solution prepare in the room temperature.
Then increase the temperature till 95⁰ c at raising rate 0.5/⁰ c and hold 10 minutes. Again,
Increase the temperature 115⁰ c at rate 0.5⁰ c/min and hold 10 minutes. After 10 minute
increases the temperature 135⁰ c and hold 40 minutes.
After 40 minutes we drain the goods with softener Impreza.
if softener use then material is soft.
NYLON DYEING CYCLE
FOR 1200&900 DENIER
First load the material in vessel. Then scoured with scouring agent 20 minute at 110⁰ C
temperature. After drain we prepare the solution in room temperature with levelling (lysogen
S.E),
retarder (Ammonia) and penetrating agent (C.I.R). And color.
After preparing the solution we increase the temperature 60⁰ C

17. At rate 0.5⁰ C/min and hold 10 minutes. Then again and again increase the temperature same
rate 80⁰ C to 107⁰ C.
After drain we use the softening agent for smooth and soft touch
OLD DYEING
DYEING M/C CAPACITY
HYDRO M/C

18. Hydro extractor or centrifugal extractor use centrifuge technology for manufacturing
laundering which is used in Textile Company. Hydro extracting m/c is mainly centrifugal for
generating hydropower. The wet substantial is placed in the hydro extracting m/c or centrifugal
extracting m/c which has a barrier of metal generally steel. The internal drum of centrifugal
extracting m/c switches at high speed thus throwing out the water contained in it. The use of
this extractor considerably decreases the energy required to dry any material. It is special types
of washing machine. Through our technique apartment hard work, exploit new the leading level,
and the national patent. This extractor is used after dyeing machine and before tumble dryer
machine.
POLYESTER DYEING CYCLE
NYLON DYEING

19. Mostly nylon dyeing is carried out in hank form, for this purpose we use Fadis m/c.
M/C CAPACITY
Fadis m/c
Co. Name - Solbiate ARNO(VA-ITALY)
☆ This m/c convert package to hank.
☆ There are total 72 m/c,whose capacity 10 spindle ,
6 spindle ,and 8 apindle
☆ The conversation of package to hank depend upon m/c speed and yarn quality (denier).
The quality of threads is colored in nylon dyeing

DYEING CYCLE
Theory
Acid dyes are highly water soluble, and have better light fastness than basic dyes. The textile
acid dyes are effective for protein fibers such as silk, wool, nylon and modified acrylics. They
contain sulphonic acid groups, which are usually present as sodium sulphonate salts. These
increase solubility in water, and give the dye molecules a negative charge. In an acidic solution,
the -NH2 functionalities of the fibers are protonated to give a positive charge: -NH3+. This
charge interacts with the negative dye charge, allowing the formation of ionic interactions. As
well as this, Van-der-Waals bonds, dipolar bonds and hydrogen bonds are formed between dye
and fiber
