Sarafast AS NEW LIQ | UV Absorber for polyeste

2. Product Information 

• Sarafast AS New Liq.is a Triazine based dispersion, suitable for High Temperature Exhaust Application, printing and continuous pad-thermosol application.
• It suitable for Dyeing and printing of polyester Fibres, modified polyester Fibres and their blends that are exposed to critical light and heat conditions. This intense light and heat often cause fabric color to fade more quickly and polyester Fibre to weaken.
• The light fastness requirements specified by motor vehicle manufacturers are therefore extremely high, and only carefully selected products can meet them.
• This applies in particular to textiles in the  automotive sector such as upholstery fabrics , interior linings and seat belts.  
• Sarafast AS New Liq. provide outstanding stability against heat and light.

UV absorber

Reduces fibre damage

Counteracts photochemical Fibre and dye degradation, especially on long-term exposure to light and heat

Outstandingly stable to heat and light.

Safe fulfillment of light fastness requirements even after post-setting and molding processes. Fast to sublimation, no tendency to fogging

Full absorption of UV rays hence maximum light fastness, functionality and stability of PES Fibres

In exhaust dyeing processes, the product is completely picked up by the polyester material and builds-up to a high level of UV absorption - thus showing a high efficiency in reducing colour fading.  

Suitable for dyeing in alkaline conditions as well as alkaline discharge printing processes.

Pumpable and easy to handle. Suitable for container transport and storage.

Homogeneous dispersion, even at a high heating rate and under unfavorable dyeing conditions like package dyeing.

Suitable by exhaust method in soft flow, package & jet dyeing machine.

5. Application

Sarafast AS New Liq is used for dyeing and printing textile made from Polyester Fibres, modified Polyester Fibres and their blends that are exposed to extreme light influence. 

Sarafast AS Liq is water dispersion UV absorber for polyester fibber and blends . it can be applied during dying and printing of polyester fabrics by exhaust and thermosol process 

Stir well before removal from the container

1. Exhaust application during polyester dyeing with disperse dyes. 

• Dosage : 1.5-6%(on weight of the fabric) 

2. Thermosol pad application 

• Dosage : 20-60 g/l(50-60% liquor pick-up)

6. Note

• Sarafast AS New Liq. can be applied in presence of carrier, however the carrier residues may impair the light fastness properties of fabric.
• The effects attainable depend on the type of polyester Fibre (texture, amount of delustrant, denier and cross section), the dyes used and the individual shade.
• Sarafast AS New Liq. shows a slightly yellow self-shade in printing and pad-thermosol application. Certain bright shades might be impaired by this whereas on trichromatic systems it could minimize the fading of the yellow component.
