100% Nylon Fabric Dyeing Process With Acid Dyes

Nylon fabric dyeing process

The nylon fabric dyeing process is an exclusive dyeing process in the textile industry. There are different nylon dyeing method is available to use. Today I am discussing the nylon fabric dyeing process with acid dyes. These acid dyes are effective for protein fiber.

As a result wool, silk, nylon, and modified acrylic can dye easily. Acid dyes has also good fastness properties than basic dyes. Acid dyes are highly soluble in water and create a negative charge and interact with the positive charge of fiber. As a result, Van-der-Waals bonds, dipolar bonds, and hydrogen bonds are formed between dye and fiber.

Some related questions and answers about the Nylon dyeing process:

  1. How do you dye nylon fabric?
  2. Does fabric dye work on nylon?
  3. Can you dye nylon mesh?
  4. What is the fabric dyeing process?

Answer: 1. Nylon fabric is dyed with acid dyes. 2. Yes fabric dye work on nylon. 3. Yes nylon mesh can dye easily. 4. The nylon dyeing process is given below.

100% Nylon Fabric Dyeing Process:

Dyeing of nylon fabric with the acid dying process is below step by step-

Load the fabric

Normal hot with oxalic acid and detergent

Raise temperature to 70⁰C

Run time 10min

Drain & fill

Leveling (PH=4.50-5.0)

Dyes Dosing 20-minute Temperature 40⁰C

Runtime 10 minute

Temperature Increase 98⁰C (1⁰C/minute)

Runtime 30 minute

Colling 80⁰C (1⁰C/minute)

Shade check

If everything ok then

Bath Drain

Cold rinse 10 minute

Soaping agent Inject (pH5.00)

Raise the temperature to 80⁰C

Runtime 15minute

Cold wash10 minute

Fixing

Cold water wash 15 min

If the water is clear then

Softener   (pH 5.00-5.50)

Unload

Process Description Of Nylon Dyeing Process:

In the nylon fabric dyeing process, Load the fabric at a normal 30⁰Ctemperature. Firstly hot the fabric at 800c with oxalic acid and detergent to remove the dust, dirt, iron, etc. Then Control the ph between 4.5-5. Inject the leveling agent and raise the temperature to 40⁰C. Dossing the dyes for 20min.

After that rise, the temperature was 980c with a grade of 10c per minute. Here grade is essential for better leveling of dyes stuff. Run here for 30min. Cooling at 80 with grade 10⁰C per min. Check the shade with the required standard. Drain the dying bath if the shade is ok.

If it a not ok dye can add to the dye bath and rise the temperature again. shade check after cooling the at 800c. If ok then drain.

Here rinse with a need of up to 10min to remove the loose dyes from the fabric surface. Speaking needs according to shade %.

Finally fixing agent is used for better fix-up of acid dyes and unload the fabric with ph 5-5.5.

Conclusion:

This Nylon fabric dyeing process is using many reported factories for production. They get better results from this process. My tips and tricks for using this process for better results-

  • PH must have control properly.
  • Should not use temperature upper than 100⁰C.
  • Stenter and dryer should be at 100⁰C.
