Why yarn from the same batch can still vary
Short answer: Raw material, moisture and machine settings shift a little along the way. That is why two rolls of yarn from the same order can give fabric with small differences in colour and handle. It is normal in textiles and not a sign that anything went wrong in production.
Same order, not quite the same yarn
When yarn is ordered as a batch, you do not get one uniform mass. You get many rolls, spun at different times and on different machines. They lie close to one another but are not identical. That explains why small differences can appear even when everything was ordered at once.
The raw material is not the same every day
The fibres come from different deliveries, and even small differences in length and moisture change how the yarn is spun. That is normal and kept within agreed limits. A raw material of plant origin is never quite the same from sack to sack, and that shows in the finished yarn.
Moisture and temperature
Fibres take up and release moisture from the air, and that changes how they behave in spinning. A day with more moisture in the hall gives a slightly different yarn than a dry day. The difference is small but can be felt in the handle of the fabric, meaning how it feels and falls when you touch it.
The machine drifts slowly
Needles wear, the temperature in the hall changes and the tension is adjusted. Over a week of production that gives a small drift in the result. No machine holds exactly the same settings for long, so they are checked all the time. The aim is to keep deviations so small that they cannot be seen on the finished garment. See Egtved.
What colour does
Colour is the difference that is easiest to notice. A yarn dyed in one bath can be a shade different from a yarn from another bath. The difference can be so small that you only see it when two pieces lie side by side in daylight. Seen separately, they look the same.
Why garments are sewn from the same batch
At the factory, fabric from the same batch is kept together, so sleeves and body come from the same roll. Otherwise two parts of the same garment can each have their own shade. It is a simple rule that removes most of the problem. Take bamboo polos for men, where sleeves and body must match.
What you can see in two garments
If you have two garments of the same model, they can in rare cases show small differences in shade or in how the fabric feels. It shows best in daylight with the garments side by side. Worn separately, you will rarely notice anything. Also look at bamboo underwear for men, where two pairs are often worn in the same week.
Can you reorder the same shade
Rarely. A new batch lies close but not always exactly on target. That goes for us and for the maker. If two garments must match perfectly, it is best to buy them at the same time, so they come from the same batch. It is a simple way to avoid differences.
When is a difference a fault
A difference is only a fault if it is clearly visible in daylight side by side. Small variations within the agreed limits are part of textile production. If you are unsure, take a photo in daylight and send it to us, and we will look at it with you and find out what happened.
Frequently asked questions
Are colour differences between two garments a fault
Only if the difference is clear in daylight side by side. Small variations within the agreed limits are normal in textiles and do not mean the garment is defective.
Can I reorder exactly the same shade
Rarely. A new batch lies close but not always exactly on target, so if you want two garments to match perfectly, it is best to buy them at the same time.
Why does the fabric sometimes feel different
Because the twist and moisture of the yarn vary a little within the agreed limits. The difference is small and mostly noticed only when two garments lie side by side.
