The factory management must hire an outside consultant for implementation of WRAP standard and make its compliance. The factory management has to adopt all the principles and have them in place, with documentation, for a minimum period of 45 days before it can request a WRAP Evaluation. When the facility’s management is confident that it is in compliance and satisfies the documentation requirements outlined in the self-assessment handbook, it may contact an independent WRAP-accredited monitor to schedule an inspection. Read more about What is Melt Index Tester? How does it Works?
The factory will pay the Independent Monitor’s fees and will determine the fee and scheduling directly with the selected Monitor. The Monitor will conduct the evaluation at the mutually contracted time and report the preliminary findings to the factory management and WRAP. If the facility satisfies the compliance requirements, which includes a favorable recommendation by the Independent Monitor, it will then submit a written Certification Recommendation
Bleaching for Processing of Cellulosics
Cellulosics and their blends with synthetics could be desized, scoured and bleached in a single stage. This could reduce the processing time by a considerable extent, apart from reducing the water consumption and wastewater generation.
This measure has been implemented in number of units in India, particularly for the batches where the final dyed product is of a dark shade. In these situations no adverse effect on the quality was observed. The improved environmental impact is due to the fact that all three processes could be carried out in just one bath (instead of three different baths for thrice the duration and having rinses in between). Furthermore, as in earlier mentioned options, the industry concerned would need to make a few trials before commercial implementation.
Reduced process time and energy
Reduced water consumption
Reduced wastewater generation
Reduced cost of effluent treatment
Applicable for cellulosics and their blends only. Combined process for desizing, scouring and bleaching is particularly suitable for fabrics in dark shades, where the bleaching requirement is low. However, this could also be applied for medium shades, depending on the efficiency of the combined process.
The savings are obvious because of the reduction in the number of stages as well as the process time and water.

Compliance
How much time does the facility have to complete an audit?
Facilities have six months from the time of payment to complete their audits and have their monitoring reports and recommendations submitted. If the auditor indicates that the facility is not compliant with all 12 WRAP principles and requires corrective action, then the corrective action must also be resolved within the initial six-month time frame. Read more about What is Melt Index Tester? How does it Works?
If the facility is under corrective action, does it have to
repay the registration fee?
If the facility can remedy and resolve the corrective action
issue(s) within the initial six-month timeframe, there is no need for
repayment. However, if it takes longer than six months to address and remedy
the corrective action and to complete the audit, yes, the facility will need to
re-register and repay the fee again.
If the facility is under corrective action (CAP), how long does the factory have to be in compliance before the monitor returns to re-evaluate the facility?
Liquor ratio in textile dyeing
The liquor ratio is the amount of litres of used water per kg processed fabric. For instance, if 500 litres of water are needed to process 100 kg of fabric, the liquor ratio is 5:1. If changes in the production process mean that only 300 litres of water are needed to process the same amount of fabric, then the liquor ratio is reduced to 3:1.
It is important to keep the liquor ratio at a minimum when dyeing and rinsing in discontinuous processes. On the other hand, it is important as well to be able to easily adjust the production process to changing demands.
In principle, when choosing a dyeing machine, the one with the lowest liquor ratio is preferable. Consideration must be given not only to the use of jiggers, air jets and jets in comparison to reel barrels, but more generally to the proper selection of dyeing machines with comparable characteristics.
Once the dyeing machines have been selected, it is important to operate them as efficiently as possible. In case the bath volume can be selected within wide margins, it is important to limit the amount of water used to the extent possible.
A decrease in the liquor ratio can be achieved through:
• Decreasing the volume of the dyeing machine and preventing dead corners (without material);
• Installing displacement devices, so the machine can be filled with less liquid;
• An improved way of stacking and operating the machine at maximum load (compressing the material).
The liquor ratio can further be adjusted to the load using air. In this case, a spin-off advantage is the improved fixation of the dyestuff to the fabric.
Operating at a low liquor ratio not only reduces energy consumption, but also the consumption of water and chemicals. By incorporating a displacement device a volume reduction of approximately 50% can be achieved in the processing bath.
The applicability of this measure depends on the production capacity per dyeing barrel and the capacity of the transport system in the machines to prevent creasing or deformation of the fabric. Since dyeing is the most critical process in the finishing stage, reducing the liquor ratio is primarily applicable in low risk rinsing processes. This aspect should be taken into account when deciding on replacing equipment.
The industry concerned would need to make a few trials and assess quality impacts before commercial implementation.
Savings can be achieved on raw materials as well as auxiliary materials and wastewater charges.
In case a displacement device is included in the dyeing machine when it is installed, the costs are limited to approximately EUR 2 000 (INR 112 000) per device. However, in case they were not installed initially, then the costs could be 10 times more because significant construction changes may be necessary.
Conclusion
High temperature lvdt facilities must be in compliance for 45 days before the monitor can return and re-evaluate the facility.

Request for Certification
The Certification Recommendation will be submitted with all relevant materials to the next scheduled Board of Directors Certification Review Meeting for certification. Upon certification, the facility will receive immediate written notification of certification, valid for a one-year period. To maintain certification, the production facility will receive unscheduled visits by accredited Independent Monitors during the period of certification. The number and frequency of the follow-up evaluations will be determined by risk-based program criteria and the conduct of the facility. Risk- based criteria will be weighted to how a factory consistently satisfies compliance requirements as evaluated by an Independent Monitor.
Why Garments wash?
Washing is must in textile technology for many purposes. Like-
Washing process of garments is done to create wash look appearance. After wash garments create a new looks which seems the touch of fashion.
By the washing technology, Faded/old look, color or tinted affect is created in the garments, which also seems the best touch of garments.
Washing technology creates new fashions such as deep dye, tie-dye, tagging, grinding, destroy and many others.
It removes many hazardous impurities like grease, wax, enzyme, alkali, bleaching agent, oxidizing agent etc from garments to prevent producing hydro-cellulose and oxi-cellulose. If the impurities remain in the garments, it could be harmful for our health.
It also reduces the size materials as a result the garments become size free and make it soft hand feel.
To attract the customers/buyers by different types of fashionable washed tems and market development.
Due to washing, shrinkage occurs in the garments. There is possibility of further shrinkage.
Any dirt, spot or germ if added in the garments during manufacture, is also removed during washing.
During garments cutting, 15% garments is cut out as wastages, if this 15% garments is cut out as grey garments, the wastage cost will be saved.

Compliance
Yes, certification can be denied, revoked or reclassified if the production facility does not fully satisfy the requirements of compliance with the WRAP Principles. The Independent Monitors are to verify that the production facility is in compliance with the WRAP Principles and Procedures before a Certification will be granted. The Independent Monitor will review its evaluation with the plant management and submit its findings to the Certification Board and/or explain what corrective action(s) must be undertaken by the facility, if necessary, for management practices to demonstrate full adoption, deployment and monitoring of the WRAP Principles. Only when this is verified through the onsite evaluation will a facility be able to request certification. Plant management has six months from the date that WRAP confirms receipt of application, to put the plant into compliance and make a written request for Certification. After six months elapse and the factory has not been certified it must initiate the process all over.
Certification is valid for one year only. Certified Facilities may be
subject to unscheduled follow-up evaluations during the one year term of
certification. The number and frequency of unscheduled follow-up visits will be
determined exclusively by the Certification Board, including plant performance
and original certification process.
Risk-based production facilities will receive mandatory unscheduled follow-up
visit(s) during the term of Certification. Any facility can have its
certification revoked or placed risk-based status if it is not found to be
systematically in compliance with adoption, deployment and monitoring of the
WRAP Principles.
Before a Request for Certification is filed with WRAP, the
production facility must satisfy the compliance requirements verified with an
evaluation by one of the accredited Independent Monitors.
