How a fault is traced back to production

Short answer: Every garment belongs to a batch, and the batch has a number. With the number you can find the fabric roll, the sewing line and the date, and from there see what went wrong.

Every piece belongs to a batch

When a garment is made, it belongs to a batch, a group of goods produced together with the same fabric, machines and people. The batch gets a number that follows the goods all the way. It is the foundation of all tracing, because it links a single item to the shared history behind it.

The number is the key

Without a batch number, a fault cannot be placed. You only know that an item is poor, not where or when it was made. With the number, the factory can look up its records and find the fabric roll, the sewing line and the date. A vague suspicion becomes a concrete case that can be examined step by step.

Where the number sits

The number sits either in the label or on the box the goods arrived in. If it is in the label, it travels with the garment to the customer, so a complaint can refer directly to it. If it is only on the box, it must be noted on arrival. So it is wise to keep the label or take a photo of it.

Fabric or sewing

If the fault is in the fabric, the trail points to the dye house and the knitting mill. If it is in the seam, it points to a particular sewing line. The difference matters, because it decides who must put it right. A colour fault cannot be sewn away. See also the Copenhagen Bamboo collection.

The trail to the fabric roll

Fabric comes on rolls, and each roll has its own history. If you find that the fault only appears in goods from one roll, you can name the cause quickly and leave the other goods in the batch alone. That saves time and money, and it stops good goods being scrapped for no reason.

The date limits the damage

If you know which day the fault occurred, you also know which other pieces may be affected. A machine that ran wrongly for two days has affected everything from those two days and nothing before or after. The date makes the damage smaller and easier to survey. See also Urban Quest and CCDK.

From fault to change

Once the trail has been followed to the end, the fault must lead to a concrete change. Perhaps a machine must be reset, a supplier replaced, or the check moved earlier in the process. Without that change, tracing is only an explanation, and the same fault will probably return in the next production run.

When the trail ends

Not every fault can be traced. Some arise in transport or in storage, where there is no trail to follow because nobody noted what happened. A dropped box or a damp warehouse can damage an item without anything showing at the factory. So the trail sometimes ends without a clear cause.

What you can do as a customer

As a customer, you help tracing by keeping the label and noting when you bought the item. Write to customer service with your order number, size and a photo of the fault, and mention the batch number if you can find it. That makes it easier to link your case to a batch and find the cause.

Frequently asked questions

Can every fault be traced

No. Some arise in transport or storage, where there is no trail to follow, and in those cases the only option is to prevent it in future.

How long is the information kept

Typically for several years, so a late complaint can still be investigated. Exactly how long depends on the factory and on what was agreed for that product.
