100% cotton crepe single jersey fabric dyeing and finishing process with a complete practical experiment

Cotton crepe single jersey is the newest development in the world. Here we discuss the 100% cotton crepe single jersey fabric knitting process, dyeing process with reactive dye, finishing process, and flow chart of knitting, dyeing, and finishing process with complete practical documentation which I did recently. Now I am sharing my recent development

Dyeing of cotton crepe jersey fabric with reactive dye:

Here we have completed the knitting of this fabric.  Now we have the dye the fabric. We discussed below all the flow processes of dyeing which we did for this batch.

Dyeing process flow Chart:

Short description of cotton fabric dyeing process flow chart:

I am giving here a short description for a better understanding of the process.


Knitted fabric is collected from the knitting gray store and created a batch here. Batch means the prepared fabric in dyeable format. Knitting is done roll to roll. Here fabric creates a rope according to the loading capacity of the dyeing machine. A batch card is also created for storing all the knitting and dyeing process parameters.

Loading to dyeing machine:

It is the 3rd step of the dyeing process. Lubricant is injected into the machine for avoiding friction between the machine and the fabric surface. Then load the fabric. Cycle time, Pump pressure, Reel speed, and Nozzle pressure setting is controlled here.

Scouring and Bleaching:

Normally scouring and bleaching are two different processes in oven fabric. But for knitting fabric, it is done in the same batch. For cotton fabric caustic soda and hydrogen peroxide uses to scour and bleach here.

Bio Polishing:

This is the process to remove the hairiness of the fabric surface Bio polishing is done after the scouring and bleaching state. For special cases, it is also done after dyeing.

It is noted that excess dosing of enzymes can damage fabric strength.

This is why no need bio polishing


A reactive dyeing process is used here. This is one of the best sensitive fabrics (Heavy jersey).  So that it needs special care to get better results. This is why we use a perfect dyeing process. The result of this fabric dyeing process is good to use. I personally use this process in my factory for better results.


In this stage, neutralization is done. Then the unfixed dyes are removed by a soaping agent. Better or high-temperature soaping will give you better fastness properties. But here the dye shade% is low. So that is no need for high soaping. Here core neutralizer is used to get better results. But we can also use only ascetic acid for naturalization.

Special note For crepe jersey fabric:  Lubricant must have to inject before loading the fabric. The cycle time range will be 2min-3min(Not below 2min).

Finishing Process of 100% cotton fabric:

Now we completed the dyeing of this fabric. Now we discuss the finishing process and parameters step by step below:

Finishing flow chart:

finishing flow chart

Short Description of the flow process stages for better understanding:


After knitting the fabric we get a tube-format fabric. But we have to use an open stenter and compacting machine to get better results. So that the fabric needs to open. This is why we use this machine to open this fabric.

Setting parameter And result:

Machine speed40
Padder Pressure1.5
Fabric In Diameter30 Cm (Tube)
Fabric Out Diameter150 Cm ( open)

Relax dryer:

To control the recovery we need the relax dryer instead of stenter machine. Stenter can damage the crepe effect. We have to pass the fabric as relaxed as possible. We dry the fabric and control the dia, GSM, and shrinkage. For this, we need to appropriate setting. I am giving the setting which I did for this batch

Setting parameter:

Relax dryer parameter
SettingSpeed 18
Dia 190
Tem 110
Padder Pressure 59%
Padder Pressue3+2
After dryerDia 188
GSM 180


Full dia, gsm, and shrinkage are controlled here. Better appearance and looking are done here. The overall quality of dyeing is controlled here.

I am giving the parameter which I did for the subjective batch.

Compacting Parameter
Common SettingOverfeed35% 
Steam Pressure30
Dia 200 188 190 189
Gsm 180 180 180
 Tumble dryLength-9% 

Now the fabric is sent to the testing lab for all the test reports.

Overall Comments on 100% cotton crepe jersey fabric development:

After analyzing all the test reports I can say that the GSM of the fabric is good. Normally we tolerate +/-  5, We do not get the accuracy. We need palla to wash to control shrinkage.


Crepe single jersey is the newest and special type of dyeing fabric development. We need to be careful about its shrinkage and crepe effect. I think this fabric will get popular in the world.
