Cotfix HF series - a Robust set of dyes for dyeing & Printing

                                                                            Cotfix HF-series

Cotfix HF dyes for cellulosic fibers are a new type of high-fixation fiber-reactive dye based on new chemistry that utilizes a novel reactive group.

Scarlet HF-3G: Scarlet HF-3G is the only one recommended for nylon as well as cotton. It is a very bright scarlet to be used as a straight color or in combination with Yellow HF-R, Orange HF-2GL and Red HF-2B for orange.

Blue HF-RL: Blue HF-RL is a reddish blue with good build-up and high light fastness (co-complex), the company claims. It is best used in a ternary combination with Yellow HF-R or Orange HF-2GL and Red HF-G or Red HF-2B or Brown HF-2RL.

Red HF-2B: Red HF-2B is a bluish red for use in a ternary combination with Yellow HF-R or Orange HF-2GL and Blue HF-RL or Navy HF-B.

Navy HF-G: Navy HF-G is a slightly greenish navy with moderate light fastness. It can be used as a straight color or in a ternary combination for medium to dark shades with Yellow HF-R or Orange HF-2GL and Red HF-G or Red HF-2B.

Brown HF-2RL: Brown HF2RL is a neutral, homogeneous brown for use in a lightfast ternary combination with Orange HF-2GL and Blue HF-RL.

Orange HF-2GL: Orange HF-2GL is a non-phototropic dye for use in a ternary combination for high light fastness with Brown HF-2RL and Blue HF-RL.

Red HF-G: Red HF-G is a brick red. It can be used in an economical ternary combination with Yellow HF-R or Orange HF-2GL and Blue HF-RL or Navy HF-B.

Yellow HF-R: Yellow HF-R is a slightly reddish yellow for use in a ternary combination with Red HF-G or Red HF-2B, Blue HF-RL or Navy HF-B.

• These dyestuffs can be used for exhaust and continuous applications and are suitable for printing as well.
• These dyes require fewer amounts of salt and soda when compared to regular VS and other series.
• These dyes posses outstanding level dyeing and all round fastness properties

Chemicals required for Exhaust dyeing

Note: The shades shown in this electronic shade card are just representative and do not exactly match to actual.

Exhaust Dyeing Method:

Cold-Pad-Batch Method:

Chemical Requirements:

Padding Bath (room Temperature):

Dyestuff = 30 – 50 gpl

Urea       = 100 gpl

Caustic soda 38°Be = 10ml/litre

Soda ash = 20 gpl

Glauber Salt = 30 gpl

Pad the RFD fabric at room temperature with 70% pickup, batch and cover thoroughly with polyethylene paper and keep it rotating for 4 to 8 hours according to depth and dyestuff selected for padding.

Do cold and hot washes followed by neutralization and soaping.

 

Cold-Pad-Dry-Pad-Steam:

Chemicals required:

Dyestuff = x gpl

Wetting agent = 2 – 4 gpl

Anti-migration agent = 5 – 10 gpl

Mild oxidant = 5 – 10 gpl

Dry at 100 to 120°C

Chemical Pad:

Steam in saturated Steam at 101 – 105°C for 45 – 60 seconds
