Higher winding out put due to entanglement-free yarn treatment.

Mechanical mixing and heating of bath without disturbing the yarn.

Can be coupled for maximum flexible operation.

1. Reduced yarn handling.

2. High and uniform rates of liquor circulation, leading to level application of dyes.

3. Low liquor ratios, giving savings in water, effluent and energy.

4. High temperature dyeing is possible.

Hank Yarn Drying MachineContinuous Dryer suitable for 54", 72" and 90" hank length of various materials like Cotton, Wool, Silk etc.

The yarn is carried on stainless steel carrier rods and the heating media is steam or hot oil circulation.

The dryer is highly energy efficient. Variable airflow and machine speed.

Can operate at maximum efficiency and dry yarns at low temperatures. (80 oC in the case of cotton).

The 'second generation' RF with 'intelligent vacuum' ensure very low drying temperatures (approximately 65 oC) and with smaller generators.

Package Yarn Drying Machine

Right First Time Approach

• Process water quality• Selection of dyes/ auxiliary• Liquor ratio• Auxiliary dosage• Steam quality• Bleaching bath stability• Liquor Circulation• Winding parameters and

pressing density

• Temp (Process/ steam)• pH and Dwell time • Liquor circulation/ flow rate• Effective washing off• Residual peroxide killing• Proper neutralization• Number of contacts with

liquor

Problems in ProcessingCSP down 1. Oxy-cellulose formation 2. Residual peroxide 3. Higher alkali/ peroxide 4. Over dryingShade variation 1. Poor absorbency/ whiteness 2. Improper washing off/ dye fixing/ RC 3. Residual peroxide/ alkali after pretreatment 4. Improper reduction/ oxidation of vat dyes

Problems in Processing

Unlevel dyeing 1. Water quality 2. Density of hank/ package 3. Liquor flow rate / direction (I/O: Co/PE 3-4 kg & Wool: 2-2.5) (O/I: 0.5 kg less of I/O) 4. Improper penetration of dyes/ auxiliaries 5. Residual alkali/peroxide after bleaching 6. High affinity of dyes towards fibre 7. Improper reduction/ oxidation of vat dyes

Preventive Action

Remove entrapped air and increased penetration properties: Zywet PDG liq.

Residual peroxide killing using enzymes: Ultrox EPN Premium, Ultrox EPN Supreme

Reduce water hardness and chelate out dissolved metal ions: Zyquest AS, Chelate D, Kleerix PER liq.

Preventive Action

• Use good scouring cum wetting agent: Kleenox PSF/BAS/WLF Conc./LFAF

• Dye bath conditioner as levelling and alkali shock absorber: Zycol PCSN B, Zycol SNE, Zycol PR-SK liq.

• Suitable levelling agent: Krisil RLA, Krisil AB, Krisil VL Extra, Krisil LAN

Preventive Action

• Use suitable washing off agent Zycol SNE/ PCSN/ Vat 100, Neutraclear RC

• Use dye-fixing agent like Hifix NFI Conc. Zyfix R.

• Choice of suitable OBA and softening agent preventing yellowing.

• Proper Hydro extraction prior to drying.
