100% Polyester Fabric All Color Standard Recipe and Dyeing Process

100% polyester is a synthetic fabric. The fiber formation is polyester. The most popular dye is dispersed dyestuffs. The fastness properties are much better than other dyestuffs. Here I am discussing the standard dyeing recipe and standard dyeing process in the textile industry. I am sharing my 100% applied process. Anyone can use it for production and I think it will be your best process.

100% polyester fabric dyeing standard recipe:

Dossing of all the chemicals depends on the concentration of the chemicals and according to the manufacturer’s technical datasheet. On the other hand, dyes depend on the target shade.

Buyer :		Quantity :
Fabric Type : 100% Polyester ( S/J )		Color: Graphite
Step	Type of Chemicals	Dossing	Process(Temp/Time)
Loading Hot	Detergent	0.5 g/l	60’C                L:R = 1:6
			L:R = 1:6
Levelling	Organic acid	0.30 g/l	60’C
	Acid Buffer	0.50 g/l	PH : 4.10
	Polyester leveling agent	1.00 g/l
			L:R = 1:6
Dyeing	Disperse dyes	0.01%	135’C X 45 MIN
	Disperse dyes	0.11%
	Disperse dyes	2.00%
			L:R = 1:6
Reduction	Reduction chemical	2.0 g/l	90’C X 20 MIN
			L:R = 1:6
Softener	Organic acid	0.2 g/l	50’C x 15 min;
	Polyester Softener	1.00 g/l	PH: 5.5

Standard dyeing process of 100% polyester fabric

This is a dispersed dyeing process. 100% polyester dyeing process is a thermodynamic dyeing process. There is no useful bonding is created between the fiber and fabric. Here dyes are interrupted between the fiber molecule. The updated and best production considering process is stated below:

Load the fabric

⇩

POLYESTER PART START

⇩

Oxalic acid+Detergent Inject = For remove impurities and neutralization

⇩

Run time 10min

⇩

Drain and wash for 5min

⇩

Acetic acid inject= For Control PH: 4.2 to 4.5

⇩

Rice the temperature at 80⁰C

⇩

Disperse dye stuff dossing 30min = For polyester part dying

⇩

Rise the temperature80 ⁰C to 95⁰C Grade 1⁰C = Grade for better penetration

⇩

Then rise temperature 95 ⁰C to 135 ⁰C Grade: 0.5 ⁰C

⇩

Run for 45min

⇩

Cooling at 135 ⁰C to 95 ⁰C grade: 1 ⁰C

⇩

Then 95 ⁰C to 79 ⁰C directly.

⇩

Check the sample = To achieve the required shade

⇩

If the shade ok then drain the dye bath

⇩

Normal hot at 80 ⁰C

⇩

Run for 10min

⇩

Wash for 10min

⇩

Caustic soda dossing 8min at temperature 50 ⁰C

⇩

Run for 5min

⇩

Rise the temperature at 80 ⁰C

⇩

Inject hydrose = for removing the loose disperse dyes

⇩

Rise the temperature at 90 ⁰C

⇩

Run for 10min

⇩

Cooling at 80 ⁰C and drain

⇩

Normal not at 90 ⁰C for 10min

⇩

Wash for 10min and drain

⇩

Softener (Polyester) Inject

⇩

Run for 10 min

⇩
