of oil repellency provided by Americos AFC is durable to washing and dry-cleaning.

Special Features: General Properties :
AppearanceOpaque liquid
TypeFluorochemical emulsion
pH6
Viscosity (25°C)50 cps
Density (25°C)8.8 lbs/gal
Ionic natureCationic
SolubilityMiscible in water

Water and Oil Repellent Finish for Textiles:
Fabric preparation:
For maximum water repellency, fabrics should be free of all sizing agents, wetting agents, alkali and other additives, which may have a tendency to interfere with repellent properties. Fabrics should be well prepared and left slightly acidic for best results.

Silicone defoaming agents reduce oil resistance and their use should be avoided in all preparation stages, including sizing of the warp. Silicone water repellents are also very detrimental. The presence of these materials even in minute amounts makes it practically impossible to obtain a satisfactory oil rating.

Bath make-up :
Americos Olifulant-O-W-992 is an aqueous emulsion that is readily dispersible in water. It is compatible with many resins, catalysts, hand-builders and other finishing products. The order and manner of addition of these products could affect bath stability. Americos Olifulant-O-W-992 emulsion should be the last add to the bath and should be pre-dispersed with an equal quantity of water. It is recommended that bath temperature be in the range of 80°-100°F. Excessive high-speed mixing of the bath should be avoided.

Processing conditions:
Impregnation:
Pad the fabric with Americos Olifulant-O-W-992 using a two or three bowl padding mangle. Cloth that enters the bath should be at room temperature to prevent warming the pad bath. Placing a cooling fan in front of the padding mangle may help this.

Pre-drying: For best results, the impregnated fabric should be pre-dried nearly to 30-40% moisture content before entering the drying chamber and this would increase the process speed. Infrared pre-driers are preferred, but roller type pre-driers or Teflon coated cans may also be used.
Drying :
For fabrics that require heat setting, temperature inside drying chamber may be kept at 365° to 400°F.

Curing: Sixty seconds at 340°F is a typical curing method, however, the optimum time and temperature may vary with fabric type and its blend, GSM and oven characteristics.

Formulations:
Water and oil repellent, durable finish for cotton and cellulosic/synthetic blends.

Americos K255

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:
pH5.5-7.0
Temp40°C-65°C
Dosage0.01%-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.
Compatibility:
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: 
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.
