Chemical Consumption for Dyeing Fabric

Chemical consumption

Chemical consumption are the main ingredients used with dyes and auxiliaries means the aids or helper to get better results like levelness, adsorption, crease free and other quality parameters. But WATER (H2O) is the important  ingredient needed in all dyeing…

Chemical Materials Calculation

laboratory dyeing machine can dye fabric, yarn or even some accessories like button, zipper and loose fibre but main products are the knitted fabrics. Knitted fabrics have different constructions and GSM (weight of fabric in one square meter) and this have different dye pick-up or adsorption. Table given below shows the common fabrics produced at and used in laboratory.

Style Blend Finished GSM
Single Jersey (SJ) 100%  cotton 115 – 270
Single jersey (SJ) PC and CVC 100 – 300
Back Pique/La Coste 100 % cotton/PC/CVC 150 – 250
Polo Pique/Honey comb 100% cotton/PC/CVC 150 – 240
Jumbo Pique 100% cotton 200 – 250
Twill pique 100% cotton 180 – 250
Bubble knit 100% cotton 200 –250
