Heavy Duty Washing Machine

Heavy Duty Washing Machine – One of the most important options to reduce the environmental impact of industrial processes is to minimize the number of required process steps necessary to produce the desired quality of products. As an example, instead of traditional pre-treatment of textiles, the minimum required treatment processes can be applied. The pre-treatment of the fabrics depends on the desired colour depth and other characteristics of the finished product. For example, fabrics that will be dyed in dark colours should not be strongly bleached.

Oftentimes, reducing the number of process steps is possible through treating the fabrics in wet conditions, without the need to dry them first. This allows certain process steps to be combined which normally are carried out separately. Examples that have been implemented include:

  • Improvement of the feel of yarn directly after painting without drying the material first;
  • Making wool moth repellent during dyeing;
  • Development of a single step pre-treatment of the fabric that combines washing, scouring and bleaching in such a way that one washing / drying stage can be omitted. Depending on the type of textiles treated, one step pre-treatment can yield substantial energy and water savings because two or even three of the wide washing steps can be reduced to one. One-step pre treatment is especially feasible for textiles that are relatively light weight;
  • Wet-in-wet impregnation of treatment chemicals, in order to skip a drying stage. Many treatments of fabrics can be applied directly on the wet cloth after the wide washing process. In that case, the cloth is impregnated “wet-in-wet”, followed usually by a reaction step in order to let the chemicals work on the fabric. Afterwards, the cloth is rinsed on a wide washing machine. Examples of this process include: (1) The wet-in-wet pre-treatment on a continuous pre-treatment line; and (2) the wet-in-wet application of a cationic treatment chemical after rinsing out unabsorbed reactive pigments;
  • Combined dyeing and application of crease repair agents (synthetic resins) so the material only has to be dried once.

For Denim-

  • Yellowish marks come from chemicals & from back staining.
  • Indigo dyes have big molecule structure, so after washes it’s come back to the garments again. Sun lights affect those molecules & make the garments yellow. So we have to wash it clearly and use the anti ozone (O3) softener.
  • To prevent crease marks reduce RPM & temperature at desizing stage.
  • To avoid uneven increase pH. At lower pH bleach work quickly & makes uneven.
  • Use buffer solution to stable pH. For pH changing shades will change also.
  • Hypo must be clear to prevent Yellowish effect

For Dyeing-

  • Important parameters for dyeing-
  • Hydrophilic
  • Base color (bleach slowly for even dyeing)
  • pH
  • Circulation
  • Temperature
  • Anti Ozone softener improves the fastness of Sulpher dyeing. Don’t use any non-ionic softener.
  • To improve the light fastness, protect the surface.


  • To make garments soft, use good desizing agent. Then use micro & macro emulsion together. Dry in the steam dryer.
  • Improve tearing strength by using polyurethane
  • NaHCo3- pH doesn’t change with temperature  
  • Na2CO3- pH change with temperature
  • Polyethylene (LEPN) used for color fastness. It makes the fabrics slippery & hence improve the color fastness (Only rubbing)
  • Densoft Ultra for Sulpher dyes.
  • Densit-AT- acid buffer to stable pH.
  • New Developments-
  • Crinkle Effect on denim garments-
  • Tie the garments inside of a net
  •  Wash at 80’C for 10 mints.
  • Open the net.
  • Enzyme (Neutral) with anti-back staining agent for 30min at 30’C.
  • Rinse 2times.
  • Bleach with KCI (10g/l) at 50’C for 10-12min
