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.

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.

Shade Band
We need at least 50 pcs garments including all shades.
We complete these garments as per standard recipe for this first 50 pcs
After completing shade band, we submit it to buyer QA, who is responsible for shade band approval. Read more about Terry Towel Weaving Machine
First Bulk
Just after getting the shade band approval, we go for first batch approval and always maintain 1st batch procedure.
The same team, who reviewed the blankets, selects the garments from all lot.
We take 32 pcs in each with identification marks.
Then we pull out 12pcs of each shade.
Then out of this, pull out 6pcs in each shade and wash as 1st trial. At first we follow the buyer recipe. If need we make some adjustments. Otherwise our wash technician follows the same recipe as they used for blanket and shade band.
Then this 18pcs garments review by dyeing in-charge, washing in-charge and quality in-charge of the laundry under CWF light sources in the color matching room. If 1st trial is OK, the well. If not, then we go for 2nd trial. So that we can go closer to main standard.
We must keep standard each section signed by dyeing in-charges and each section QC table signed by QA manager.
After completing the dyeing we test the garments as per buyer requirements.
Then we submit for approval which is closer with standard. After getting the approval we go for bulk production.
Quality procedure
If not meet the standards then make NCMPR for decision and inform the garments factory.
After Wash we check the garments
Before starting the sampling/bulk we need the measurement sheets for all size of the garments for random checking.
Grey mélange dyeing using by disperse dye on CVC (60% Cotton +40% Polyester). This mélange effect done by dyeing of Polyester part (Disperse dyeing). Most of the cases not possible by cotton part dyeing (Reactive dyeing)
Cotton part dyeing (Reactive dyeing) mélange effect is highly encouraged.
Limitation:
Irregular work that why we don’t stock any disperse dyes to avoid any bad stock.
After getting order we request to supplier for loan. Supplier collect dyestuff from different factory and give us loan. So dyestuff lot different occurred.
If we procure from manufacture it takes long lead time. otherwise we have to do air shipment by make extra cost USD 5.0/kg(additional charge)
Cost of disperse dyes is high. Let say 35-45 USD/kg. So process cost is higher.
By our previous experience this type of shade makes some running shade in the fabric.
Different yarn lots produce different shade.
Though this yarn price is less but process cost is high and rejection occurred. So total fabric cost becomes higher.
Pilling result becomes poor, like 2-3.
Benefits of Mélanges made by Cotton + Viscose/Huafu/Bross
No Pilling issue.
Colour fastness should not be an issue.
Though yarn price is high but due to less process cost and less rejection, fabric price will be cheaper(Matter of debate)
Conclusion
How to Keep Black Jeans from Fading Machine – by considering above limitation is highly encouraged to take grey mélange yarn by cotton part dyeing or by reactive dyeing or dyed mélange.
To determine the durability of prints, pigments, flocks,
motifs and add-ons, for the lifetime of the garment.
PRINCIPLE
A finished garment or fabric specimen of specified minimum
size is subject to a prolonged wash in a Hoover side impeller or Durawash
washing machine. It is assessed against
an untreated specimen for deterioration in appearance.
APPARATUS
Hoover side impeller, top loading, non- automatic washing machine (single or twin tub), 40 litre capacity. or Durawash
ECE detergent/sodium perborate
Polyester makeweights (ballast) as specified in BS EN 26330
Grey Scales for assessing change in colour BS EN 20105 A02
Veri-Vide light cabinet (or equivalent) with lectern
Thermometer
Timer
Overlocking sewing machine
Balance
CONDITIONING & TESTING ATMOSPHERE
It is not necessary to condition the samples nor carry out
the assessment or testing in a standard atmosphere. Ordinary room conditions
are satisfactory so long as the correct procedure is followed.
TEST SPECIMENS
Cut at least one specimen for testing (minimum size 300mm x 300mm of fabric, or one complete garment plus duplicate for comparison). Complete garment to be tested where possible.
Overlock any raw edges of woven fabric to prevent fraying.
PROCEDURE
Fill the washing machine with 40 litres of clean water & heat to 40+/- 2 degrees C
Add 160g ECE detergent/40g Sodium Perborate and run the machine for two minutes to dissolve the powder.
Add the test specimens, made up to a total 1kg load with polyester makeweights (ballast)
Run the machine for 15 minutes, remove test specimens, rinse once in hand hot water and once in cold water to remove any surplus detergent, spin to extract excess water
Flat dry specimens in dry air not exceeding 60 degrees C
REPORT
Report the numerical grade recorded together with the reason
for any down grading. General deterioration in appearance, loss or change in
shade, delamination etc.
NOTE
Where all assessments are satisfactory the overall result of satisfactory is to be given. Polyester makeweights must be thoroughly cleansed between tests to ensure no contamination.
Defect Recognition and Consistency
At Auto Sportswear,
we strongly believe that one of the more effective ways to establish
consistency in classifying defects, is to hold frequent Major / Minor
exercises. These sessions are a review of selected garments with marginal
defects. Inspectors rate the defects privately and the QC Manager leads a recap
discussion with the group determining how each should be classified: major or
minor.
Group discussion should be encouraged and all QC Inspectors
should participate, including Piece Goods Inspectors. By sharing with and
observing from one another, Factory Inspectors will begin to think more
alike. Improving Inspector consistency
throughout the factory and becoming consistent with the Auto Inspectors, will save needless failures. This
in turn will save time and money.
This is a valuable and quick exercise that the factory
should hold routinely throughout the year.
Exercise Leader Instruction
Complete Major / Minor Session with factory example garments and inspectors completing the Defect Tally Sheet. Lead class discussion and get consensus on each garment.Have students participate and use the defect standards to
classify each defect.
Defect Standards Library
In addition to the Major / Minor Sessions, the factory QC
management should maintain a Defect Standards Library to train factory personnel
and to assist QC Inspectors in determining acceptability of challenging
problems. The library should be made up of major and minor defects that
primarily set the standard or limits for acceptability.
To assist in the establishment of this library, we’re providing you with a copy of a collection of fabric defects and common quality sewing problems. End of Impeller article
