Sarafast SUN PES | UV Absorber for polyeste

2. Product Information 

• Sarafast SUN PES is Triazine based dispersion. Suitable for Dyeing and printing of textiles for sun protective clothing.
• To improve the sun screening properties of items such as children's and baby wear, open-air sports wear (e.g. jogging, football, tennis, golf, sailing, etc.), beach, swim and leisure wear (T-shirts, shirts, blouses, hats, etc.), agricultural work wear, and uniforms (military, post office, police, school, etc.) 
• To improve the sun screening properties and stability to light of technical textiles such as tenting, roofing, awning and parasol fabrics, other fabrics used to provide shadow, shade and household textiles such as blinds.
• Sarafast SUN PES 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

Low amounts applied on polyester textiles give maximum and durable sun protection.

UPF 50+ ensured on textile fabrics of appropriate construction.

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

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 unfavourable dyeing conditions like package dyeing.

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

5. Application

Sarafast SUN PES UV absorber is added to the liquor at the start of the dyeing cycle and applied by the HT exhaust or pad-thermosol method. 

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

6. Note

• Sarafast SUN PES 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 SUN PES 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.
