Reactive Dyes-use

Application of R type reactive dyes

two-bathing pad dyeing

1, Procedure

    pad dyeing liquid (residue: 70%)→pre-drying→drying, →immerse and pad →steaming(102-105°C, 40-60s)→washing→soaping→ water washing→drying

2, Formula

Dye x g/L
antimigrant 1-2 g/L
penetrant 0-2 g/L

Formula of mixed basic liquid:

NaOH(36°Be') 12-15 ml/L
Na2CO3 20-40 g/L
NaCl 150-200 g/L
reserve salt S 10 g/L

one-bathing pad dyeing

1, Procedure

pad dyeing liquid (residue: 70%)→pre-drying→drying, →immerse and pad →steaming(102-105°C,5min)→washing→soaping→ water washing→drying

2, Formula

Dye x g/L
antimigrant 1-2 g/L
urea 30-100 g/L
soda 10-40 g/L
reserve salt S 10 g/L
penetrant 0-2 g/L

Dip-dyeing

1, temp.-increasing method: ( medium and dark color dyeing of thin fabrics)

2, shift-dyeing method:(for light color or fabric with bad leveling capacity)

3, constant temp. method: (for auto machine dyeing)

4, thermal variation method: (for thick fabrics)

Washing process

1, method: cold washing→hot washing→(neutralization)→soaping(1-2times)→hot washing→cold washing

2, condition: anion or non-ion detergent

                1-2g/L     soaping agent                                                          2g/L     Ratio, temp., time          1:10-1:20              95-98°C×20min     neutralization: acetic acid or formic acid to PH=7-8 Dosage
