> GO FOR SUCCESS BEZAKTIV GO

Reduction of water and energy consumption as well as the amount of salt released into our ecological systems are global challenges that decide over the future of the current and future generations.

The amount of water and energy consumed during conventional dyeing is tremendous. In recent years vigorous attempts have been made to save water and energy, especially by reducing the number and temperature of the rinsing baths. This approach has been consistently contin-ued with the development of the colour-inten-sive BEZAKTIV GO dyes. The new dye tech-

nology enables the revolutionary GO process with even lower temperatures during dyeing and rinsing. 40 °C rinsing baths are sufficient for most dyeing applications!At the same time the process time is reduced considerably as fewer rinsing baths are re-quired at a lower temperature. Productivity is enhanced as a result without any expensive investments.

Only small amounts of hydrolysate are pro-duced during the use of BEZAKTIV GO dyes which can be easily washed out. The use of

COTOBLANC SEL in the second rinsing bath also improves the rinsing efficiency further.

> BEZAKTIV GO DYES IN THE COLD PAD-BATCH PROCESS

BEZAKTIV GO dyes do not only fix rapidly during the exhaust process, but can also increase productivity in the CPB process. Standard dyes normally need a minimum fixing time of 12 – 16 hours in the CPB process. If the dwelling time is shorter,

GO AHEAD WITH BEZAKTIV GO AND TAKE ON RESPONSIBILITY!

not all ternary dyes are fully fixed, so that the colour depth and especially the shade deviates from the setting. BEZAKTIV GO dyes already reach their fully fixed condition at an ambient temperature of 20 to 25 °C after a dwelling time of six hours or less.

DYEING METHODS

BEZAKTIV GO dyes are tailor-made dyes for the ecological and economical GO process. The high fixation values of BEZAKTIV GO enable the washing-off of hydrolysate at 40 – 60 °C in 3 – 4 rinsing baths. The temperature and the number of rinsing baths depend on colour depth, carry-over and liquor ratio. Perfect wet fastnesses are achieved when the process is completed with a cationic after-treatment. In addition, they are perfectly suitable for all common processes in exhaust, semi-continuous and continuous dyeing.

> EXHAUST PROCESS FOR BEZAKTIV GO

The optimal dyeing temperature is 40 – 60 °C. The appropriate dyeing temperature depends not on the dyestuffs, but on the articles and machinery. E.g. for yarn, dense articles or viscose a higher temperature is advantageous. BEZAKTIV GO dyes can be used both on exhaust machines (jet, overflow) and also on exhaust apparatus (cross-package or warp beam dyeing apparatus, beam dyeing apparatus). The recommended auxiliaries and the correct amounts of salt and alkali are given in the following process description.

GO processThe most advanced dyeing and rinsing process is only feasible with BEZAKTIV GO dyes. The reduced temperature leads to an increased process safety due to better control of fixation speed and a reduced hydrolysis of unfixed dye for highest possible

colour yield. If the dosage is monitored, sodium carbonate and caustic soda can be added simultaneously. With progressive alkali dosing a steady increasing fixing curve and therefore the best possible levelness is reached.

> SEMI-CONTINUOUS PROCESS

Woven and knitted fabric made of cellulose or regenerated cellulose can be dyed very economically with the cold pad batch (CPB) process with BEZAKTIV GO dyes. When BEZAKTIV GO dyes are combined with BEZAKTIV V or S, it should be ensured that dyes with the same dyeing properties such as fibre affinity, liquor stability and fixing speed should be used. This information is given in the respective tables. To prevent tailing during padding, a high liquor exchange should be ensured. With lightweight fabrics dyeing should be performed with a low trough level and a high running speed. A low liquor stability can result in tailing. To ensure a high liquor stability it is highly recommended that the temperature of the padding liquor is not higher than 25 °C. Dye and alkali solution with a 4:1 ratio are combined just before the padder with a mixing pump or doser and added to the dye trough. The application amounts of dye, auxiliaries and fixing alkalis are based on the overall volume of the padding liquor. It is important that the fabrics have been cooled properly before padding to ensure reproducibility. If the fabric tem-perature is too high, the liquor stability is lowered which results in a change of colour or its depth. A constant production speed should generally be ensured. Different speeds influence the liquor pick-up and result in tailing. During dyeing the fabric is rolled with a straight line fabric. In order to ensure optimum fixation of the dye, the dyed goods must be packed with an air-tight plastic film and left for a certain time at room tempera-ture. Packing the goods with an airtight package prevents carbon dioxide from the air partially neutralising the fixing alkali. When dyeing with several dyes the dwelling time of the dye with the longest dwelling time should be taken.

Cold pad batch process with reduced sodium silicate quantityThe reduced silicate version is the standard version and has a high pad liquor stability in the temperature range of 20 – 30 °C. The application amount of sodium silicate 38 °Bé is generally 50 ml/l. Addition of the dye with the fixing alkali is performed with a mixing pump with a ratio of 4:1. To prevent silicate deposits on the rollers, intensive rinsing before neutralisation is essential.

Mixing ratio: The stated quantities g/l of dye, ml/l of sodium silicate and ml/l of caustic soda 32.5 % (38 °Bé) are based on the total volume of the padding liquor. Dye and alkali solution are combined with a mixing pump with a normal mixing ratio of 4:1 and form the total padding liquor volume.

Dwelling time:6 – 24 hours, up to 40 hours no colour loss-es or shifts in shade occur.

Table information: The given dye specifications were deter-mined with use of the reduced sodium silicate method (50 ml/l) and caustic soda 38 °Bé with 30 g/l dye at a padding and dwelling temperature of 25 °C.

Fibre affinity:The fibre affinity was determined by adding alkali and characterises the specific exhaus-tion properties of a dye. To avoid tailing problems, the use of dyes with the same fibre affinity is advantageous.

Padding liquor stability:The padding liquor stability is given in minutes. A period of time for hydrolysis of 10 % of the employed dye is determined. This theoretical value cannot be implemented directly in practice, as the dye and alkali solution are constantly added to the trough. For this reason the actual value of the liquor replacement in the trough should not exceed three minutes. The values of the BEZAKTIV GO dyes were determined at a temperature of 25 °C and with the use of the reduced sodium silicate variant. A higher temperature and different alkali systems influence the liquor stability.

The BEZAKTIV dyes are categorised as follows:Low < 10 minutesMedium 10 – 20 minutesHigh > 20 minutes

Fixation speed:The speed of fixation depends greatly on the dwelling temperature. A regular temperature of the dyed fabric, liquor and environment is a requirement for regular fixation. The stated values of the BEZAKTIV GO dyes are based on an ambient temperature of 25 °C during dwelling. If the ambient temperature is lower, the dye is fixed more slowly. For this reason it is necessary to adapt the dwelling time accordingly.

The BEZAKTIV dyes are categorised as follows:Slow > 16 hoursMedium 8 – 16 hoursFast < 8 hours

> CONTINUOUS DYEING PROCESS

Pad dry pad steam processThe pad dry pad steam process is the classic continuous process for dyeing woven fabrics. It is primarily used for cellulose articles with a high yardage. This process is characterised by a high productivity, a good fabric appearance as well as a good colour yield. The use of a dosing pump is not necessary with this process.

Pad dry thermofix processThe pad dry thermofix process is a single-bath and salt-free continuous process. Particularly suitable for light to medium shades. A lower light fastness level is achieved compared to the pad dry pad steam process. No dosing pump is required for this process. Fixation is performed with hot air. Sodium bicarbonate is recommended as a fixing alkali, because of higher liquor stability than sodium carbonate.
